100th CES tests unknown substances
Airman 1st Class Breanna Wallace, 100th Civil Engineer Squadron Emergency Management apprentice from Lostine, Ore., uses an alcohol swab to clean a handheld chemical and explosives identification tool during a hazardous materials hands-on training class June 6, 2013, at RAF Mildenhall, England. Service members were taught how to properly use the machine to ensure an accurate reading. The two-day training ensured RAF Mildenhall first responders and emergency responders are better equipped to quickly and effectively mitigate a hazardous material incident.
