A pressure washer is a power tool that sprays water at high pressures to clean large, sturdy surfaces such as buildings, farm equipment and roads. Pressure washers deliver extreme pressure that can cause serious injuries if misused. Before starting a pressure-washing project, it is important to properly prepare the work site and consider some safety tips. Below we categorize safety procedures according to the equipment safety usage, personal safety usage and included some Safety Cleaning Tips.

  • Don't allow any cleaning solution to sit on the surface long because it may dry and leave residue.

  • Do not use bleach, as it will damage parts of your pressure washing equipment.

  • Don't leave your pressure washer nozzle closed for more than one minute while the pressure washing equipment is still running as it may cause stress to the pump.

  • Do not use hot running water in your cold water pressure washer.

  • Make sure to check the engine oil level each time you use your pressure washer.

  • When changing or adding oil, do not overfill the engine crankcase. Overfilling oil may cause smoking, hard starting, spark plug fouling, and oil saturation of the air filter.

  • Maintain a minimum 6-ft. distance when spraying water around power lines, electrical masts or outlets.

  • Never attempt to repair a damaged high-pressure hose. If the high-pressure hose is damaged, replace with a new one.

Personal Safety Usage

  • Follow the manufacturer’s directions regarding power washing attachments, nozzles, and the right pressure washing chemicals.

  • Don't point the pressure washer at people or pets or put your hand in front of the nozzle. The pressurized water stream could actually penetrate your skin or cause serious cuts.

  • Wear safety glasses when operating the washer.

  • Don't use pressure washers while working from ladders. Once you squeeze the trigger, the powerful recoil on the spray wand can throw you off balance and off the ladder.

  • Before uncoupling hoses, stop the machine, turn the water faucet off and squeeze the spray wand trigger to release all water pressure in the system.

  • Engage the safety lock on the trigger when you're not actually washing and when changing nozzle tips.

  • Avoid spraying windows or glass doors because the force of the jet might break the glass.

  • Do not leave a pressure washer unattended while it is running.

  • Don’t ever allow children to operate the pressure washer for everybody’s safety.

Safety Cleaning Tips

For safety’s sake clean the house from a ground level. Using a ladder with all that slippery detergent and water can be hazardous. Use spray arm extensions and brushes to more effectively reach high spots and clean a dirty house or prep it for a new paint job.

Cleaning results vary based on how wide you set the spray angle of your unit’s nozzle, from pin-point to wide fan. Take the time to test varying angles to discover what works the best. When you find and use the best spray angle for each job, you can reduce the time avoid delays while determining the right angle to get rid of dirts especially in the surfaces that are hard to reach.

Use the right nozzle before you accidentally harm some surfaces. Avoid using nozzle that concentrates on too much power. Before using the nozzle on a very visual area, test it in an inconspicuous area. Also test the pressure washer in a small area out of sight to make sure that the pressure spray will not damage the material.

Pressure washers are equipped with safety features designed to reduce pressure build-up. Examples of them are Un-loaders and thermal relief valves which prevents heat and water pressure from reaching dangerous levels. They have also Oil-level indicators to ensure that the washer stays properly lubricated.
