(A) The disinfection system shall be designed and installed to minimize all hazards to health, safety, and welfare. Gas chlorinators and chlorine gas cylinders shall be housed in an enclosure separated by a tight partition wall from the swimming pool, corridors, dressing rooms and other space used by bathers. The floor of the enclosure shall not be below the grade surrounding the enclosure. Heat sources shall not pose any hazard to the gas chlorinators and chlorine gas cylinders. In the room where the chlorine gas is stored, a door to the outside shall be provided with a sign posted on the outside of the door noting use of chlorine gas within. The device feeding gaseous disinfectants shall not be readily accessible to any public room. Such room shall be provided with an air intake and exhaust ventilation system to remove contaminated air and replace with fresh air. The exhaust fan intake shall be located near the floor level and the fan shall cause four complete air changes per minute and discharge directly to the outside air.
(B) Emergency pull chains which activate the exhaust fans and shut down the comfort ventilation system on the premises shall be installed and located outside of and near the entrance to the chlorine room. An automatic alarm or public address system shall be provided to expedite evacuation in case of a chlorine gas emergency.
(C) Chlorine cylinders shall be secured so that they cannot fall. A valve stem wrench (no longer than six inches on ton containers) shall be maintained on the chlorine cylinder at all times so the supply can be quickly shut off in case of an emergency. The valve protection hood shall be kept in place except when the chlorine cylinder is connected. The chlorine feeding device shall be designed so that during accident or interruption in the water supply, leaking chlorine gas will be vented to the outside of the building in a safe manner.
(D) Respiratory protection apparatus designed for use in a chlorine atmosphere approved by the National Institute of Occupational Safety and Health shall be provided at each location or given to each employee. Each individual employee's apparatus must have been properly fitted and adjusted and plainly marked with the employee's name. Replacement canisters for apparatus shall be provided, and a service record shall be maintained. Use of respiratory protection shall conform to Occupational Health and Safety Regulations. The respirator apparatus shall be located outside of the room where the chlorinator is housed and shall be easily accessible for use.
(E) Corrosives and oxidizers shall be stored and used in a manner which prevents chemical reactions. Organic chemicals shall be stored separate from inorganic chemicals. All chemicals shall be stored off the floor in a clean, dry location, in their original, closed containers and away from heat sources. Chemical containers shall not be stacked on top of each other in an unsafe manner.
