§5573. Fuel Dispensing Units.

(a) Class I liquids shall be transferred from tanks by means of fixed pumps designed and equipped to allow control of the flow and prevent leakage or accidental discharge.

(b) Only listed nozzles may be used for dispensing Class I liquids. No such nozzle may be used if it shows evidence of having been dismantled.

EXCEPTION: Nozzles which are an integral part of a gasoline vapor recovery system, certified by the State Air Resources Board and the State Fire Marshal pursuant to the provisions of Sections 41954 through 41961, inclusive, of the California Health and Safety Codes.

(c) Every dispensing nozzle for Class I liquids installed after December 31, 1978, shall contain evidence of listing so placed that any attempt to dismantle the nozzle will result in damage to such evidence, visible without disassembly or dismounting of the nozzle.

EXCEPTION: Nozzles which are an integral part of a gasoline vapor recovery system, certified by the State Air Resources Board and the State Fire Marshal pursuant to the provisions of Sections 41954 through 41961, inclusive, of the California Health and Safety Codes.

NOTE: A rebuilt nozzle valve shall be deemed in substantial compliance with (b) and (c) if:

(1) The nozzle valve has been approved, within the meaning of Section 3206; or

(2) The user of the nozzle valve shows a certificate prepared by the rebuilder which certifies that:

(A) The nozzle valve:

1. Has a spout that will break off at 150 pounds or less;

2. Will shut off automatically when dropped from a height of 22 inches to a concrete floor;

3. Has been pressure tested to 10 psi;

4. Has a poppet seat that has been pressure tested to 50 psi.

5. Will shut off automatically at a minimum flow rate of 5 gallons per minute; and

6. Can be reasonably expected to operate without malfunctioning due to mechanical failure in excess of 100,000 cycles under laboratory conditions; and

(B) The rebuilder of the nozzle valve has made application to a nationally recognized testing laboratory to obtain a listing in accordance with the Occupational Safety and Health Act of 1970.

(d) A control shall be provided that will permit the pump to operate only when a dispensing nozzle is removed from its bracket or normal position with respect to the dispensing unit, and the switch on this dispensing unit is manually actuated. This control shall also stop the pump when all nozzles have been returned, either to their brackets or to the normal non-dispensing position.

(e) Class I liquids shall not be dispensed by applying pressure to drums, barrels and similar containers. Approved pumps taking suction through the top of the container or approved self-closing faucets shall be used.

(f) The dispensing unit and its piping, except those attached to containers, shall be mounted on a concrete island or protected against collision damage by suitable means. If located indoors, the dispenser shall also be mounted either on a concrete island or protected against collision damage by suitable means and shall be located in a position where it cannot be struck by a vehicle that is out of control descending a ramp or other slope.
