Where It Comes From
Vehicle coolants/antifreeze, de-icing fluids, some brake fluids, and in making polyester resins [1][3].
How You Are Exposed
Mainly by swallowing (accidental or intentional); less often by breathing mists at work or through skin contact with liquid or vapor [1][2].
Why It Matters
Breaks down in the body to acids that can cause nausea, confusion, metabolic acidosis, and serious kidney damage or failure; can be fatal [1][3].
Who Is at Risk
Children and pets around garages, people who store or decant antifreeze at home, auto/aircraft maintenance workers, and anyone using non-beverage alcohol substitutes [1][2].
How to Lower Your Exposure
Store products in original, child-resistant containers; keep locked away; clean spills promptly; never put into drink bottles; maintain vehicles to prevent leaks; at work, use gloves/eye protection and ventilation as recommended on safety data sheets [1][2]. Where appropriate, consider propylene glycol–based antifreeze, which is less toxic if swallowed [1].
