Where It Comes From
Manufactured for nitration processes and specialty research; releases can occur from chemical production, labs, or spills [2][3].
How You Are Exposed
Breathing vapors at work, skin contact with liquid or contaminated surfaces, or nearby air during industrial use or an accidental release. It can be absorbed through the skin [2][3].
Why It Matters
Strong irritant that can cause coughing, shortness of breath, and delayed lung injury; may also affect the blood, liver, and nervous system. IARC: possibly carcinogenic (Group 2B) [1][2].
Who Is at Risk
Workers in chemical manufacturing and nitration operations, research labs, maintenance/cleanup crews, and emergency responders; people near an industrial spill or fire [2][3].
How to Lower Your Exposure
Use closed systems and local exhaust; wear chemical-resistant gloves, eye/face protection, and respirators as directed; monitor air and follow spill procedures. In communities, heed official advisories, stay upwind/indoors during incidents, and follow evacuation orders if issued [2][3].
