Your Chances of being Injured in

an Accident are: 1 in 11

Why to Care?

3) If we reduce number of Accidents we will

reduce the chances that one of us will get Hurt

Hazards of Hydro jetting

Piercing of Body Parts Even small cuts can be Infected & lead to serious health issues

Flying debris/deposits

Release of hazardous materials

Noise

Breathing Difficulty (water Vapour)

Electrostatic charging of nozzles and lances.

Very High Pressure > 20,000 PSI *Just think - car tire pressure is 35 PSI

The next Slides explains the minimum steps

to done for safe Hydro jetting work:

Understand and Follow Them If you are not sure or feel un-safe

Stop work and ask for advice; we are here to

help you

Safety

What to Do?

Valid Permit must be available at

work site at all times.

If permit is not at site STOP JOB

Permit should not be away from

worksite or be taken by foreman

or any of the workers

No Permit No Work

1. Permits

2. Toolbox talk

At site & At start of each shift Supervisors must:

Explain Hazards & Controls

Explain Permit requirements

Check for understanding Ask team members to tell you the

main point in their own words.

Repeat Major Points.

Document in writing & get

signatures of all workers.

3. Barricade Work Area

Barricade Area of effective range of the jetting equipment

Use suitable barriers to prevent unauthorized entry

Put Signs DANGER HIGH PRESSURE WATER around work area

4. Shield against water/debris

Protect against water splash, Use tarpaulin sheets to cover area Around Exchanger specially back end; support with scaffold.

This will protect other

people behind or

outside jetting area

Air Coolers and exchangers at Height: Use tarpaulin sheets with drain &hoses to

Protect and to collect dirt water and debris

Always use drip pan to collect dirty water Before it gets full Empty into Barrels

5. PPE Hydro jetting Operators to use turtle suit &

Face Shields

It might be heavy but it will protect you

Always 2 operators, one taking rest & 2nd

jetting swap at regular intervals

turtle suits are Armored re-enforced

6. Scaffold

Ensure TAG available, Signed & Valid

Do not Modify Scaffold; Request your Supervisor to call scaffolding team.

7. Hydro-jetting Equipments

Machine must have fail safe system with

proper control mechanisms. (e.g. Foot

operated shut-off valve & Dump valve)

Before starting Jetting Machine Competent

Operator to perform full Inspection on

Machine, Pressure fittings, Hoses, Lances,

Nozzles and Safety equipments.

Use Check List; Sign to confirm readiness for

safe operation.

8. Check Hoses & Fittings

Ensure all Hoses & Fittings are laid down in supported and protected positions.

Away from sharp objects No tripping hazard

Ensure all Hoses have whip check Prevents Injury If a hose connection separate

Ensure all Hoses & Fittings are in good condition

9. Hydro jetting Operators

Pump Operator

Attend the pump unit & Ensure all Equipments in Safe Condition

keep close watch on the Jetting Lance operators for signs of difficulty or

Lance /Gun operator

2 members; each rotate their duties during any job to minimize fatigue

One operator holding the lance or gun and the 2nd operator to watch the

surrounding area for unsafe situations

If you are tired or do not feel good

Stop Work & Request Replacement

10. Unsafe Act/Condition examples

No Protection/Cover at the back side

People at that area can be hit by

water jet and flying debris

Slippery Surface

Hydrocarbon at ground (fire Hazard)

No Barricades/ signs

Water jet and flying debris
