Trichloroacetyl chloride

Produced in chemical plants as an intermediate; not intended for consumer use [1][3].

Mostly at work (manufacturing or labs) via vapors or splashes; nearby communities may be exposed during spills or fires [1][2].

Causes severe skin and eye burns; inhalation irritates the nose and lungs and can lead to fluid in the lungs; reacts with water to release hydrogen chloride (acid) fumes [1][2][3].

Chemical manufacturing workers, lab staff, maintenance/tank cleaners, and first responders; people with asthma or lung disease may be more sensitive [2][3].

At work, use closed systems, fume hoods, and proper PPE (acid-resistant gloves, goggles/face shield; respirators as needed); store away from water; have spill/eyewash plans. Public: follow emergency instructions and avoid smoke or fumes during incidents [1][2][3].
