1-Bromo-1-(bromomethyl)-1,3-propanedicarbonitrile

Produced in chemical manufacturing; releases can occur during production, transport, or spills. Not expected from everyday consumer use [1][2].

Mostly at work by inhaling vapors/aerosols or through skin/eye contact. People near facilities could be exposed if there’s an industrial release to air or water [2][4].

Specific toxicity data are limited, but available information indicates it can irritate eyes, skin, and the respiratory tract; avoid ingestion or high exposure [2].

Workers who make, use, or transport it; emergency responders; residents near manufacturing sites during a spill or release [4].

At work, use closed systems, local exhaust, protective gloves/eye protection, and follow the Safety Data Sheet and NIOSH’s hierarchy of controls [3]. In the community, follow emergency instructions, avoid visible plumes/odors, and use alternative water until officials say it’s safe after a spill [4].
