Uses of Nitrogen Trifluoride

• an oxidiser for high-energy fuels and is used in chemicalsynthesis

• a fluorine source for the hydrogen fluoride anddeuterium fluoride high-energy chemical lasers

Potential hazard • Inhalation causes breathing

difficulties, chest pains, and nausea. It forms a hemoglobin complex, similar to carbon monoxide, and thus, is highly poisonous due to interference with oxygen transport in blood.
