Boron trifluoride

Chemical manufacturing and petroleum refining (polymerization/alkylation), resin and adhesive production, and laboratory synthesis; releases can occur from cylinders or transport incidents [1][3].

Mostly by breathing contaminated air at work or near an accidental release; contact with moist gas or resulting acids can injure eyes/skin. Public exposure is uncommon unless near industrial sites or transport accidents [1][2][3].

Short exposures can cause coughing, chest tightness, severe eye/skin burns, and life‑threatening lung fluid (pulmonary edema). Some effects may be delayed [1][2].

Chemical and refinery workers, maintenance crews, and emergency responders; people with asthma or other lung disease may be more sensitive [1][2].

At work, use closed systems, leak detection, and local exhaust; handle cylinders only if trained; wear appropriate PPE and follow monitoring/training requirements. In communities, know nearby facilities, sign up for alerts, and follow shelter‑in‑place or evacuation instructions during a release [1][2][3].
