Also, could you please list the MSDS info for each Copper and Sulfur.
It depends on the state in which it is encountered: solid, flakes, powder, wire etc. According to the MSDS I found on the Sigma-Aldrich website, copper wire has no associated warning pictograms. Copper powder, however, is classified as highly flammable and very toxic for the environment. Sulphur powder and flakes are listed as irritants only. OELV levels for copper wire and powder are listed as 0.2 mg/m? for an 8-hour day, whereas sulphur powder or flakes do not have an occupational exposure limit. The LD50 for copper powder, however, is 3.5 mg/kg, whereas the LD50 for sulphur is well over 2,000 mg/kg. So copper is more toxic than sulphur. I'd say copper is the more hazardous element, but the more volatile and toxic sulphur oxides are a greater risk during a fire.
