Safe cleaning starts before the machine runs. Operators need to understand the equipment, the work area and the products they will use.
Use this overview alongside the machine manual and your site’s safety procedures. Each task needs controls suited to its hazards.
Prepare the operator
Train operators on the specific machine before use. Cover normal operation, shutdown, warning signs and emergency actions.
Make sure operators know where to find the manual and whom to contact when something goes wrong.
Inspect the equipment
Before starting, check the machine using the manufacturer’s inspection procedure. Look for damaged hoses, loose connections, missing guards and signs of leaks.
Stop if you find damage or an unsafe condition. Report it and arrange repair before using the machine again.
Check the work area
Identify nearby people, traffic routes and surfaces that may become wet. Plan hose and cable routes to reduce trip hazards.
Use the controls required by your site to keep people clear of the cleaning area. Review access and exit routes before work starts.
Handle chemicals as directed
Read product labels and safety data sheets. Confirm protective equipment, dilution, storage and spill procedures before handling the product.
Never mix different cleaners together. Provide training in language and terms operators understand.
Review pressure washer hazards
Never direct a pressure washer at yourself or another person. High-pressure spray can cause serious injuries that may initially look minor. Seek prompt medical attention for a high-pressure spray wound.
Gasoline engines also create a carbon monoxide hazard. Never run a gasoline-powered pressure washer indoors or in an enclosed space. Keep it at least 20 feet from windows, doors and vents, as CDC guidance specifies.
Follow the shutdown procedure
Use the machine manual’s shutdown and servicing instructions. Follow your site’s energy-isolation procedure when required before maintenance or clearing a fault.
Do not bypass safety devices or try to repair equipment while it is operating.
Prepare for an emergency
Before work starts, operators should know:
- How to stop the equipment.
- How to summon emergency help.
- Where required emergency supplies are located.
- How to report an injury, spill or equipment failure.
Review incidents and near misses so the team can correct problems before the next job.
Keep maintenance on schedule
Record inspections, faults and repairs. Follow the manufacturer’s service schedule and make sure reported problems are resolved.
