Where It Comes From
Made and used as a monomer and crosslinker for polyethylenimine, paper and textile treatments, adhesives, and ion‑exchange resins; releases can occur during production, use, storage, and spills [3][4].
How You Are Exposed
Mainly by breathing vapors at work or through skin/eye contact; the public may be exposed near facilities or during transport accidents [3][4].
Why It Matters
Causes severe eye, skin, and respiratory burns; headache, nausea, and lung injury can occur. It is mutagenic and classified as possibly carcinogenic (IARC 2B) and reasonably anticipated to be a human carcinogen (NTP) [1][2][4].
Who Is at Risk
Workers who make or use it; lab staff; maintenance and emergency responders; people with asthma or skin conditions may be more sensitive to irritation [3][4].
How to Lower Your Exposure
Use closed systems and local exhaust; wear chemical‑resistant gloves, goggles/face shield, and appropriate respiratory protection; follow spill plans. Communities should follow incident alerts and stay upwind/indoors during releases; seek medical care after significant exposure [3][4].
