Authorities in North Brunswick, New Jersey, responded to a hazardous materials incident on Thursday morning, July 16, 2026, after a chlorine spill at an LA Fitness gym injured seven people and forced a full evacuation. The emergency began shortly before 7:00 a.m. when gym patrons and staff reported a strong chlorine-like odor and respiratory irritation. Firefighters, led by Fire Chief Leo Whalen, detected a heavy chlorine odor on arrival and ordered an immediate evacuation. A tanker truck delivering liquid chlorine for the gym’s indoor pool reportedly released a significant amount of chemical due to a mechanical or procedural failure, prompting a major hazmat response.
