Identification of the substance or preparation
Chemical formula: CaC2
CAS No.: 75-20-7
EINECS: 200-848-3
Hazards identification
Cabide is a strong hygroscopic substance and is decomposed already in
the air. Through reaction with the water arises acetylene. Acetylene is
an explosive gas. Lower explosion limit is 1.5 % vol., upper explosion
limit is 80.5 % vol. Acetylene is a combustible gas with flash point of
305 C, with temperature class T 2, explosion group II.C. Impurities in
carbidic acetylene can show themselves toxic - PH3, H2S. Taking
concentration of calcium oxide (16.5%) in concideration, it has toxic
effects on the eyes and respiratory tract.
Attention is required before the opening of drum leakage of inerting gas acetylene with nitrogen injected into the holes of the caps Warning during drums decanting boundary carbide is required inerting with nitrogen inlet valve from the continuous
flow during decanting
