Section XIV-623 - Safety DevicesA. Shower Temperature Control Devices.1. Multiple (gang) Showers. Multiple (gang) showers, when supplied by a single temperature controlled water supply pipe, shall be controlled by a master temperature actuated mixing valve conforming to ASSE 1069, or each shower shall be individually controlled by an automatic compensating scald preventative valve of the pressure balancing, thermostatic or combination pressure balance/thermostatic mixing valve type conforming to ASSE 1016, ASME A 112.18.1 or CSA B125.1. Handle position stops or other limit setting devices shall be provided on such valves and shall be adjusted in accordance with manufacturer's instructions at time of installation to deliver a maximum mixed water outlet temperature of 120°F (48.3° C).2. Individual Shower and Shower/Bath Combinations. Shower and shower/bath combinations in all buildings shall be provided with an automatic compensating scald preventative valve of the pressure balance, thermostatic, or combination pressure balance/thermostatic mixing valve type which provides scald and thermal shock protection for the rated flow rate of the installed showerhead. These valves shall conform to ASSE 1016, ASME A 112.18.1 or CSA B125.1 and shall be equipped with a means to limit the maximum setting of the valve to 120°F (48.3°C), which shall be field adjusted in accordance with the manufacturer's instructions at the time of installation.B. Public Lavatory Temperature Control Devices. The temperature of the water delivered from public use lavatories or other public hand-washing fixtures shall be limited to a maximum temperature of 120°F (48.3° C) by a temperature control device that conforms to ASSE 1070.C. Bathtub and Whirlpool Temperature Control Devices. The temperature of the water delivered from bathtubs and whirlpools shall be limited to a maximum temperature of 120°F (48.3° C) by a temperature control device that conforms to ASSE 1070, except where such protection is otherwise provided for in accordance with §623. A of this code. Table 623 Temperature Control Device Standards |

D. Thermal Expansion Control. Thermal expansion shall be controlled in accord with the following requirements. 1. If water is heated and stored in a consumer's system and the system has been closed by the installation of a backflow preventer or a pressure reducing valve, a thermal expansion control shall be installed at an accessible location between the checking device and the water heating equipment to limit thermal expansion of the water being heated to not more than 80 psi (552 kPa) static pressure at any fixture on the system. A potable water expansion tank or auxiliary relief valve set at 80 psi (552 kPa) shall be acceptable.2. The auxiliary relief valve shall be in addition to the water heater safety relief valve. This thermal expansion control device shall be designed and trimmed for repeated operation. The valve shall be a minimum 1/2-inch pipe size, shall be adjustable and calibrated, and shall include a tag describing its function.La. Admin. Code tit. 51, § XIV-623
