a When stored as a liquid monomer
b Although these chemicals form peroxides, no explosions involving these monomers
c When stored in liquid form, these chemicals form explosive levels of peroxides without concentration. They may also
be stored as a gas
in gas cylinders. When stored as a gas, these chemicals may autopolymerize as a result of peroxide accumulation.
d These chemicals easily form peroxides and should probably be considered under part B.
e OSHA-regulated carcinogen
