Several apparent suicide deaths related to mixing common household chemicals have been reported by local media in the past year. This alarming news follows on the heels of 517 suicide deaths reported in Japan throughout 2008 attributed to inhaling hydrogen sulfide gas created by mixing household detergents. In 2009, one incident in San Jose, CA resulted in a hazardous materials lockdown of the hospital, diversion of incoming ambulances, and decontamination of nearly 100 persons that included rescuers.

Ad hoc internet sites are felt to be responsible for disseminating harmful information related to mixing chemical products for this purpose. While there is no cause for widespread panic, symptoms can mimic carbon monoxide poisoning and EMS responders are encouraged to approach any closed, suspicious vehicle with extreme caution.
