The following guidance is given for the safe use of paints and varnishes/mediums items supplied by Art Req.
Linseed and Poppy Oil are not considered toxic. Vegetable oils, however, can self-combust (slowly ignite into fire) particularly when on or in rags. Always dispose of rags with care by soaking in water first.
Any paints containing Lead like Flake White / Foundation White / Cremnitz White, can kill or harm an unborn child, even immediately after conception—so if you considering pregnancy, avoid contact. Lead is also known to be toxic for children and adults. Keep these products away from children, even if they are the constituents of a dry, finished painting. Do not eat or smoke while working with these paints. Do not sand surfaces containing these or any paints where you can inhale the dust, the alternatives are Zinc Oxide and Titanium Dioxide.
Lemon Yellow must be treated in the same way. It contains Chrome and Barium that causes a lot of other problems. These are several Lake Yellows which can substitute for these when mixed with Titanium White.
Cadmium Colours are not officially subject to the same regulations covering lead-based products but should still be handled with care. If they are burnt cadmium is released in a form which is highly toxic.
As a general precaution, do not allow paint into contact with your skin in such a volume that might cause skin sensitivity. There are also possibilities that some toxic pigments might be able to enter through the skin when used in conjunction with solvents.
Always wash well after use and before eating. Make sure your studio is well ventilated.
ALWAYS DISPOSE OF USED PAINT TUBES OR SOLVENT CONTAINERS CORRECTLY, THESE SHOULD NOT BE PUT IN WITH GENERAL HOUSEHOLD WASTE
