Universal Citation: ID Admin Code 16.02.14.240

Current through September 2, 2024

01. Feeder. Pools must be equipped with a disinfectant feeder or feeders that meet the following requirements. Equipment must be:

a. Capable of being easily disassembled for cleaning or repair and be constructed of corrosion-resistant materials;

b. Constructed to permit repeated adjustments without loss of output rate accuracy and be constructed to minimize stoppage from debris that may be contained in aid chemicals used;

c. Designed specifically for the type of disinfectant used; and

d. Provided with controls for adjusting the flow rate of disinfectant.

02. Backflow Prevention. When the disinfectant is introduced at the suction side of the pump, a device or method must be provided to prevent air lock of the pump or recirculation system.

03. Chlorine Gas Equipment. When compressed chlorine gas is used, the following additional features must be provided:

a. Chlorine rooms must have a ventilating fan with an airtight duct beginning near the floor and terminating at a safe point of discharge to the outdoors, away from any occupied area or any fresh air intake. A louvered air intake must be provided near the ceiling. The ventilating fan must provide one (1) air change per minute and operate from a switch located outside the door.

b. Chlorinator equipment must be designed to withstand wear without developing leaks.

c. Chlorine cylinders must be anchored in an upright position to prevent falling over. A valve stem wrench must be maintained on the chlorine cylinder so the supply can be shut off quickly in the case of an emergency. Empty chlorine gas cylinders must be tagged as such. Full and empty gas cylinders must be stored only in the chlorine room and have protective hoods in place when not in use.

d. A new washer or gasket approved for use on chlorine gas must be used each time a chlorine cylinder is connected to the chlorinator. Spare washers/gaskets must be kept on site.

e. A self-contained breathing apparatus designed for use in a chlorine atmosphere must be provided, and be located in an area outside the chlorination room easily accessible to pool employees.

f. An automatic chlorine leak detector or commercial twenty-six (26) degrees Baume Aqua Ammonia must be provided for chlorine gas leak detection.

g. Installation of chlorinator equipment, and operation thereof, must be carried out by or under the supervision of personnel trained in the installation and operation of such equipment.

04. Hypochlorite Equipment. When a hypochlorite solution is fed through hypochlorinator equipment, such equipment must also provide the following additional features:

a. Positive feed under all conditions of pressure in the circulating system, without artificial constriction of the pump suction line whether this line is under vacuum or pressure head;

b. Constant feed with varying supply or back pressure;

c. Prevent backflow from the circulation system to the solution container; and

d. Prevent siphoning of hypochlorite solution when recirculation pump and hypochlorinator are both turned off.
