Using brake cleaner containing tetrachloroethylene to clean metal before welding can produce phosgene gas when exposed to welding heat, which is highly toxic and can be fatal. Proper safety measures, including protective clothing, masks, and avoiding chemical misuse, are essential to prevent serious health risks.
A shelter-in-place order was issued for La Porte residents in Texas following a chemical leak at the ALTIVIA Chemical Complex. The leak released phosgene, a colorless gas with a suffocating odor, prompting officials to urge residents in the affected area to seek shelter. The order was lifted after the company contained the release, and there were no detectable amounts of hazardous products near the facility. There was no impact on local schools, and those with non-emergency medical concerns related to the incident were advised to contact the non-emergency line. ALTIVIA Chemical Complex is a producer of phosgene derivative intermediates and operates a large production facility for phenol, acetone, and alpha-methyl styrene.
