Abstract: A portable emergency unit comprises an eyewash and shower station coupled to a chassis. A water tank and a pump are coupled to the chassis and are in fluid communication with the eyewash and shower station so that the pump is operable to supply water from the water tank to the eyewash and shower station when the eyewash and shower station is activated. A temperature control system is also coupled to the chassis and is in fluid communication with the water tank. The temperature control system is operable to maintain the temperature of water stored in the water tank within a predetermined range.
