Guys don't play games with shooting paint. ALL latex paint contains SOLVENTS. It's just less than oil or solvent based paints. Read the can it says it right on it...Glycols etc are solvents....


BE SAFE.

Water is also a solvent. We drink alcohol and glycols are used in the food we eat. Exposure to any material involves risk. We are exposed to risk in everything we do. Some risks are voluntary and others are involuntary. It is the involuntary risk that usually gets people upset. Risk is also cumulative, so eliminating a source of risk, no matter how small, is a good idea as long as its feasible.

Two of the most misused and misunderstood terms in my profession are “dangerous” and “toxic”. All materials are dangerous and toxic in the right concentrations and/or situations. The questions to ask are how toxic based on the exposure I am getting or what are factors that make this material dangerous. OSHA and NIOSH are the good sources for information on most materials. Also check the MSDS. When consulting an MSDS, try to review more than one; some are better than others for the same material.

It is important to read and understand the MSDS for all the materials you are using. By understand, I mean know what terms like flash point, LEL, TWA, and IDLH mean. I have no problem using my dust collector as a vacuum for a spray booth when I am spraying water based paints through an airbrush. My dust collector vents outside the house and there are no filters to clog and there is no chance that the overspray could ignite. I would NEVER put overspray from a “rattle can” through it; the LEL for the material in the rattle can is too low.
