|FIRE & EXPLOSION
|Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting.
|NO contact with flammables. NO contact with reducing agents.
|In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water.
|Use ventilation, local exhaust or breathing protection.
|Fresh air, rest.
|Remove contaminated clothes.
|Wear safety goggles.
|First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
|CLASSIFICATION & LABELLING
|Ventilation. NEVER direct water jet on liquid. Personal protection: self-contained breathing apparatus.
According to UN GHS Criteria
|Fireproof if in building. Separated from combustible substances and reducing agents. Cool.
|PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance
|EXPOSURE & HEALTH EFFECTS
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS
|TLV: 10 ppm as TWA; BEI issued
|Density of the liquid at boiling point: 1.885 kg/l.
The odour warning when the exposure limit value is exceeded is insufficient.
Methemoglobinemia has been observed in animals, but relevance to humans is unclear.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Wear protective equipment during this operation.
Check oxygen content before entering area.
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
