The storage facility that houses pool chemicals must have adequate ventilation, according to the Centers for Disease Control (CDC). Separate air-handling systems should be installed for the pump room and chemical storage. Separate air-handling systems should also be in place for the area around the pool and the rest of the building.
Storage facilities that house pool chemicals must be built according to local building codes or they should follow the guidelines set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Older storage facilities that do not have separate air-handling systems for the chemical storage area, pool area and pump room should install emergency heating, ventilating and air conditioning cutoffs.
Storing pool chemicals in a storage room or pump room requires that adequate ventilation is in place. The CDC states that storage facilities that house pool chemicals should be ventilated to the outside. Pool chemicals should never be stored with herbicides, grease or gasoline to reduce fire hazards and the release of toxic vapors.
