Mobile & Fixed Plant / HVAC Filtration Systems- Background
q Filtration Panels / Cartridges of conventional Systems are not adequately sealed or / & do not use HEPA Grade Filter Media & so will not provide ALARA or compliancy to OEL Legislation.
q Most Pressurisers are provided for External Air & not for Recirculation Air (Panel Media is non- compliant).
q Mobile / Fixed Plant Cabins are subjected to "dusty" contaminated operating environments- eg Mining, Quarrying, Construction, Earthmoving, Fertiliser, Cement, Agriculture, Timber & many others.
q These environments contain airborne particulate / fibres that can cause severe lung disease & other short & long term health issues.

Mobile & Fixed Plant HVAC / Filtration Systems- Background
HVAC / Filtration costs to operations are extensive for:
q Frequent Filter Media replacement.
q Labour for Filter Element exchange.
q Electrical Equipment failure & replacement.
q Frequent & premature failure of HVAC
components ($10,000- $30,000 / annum /
machine).
q Associated loss of Production, etc.
q HVAC (Air- conditioning) Systems do not provide
adequate Cabin Filtration or Cabin
Pressurisation.
Internal Recirculation Panel Filter- blocked after only 50 hours.
“Chocked” / failed Evaporator Coil of HVAC
after 250 hours

OEL compliance is not just for RCS (Respirable Crystalline Silica)- but also other Particulate & Fibres that are Respirable such as asbestos, nickel, alumina, DPM (Diesel Particulate Matter), etc. The 2013- ISBN 978-1-74361-
055: Workplace Exposure Standards should be referenced to ascertain respective OEL limits.
q The current Australian SafeWork Standards ( legislates exposure limits: üFor RCS is < 0.1 mg / m3 Air Breathed TWA (Time Weighted Average) for a 8 hour shift. üAsbestos 0.1 Fibre / ml & L/ W ratio of 3:1, DPM as for RCS- MDG29- not published). üA 12 hour shift using the Brief & Scala adjusted calculation, RCS OEL < 0.05 mg/ M3
(TWA). üTesting is to be recorded / completed frequently- MSHA (USA) have implemented CPM
(Continuous Particulate Monitoring) for Coal Mines.
Safework- Workplace Particulate & Fibre- OEL Compliance
q To achieve Compliance: üAll Respirable Particulate >0.3u be removed @ 99.97% arrestance (AS 4260-1997). üIn the case of Fibre / DPM (carcinogens) exposure- HEPA Filter Media of >H13 / H14

Other aspects of Compliance, OH&S issues that need to be considered are: q CO2 Concentration: (AIRAH: 700- 1,000 ppm limits) drowsiness, loss of concentration,
fatigue, micro- sleeps, acidosis.
q Exhaust Air Flows: Fresh Air (Exhaust Air) Flow is required to off- set Co2- AIRAH 10-15 l / seconds (20-30 Cfm) / Occupant.
q Optimising Operator Thermal conditions: Avoids Fatigue & Micro- sleeps, enhances Productivity.
q Rapid Filtration of Recirculation Air: Entrapped Contamination enters via Operators clothing / boots, opening of doors / windows, etc (20-30 / hour Volume of Cabin).
Cabin Pressurisation:
q There is no Australian Standard for minimum / maximum Cabin Pressurisation.
q NIOSH1 states “reasonable range” 20-60 pascal (although tests have shown that at 60 kph=
external Wind pressure of 100 pascal).
q EN474-1:2014-03- Earthmoving Machinery Safety- Part 1 states 50 pascal.
q LSM suggest >80 pascal with optimum between 120-150 pascal / 200 maximum. NIOSH1 Source: H&S Workshop Key Cab Factors NIOSH Presentation 2013

How Important is Co2 Concentration?
[QCEA System must never be designed to allow 100% Recirculation Air otherwise Co2 Concentration, Under- Pressurisation & Contamination of Cabin.
[ It is best practice that the QCEA System is never turned off when occupied so as to ensure that there is a continuous flow of "blended" fresh / external air, at all times.
[An In- Cabin Sensor Warning Unit should be used to monitor Cabin Pressurisation (Filter Loading / Air Flow) to ensure Fresh Air / Positive Cabin Air is supplied at all times.
Simulate Blocked Filter- Recirculation Air Only
Cabin De- pressurised
Co2 > 4,000 ppm in 25 minutes. Max allowable is TWA 1,000

How Important is: Co2 Concentration?
[Video we demonstrate how Co2 levels can concentrate quickly from the respiration of the occupants inside the Cabin.
[Unacceptable Co2 concentration (> 700- 1,000 ppm) has proven to effect Concentration, cause Fatigue / Micro- sleeps, etc & in severe cases Acidosis.
[AIHRA recommend "Exhaust Air Leakage"- Fresh Air displacement- 10- 15 litres / second for each Occupant inside a Cabin.
[More Occupants- eg Light Vehicles / Buses require increased External Air Flow to off- set Co2.
(22)

[ It would be reasonable to presume that if Phil was working normally the his respiratory rate would be higher with Co2 concentration being even more excessive and increasing more quickly.

How Important is: Cabin Pressurisation / External Air Filtration
[Video demonstrates efficiency of QCEA System excludes Contamination entering the Cabin- filtering External Air to HEPA >H13 / H14 levels of 99.995% @ 0.3 micron.
[ Inadequate (lower than external pressure) or Negative Cabin Pressure will allow contamination enter Cabin.
[Cabin pressure >80 pascal, optimum 120-150 pascal & maximum 200 Pascal.
[Over- pressure damages / permanently deforms Cabin Seals allowing ingress of Contamination when the Machine / QCEA System stopped.
[Cabin Over- pressure also risks discomfort to the Operator / damaging Ears.

How Important is: Recirculation Air Filtration
[Video demonstrates the efficiency of the QCEA System Recirculation Filtration Unit to remove Entrapped Airborne Contamination by filtering to HEPA >H13 / H14 levels of 99.995% @ 0.3 micron Contamination from within the Cabin.
[Phil creates Airborne Particulate Events by rubbing his clothing, moving his feet- even rubbing his skin / hair.
[Contaminants also become Airborne with Machine / Operator movement.
[ Larger events mass concentration levels were >3.0 mg / m3 smaller events <0.2 mg / m3 (OEL for RCS should be <0.05 mg / m3 TWA for a 12 hour days).

Filter Elements / Media- Explained (27)
LSM Technologies / Sy- klone RESPA CF / CFX Filter Elements are: q RESPA CF (External Air)- Ported Ejection Filter Element.
q RESPA CFX (Recirculation Air)- Non-Ported / Closed Element.
q Robust in construction & “fit- for purpose” for Mobile Plant.
q Service Life> 500- 1,000 hours.
q Ensure the correct Filter Element is in the correct RESPA Unit.
q Filter Elements should not be used >1,000 hours so as to avoid deterioration & entry of contamination into Cabin / HVAC Systems.
RESPA CFX Recirculation Air Filter Elements- note that this is Non- Ported
RESPA CF External Air Filter Elements- note that the black
end has Ejection Ports
Special Notes: [Filter Elements should not be “Washed” / Re- used.
[Always ensure that Supplier provides DOP Certification of the complete QCEA System by DOP Testing at >H13 / H14 class inside the Cabin- after installation of the System- do not accept supplier statement that their Filter Media or System is “HEPA”.
[DOP Testing is referred to as “Dispersed Oil Particulate Test” as per ISO / EN1822 Standard.

Cabin Pressurisation- Importance of a- In- Cabin Alarm Monitor (28)
LSM Technologies- Quality Cabin Environmental Air Systems- "Understanding the Essentials" - Copyright 2015
When to change a Filter Element:
q Use a In- Cabin Pressure Sensor to monitor the cabin
Pressurisation.
q Once Cabin Set- point Pressure is known then Alarm
Threshold should be between 20-40 pascal below the
achieved set- point.
q Alarms setting should signify Filter Element Exchange.
In- Cabin Pressure Sensor Alarm will:
q Alarm to signify a change in Cabin Pressure (below Alarm threshold).
q Change in Cabin Pressure will be cause due to Opening of Doors / Windows, Leaking Seals
but predominantly when Filter Element becomes loaded.
Note: It is essential that the Vehicle Alternator meets the requirements for power draw (at engine idle) of the QCEA System otherwise fluctuation in Cabin Pressure will occur with false alarming.

How it Works- RESPA(Tm) External Air Unit- Precleaning (30)
[Contaminated laden Air enters the Unit Inlet. [ 2. The Fan creates a VORTEX, a tornado-like
spinning motion, whipping the Air & Contaminant to the outside wall.
[ 3. Spinning Air HYPER-accelerates as it passes through Louvers, further enhancing centrifugal forces powerful enough to affect Contaminant Separation.
[ 4. Contaminant is spun against the outside wall of the Unit & propelled rapidly around the Filter to the rear of the Unit. 5. Contamination is ejected back into the environment via the Ejection Ports .
[ 6. Precleaned Air passes through the Filter & continues to the Outlet.
1. External Air Entry
2. Precleaner Ejects >97% Debris back into
Environment
3. Fresh Filtered Air to HEPA >H13 / H14 to
Cabin
q The External RESPA™ extends Filter Element Service Life by >10 due to its unique & patented Precleaning Technology

(38)
q Consider compliance requirements to Australia (& International Standards).
q Keep abreast of changes in SafeWork Exposure to Airborne Contaminants & WHS Standards as there is an intensified focus in Compliance & lowering of OEL / PEL.
q Conduct frequent OEL & PEL Sampling & good Records- for 30 years.
q Consider who is in the “Chain of Accountability” as a PCBU under WHS Act.
q HEPA Filter Media does not necessarily make a HEPA System- ensure that the complete System is DOP Certified to >H13 / H14 after Installation & meets subsequent testing between Filter Element replacement.
q Ensure that the QCEA System is designed “fit- for- purpose” considering not just Contaminant Exposure but all other OH&S parameters (Pressurisation, Co2 Exhaust, etc) / Operational / Machine conditions.
q Ensure that your QCEA System Supplier guarantees System Compliance.
q On- going management of implemented QCEA System Control Measures is critical to maintain Compliance.
q Include your QCEA System Supplier in your management processes to continuously improve OH&S for Workplace Airborne Particulate / Fibre Exposure.
