Where It Comes From
Older airbag inflators, lab reagents/preservatives, and some industrial uses; spills or poor disposal can release it to air or water [1][3].
How You Are Exposed
Breathing dust or hydrazoic acid gas near spills, skin contact, or swallowing contaminated solutions; highest risk is at workplaces that make or use it [1][2][3].
Why It Matters
Can cause low blood pressure, headache, dizziness, nausea, shortness of breath; high doses: seizures, collapse, death; also irritates eyes/skin. Not known to cause cancer in people [1][2].
Who Is at Risk
Workers handling azide (labs, manufacturing, wastewater), first responders, and people near confined, poorly ventilated spaces; those with heart or breathing problems may be more sensitive [1][2][3].
How to Lower Your Exposure
Do not handle azide unless trained. Keep acids away from azide solutions and drains. If exposed: go to fresh air, remove contaminated clothing, rinse skin/eyes 15 min, and call Poison Control (1-800-222-1222) [2][3].
