Avoid ignition of gas clouds by removing ignition hazards,purging
or as a last resort
after carefull assessmentt-ignite gas,provided that flame
impingment will not occur on
the container to prevent widespread ignition danger and subsequent
Approach downwind to any fire or escaping product
Avoid coming in contact with gas or liquid, as:
