|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 1000 ppm as TWA; A4 (not classifiable as a human carcinogen).
MAK: 5000 mg/m3, 1000 ppm; peak limitation category: II(2); pregnancy risk group: C
|Avoid release to the environment because of its impact on the ozone layer.|
|High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
