First aid

General first aid measures. Get medical advice if you feel unwell

If inhaled
Respiratory support.
Skin contact
Compressed gases may create low temperatures when they expand rapidly. Leaks and uses that allow rapid expansion may cause a frostbite hazard. Wear appropriate personal protective clothing to prevent the skin from becoming frozen.
Eye contact
If eye tissue is frozen, seek medical attention immediately, if tissue is not frozen, immediately and thoroughly flush the eyes with large amounts of water for at least 15 minutes, occasionally lifting the lower and upper eyelids. If irritation, pain, swelling, lacrimation, or photophobia persist, get medical attention as soon as possible.

Handling, storage and disposal

Summaries only, follow the supplier SDS for your grade
