Are Pressure Washers Dangerous? 

Your garden hose and detergent can handle several cleanup jobs, especially if you can spend all day sprucing the interior and exterior of your house. However, if you have additional things to do, which may be pretty much involving, then you should go the pressure washer way! A pressure washer speeds up strenuous tasks, including scrubbing grime as well as mildew. Should you see the need to invest in a pressure washer, then you need to be aware of its precarious nature. A lot of pressure washers are used for the first time in the new year around springtime, where almost everyone is focused on taking out their cleaning devices to clean their paths, yards, as well as old cars. Given the rise in demand for this machine in various households, a recent survey revealed that annually, an estimated 5,000 individuals are fatally injured by this machine and rushed to different hospitals.

Generally, there are various types of pressure washers. Some have gas engines, and others use electric motors coupled with a pump and a concentrating nozzle in boosting water pressure from the hose connection. While a garden hose alone can efficiently deliver water pressure at 60 pounds per square, a pressure washer can complete the same tasks by generating up to 4,000 psi. That’s significantly a lot of power. However, when properly operated, the machine can blast away stains from various surfaces without damaging your property.

Even with these benefits, pressure washers can cause serious injuries. That is why consumers appreciate the seriousness of this machine. A pressure washer’s spray is pretty hazardous, especially when misdirected. It can damage your skin. This and more will be discussed in the next segment of this article.

Risks Of Using Pressure Washers

Potential Risks For Physical Injuries

It is typical of people to underestimate the power of a pressure washer. But, the water from the device is stronger than the garden hose. That kind of pressure can definitely cause intense physical injuries, not only to the feet but hands as well.

It can also cut through heavy-duty boots. Other than that, the pressure makes it hard for you to control the hose. This increases the chances of having a runway hose, which may cause injuries. The pressure from the water spray can also strip your flesh from the bone.

Additional injuries from pressure washers are such as abrasion, blindness, high-pressure injection, as well as falls. Sheer pressure water is also powerful to cause injuries. At the same time, using chemicals when cleaning can aggravate a bad situation. The injuries sustained when cleaning using a pressure washer may appear benign. However, they need to be examined and then treated by a physician.  Abrasions are highly associated with pressure washing. To reduce such risks, you should wear protective gear such as gloves and boots.

High Risks Of Electric Shock

Pressure washers are precarious because of the fact that you need to mix water and electric power.  These machines also contain power cables, a feature that makes them susceptible to cracking. Since you are working with water, water mustn’t seep into the cords because it can result in electric shock and fire. You should also have a power source that’s grounded since it eliminates the risks.

Causing Damage To Surfaces

A hardscape can beautify your landscape. It also helps you to save water and then provide a stable surface for parking and entertaining. Mainly, hardscapes are prominent for durability as well as longevity. This feature allows you to enjoy sidewalks and walkways. For the most part, hardscapes are like paving stones.

When dirty, a pressure washer can be used to clean these surfaces. Pressure washing comes with a lot of power. This makes it an invaluable tool for cleaning. Therefore, the pressure may harm your hardscape and other surfaces alike. Washing too close may also cause permanent damage to paint and wood. Not only can the paint chip away, but fade too. If you’ve lead paint on the surface, it will easily chip away due to pressure washing. If the hose of your pressure washer isn’t positioned correctly, it may get underneath, thereby damaging insulation and wiring. 

Chemical Exposure

If your landscapes are dirty, then you need a pressure washer to remove the dirt appended in them. Hiring a professional with vast experience in cleaning would come in handy. This is one sure way of avoiding damage coupled with the potential for expensive repairs.

If hiring one isn’t within your budget, then you should invest in a pressure washer, which comes with a manual for your usage. That said, power washing involves cleaning various cleaning chemicals. If these substances seep into a puncture, crack, or wound, they may cause adverse health problems. The chemicals can also lead to various bacterial infections coupled with other health hazards that may get into your bloodstream.

Destroying Your Shingles

Older windows and shingles may not be able to withstand the pressure associated with pressure washing. You will realize that some shingles, depending on the nature of the material used to design, will be compromised in many ways. A professional with experience in pressure washing can examine your home or a commercial premise before you invest in a pressure washer. He or she should let you know whether it is prudent to invest in the pressure washer.

The Risk Of Damaging Your Skin

Pressure washers emit high pressured water. A small cut may go a long way such that what may seem like a small puncture may signify grave damage. Chemicals from the machine can easily be transmitted directly into the bloodstream. This can result in a bacterial infection.

While a pressure washer is effective when it comes to cleaning various parts of your home, you should be careful when using it. It is crucial to go through the safety manual before putting the machine to use.

Here are a few things regarding what may go wrong when using your pressure washer:

  • Aimed at you: In cases where the pressure washer is aimed directly, the device can break up the surface of your driveway. Here, you may realize that the appliance has created innumerable cracks as well as voids on that surface.
  • Electric shock: If you fail to follow security instructions, then you might get an electric shock with electric pressure washers.
  • CO2 Poisoning: The small engine of the pressure washer is powered by gasoline. It can be precarious if operated in an enclosed space. This will lead to CO2 poisoning.
  • Changing the nozzle: Attempting to change the nozzle of the pressure washer with your engine running may be disastrous too. This can damage the surface you are trying to clean. When water seeps into the wood, it can affect the quality of the painting.
  • Infection: Over the years of people using pressure washers in their homes, there have been several reported cases where owners have had minor injuries that led to infection. The infections turned into disability. Remember not to neglect wounds caused by your pressure washer. Other than that, taking additional precautionary measures will be instrumental in cutting the risk factors of this equipment.
