The list of material hazards is extensive when dealing with paints and solvents. Things you touch or breathe. Things that present a fire or explosive hazard. In Canada graphic symbols are assigned and printed on packaging to warn and direct you in your work. Health Canada provides information on specific chemicals and can also be used along with the book, The Artists Handbook of Materials and Techniques by Ralph Meyer. It is also worth considering materials that are new to the market and not tested for stability.
