CDC Pressure Washer Safety

Pressure washers are useful in a number of situations and are often used in industry. There are dangers when using one, and the Centers for Disease Control recommends several safety procedures.

Function

• The pressure washer is a versatile tool that cleans large surfaces using water. Sprayed out at extremely high pressure, the water is able to remove hard, stuck-on grime, dirt and other substances. It is used to clean items such as farm machinery, the sides of buildings and road surfaces.

Risks

• If you use an extension cord, keep the cord out of pooling water.

  The pressure emitted from the washer can send an object airborne when hit by the water. A washer with a gasoline engine can emit carbon monoxide, which can be poisonous to the user. The danger for exposure to this gas is greatest in tight spaces that are not well-ventilated. Sustaining an electrical shock can occur if precautions aren't used.

Prevention/Solution

• Plugging the washer into a ground fault circuit interrupter can prevent electrocution. When using the sprayer, you should never point in the direction of another person. If you use an extension cord, the connection between it and the sprayer's cord needs to be kept clear of pooling water. To avoid sending objects flying, do not use the sprayer's water to move items.
