4. Training of RGL Personnel4.1. All RGL personnel will hold a minimum of the Water Jetting Association (WJA) Safety

Awareness card. This mandatory training is completely every 3 years by all personnel.

4.2. Before commencing work on site all RGL staff will undergo training modules that are

assessed in house that covers the safe operation of our Water Jetting equipment.

4.3. All RGL personnel will hold a Construction Skills Certification Scheme (CSCS) card

applicable for their level;

4.3.1.Trainee water jetting operatives and newly qualified water jetting operatives will hold a

‘Red Trainee’ card.

4.3.2.After one year, Trainee Water jetting operatives will be put through a Water Jetting NVQ

2 which usually takes between 4-6months to complete so they can progress to a ‘Blue

Experienced Operator’ card.

4.3.3.All RGL personnel after 2 years will hold a ‘Blue Experienced operator’ card in Water

Jetting.

4.4. All RGL Team Leaders will hold a valid Site Supervisor Safety Training Scheme (SSSTS)

within 6 months of becoming a Team leader.

4.5. All RGL personnel will hold a Client Contractor National Safety Group (CCNSG).

4.6. Other specialist training will be undertaken as required and include the following;

4.6.1.City and Guilds Confined Space – High Risk

4.6.2.International Powered Access Federation (IPAF)

4.6.3.Personal Track Safety (PTS)

4.6.4.Telehandler

5. Standard Water Jetting practices to be carried out5.1. The RGL operators will be inducted by the Client and sign on to the RAMS.

5.2. All jetting works are to comply with ‘The Water Jetting Association Code of Practice 2015’

5.3. All RGL equipment will come with a Pre Delivery Inspection (PDI) sheet that has been

checked and fulfilled by the RGL workshop. This will be available for inspection in the Site

Health and Safety File.

5.4. RGL Team Leader will complete a daily safety check on the plant and equipment before

first use.

5.5. The jetting unit will be placed as close to the works location as possible.

5.6. Water inlet hoses will be connected between the potable water supply and jetting unit. The

inlet hoses will be positioned so they do not cause a trip hazard to the other site personnel

and be marked with barrier tape and signs if required.

5.7. UHP hoses and control cables will run from the jetting unit location to the work area–

avoiding walkways where possible. All HP hoses will be fitted with a whip check at each

joint.

5.8. Where possible, a 10m exclusion zone will be erected around the work area. ‘NO

UNAUTHORISED ENTRY HIGH PRESSURE WATER JETTING IN PROGRESS’ signs

will be prominently displayed.

5.9. Where a 10m exclusion zone is not possible, a solid barrier (steel plate) that will not be

penetrated by the water jet must be used to segregate working areas.

5.10. The noise generated by the jetting operation will be in excess of 100dB and adequate

hearing protection will be required within a 10m radius of the jetting operation.

5.11. The jetting operation will be performed by a minimum of a 2 man team. One man to

control/operate the water jetting at the work face. The second man is the safety stand by to

ensure no unauthorised access to work area and responsible for shutting down the jetting

unit if required to do so. The jetting unit can be shut down using an inline stop switch that

allows the safety stand by man to be away from the jetting unit and still have control.

5.12. All hoses will be flushed through without a jet to ensure no grit/debris in the line. Once

flushed through for 1 minute the line is clear and the jet can be put on.

5.13. The setup of the UHP pump and connections will be checked by the operator. The jetting

unit will be warmed up and then the operator will pull the trigger of the safety gun. The

safety standby man will set the pressure of the jetting unit. The machine will act as a

stand-alone unit and will stop automatically when the operator releases the trigger or any

of the safety stops are activated, e.g. over pressure, low water, engine problems etc. The

high pressure water will be pumped through the hose to the safety gun/accessory.

5.14. The automated equipment/operator will pass the jet over the surface to be removed cutting

the concrete into aggregate size pieces.

5.15. The work enclosure will be monitored at all times by the safety standby man to ensure

debris is contained. Should containment fail the jetting operation will be stopped and

repairs made.

5.16. Every 1.5 – 2 hour the operators will swap roles to reduce fatigue.

5.17. On completion of the jetting works the area will be inspected by the client. Additional works

will be carried out as instructed.

6. Site Specific Methodology6.1. Insert text here

7. Environmental 7.1. Where possible RGL will use UHP instead of traditional HP water jetting which results in

using approximately half the water at a rate of 27litres/minute.

7.2. All RGL vans will come complete with spill kits to reduce the impact of any environmental

spill.

7.3. All RGL diesel/petrol plant will be sat on a suitable drip tray.

7.4. Waste water produced from Hydrodemolition will be discharged as per clients request into

a suitable location.

7.5. The noise created from Hydrodemolition is in excess of 100dB (A) and therefore an

exclusion zone of 10m is to be maintained where possible. When this cannot be

maintained the client is to make suitable hearing protection available to personnel within

10m.

8. Emergency Procedures

In the event of a serious incident requiring attendance by the emergency services, 999 should be called. The caller should provide details of the nature of the incident and precise location details. At the earliest opportunity, contact should be made with the clientA first aider will be contactable at ALL times.

As stated in WJA Code of Practice 6.0.6 ANY PERSON INJURED BY THE IMPACT/PENETRATION OF A WATER JET MUST SEEK EXPERT MEDICAL ADVICE IMMEDIATELY.Please see laminated copy of ‘High Pressure Water Jet Injuries’ in Section 12 of the Site Health and Safety file that are to be shown to the medical expert.

9. Risk Assessment

Shown below is a 5x5-risk assessment matrix upon which the quantitative values shown in the Risk Assessment are based.

Where:Likelihood of an event happening Severity should an event happen1= Extremely Unlikely 1= First Aid Injury, No lost time,

2= Unlikely 2= Minor Injury, less than 7 days absence

3= Likely 3= Reportable injury, more than 7 days absence

4= Very Likely5= Almost Certain

4= Major injury, long term absence5= Fatality

Principle of EvaluationThe risk (R) has to be evaluated for each of the hazards identified based on the principle of;

Risk (R) = Likelihood (L) x Severity (S)

Scores with an R between: 1-9 are acceptable.Scores with an R between: 10-25 are not acceptable and must have further measures implemented.

Stress/strains

3 4 12 Yes All lifting of equipment should be carried out using mechanical means if

available.

The TILE procedure to be considered and adopted to reduce any further risk

when manual handling is required;

TASK: Does it need to be done often?

INDIVIDUAL: Only lift within your own capabilities. Can the manual handling

be shared to reduce the load?

LOAD: Is the load less than 25kg? Can the load be split to reduce weight?

Can a good grip be gained?

ENVIRONMENT: Are there any factors that could affect the load? Weather?

Height obstructions? Uneven floor surfaces?

If uncertain contact the office for further guidance.
