Fluid injection into your body is very serious!! When working with airless equipment, the pressure is tremendous. That pressure is concentrated to a very fine point at the spray tip. If your Hand or other body part is over that opening when the trigger is pulled, you have a fluid injection injury.
This is very serious and unfortunately most medical centers don’t know how to treat such a wound. I had one on my hand and it was terrible.
When you buy a spray gun or pump with a gun one of the many things most painters throw away is a little packet of information you should keep. I keep one in my wallet and one in the company first aid kit. If you experience this type of injury had the card to medical personnel to help them treat your injury.
The toxicity of what has been injected is secondary to the physical damage to the area. Surgical debridement of the area is the first concern and many latex paints and paints with titanium dioxide reduces your systems ability to fight infection so an immediate course of antibiotics is necessary. Fluid injection is a nasty wound and something you definitely want to avoid.
