Sodium acetate is widely used in de-icer products, especially at airports, and its supercooling properties allow it to be used in heat pad products. It is used in dyeing processes as a mordant, as a retarder for some elastomers, and in tanning to enable better penetration of the tan.
It is also used as a buffer in petroleum production, and for kidney dialysis processes.

If the fumes are inhaled, give the victim access to fresh air, and seek medical attention in the event of even slight breathing difficulty.
If ingested, give the victim several glasses of water, but seek medical advice if a large amount (more than say 25 grams) are swallowed.
Skin contact should be treated by removing contaminated clothing and footwear, and thoroughly rinsing the affected area. If irritation persists, seek professional medical help.
