Emergency Shelter Trailers are temporary shelters designed in a mobile form for emergencies. They use either wheel systems or modular frames to move swiftly to areas struck by a disaster. Depending on the plan, these building units might include beds, bathrooms, kitchens, electricity, and air conditioning. These include tents only for one night, to large installations meant for continuous living, or to act as command posts. Because of how versatile they are, they are used for housing as well as for hospitals, messaging centers, offices, and even schools during long-term emergencies.
