Swimming Pool Chemicals: Emergency Response
- Emergency Response is available in Portable Document Format (PDF, 200KB)
A Rockland County homeowner mixed calcium hypochlorite (pool shock treatment) and hydrochloric acid in an aluminum pan in the kitchen of his home. The chemicals reacted and produced hydrogen and chlorine gas, resulting in an explosion. The explosion blew out a window and sent two adults to the hospital with breathing problems. Four firefighters required decontamination at the scene. The homeowner was advised not to re-enter the home until a hazmat contractor could be hired to complete the cleanup.
