Ontario Chapter

The fall issue of the Access Canada magazine is by far our largest undertaking to date with 1500 copies printed with 1200 being distributed across Canada and USA with 300 for distribution at the upcoming

Construct Canada trade show.

The SIAC will be exhibiting at the Construct Canada trade show to be held at the Metro Convention Center in To-ronto, November 28-30, and with over 25,000 visitors expected this years show promises to be bigger than ever.In conjunction with the show we will also be holding our own General Meeting on Wednesday 28th with several presentations planned on safety, training and new products. All members are wel-come and further details will be distributed nearer the time, so mark the date on your calendar.

Our participation in Construct Canada would not be possible without the contribution made by several companies, especially Etobicoke Ironworks for the supply of system scaffold product that are used to con-struct the temporary archways for the show, Stephenson Rental Services and Dufor Scaffolding for their assistance with labour and logistics and also those other member companies whose valuable sponsorship is greatly appreciated, and of course those individuals that contribute

with their time and effort to ensure that we have a successful show.

The article on Legal Issues is a must read for everyone involved in not only the scaffold industry but all other industries. The comment on employer’s responsibilities with respect to hiring that competent per-son and subsequent action that is required undoubtedly applies to many companies, as does the legal requirement for a detailed understand-ing of all OH& S statutory obligations that apply to your workplace.

I recently attended for the first time the annual convention of the Mu-nicipal Health and Safety Association Ontario in Toronto and was more than impressed with the amount of time dedicated to safety aware-ness and training in the workplace with many industries represented, with the exception of scaffolding. This we will remedy for next years convention as we will be participating as an exhibitor and providing scaffold user basic training sessions during the three day convention. On September 01, 2007 Canadian Standards Association (CSA) imple-mented new and revised CSA standards for fall protection that included, full body harnesses, lanyards, energy absorbers and lifelines. As there are some significant changes in equipment specification and usage, all SIAC members and employers should ensure that they are fully conversant with these revisions and that any necessary training is provided to their employees.

Although used fairly extensively in many European countries “Ad-vanced Guardrails Systems” are not used to any extent in North America, although that may change in the coming years as fall prevention by this system is the ultimate solution for fall protection, and provides a practi-cal safe solution to certain legislation that calls for the scaffold erector to be “tied off at all times” during construction of the scaffold structure. The SIAC is moving forward with a major revision to the current Ontario code of safe practice that when complete will be available for use across Can-ada. The recent revisions to the use of ladder cages in Alberta and the issue of Mast Climbing training in Nova Scotia confirms the need to have consis-tent legislation with respect to the access and scaffold industry in Canada.

It has been a very busy time for the SIAC and much remains to be achieved however with your ongoing support we will contin-ue to be proactive for the access and scaffold industry in Canada.

ALUMA’S 35 YEARS OF EXCELLENCE &INNOVATIONThrough its unique blend of innovation and entrepreneurialspirit, Aluma Systems has made significant contributions toboth the construction and industrial markets. Aluma Systemstook root in 1972, when a young engineering crew tried tokeep production costs down and profits up in the face of risinglabour wages. The result was the Aluma Beam - a break-through in construction engineering that revolutionized theindustry by introducing high grade aluminum forming andshoring components to replace the expensive and heavy steelequipment that was previously used. The realized laboursavings for this innovation were up to 50%. To this day, itremains the industry benchmark.

Key Milestones and Achievements:

1972-1974: Joint Venture - Aluma Systems started in 1972, asa joint venture between Tridel and Alcan. In 1974, Alcan’sshares were purchased by Aluma Systems in 1974, allowingAluma to acquire full ownership.

1976-77: International Growth - Aluma grows rapidly intointernational markets with export sales to Venezuela andNorway.

1979-1980: Waco Acquisition - Aluma gains a major steelshoring and scaffolding rental fleet and a strong U.S. presencewith the purchase of Chicago-based Waco Scaffolding andShoring. The following year, Aluma pools the assets of threeconstruction supply companies under the Umacs of CanadaInc. umbrella. The Umacs acquisition allows Aluma to expandacross Canada, offering unparalleled support to light andheavy construction sites in every region.

1981-1985: Global Expansion - Aluma Systems continues togrow through joint ventures, distributorships and marketingoffices in Japan, Europe, the U.K., South America, SoutheastAsia and the Middle East. Aluma offered unique constructiontechnologies around the world.

1986 -1987: Burke Acquisition - Aluma Systems becomes afull-service concrete supply company with North America’slargest and most comprehensive inventory of forming,shoring, scaffolding and accessories. Through the acquisitionof the California-based Burke Company, Aluma Systems addshandset and craneset systems to its fleet, broadening thecompany’s product base, inventory and concrete constructioncapabilities. That same year, GKN Kwikform’s six U.S.locations were purchased and consolidated into theorganization.

1989: Anthes Acquisition - The company’s rental fleetexpands further with the purchase of the ConstructionEquipment Division of Anthes Industries Inc., adding 14Canadian and two U.S. locations. Aluma Systems embarks onits first Soviet joint venture in Moscow.

1990-91: International Joint Ventures - Aluma Systemsmoves into new markets in Europe, Asia and the Middle East.A second joint venture is established in Moscow to marketconstruction accessories, chemicals and other materials.

1994: Name Change - Aluma re-focuses on core business-shoring, formwork and scaffolding, at the same timeconsolidation the corporate image by changing the name ofThe Burke Company and Umacs of Canada inc. to AlumaSystems USA Inc. and Aluma Systems Canada Inc. Sameyear, Aluma’s won its first major contract in the oil sandsincluded material supply at the Syncrude plant, which waslater expanded to include labor. Shortly thereafter, materialsupply at Suncor was awarded to Aluma.

1999: Expansion in Oil Sands: Aluma wins two of thebiggest projects in the Oil Sands: the Upgrader project atSyncrude (UE-1), and the Millennium project at Suncor.These coupled with the addition of a third key maintenancecontract at Albian Sands, made Aluma the largest providerof Scaffolding servicesin the region.

2005: Aluma Acquisition - Brand acquires Aluma Systemsassets. The Aluma acquisition into the Brand family solidifiedthe company’s position as the North American SpecialtyServices leader and Aluma Systems has played a huge part inBrand’s rapid growth ever since. At the same time, Aluma’sConcrete Construction business received the largest capitalinvestment since the eighties. Additionally, since the Alumaacquisition, the company has made other significantacquisitions adding to the total service offering which willallow Brand to move considerably up the value chain. Brandand Aluma are truly better together, by sharing core valuesand consistently high standards of safety, integrity andcustomer service.

2007: Aluma acquires Doug Chalmers Construction Ltd(“DCCL”) of Sarnia, ON. The DCCL business is a criticalvalue-added supplier of scaffolding and civil constructionservices in Sarnia, a very significant Canadian industrialmarket. The synergies offered by the combination of the twocompanies will create a stronger, more competitive combinedorganization that provides better services to collectivecustomers and aligns the company with the many growthopportunities.

Legal Issues

Imagine a worker commencing work for an employer on tube and clamp scaffold-

ing falling ten feet to his death. The supplier erecting the scaffolding failed to secure guard-rails. The employer and supplier and their su-pervisors are charged under OH&S legislation.

Or imagine that workers and supervisors at a construction project under high voltage power lines fail to cover the lines as required before completing scaffold erection. While putting on the top rail using a forklift, the rail contacts power lines and the worker is tragically in-jured. This site owner is charged as construc-tor/prime contractor, and the employer and its supervisor are charged under OH&S legislation.

Lastly, imagine a suspended work platform purchased from a supplier being installed im-properly and collapsing, fatally injuring multi-ple workers. The com-pany, its engineers and supervisors, as well as officers and directors are all charged under OH&S legislation.

The facts of these scenarios have been changed slightly from real cases. But all are real and unfortunately typical trag-ic Canadian cases which resulted in pros-ecution or penalties to site owners, suppli-ers, or employers and their representatives.

WhyWorry?The Canadian OH&S environment has, for years, involved astoundingly high corporate and individual penalties and negative public-ity for OHS violators. Corporate sentences in the hundreds of thousands of dollars have often been imposed. Supervisors, manag-ers and workers have been fined and jailed. What Can We Do? Due Diligence in Practice In every tragic workplace accident, OH&S in-vestigators, prosecutors and courts are involved in assessing the same issues: what went wrong and did the corporation or the individual take the necessary reasonable steps in advance of the trag-edy to prevent it? The concept of taking advance

Detailed Written Policies and ProceduresCourt expectations regarding specific proce-dures are illustrated by the following case, R. v. Royal Homes Limited (January 16, 1987), On-tario Unreported decision, Wellington County, Payne, J. It is not an access-related case, but the principles apply. A truck driver was fatally in-jured when his load slid off the vehicle. He was underneath the vehicle attempting to adjust a steel cable that secured the load. The employer had no procedures in place to deal with this mat-ter and faced an OH&S prosecution for failing to “take every precaution reasonable in the circum-stances”. The court convicted, indicating that the employer was obligated to have detailed poli-cies and procedures that should have included:

routine inspection of every load prior to departure by supervisors;a comprehensive company policy for dealing with mechanical emergencies on route; an enforced policy of directing employees to refrain from placing themselves under any load; and regular and ongoing instruction and rein-forcement of safety procedures by super-visors

Detailed policies and procedures must be de-veloped to tell workers how to perform tasks

and deal with work-place hazards which have been identi-fied. They should take into account all OH&S obligations, including recognized industry Standards and general obliga-tions to “take every reasonable precau-

tion in the circumstances”. They should be understandable (organized, clear and written using a vocabulary that will be understandable to your workers). They should include detailed procedural instructions and safety “do’s” and “don’ts”. They must be kept up to date. They must be available to those expected to com-ply with them, i.e. handed out at training or pre-jobmeetings or safety meetings (not hid-den in a back office). Would your procedures meet these standards if a government enforcer attended after a serious workplace accident? Instruction and Training Well written and detailed procedures will not provide a due diligence defence if instruction and training in them is not conducted on an ongoing basis. It is not enough to claim that workers are generally well informed or expe-rienced in regard to safety. It will not be suf-ficient for a corporation or supervisor to hand

reasonable steps and action is well known as theconcept of due diligence, and the most com-mon legal defence relied upon in OH&S cases.

Due diligence as a defence to charges is one important perspective from which to under-stand the concept, but due diligence is much more than a defence. It provides a standard against which employers can judge the quality of their OH&S programs on an ongoing basis. “Due diligence” or “reasonable care” is a mat-ter discussed in long-established caselaw, and has been described as a matter of assessing whether “all the care which a reasonable (per-son) might have been expected to take in all the circumstances to avoid the circumstances which cause the accident”. But how do courts examine whether an accused party was “duly diligent” or took “reasonable care”. The legal standard is well-established, but what does it mean?

Here are some practical steps (and a few illustra-tive court comments) to help your business meet these standards to prevent workplace tragedies, OH&S penalties, and damage to your reputation.

Knowledge of OHSA Legal requirementsIt is fundamental that no party involved in a workplace tragedy, or charged under OH&S legislation, can argue, “We had no idea the law required that!” Implementation of due

diligence in the workplace requires a de-tailed understanding of all statutory obliga-tions which apply to the particular workplace.

OH&S legislation is structured so that it pro-vides direction on the general duties and re-sponsibilities required of workplace parties, and then specific provisions for workplaces or work activities in Regulations. All general du-ties in OH&S legislation, all applicable regula-tory requirements, all personal protective equip-ment requirements, all requirements relating to equipment, machinery and devices used at the workplace must be known. Do your supervisors know and have a copy of all current regulatory requirements? Your senior managers? Do they know and apply Standards establishing precau-tions applicable to the industry and workplace? Would anyone from your company say, after a serious accident, that they did not know the legal requirements and applicable Standards?

“The company, its engineers and supervisors,as well as officers and directors are all charged

under OH&S legislation.”

Legal Issues

out policies or reminders from time to time, with-out more instruction. Any effective system must provide for appropriate instruction and training.

An employer cannot just assume that academi-cally qualified workers (engineering students for example) are properly trained or leave training to a “wise old head” co-worker, who may not have been properly trained themselves. In R. v. Corporation of the Town of Napanee (1990) 8 C.O.H.S.C. 121 (Ont. Prov. Ct.), involving a confined space fatality, the court stated that to avoid liability, the corporation and supervisors should have en-sured that there was adequate equipment, detailed instruction and appro-priate demonstration of proper use of equip-ment and the proper procedures to follow, and supervisory follow-up to ensure that train-ing was understood and actually being put into practice in the confined space entries.

Hiring supervisors who have experience in the particular activity without taking steps to ensure proper instruction or training in re-gard to specific hazards will also not be suf-ficient. In Helmer Pederson Construction, (February 1, 1990) Ont. Dist. Ct., Sudbury, S. D. Loukidelis, J. the court stated that “hiring a competent foreman or superintendent is not the end of a company’s responsibility”. Could your organization establish that workers and supervisors have detailed and ongoing train-ing and instruction, and safety reminders, in relevant procedures and requirements to ensure safety in performing all hazardous work tasks? Could you produce records to prove this? Supervision, Monitoring and EnforcementAn effective system which meets OH&S due diligence standards should also make it clear that supervisors bear an important respon-sibility to engage in ongoing monitoring to ensure that workers are “doing what they are supposed to do”. While safety is certainly the responsibility of each individual worker, through duties imposed on workers in the OHSA, government enforcers and the courts uniformly expect that supervisors and manag-ers will take the lead in supervising, monitor-ing, and ensuring safe work practices are fol-lowed. Supervisors must not assume that once an instruction is given, it will be complied with. Ongoing monitoring, supervision and follow-up is necessary to ensure compliance.

ence in R. v. Placer Dome (CLA) Ltd. (2002), 2002 CarswellOnt 5721 (Ont. Ct. of Justice) affirmed on appeal (2003), 2003 CarswellOnt 3211 (S.C.J.). One employee was killed and another injured when a tractor tire they were inflating blew up. There was no safety equip-ment used to protect them in the event of a tire blowing up. The manager instructed work-ers not to work on the equipment because it was for sale “as is.” However the manager

did not follow-up or make any inquiry after giving the instruction. He also failed to make any inquiry after receiving written notice in a weekly report that flat tires were being aired up.

The expectation of courts that systems be ef-fective also requires that all elements of the system that has been established, be enforced. In R. v. Wilson’s Truck Lines Limited (May 22, 1998) Ont. Ct. Justice, Toronto, McNish JP, [1998] O.J. No. 3219, the court, considering whether an employer had taken every reason-able precaution relating to procedures at a load-ing dock (a worker who was supposed to have a spotter but was working alone was crushed between a vehicle and a loading dock), stated: “The dock supervisor agreed that there were no written warnings, dismissals or suspensions for breach of safety procedures. He also never told any workers if they were on the ground with-out a spotter, that they would be disciplined.”

The court concluded that “there was no dis-cipline or action if any rules were breached ... the supervisor admitted that there was no written censure, no firings, demotions or sus-pensions. The atmosphere was very “laissez-faire”. The company was convicted because its system was not enforced and effective.

Would your organization be able to estab-lish to an enforcer or court (with documenta-tion) that supervisors regularly monitor the job site, or conduct documented job observations to confirm that procedures are understood and followed. Are there pre-job checks of equip-ment and access structures before work com-mences? Spot checks? Site Walks? Do you require your supervisors to do them while work is ongoing? Do they document their checks of the site using a checklist? Is there is increased

monitoring for high risk activities or after a near miss or report of non-compliance? Lastly but not least, have you ensured that supervisors and managers are trained in effective and proper disciplinary steps? Are they expected to monitor workers and enforce safety procedures as part of supervisory performance expectations? Attempting to create due diligence steps after an accident has occurred, or OH&S prosecution has

been commenced, is not an option. The OH&S duediligence fundamen-tals discussed above should be used as a guide for taking the necessary prac-tical steps to meet court-developed due diligence standards,

and for proper documented health and safety programs. Cheryl A. Edwards is a former Ontario Minis-try of Labour OH&S Prosecutor, now heading up the OH&S Practice Group of the Toronto management-side labour and employment firm Stringer Brisbin Humphrey, Manage-ment Lawyers.

Safety Talks - Suspended Access 27

Suspension systems on swingstages, work cages, andbosun’s chairs can fail. If you are not using a fallarrest system, you can fall, su�ering injury or death.

Fall-Arrest Inspection

[This part of the talk should include hands-oninspection of equipment.]

Fall-arrest equipment is your last line of defence.Make sure it works.

Your harnessmust have a label identifying the CSA(Canadian Standards Association) standard towhich it complies.

Check the harness for

• cuts, burns, and signs of chemical damage

• loose or broken stitching

• frayed web material

• D-ring and keeper padsshowing signs of distortion,damage, or undue wear

• grommets and buckles showingdamage, distortion, and sharpedges

The lanyard must be securelyattached to the harness D-ring bya locking snaphook or otherapproved means.

Your lanyard andshock-absorbermust be free of fraying, kinking,and loose or broken threads. The

hardware should not be deformed, rusty, cracked,or unduly worn. All moving parts must move freelyand easily through their full range of movement.

Make sure yourrope grab is working, matches thetype of lifeline you are using, and has no damagedparts or sharp edges that could cut the lifeline.

Your lanyard must be attached to the rope grabwith a locking snaphook to keep it fromaccidentally coming out.

Your lifeline should be free of damage, wear, anddecay. It must be protected from rubbing andscraping where it passes over corners or edges.

Explain dangers

Identify controls

Demonstrate

The basic rule is simple: there must be twoindependent means of support for workers usingsuspended access equipment.

Two Independent Means of Support

One independent means of support for each workeris the suspension systemholding up the stage,cage, or chair.

The second independent means ofsupport is thefall-arrest system .This consists of• full body safety harness

• lanyard

• rope grab

• lifeline

• lifeline anchor.

If the suspension system fails, theworker will be saved by the fall-arrest system.

In some cases, the secondindependent means of support can be anothercomplete suspension system. On a swingstage, forinstance, there would be four outrigger beamsinstead of two, four suspension lines instead of two,and so on. If one suspension system fails, the otherwill take over. This arrangement is used on a tieredstage.

But even with two complete suspension systemsyou must still wear a full body harness and lanyard.In this case you would tie o� to a stirrup on thestage or to a line secured to both stirrups.

Tiebacks

Tiebacks are used to secure the outriggers andcounterweights of suspended access equipment.The tieback holds the major components of thesuspension system together. It keeps them frombeing loosened or dislodged and secures themback to an adequate anchor point.

Let’s follow a wire ropetieback from start to �nish.

The tieback runs fromthe thimble of thesuspension lineback along theoutrigger beamwith at least onehalf-hitch oneach section.

Then itloopsaroundthe counterweight handles and extends backto adequate anchorage.

Now let’s see how each part is connected.

1. We secure the wire rope tieback to the thimbleof the suspension line with cable clips.

2. We make a half-hitch through the handle oneach section of the outrigger beam. Even if thebeam doesn’t have handles, we still use the half-hitches.

3. We run the tieback through and then backaround the counterweight handles.

4. We attach the tieback to the anchor, again withcable clips. We make sure the tieback is taut.

What’s an adequate anchor?

• engineered tieback systems such as eye boltsand rings as identi�ed on an approved roof plan

• the base of large HVAC units

• columns on intermediate building �oors or stubcolumns on roofs

• large pipe anchorage systems (12-inch diameteror bigger)

• roof structures such as mechanical rooms

• parapet clamps attached to reinforced concreteparapet wallson the other side of the building

• If unsure, workers and supervisors must askfor assistance in �nding an adequate anchor.

Suspended access equipment can fail if you don’t set up allthe components properly, including tiebacks. Improper set-up can lead to injury or death from a fall.

Without the right number of counterweights,suspended access equipment can fail, leading toinjury or death.

This means that the e�ect of the counterweightsholding the equipment up must be at least 4 timesgreater than the load pulling the equipment down.

Another way of saying this is that...

• the distance of the outrigger beam from thefulcrum to the centre of the counterweights (Y)...

• multiplied by the load of the counterweights...

• must be at least 4 times greater...

• than the distance of the outrigger beam from thefulcrum to the suspension line (X)...

• multiplied by the capacity of the climber.

Let’s look at an example.

Explain dangers

Identify controls

Demonstrate

Here’s how to calculate the number ofcounterweights you need.

Let’s start with the design factor. For beams andweights the design factor must be 4 to 1.

Go over this example with your crew.

The beam is 18 feet long. The counterweights will require at least 2 feet of space at the end of the beam.There is a 1-foot overhang and a supported load of 1000 lb.

X = 1 ft. Climber load = 1000 lb. Therefore 1ft. x 1000 lb. = 1000 ft. lb. pulling down.

The resisting force, including the design factor of 4 thatmust be provided by the counterweights = 4 x 1000 ft. lb. = 4000 ft. lb.

Y = 18 ft. – 1 ft. (overhang) – 1 ft. (centre of weights) = 16 ft.

The load required by the counterweights = 4000 ft. lb. = 250 lb.16 ft.

Assuming counterweights are 55 lb. each, number of weights required = 250 lb. = 5 counterweights55lb.

If labels on an outrigger beam are missing or not readable, do not use the beam.

Remember—only use counterweights that have been speci�cally manufactured for the particular outriggerbeam you are using.

Hydro Mobile - Project ProfileBy Frank Defrasne [email protected]

An ingenious contractor with a versatile equipmentLast year, the Maritime Institute of Quebec de-

cided to have its facade renovated in Rimouski, Cana-da. The bricks covering the six-story building had be-come unstable and needed to be demolished and replaced. Among the many bidding companies was DRM Constructions, a general contractor based in Rimouski. “For demolition jobs, we usually work with scissor-lifts and pneumatic drills, and this is what first came to my mind”, explains Mr. Morin, General Direc-tor at DRM. “We also punctually use a mini-excavator equipped with a hydraulic hammer. It is very powerful and productive, but the articulated arm can only reach 10’ high, which was not enough to cover the six stories of the Institute. I then remembered Hydro Mobile’s mast climbing work platforms, access equip-ment I had used about ten years ago on a construction project. I started to wonder if I could use this technology to lift the mini-excavator to the desired height”, continues the General Director.Following this reflection, Mr. Morin decided to contact Nel-son Panneton of Du-For Scaffolding, one of Hydro Mobile’s re-gional distributors. Together, they sat down to evaluate the fea-sibility of the idea and came to the conclusion that the Hydro Mobile’s M-Series would be perfect for the job. Mr. Panneton explains: “Several models on the market have high load capaci-ties, but they require that the weight be distributed evenly. The M-Series has a 20,000 lb capacity and is the only point-load mast climber in its range. Therefore, it could support the weight of the mini-excavator, even with the resonance factor. More-over, the M-Series’ decks are 7’ wide, except around the masts were they are 44” wide, just enough for the 40”-wide excavator.”Mr. Panneton and Mr. Morin simply had to modify the brack-ets linking the platforms together so that the mini-excavator could travel along the 230’-long facade. For more stability, the mast-climber also had to be tied every 10’ instead of the usual 20’.When this innovative solution was presented, the Maritime In-stitute gave the contract to DRM Constructions without hesitat-ing. “Using this method, the schedule was one week per floor with five workers, while it would have taken one month per floor with seven men using scissor-lifts”, explains Mr. Morin. “Moreover, pneumatic drills cause fatigue and injuries, while the mini-excavator and the hydraulic hammer never get tired!” The Maritime Institute plans to have the other part of its facade renovated next year and DRM Constructions will most certainly bid for that contract too. Dany Morin con-cludes: “Now that the competition knows our method, we will have to be imaginative and innovate once more”.

Scaffold Training Goes High Tech Call it a sign of the times. Call it evolution. Call it what you wish, training and development in the scaffolding industry has met the 21st century, through

online training. Powered by Hightek, an SIA Accredited Training Institute, scaffoldinspection.com is now offering an online, blended learning training program for the inspection of supported scaffolds. The program features the traditional program manual workbook, but the learning process is blended with online eLearning modules and scaffold inspection simulations. The program is finally completed with a live one-on-one scaffold inspection coaching session with a Hightek instructor and an online written test. “The blended learning program gives us the best of all worlds” states Stephen Pike, Lead Instructor for Hightek, “between the workbook, eLearning modules and the simulations we are able to tap into all three learning styles for the adult learner. The simulations and coaching sessions provide a great opportunity for the trainee to practice and demonstrate their skills in a safe and interactive environment.” Using special software, the simulations are based on typical “real world” supported scaffolds in frame, system and/or tube & coupler scaffold structures. The simulations provide typical data on the scaffold type, purpose, design, construction and condition for the scaffold inspector trainee to evaluate and make their determination. In a recent survey, conducted by Hightek for this training program, the Top 5 most preferred features of the Supported Scaffold Inspector Training course are: *Learn anytime - 24/7 accessibility *Scaffold Inspection Simulations *One-on-one coaching/more interactivity *Ability to ask questions directly with instructor *Multiple learning methods (workbook, eLearning, simulations, etc.) Most of our scaffold inspector trainees are busy people. They need a program that is flexible in terms of schedule and can allow them to learn at their own pace, site and schedule. “World is the first ‘w’ of ‘www’” adds Pike, “We have scaffold inspection trainees who are now learning from sites all across Canada and the United States, as well as on four other continents around the world.” For more information, Hightek’s Supported Scaffold Inspection training program can be found at: www.scaffoldinspection.com

Suspended Elevating Platforms

Typical Suspended Elevating Platform

Supporting Structure

By Ralph Balbaa, P. Eng. [email protected]

In designing and constructing suspended elevating platforms and supporting structures, good engineering practice and the following Regulations and Standards and Codes must be adhered to:

• TheOccupationalHealthandSafetyActand Regulationsforconstructionprojects213/91as amended. • CSAZ271-98“SafetyCodeforSuspendedElevat- ingPlatforms”

• CSAW59.2-M1991“WeldedAluminumConstruc- tion. • CSAW59.1“WeldedSteelConstruction” • CSAS16-01“LimitStatesDesignofSteelStruc - tures” • CAN3-CSAS157-M83“StrengthDesigninAlum- inum” • OntarioBuildingCode

The designer must consider the capacity of the powered hoists as well as the rated load and dead load of the platform and components, supporting structure components and rigging components and hardware.

Data indicates that accidents have occurred when the platform becomes “snagged” on a projection on the building façade and the hoists operated until their overload protection device is triggered.

There is a range of hoist capacities. The common hoists used on suspended stages has a rated load of 1000 Lbs. (455 Kgs.) and hoists must be supplied with overload protection switches designed to trigger when the tension in the wire rope ex-ceeds 125% of the rated load of the platform.

Different lengths of stages are sometimes required to access a building facade that makes modular staging a practical solution. The knocked down modular stages utilize different length sections that connect together to provide the required length. Corner and circular sections are also available.

When designing a support structure, ergonomics must be considered. For example, designing and supplying a heavy davit arm (over 150 lbs.) that is difficult to handle by two workers should be avoided. Davit arms and other heavy transportable members may be designed in sections that are connected on site.

rigging equipment that is assembled or moved within 2 meters of a fall hazard must be tied back during erection and transport.

Suspended elevating platforms used to access a façade that is more than 45 meters ((150’) must be stabilized to the building to avoid ex-cessive sway. This is accomplished in a variety of ways some of which include vertical tracks or individual “buttons” in the building façade.

Modular Staging

Suspended Elevating Platforms

24

By Ralph Balbaa, P. Eng. [email protected]

When in service, suspended elevating platforms, their rigging and supporting structure must be inspected by a qualified person daily and tested as frequently as is necessary to provide proper main-tenance. Special attention must be given to wire ropes, as they are the cause of a variety of accidents and mishaps on sites.

The supporting system and permanent equipment must also be inspected at least annually by or under the direction of a professional engineer.

It is important for an employer to ensure that all workers operating or using a suspended elevating platform are competent and are fully trained in its use. Training, at a minimum is to include controls, winches, proper rigging and rigging component safety, wire rope inspection, tieback and fall arrest equipment and use.

Each employer is required to prepare a rescue plan that is put in effect in the event of an accident occurs. All workers on the project must be trained to implement the plan in the event of a mishap.

A unique application for the Versa™ steel systems was implemented in the design of MCM’s 2001 Inc. scaffold

work station for Toyota in association with Bartlett & As-sociates of Toronto. The design has been nominated for the people’s choice awards Best of Canada Design Competition.

The scaffold structure was comprised of standard Versa™ systems scaffold components such as the rosette, ledger mouth piece along with the standard size tube used for sys-tems scaffolding. In order to meet the design criteria Mills worked with existing drawings provided by MCM to manu-facture a complete modular system to suit their clients’ needs. The custom made ledgers and standards were then zinc plated as opposed to the traditionally used method of galva-nizing to give the finished product an esthetic finish more in common with office type furniture.

The end result was a rugged modular work station that sur-passed the customers’ needs in fit and finish as well as form and function.

Contractors and scaffold suppliers may not be aware of new requirements for the design and use of multi point sus-pended scaffolds and the impact on their company and scaffold products.

Ontario Regulations for Construction Projects were amended on October 1, 2004 to include a series of comprehensive requirements for the design, construction, and inspection of multi point suspended scaffolds and platforms.

Multi point suspended scaffolds are used extensively in the access industry to provide a safe and convenient working sur-face for a wide range of applications on construction projects and industrial workplaces. They range from large area multi tiered platforms commonly used for bridge repair and restoration work to small four point scaffolds used for inspection activities and light duty applications.

The definition of a multi point sus-pended scaffold (MPSS) has been expanded to include a relatively broad range of suspended scaffolds and plat-forms used throughout the industry. An MPSS is now defined in Ontario Regulation 213/91 as any suspended scaffold or platform more than 750mm wide (29.5 inches) where three or more suspension points are required for stability.

These requirements are broad and far reaching and many designers, employers and suppliers may not be aware of the implications to their scaffolding products.

The regulations cover a wide range of topics including: Minimumplatformloading Designbyaprofessionalengineer Redundantsuspensionsystem Approvalbythepermanentstructureengineer Engineeringdrawings Siteinspectionsincludingsignoffreportbyaprofessionalengineer Erectortrainingandtrainingforusers Specificrequirementsforusingpersonalfallarrestsystems.

Key regulation Highlights

Design LoadsThe MPSS, including all of the components, must be designed by a professional engineer to meet the specific loading criteria set out in the regulation. Depending on the application, a minimum uniformly distributed live load of 25, 50, or 75 lbs. per square foot is required as well as wind loading and other specified loading effects. The loads during erection, dis-mantling, and traversing must also be determined by the design engineer. Designers must be aware of the design criteria set out in the Regulations for Construction Projects.


NOVEMBER 2007 28

By Jim Wilkinson, P.Eng. [email protected]


Approval by Permanent Structure EngineerThe regulation sets out a specific duty of the constructor of the project to obtain the written approval by the permanent structure engineer for the reaction forces from the MPSS on the perma-nent structure. It is highly recommended that the supplier and constructor advise the building or structure owner of this require-ment prior to finalizing any contractual agreements. The reaction forces should be specified on the design drawings. Suspension redundancyMany contractors and suppliers have asked questions regarding the redundancy requirements for the platform suspension sys-tem. This requirement means that the suspension system must be designed and installed such that, if a suspender or one of its components fails, the remaining suspension system will continue to support the platform with no reduction of the original safety factors. Practically, this is accomplished by double suspension systems or multiple suspenders located throughout the platform.

Drawing requirementsThe regulation sets out very prescriptive requirements for the amount of information to be included on the engineering drawings. For example, detailed procedures for erecting and dismantling, the wind speed at which work should stop, reaction forces on the building and assumed loading conditions must be indicated on the drawings. Site Inspections The MPSS must be inspected by a professional engineer after the final installation and before being used by the trades. The professional engineer must provide a “positive report” indicating that the installation complies with the design drawings and all the components are in adequate condition. The report by a professional engineer is not required if the plat-form area is less than six square meters however daily inspec-tions by a competent worker must be carried out and document-ed. Erector and user TrainingIn addition to the normal erector training, the employer must provide all workers on the scaffold oral and written instructions on its safe use. The training must include manufacturers instructions, load limitations and most importantly the circumstances for using personal fall arrest systems.

To assist the industry the Ministry of Labour has published a guideline for multi point suspended scaffolds which de-scribes very specific responsibilities and duties of constructors and employers when a multi point suspended scaffold is used on a construction project. Copies of the regulations and guideline are available online at the Ontario Ministry of Labour website. For more information visit, www.labour.gov.on.ca Photographs courtesy of Winsafe Corporation

Code of Safe Practice

29

Suspended Powered Scaffold; Ontario

The following are some common sense rules designed to promote safety in the construction of scaffolding. These guidelines do not purport to be all-inclusive or replace other additional safety and precautionary measures. They are not

intended to supersede the requirements of any provincial regulations, codes and ordinances. The user shall be responsible to comply with all recognised provisions.Where possible, post the Code of Safe Practice in a conspicuous place and ensure that all persons who erect, dis-mantle or use scaffolding are aware of these. It is recommended that these instructions are the subject of tool box meetings.GENErAL GuIDELINES: 1. If in doubt regarding safety or use of suspended scaffold, consult your scaffold supplier. 2. Follow all equipment manufacturers’ recommendations as well as all local, provincial and federal codes, ordinances and regulations, pertaining to suspended scaffolding. 3. Survey the job site for hazards such as exposed electrical wires, obstructions that could overload or tip the suspended scaffold when it is raised or lowered, unguarded roof edges or openings inadequate or missing tieback anchorages, or the need for overhead protection where exposure to falling objects exist. These conditions must be corrected before installing or using suspended scaffold systems. 4. Inspect all equipment before each use. Never use any equipment that is damaged or defective in any way. Tag damaged or defective equipment and remove it from the job site. 5. Always use fall arrest equipment when using suspended scaffolds. See the Fall Arrest Equipment Guide line section for further reference. 6. Erect, use and dismantle suspended powered scaffold equipment in accordance with design and/or manufacturers recommendations. 7. Do not erect, dismantle, or alter suspended scaffold systems unless under the supervision of a qualified person. 8. Do not abuse, misuse, or use suspended scaffold equipment for purposes or in way for which it was not intended. 9. Users must be trained on how to safely operate equipment and how to handle emergency situations, if in doubt, consult a qualified person. 10. Erected suspended scaffolds should be continuously inspected by the users to ensure that they are mainly trained in a safe condition. Report any unsafe condition to your supervisor. 11. Care must be taken when operating and storing equipment during windy conditions. 12. Powered platforms must never be operated near live power lines unless proper precautions are taken. Consult the power service company for advise. 13. Do not work on scaffolds if you feel dizzy, unsteady in any way or are impaired in any way by drugs or any other substance.rIGGING GuIDELINES 1. When rigging on exposed roofs or floors wear fall prevention equipment. When rigging from overhead supports, such as bridges, beams etc. wear fall arrest equipment. 2. Roof anchorages, parapet clamps, outrigger beams, or other supporting devices, including tiebacks and their anchorages, must be capable of supporting the rated load of the hoist with a safety factor of four (4). 3. Verify that the building or structure will support the suspended loads with a safety factor of at least four (4). 4. Overhead rigging, including counterweights, must be secured from unintentional movement in any direction. 5. Counterweights used with outrigger beams must be of a non-flowable material and fastened to the beam. 6. Outrigger beams that do not use counterweights must be installed and secured on the roof structure with devices specifically designed for that purpose. 7. Tie back all transportable rigging devices with wire rope and hardware that has strength equal to the hoist rope. 8. Install tiebacks at right angles to the face of the building and secure without slack to a structurally sound portion of the structure. In the event tiebacks can not be installed at right angles, use two tiebacks at op- posing angles to prevent movement. 9. Rig so that suspension points are directly above the hoisting machines. 10. The platform must be secured to prevent swaying. Do not tie it to window cleaning anchors.

WIrE rOPE AND HArDWArE GuIDELINES 1. Use only wire rope and attachments as specified by the hoisting machine manufacturer. Do not use wire rope that is kinked, birdcaged, corroded, undersized, or damaged in any way. 2. Be sure that wire rope is long enough to reach to the lowest possible landing. 3. Clean, lubricate and handle wire rope in accordance with the wire rope or hoist manufacturer’s instructions. 4. Coil and uncoil wire rope in accordance with the wire rope or hoist manufacturer’s instructions in order to avoid kinks and damage. 5. Use thimbles at all wire rope suspension terminations. 6. Use J-type clamps or swaged fittings to fasten wire ropes. Do not use U-Clamps. 7. Tighten wire rope clamps in accordance with the clamp manufacturer. 8. Wire ropes used with traction hoists must have prepared ends in accordance with the manufacturers recommendations. 9. Inspect wire rope during each ascent and decent. Do not expose wire rope to fire, undue heat, corrosive atmosphere, chemicals, or to passage of electrical currents or to damage by tools or handling.POWEr SuPPLy GuIDELINES 1. Be sure your power supply conforms to hoist manufacturer’s recommendations. 2. Ground all electrical power sources, power cord connections and protect with circuit breakers. 3. Use power cords or air hoses of proper size that are long enough for the job. 4. Power cord or air hose connections must be restrained to prevent their separation. 5. Tie off power cords or air hose to the suspended scaffold to prevent them from falling. 6. Protect power cords or air hoses at sharp edges. 7. Remember, air hoists require clean, lubricated air.FALL ArrEST EQuIPMENT GuIDELINES 1. Each person on a suspended powered scaffold must be attached to a fall arrest system at all times. 2. Each lifeline must be fastened to a separate anchorage. 3. When wrapping lifelines around structural members the lines must be protected and a suitable anchorage system must be used. 4. Protect lifelines at sharp corners to prevent chafing 5. Rig fall arrest systems to prevent free fall in excess of six feet. 6. Lifelines must be suspended freely without contact with structural members or building façade. 7. Use a lifeline size and construction that is compatible with fall arrester and complies with applicable safety codes. 8. Be sure fall arrester is installed on the lifeline in the proper direction above your head and in accordance with the manufactures’ recommendations. 9. Use a body support device that is properly sized and fitted. 10. Be sure body support device has lanyard attached to the D-ring at the center of the back.SOME ADDITIONAL GuIDELINES 1. Use all equipment and all devices in accordance with the manufacturers instructions. 2. Do not overload, modify, or substitute equipment. 3. Before commencing work operations pre-load wire rope and equipment with the maximum working load, then retighten rigging clamps to manufacturers’ recommendations. 4. Be sure platform and cages have a proper guardrail system. 5. Secure stirrups no less than six (6) inches from the end of the platform. 6. All components must be securely fastened to prevent them from falling off the platform. 7. Use roller bumpers or buffers to prevent damage to the structure or equipment. 8. Use care to prevent damage to equipment by corrosive or other damaging substances. 9. Clean and service equipment regularly. 10. Always maintain at least four (4) wraps of wire rope on drum type hoists. 11. Traction hoists must have wire rope that is long enough to reach from the highest point of support to the lowest possible landing, plus reefing lengths. 12. Do not join platforms unless the installation was designed for that purpose. 13. Do not move suspended scaffolds horizontally when occupied 14. When re-rigging for another drop, be sure sufficient wire rope is available before moving the suspended scaffold system horizontally. 15. When welding from suspended scaffolds: a. Be sure platform is grounded to structure b. Insulate wire rope above and below the platform to protect from damage by the welding torch or electrode. c. Insulate wire rope at suspension point and be sure wire rope does not contact structure along its entire length.NOTE: you must refer to the General Guidelines for additional information relating to this product group.
