But some kinds of products cannot be successfully formulated using water, and still contain organic solvents. You need to know the potential hazards associated with those products, and how to avoid them. The label will tell you. Directly underneath will be a statement of the principal hazard, followed by any other hazards associated with the product's ingredients. The precautions are followed by first-aid instructions in case of an accident, and by any special instructions for storage, cleaning up spills, or even disposing of leftover paint.
Some paints contain flammable or combustible materials.
Eliminate all sources of flame, sparks, and ignition. Put out pilot lights by turning off the gas, and do not relight until well after the room is free of fumes. Don't use electrical equipment that could spark. Make sure light bulbs aren't exposed to sudden breakage. Clean up any spills promptly, and dispose of the spilled paint and rags or other cleanup materials safely.
