SECTION 4 — FIRST AID MEASURES
Immediately call a POISON CENTER or physician (P310).
If inhaled: Remove victim to fresh air and keep at rest in a position comfortable for breathing (P304+P340).
If in eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do so. Continue rinsing (P305+P351+P338).
If on skin or hair: Immediately remove all contaminated clothing. Rinse skin with water (P303+P361+P353).
If swallowed: Rinse mouth. Do NOT induce vomiting (P301+P330+P331).
SECTION 5 — FIRE FIGHTING MEASURES
Flammable solid. Exposure to water or moisture evolves flammable acetylene. 500 g of calcium
carbide will yield approximately 150L of flammable acetylene.
In case of fire: Use a tri-class dry chemical fire extinguisher (P370+P378).
