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).

Remove all ignition sources and water. Do NOT use water, sweep up the spill, place in a sealed bag or container, and dispose. Ventilate area and wash spill site after material pickup is complete. See Sections 8 and 13 for further information.

SECTION 7 &#; HANDLING AND STORAGE

Flinn Suggested Chemical Storage Pattern: Inorganic #5. Store with sulfides, phosphides, carbides and nitrides.
Store in a cool, dry place. Store in a Flinn Chem-Saf&#; bag and then inside a Flinn Saf-Stor&#; can. Use only in a hood or in a well ventilated area.

SECTION 8 &#; EXPOSURE CONTROLS, PERSONAL PROTECTION

Wear protective gloves, protective clothing, and eye protection (P280). Wash hands thoroughly after handling (P264). Use only in a hood or in a well ventilated area.

SECTION 9 &#; PHYSICAL AND CHEMICAL PROPERTIES

Rocklike, grayish-black. Odor of acetylene always present.
Garlic like odor.
Soluble: Reacts and decomposes with water.
Forms calcium hydroxide and acetylene with much heat.

Specific gravity: 2.22

SECTION 10 &#; STABILITY AND REACTIVITY

Decomposes in water to form acetylene and calcium hydroxide. Store in a metal can or a flammables cabinet. Avoid contact with water, acids, halogens, silver nitrate, copper compounds, and heavy metals.
Shelf life: Good, if stored under dry conditions.

TYPES OF
HAZARD/
EXPOSURE ACUTE HAZARDS/
SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING FIRE Not combustible but forms flammable gas on contact with water or damp air. Many reactions may cause fire or explosion.
NO contact with water.
Special powder, dry sand, NO other agents.
EXPLOSION Risk of fire and explosion on contact with water.
Use non-sparking handtools. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
