This awareness course will alert search and rescue personnel to growing suicide trends started in Japan that use an extremely poisonous gas (hydrogen sulfide) as the means of ending life. These chemical suicides are initiated by using common household cleaning products to cause the chemical reaction that produces hydrogen sulfide. Search and rescue personnel need to recognize the signs and symptoms of a chemical suicide and be familiar with the resources available to properly assess the incident as well as process the scene for investigative purposes.  This program will include recognition, identification, response, rescue, and recovery as well as review a number of case studies of recent incidents.  In many cases the victim posts signs or banners on the vehicle or inside the building warning first responder of the dangers.  In others cases, no warning signs have been posted and without the proper training first responders can easily become a victim.  In a number of cases, first responders have become victims of an acute exposure to this toxic gas because they were unaware of the dangers and the victims did not post any signs.
