We have found in our experience, that there are many different policies for the upkeep of fire department equipment. Some departments perform upkeep one compartment per week. Others may complete the whole truck in a months time. Some departments perform these duties as often as they utilize the equipment on a call. If it isn't used, it doesn't get serviced. At our department, we completely remove every piece of equipment, one compartment at a time, and clean and check for serviceability, every Thursday. The entire apparatus is cleaned inside and out, to include the engine compartment. If a tool fails inspection, it is fixed or removed from service. How is this duty performed at your respective department or company?
