Toxicity
The material is very toxic (Rating 4 according to "Clinical
Toxicology of Commercial Products"). The probable lethal dose
(to humans) is 50 to 500 mg/kg of body mass.
TWA OEL-R
ST OEL-RL
: 17 mg/m3 or 25 p.p.m. as NH3
: 24 mg/m3 or 35 p.p.m. as NH3
(According to "Occupational Health and Safety Act", Act 85 of
1993, as amended.)
1.4
Hazards
THE MATERIAL IS UNDER PRESSURE.
The material causes severe burns to the skin and is extremely
irritating to the eyes and respiratory tract. The vapour is
poisonous and may cause pulmonary oedema. It is a moderate
fire hazard, and it forms explosive mixtures at concentrations of
16 to 27 % (v/v) in air. Brief exposure at 5 000 p.p.m. may cause
rapid death due to suffocation or fluid in the lungs.
1.5
Special Precautions
Avoid ingestion, inhalation, contact with the skin and eyes. Wear
full protective clothing when handling the material and ensure
adequate ventilation. Avoid sources of ignition and heat. Storage
tanks must be earthed for protection against lightning or static
electricity. Care must be exercised when opening the valves.
