Hazardous Combustion Products: Carbon monoxide can be
produced when primary air and secondary air are deficient while
combustion is taking place.
Fire and Explosive Hazards: Explosive air-vapour
mixtures may form if allowed to leak to atmosphere.
Sensitivity to Impact: No
Sensitivity to Static Discharge: Yes
Fire Extinguishing Precautions: Use water spray to cool
exposed cylinders or tanks. Do not extinguish fire unless the
source of the escaping gas that is fueling the fire can be turned
off. Fire can be extinguished with carbon dioxide and/or dry
chemical (BC). Container metal shells require cooling with water
to prevent flame impingement and the weakening of metal.
If sufficient water is not available to protect the container shell
from weakening, the area will be required to be evacuated.
If gas has not ignited, liquid or vapour may be dispersed by
