yes. it's the boy who cried wolf. one building may have some asbestos fibers in the interior of its walls, used as, say pipe insulation many decades ago. the asbestos is contained and does not enter the air. another building, say, an auto body repair shop, may have organic solvent vapors floating around at a relatively high concentration on a daily basis. both have the prop 65 warning. which one should i prefer to work in? (the real answer is i don't know and i don't care because, like most Californians, i don't pay any attention to those signs. i don't even know what they mean. it's all noise to me. i think i'll have two bags of potato chips on my lunch break today.)
