*See California Fire Code for amendments *NFPA 13D, Amended Sections as follows: Revise Section 6.2.2 to read as follows: 6.2.2 Where a well, pump, tank or combination thereof is the source of supply for a fire sprinkler system , the configuration for the system shall be one of the following:

(1) The water supply shall serve both domestic and fire sprinkler systems,

( a ) A test connection shall be provided downstream of the pump that creates a flow of water equal to the smallest sprinkler on the system. The connection shall return water to the tank. (b) Any disconnecting means for the pump shall be approved. (c) A method for refilling the tank shall be piped to the tank. (d) A method of seeing the water level in the tank shall be provided without having to open the tank. (e) The pump shall not be permitted to sit directly on the floor. (2) A stand-alone tank is permitted if the following conditions are met:

(a) The pump shall be connected to a 220-volt circuit breaker shared with a common household appliance (e.g., range, oven, dryer), (b) The pump shall be a stainless steel 240-volt pump, (c) A valve shall be provided to exercise the pump. The discharge of the exercise valve shall drain to the tank, and (d) A sign shall be provided stating “Valve must be opened monthly for 5 minutes.” (e) A means for automatically refilling the tank level, so that the tank capacity will meet the required water supply duration in minutes, shall be provided. (f) A test connection shall be provided downstream of the pump that creates a flow of water equal to the smallest sprinkler on the system. The connection may return water to the tank. (g) Any disconnecting means for the pump shall be approved. (h) A method for refilling the tank shall be piped to the tank. (i) A method of seeing the water level in the tank shall be provided without having to open the tank. (j) The pump shall not be permitted to sit directly on the floor. Add new Section 6.2.2.1 to read as follows: 6.2.2.1 Where a fire sprinkler system is supplied by a stored water source with an automatically operated means of pressurizing the system other than an electric pump, the water supply may serve the sprinkler system only. Add new Section 6.2.4 to read as follows: 6.2.4 Where a water supply serves both domestic and fire sprinkler systems, 5 gpm (19 L/min) shall be added to the sprinkler sys- tem demand at the point where the systems are connected, to determine the size of common piping and the size of the total water supply requirements where no provision is made to prevent flow into the domestic water system upon operation of a sprinkler. For multipurpose piping systems, the 5 gpm (19 L/min) demand shall be added at the domestic connection nearest the design area. This demand may be split between two domestic connections at 2.5 gpm (10 L/min) each.

APPENDIX AF

RADON CONTROL METHODS

The provisions contained in this appendix are not mandatory unless specifically adopted by a state agency or referenced in the adopting ordinance.

User note:

About this appendix: Appendix AF contains provisions that are intended to mitigate the transfer of radon gases from the soil into dwelling units. Radon is a radioactive gas that has been identified as a cancer-causing agent. Radon comes from the natural breakdown of uranium in soil, rock and water.
