Are Pressure Washers Dangerous?

Pressure washers can be incredibly useful tools for cleaning a wide range of surfaces, from driveways to decks and even vehicles. However, their potential for danger should not be discounted because it lies beneath their usefulness.

The enormous force with which pressure washers release water is at the core of the potential threat they pose. For lighter-duty devices, the pressure may be as low as 1,000 pounds per square inch (psi), while for commercial-grade equipment, it may be far over 3,000 psi. Pressure washers use this pressure to blast away filth, grime, and debris, but if not used carefully, it can also cause significant injuries.

The potential for bodily damage is one of the main risks. Pressure washers emit a high-pressure water jet that can easily puncture the skin, resulting in tissue damage and serious wounds. Even moderately powered pressure washers can be dangerous, especially if the water stream comes into contact with delicate body parts like the eyes. Such accidents may cause severe eye injury, including blindness.

Additionally, pressure washers have the ability to harm surfaces and structures. When exposed to the force of high-pressure water, concrete, wood, paint, and other materials may be eroded, peeled, or otherwise degraded. Pressure washing a fragile surface might result in unintentional damage and expensive repairs in the hands of an unskilled user or someone who is unaware of the necessary practices.


A Pressure washer injury may vary from case to case, and the severity of these injuries might differ. However, we will discuss a few common pressure washer injuries, from minor accidents to events that can pose serious threats to your body or, in severe cases can be life-threatening.

1.      Slips/falls

The most common and overlooked occurrence is a slip or fall due to the pressure washer. An electric pressure washer emits water at around 1000 PSI while a gas pressure washer can reach from 2000 PSI to 4000 PSI, making pressure washers the most effective outdoor cleaning equipment. But simultaneously, the pressure washer gun’s backwards force is enough to throw a person back. In such cases, if you have not been holding the pressure washer on a smooth surface, it may lead to severe injury.

2.      Abrasions

Abrasions are mainly caused when the pressure washer is accidentally pointed toward your own hand or foot. Because water is ejected from pressure washers with a great deal of force, this can result in abrasions on your body. If not utilized carefully, pressure washers can also irritate the human body. A pressure washer’s high-pressure water stream can be powerful and possibly damage the skin. The effects of solid friction might cause skin abrasions if the nozzle is pointed toward the body too closely or at an incorrect angle.

3.      HPI injection infection

An HPI (High-pressure Injection) injury can develop when a high-pressure pressure washer filled with fluids or chemicals is forcibly injected into the body. High pressure can harm the tissues significantly and increase the risk of infection by forcing the injected substance deep into the tissues. The material injected can harm the surrounding tissues, blood vessels, and nerves, resulting in tissue necrosis, scarring, or even limb amputation.

HPI injections are regarded as urgent medical emergencies that must be attended to and treated immediately to limit further harm and potential long-term problems. High-pressure water injection injury symptoms include pain and local swelling that may become severe a few hours later. The wound is small and not apparent. However, the underlying damage may be severe.

4.      Electric shock

If not used appropriately, pressure washers can cause electric shocks. Water and electricity are hazardous together. Faulty wiring, damaged power cords, or inadequate grounding might increase the danger of electric shock. Burns, cramps, breathing difficulties, and, in severe cases, cardiac arrest may result from this. When using a pressure washer, it is essential to ensure that it is connected to a properly grounded outlet, check the power cables for any damage, and never use the equipment in wet conditions to reduce the risk of electric shock, also known as pressure washer death.

5.      Carbon monoxide poisoning

When utilizing a pressure washer in an enclosed or poorly ventilated area, carbon monoxide (CO) poisoning could result. Exhaust emissions from pressure washers powered by internal combustion engines, such as gasoline or diesel, include carbon monoxide. The exhaust fumes from these engines can build up to deadly levels if used indoors, in a closed garage, or in a small area without enough ventilation. Carbon monoxide, an odorless, colorless gas, is highly hazardous when inhaled.

Carbon monoxide is mixed in the blood’s hemoglobin when inhaled, making it less effective at carrying oxygen throughout the body. Headache, dizziness, weakness, nausea, confusion, and, in severe cases, unconsciousness or death are just a few of the symptoms that can result from this oxygen deficiency.


No matter how sharp your cleaning instinct is, it is not worth enough to cost you your life or a severe pressure washer hand injury, a foot injury, or a pressure washer finger injury. Fortunately, it is not difficult to avoid pressure washer injuries if handled with care and precaution. I will discuss some essential safety precautions to help you avoid accidents.

1.      Wear Protective clothing and gear

Eye Protection: Safety goggles or a face shield protect the eyes from debris, chemicals, and high-pressure water a pressure washer may throw. This guards against eye injuries such as corneal abrasions, chemical splashes, and strikes from foreign objects.

Sturdy, non-slip gloves protect against potential cuts, abrasions, and chemical exposure. They minimize the possibility of skin harm by providing a barrier between the skin and the high-pressure water stream.

Footwear: To defend against falling objects, jagged debris, and unintentional slips or falls, wear solid, closed-toe shoes with non-slip bottoms. They also provide a barrier against chemical leaks and foot injuries caused by the pressure washer.

Wearing protective clothing, such as long-sleeved shirts and pants made of sturdy fabrics like thick cotton or denim, can help prevent skin damage from coming into contact with substances like high-pressure water, chemicals, or abrasive surfaces. Cuts, abrasions, and chemical burns are avoided as a result.

Hearing protection, such as earplugs or earmuffs, is advised when operating a gas-powered pressure washer due to the engine’s and pump’s noise. Long-term exposure to loud noises can harm your hearing.

2.      Set the correct pressure

Pressure washers have different pressure settings that they operate in. It is always advised to keep the pressure setting at its lowest initially. It helps avoid many accidents or damages.

Not all surfaces are prone to high pressures, leading to surface damage. High-pressure settings may be a turn-off for fragile surfaces like wood and painted surfaces. Also, when hitting a solid surface, high-pressure streams can create a forceful kickback, leading to falls. Besides, a suitable pressure setting keeps the water stream from becoming overly forceful. Excessive pressure can harm people by removing layers of skin, causing abrasions, or even piercing sensitive tissues.

3.      Check for any electrical hazards

Ensure that the pressure washer is connected to a GFCI (Ground fault circuit interrupter), as they are designed to detect any electrical imbalances and instantly shut down the power if it finds any imbalance to avoid an electric shock.

Inspecting all the power cords for any cuts or exposures and replacing them if necessary is also essential.

Ensure all the electrical components are dry, as water or moisture can conduct electricity and lead to electric shock.

If you require an extension cord, ensure a pressure washer supports it. Use extension cords specially designed for outdoor power equipment.

Never try to modify or tamper with the pressure washer’s electrical connections. Only authorized workers should make any electrical repairs or modifications to maintain safety.

Before doing any maintenance or troubleshooting on the pressure washer, make sure the power is switched off, and the device is unplugged from the power source. By doing this, unintentional electrical shocks during maintenance procedures are avoided.

4.      Inspect your surroundings

When starting to pressure wash an area, inspect your surroundings and remove anything that might get harmed or injured. Remove any garden furniture, vehicles, or outdoor plants if you are cleaning an outdoor area. Also, keep your pets, kids, or other members out of sight to avoid any pressure washer injury.

5.      Never aim the pressure washer at yourself

We should avoid directing a pressure washer at our bodies to minimize any injury. The high-pressure water stream produced by pressure washers can hurt the skin, muscles, and tissues. The powerful water jets can cause deep tissue injury, lacerations, or abrasions. Further harm can result from the high-pressure stream’s ability to push water and debris into vulnerable places like the eyes, ears, or open wounds. Depressurize

6.      Engage the safety latch

A pressure washer’s safety lock must be activated to avoid accidents and ensure safe operation. The safety latch, often found on the pressure washer wand’s trigger, aids in keeping the trigger locked in place. Activating the safety latch decreases the risk of unintentional water spray and associated injury because the trigger is prevented from being pushed accidentally.

7.      Be cautious handling gas-powered washers

Gas-powered washers can emit a lot of carbon monoxide, a suffocating gas. It is, therefore, imperative to avoid using gas-powered washers in enclosed areas. Carbon monoxide is an odorless gas that is highly toxic and can cause severe symptoms or, sometimes, be fatal. The carbon monoxide is inhaled into your bloodstream and causes oxygen deprivation. A headache, weakness, and dizziness are the first symptoms, followed by nausea and confusion. However, the symptoms come on so suddenly that you swiftly lose consciousness. Use a gas-powered pressure washer only in the garage with the door fully open to prevent harm in this way.

8.      Engage a professional for the job

Although it is elementary to buy or rent a pressure washer, it is easier to operate one. I recommend seeking help from pressure washing services, as they are professionals who charge a small fee for this task. Some pressure washing services offer affordable packages and thorough outdoor cleaning. Many times, a job can be done without a pressure washer. Check out these articles.
