​Recently the Texas A&M Engineering Extension Service (TEEX) partnered with Southwest Research Institute (SwRI) and the Alcohol Tobacco Firearms and Explosives Agency ​(ATF) to quantify First Responder exposure to Li battery emergencies.  Multiple batteries were forced into thermal runaway and the products of combustion were measured.  Multiple types of First Responder Personal Protective Equipment (PPE) were expose and cleaned utilizing NFPA 1851 water-based cleaning methods along with liquid CO2 techniques.  This presentation will explain contaminates (SVOC, PAH and Heavy Metals) associated with Li battery fires, along with the effectiveness of PPE cleaning techniques.
