PHYSICAL DATA

Completely miscible with water; pH >13; Density 0.9.



APPEARANCE & ODOR

Clear colorless liquid. Sharp odor of ammonia.



REACTIVITY & CONDITIONS TO AVOID

Stable at normal ambient temperatures. Ammonia evaporates from opened containers. Reacts

violently with strong acids, liberating heat. Incompatible with many oxidizers, halogens, and

silver salts.



FIRE HAZARDS

Ammonia released when heated will burn in air under some conditions. Not considered fire hazard.

Firefighters wear SCBA. Fumes are suffocating and corrosive. NFPA# 3-1-0.

HEALTH HAZARDS

Liquid and vapor are both severe eye irritant. High hazard through inhalation. LC 50 (inhl-rat)

2000 ppm/4 hr; Eye-rabbit 44 ug severe; LD 50 (oral-rat) 350 mg/kg. Symptoms of over exposure -

irritation of eyes, nose and throat. Coughing, suffocation, collapse. OSHA PEL (NH 3): 50 ppm;

ACGIH TLV (NH 3): 25 ppm TWA; 35 ppm (STEL). Investigated as a tumorigen and mutagen. No evidence

of carcinogenicity.



SPECIAL PRECAUTIONS

Wear goggles and rubber gloves while handling. Use only with proper respirator or adequate

ventilation.



FIRST AID

Wash skin and eyes thoroughly with water. For eyes, get further medical treatment.

Inhalation-remove to fresh air, if breathing is difficult give oxygen, if breathing stops use

artificial respiration. Mouth to mouth may not be effective as the lungs must be cleared of air

before breathing will begin. Call a physician or emergency medical squad. If swallowed, give

water to drink, ice to suck. Call a physician. Do not give anything by mouth to an unconscious

person.



SPILLS & LEAKS

Clear area of personnel. Ventilate thoroughly and wash up spill with water. A small amount of

dilute acid may help clear the fumes.
