Power washers are powerful tools that can cause serious injuries if they are not used correctly. High-pressure water can cut skin, inject water or debris into the body, and create slip hazards.
What Are the Common Hazards of Power Washing?
The risks go well beyond getting wet.
- High-pressure spray causing cuts or injection injuries
- Flying debris such as rocks, paint chips, and dirt
- Slips and falls from wet surfaces
- Electrical hazards, especially around outlets or equipment
- Chemical exposure from detergents or cleaners
- Noise exposure and vibration fatigue
Why Are Power Washer Injuries So Serious?
What looks minor can become catastrophic quickly.
- Small, painless punctures from water injection can turn into severe tissue necrosis, swelling, and vascular compromise within hours
- Water at over 100 PSI can pierce skin and cause severe lacerations and, in extreme cases, damage to muscle and deep tissue
- Electrical shock is a real risk, such as a worker using a telescopic pole to wash windows who struck a high-voltage power line and suffered severe shock and serious injuries
- Survivors have reported extreme pain, including hands curling, requiring multiple surgeries and skin grafts
- Debris such as rocks or woodchips projected by the washer can cause severe eye damage
What PPE Is Required for Power Washing?
Wear protection for your eyes, ears, hands, and feet.
- Safety glasses or a face shield
- Hearing protection
- Gloves, with cut-resistant recommended
- Steel-toe, slip-resistant boots
- Long pants and sleeves
What Are Safe Work Practices for Power Washing?
Treat the wand as if it is always pressurized.
- Never point the wand at yourself or others
- Always assume the washer is pressurized
- Keep hands and body away from the spray tip
- Use the correct nozzle for the job and avoid unnecessary high pressure
- Maintain a firm grip, since pressure can cause kickback
- Be aware of your surroundings, including people, vehicles, and windows
- Do not use ladders while power washing
- Watch for trip hazards like hoses and cords
What Should You Check Before You Start?
A quick pre-start check prevents failures mid-job.
- Inspect hoses, connections, and the spray gun
- Check for leaks or damaged parts
- Ensure a proper water supply
- Secure the work area and keep others clear
