Where It Comes From
Made and used in chemical manufacturing as a solvent/intermediate; found in some labs and old medical stocks; releases can occur during production, use, spills, or improper storage [1][2].
How You Are Exposed
Breathing vapors at work; skin or eye contact with liquid or mist; accidental swallowing; indoor air from leaking containers [1].
Why It Matters
Irritates eyes, nose, and throat; can cause headache, dizziness, nausea, and drowsiness—high levels may lead to unconsciousness; repeated skin contact may cause dermatitis. It is highly flammable [1].
Who Is at Risk
Workers in chemical plants, labs, and healthcare settings; people with asthma or other breathing problems; anyone in poorly ventilated spaces [1].
How to Lower Your Exposure
Use in well-ventilated areas or fume hoods; wear chemical-resistant gloves and eye protection; keep containers sealed and away from heat; follow safety data sheets and workplace rules; if you notice a strong odor, leave and ventilate; dispose of old stocks properly [1][2].
