A pressure washer is a useful, versatile tool for removing paint, mold, grime, mud, and dirt from surfaces that many homeowners and businesses find invaluable. But its high-pressure water spray can present striking and impact hazards, both from the spray and from any objects or debris being sprayed. Its electrical or gasoline power sources also carry risks that an operator must be familiar with. It’s vital to remain careful when operating a pressure washer and to adhere to the manufacturer’s safety instructions. Learning what precautions to take and what mistakes to avoid before you begin working will help keep you safe.

What to Do:

• Be aware of your surroundings, especially any people nearby. Inform people of your work so that they can keep a safe distance.
• Wear appropriate protective gear and clothing, including safety goggles, gloves, hearing protection, long pants, and closed-toe shoes or boots with insulating rubber soles.
• Test the ground fault circuit interrupter before using an electric pressure washer, and always plug a properly grounded washer into a properly grounded outlet.
• If a pressure washer has tripped the circuit breaker, have it examined by a qualified electrician before using it again.

What to Avoid

• Never point the nozzle at yourself or another person.
• Never allow children to operate a pressure washer.
• Never push or move objects by spraying them with the washer.
• Never cut or splice the washer’s power cord or extension cords, and never remove the grounding prong from the cord plug or extension cord.
• A gasoline-powered pressure washer is a carbon monoxide poisoning hazard. Never use one in an enclosed space or less than 20 feet from a window, door, or event.

If injured by a pressure washer, make sure to follow common first aid guidelines.

• Wash your hands with soap and clean water before caring for any wounds.
• Put pressure on a wound with a clean cloth to stop the bleeding.
• Pour clean running or bottled water over a wound after bleeding has stopped, and clean around the wound with soap and water.
• After cleaning and gently drying a wound, cover it with an adhesive bandage or dry, clean cloth. Never close or cover a wound until it has been properly cleaned.

Most importantly, get medical attention as soon as possible and don’t be afraid to call 911 if necessary. Seemingly minor wounds can be worse than they initially seem, and dirt or debris blasted from a pressure washer can easily cause adverse health effects. You may need an X-ray for potential breaks or fractures, antibiotics to prevent infection, or a tetanus shot.
