What are the risks of fire and explosion from calcium carbide?
This produces
highly flammable and explosive acetylene
gas (ICSC 0089). This generates fire and explosion hazard. Reacts with chlorine, bromine, iodine, hydrogen chloride, lead, fluoride magnesium, sodium peroxide and sulfur. This generates fire and explosion hazard.
