 We just got word about a chemical storage facility where two employees went missing, they're still punched in and they're suspected hazardous materials inside so we're about to enter the building. We're checking the door to see if it's hot. Once we get inside we do a 360 sweep of the room. So we came back and we sampled the powder and the two liquid jars. Once we identify the hazards and we know what we have downrange then we're clear to take the casualty out through the decontamination line to get them in medical.
