Where It Comes From
Industrial chemical used mainly as a precision‑cleaning solvent and in some specialty aerosol and maintenance applications; releases can occur from degreasing operations and equipment leaks [1][2].
How You Are Exposed
Mostly by breathing vapors at work during cleaning, maintenance, or handling; less commonly from indoor air in places where it’s used or near industrial sources [1][2].
Why It Matters
Ozone‑depleting substance and greenhouse gas under EPA regulation [1]. Short‑term exposure can cause headache, dizziness, drowsiness, and eye/skin irritation; very high levels can depress the central nervous system and cause unconsciousness [3].
Who Is at Risk
Workers in electronics/aerospace cleaning and similar shops, especially in poorly ventilated areas; people with heart or lung conditions may be more sensitive to solvent vapors [2][3].
How to Lower Your Exposure
Substitute safer cleaners; use closed systems and local exhaust; ensure good ventilation; follow EPA/employer controls; wear appropriate gloves/eye protection; review the Safety Data Sheet [1][3].
