If containers are involved in a fire, safely relocate or keep cool with water spray. Persons in ill health where such illness would be aggravated by exposure to nitrogen should not be allowed to work with or handle this product.

Caution when entering contaminated areas to ventilate to acceptable oxygen levels.
