Exposure Controls/Personal Protection

Personal Protection

Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.

Respirators

A NIOSH/MSHA approved air purifying dust or mist respirator or European Standard EN 149.

Exposure Effects

Orthostatic abnormally low blood pressure and rapid heart rate are common. Abnormally low blood pressure and low heart rate are possible. Throbbing headache is common. Seizures have been reported following severe intoxication. Behavioral deficits were observed in the adult offspring of rats who received sodium nitrite prenatally.

Exposure limit(s)

OSHA PEL: 15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance dusts.
