Trailer with 2 decontamination showers and 1 toilet
This trailer is designed to help protect firefighters by allowing them to shower directly at the incident location thereby decreasing the exposure time to harmful contaminants. The trailer contains two showers, each with two separate changing rooms and entrances. It also contains a vacuum toilet.
You start by taking off your contaminated clothes in the first changing room, after which you take a shower. When you are done, you move on to the next changing room and put on your clean clothes. By keeping the two changing rooms separate you eliminate further contact with the contaminants.
