Paint Sprayer Safety: Everything You Need To Know

When it comes to safety, the best thing you can do is read the safety manual that comes with your paint sprayer. If you do not have the manual that comes with the sprayer you are operating, we encourage you to find a copy as airless sprayers are different from brand to brand and model to model. Many of these manuals can be found online. Safety is one of our main priorities, so here HCC Airless Repair discusses everything you need to know when it comes to paint sprayer safety.

Safety Hazards

Fire and Explosion

Fire and/or explosion can occur if the sprayer is spraying flammable fluid in an area where air circulation is poor and an open flame or sparks are present. Many particles can ignite, causing a fire or explosion. The most common cause of a fire or explosion is the ignition of flammable vapors by an open flame or spark. With an ungrounded spray system, the flow of fluid through the sprayer and hose may create enough static electricity to cause a spark from the gun. That spark can ignite flammable vapors.

Injection of Spray Material

Injection can be caused by the high-pressure fluid passing through a small opening, such as the spray tip or hose leak. This creates a high-speed stream of atomized fluid that is powerful enough to pierce your skin and enter your body. Injection occurs when the high-pressure fluid pierces your skin. Typically this occurs when you place a part of your body too close to the spray tip or by grabbing a leaking hose or fitting. If you happen be sure to seek medical attention ASAP. As many think it’s just a minor cut this can be very detrimental to your overall health.


Safety is the main concern when dealing with paint sprayers and hazardous chemicals. To help prevent a fire and/or explosion when spraying flammable materials, it’s recommended to spray in a well-ventilated area. A non-sparking fan can be used to help air movement and reduce the risk of fire or explosion. Other fire prevention measures include:

  • Remove and dispose of all potential ignition sources. (cigarettes, pilot lights, furnaces, etc.)
  • Place gas powered sprayers outside the building and run the hose into the room to be sprayed.
  • Keep the work area free of debris that could contribute to a fire. (open cans, rags, paper, etc.)
  • Use only grounded hoses.
  • Check hoses periodically for electrical continuity using and ohm meter.
  • Ground the sprayer regardless of the power source.

To help prevent injection injuries…

  • Always use to the tip guard when spraying.
  • When not spraying, always use the spray gun trigger safety.
  • Relieve fluid pressure when cleaning or servicing any part of the equipment.
  • Point the gun away from yourself and others at all times.
  • Do not try and stop leaks with your hand or body.
  • Remove the spray tip, reduce the material/fluid pressure and immerse the gun nozzle in the fluid when flushing.
