The job hazard analysis
PPE required: Safety glasses, Gloves, Safety boots, Hearing protection
1. Inspect the equipment
What could go wrong
Burst hoses; leaking fittings
How we control it
Check hoses, fittings, and the trigger lock. Don't use damaged parts.
2. Set up the area
What could go wrong
Slips; water near electrical equipment; spray hitting others
How we control it
Keep people out of the spray. Keep electrical equipment dry and use a GFCI. Block off slippery areas.
3. Wash
What could go wrong
Injection injuries from the jet; kickback
How we control it
Never point the jet at a person or at your own foot or hand. Hold the wand with both hands and brace for the recoil.
4. Shut down
What could go wrong
Stored pressure
How we control it
Release the pressure before you disconnect. Drain and store the hose.
- A high-pressure jet can break the skin. If it does, seek medical help right away, even if the wound looks small.
When to use it
Use it for any pressure washing, and review it when the pressure, surface, or location changes.
Review it with the crew before the work starts, change anything that doesn't match how you'll do the job, and update it when the method, the equipment, or the site changes.
