Common Types of Pressure Washer Injuries

The pressure from an electric pressure washer can range anywhere from 1300-1600 PSI while a gas-powered pressure washer sprays at 2000-4000 PSI. Compared to this, a garden hose sprays water at only 40 PSI. Most users don’t take into account the kind of power a pressure washer operates at which often results in injuries. Let’s take a look at some common types of pressure washer injuries.

Injuries are Often Caused by Improper Handling of Pressure Washers

1) Hand Injuries – If the stream of the pressure washer passes anywhere near your hand, it can cause lacerations or cuts. A small cut might look harmless, but it should be treated immediately as the water can cause infections under the skin. Many people receive injury on their fingers if they move their hand in front of the stream from the pressure washer.

2) Foot Injuries – This type of injury is also common when a person triggers the pressure washer while it is pointed at the ground. The pressure of the water is so high that it can pierce through shoes and damage skin.

3) High-Pressure Injection – HPI or High-Pressure Injection injuries are those when debris or chemicals enter a person’s skin with the water. Such wounds can get infected quickly, and a person should be given immediate medical attention. Most of the time, the cause of such injuries is concentrated spray of water and careless handling of the pressure washer.

4) Slipping and Falling – The water from the pressure washer exerts a lot of pressure against every surface, and it can lead to falls if you are not careful. Many people fall when they use a pressure washer on a ladder, and the backward force from the pressure washer destabilizes the ladder. Slipping because of improper footwear is also another cause of injuries.

5) Eye Injuries – Eye injuries are also common among people working with pressure washers. Accidental sprays into the eyes or splash-back from spraying something too close to the face can lead to blindness and other eye injuries. Many times, the force of the water can send loose debris, nails, glass shards, or chemicals into the eyes.

6) Electric Shock – If the electrical fittings of a location are not switched off or left uncovered, it can lead to electric shock. Electric pressure washers should be used with proper grounding and high-quality wires to prevent shocks of any kind.

7) Hearing Loss – Gas-powered pressure washers are loud, and it can lead to hearing loss if you work in their vicinity for an extended period.

8) Burns – Using hot water while pressure washing can lead to burns if the water splashes back from a surface. If there are chemicals in the vicinity of the pressure washer, they need to be stored properly as the stream from the pressure washer can puncture containers and lead to chemical leakage.

Safety Tips to Prevent Pressure Washer Injuries

Protective Clothing is a Must to Prevent Injuries from Pressure Washer

While there is no sure shot way to avoid injuries and accidents at the workplace, you can take appropriate precautions to minimize the risk of injuries while using a pressure washer. Here are some safety tips you can follow.

1) Protective Gear – Most injuries happen because a person is not wearing suitable gear while using the pressure washer. Thick pants, close-toed shoes, safety helmet, safety glasses, hearing protection, and thick gloves are essential while using a pressure washer.

2) Inspect the Area – Before starting to pressure wash an area, inspect the area in detail to check anything that can be a safety hazard. If there are any debris, mechanical implements, chemicals, open wires, or hazardous substances in the area, remove those before starting to pressure wash the area.

3) Be Mindful – If you don’t intend to wash a surface, do not point the pressure washer at it. Maintain distance from any surface where you are pressure washing. Also, never point the pressure washer at yourself or any other person.

4) Avoid Ladders – Ladders or unstable surfaces can be a significant factor that contributes to falls and slippage. The force from the pressure washer is enough to destabilize ladders or push you off any surface. It is a better idea to use an extension attachment for pressure washing areas you cannot reach.

5) Avoid Zero Degree Nozzles – A zero-degree nozzle or the red colored nozzle concentrates the flow of water to a small point that can be piercing and hazardous to open skin. This nozzle attachment is not recommended by Consumer Report because of its dangerous nature. It is a better idea to use a wide spray for all kinds of cleaning.

6) Avoid Enclosed Spaces for Gas Powered Pressure Washers – If you are pressure washing an enclosed space, consider using an electric pressure washer. Gas-powered pressure washers emit gases that can lead to nausea and headaches. Always use a gas-powered pressure washer in an open space.

7) Do Not Test the Water Pressure – Many people get injured because they try to test the pressure of the water by putting their finger or hand in front of the stream from the pressure washer. Doing this will injure your hand as pressure washers operate at above 1000 PSI, and even 100 PSI is enough to break the skin and cause injury.
