Benzoyl chloride

Made in chemical plants as an intermediate for dyes, pharmaceuticals, resins, and perfumes; it rapidly breaks down in water to benzoic acid and hydrochloric acid [1].

Mostly at work by breathing vapors or getting liquid on skin/eyes; the public may be exposed during spills or fires near facilities [1][3].

Strong irritant/corrosive; can cause eye/skin burns, coughing, shortness of breath, and delayed fluid in the lungs; may increase cancer risk based on animal studies [1][2][3].

Chemical manufacturing and lab workers, transporters and emergency responders; people with asthma or lung disease; those living close to facilities using it [1][3].

Workers—use closed systems, local exhaust, and PPE (goggles/face shield, resistant gloves, respirator as needed) and get training; Community—follow emergency alerts, move upwind or shelter in place, and rinse skin/eyes with water and seek care if exposed [1][3].
