   1. (A) Dispenser Control Device (Actuators and Monitors) For Use by Customers to Activate Dispensing Equipment.

      1. 1. Devices may use keys or cards to acti-

vate dispenser and pumps. Coin or currency activated devices may be permitted upon approval by the director after a site safety assessment has been made.

coded, optically read or inductive coil cards to be inserted in a device to activate the pump.

1. 3. All dispenser control devices must

meet Underwriters’ Laboratory (UL) standards and shall be installed and maintained in accordance with the manufacturer’s instructions. All wiring shall comply with NFPA Manual No. 70, 1996 Edition.

1. 4. Motors of pumps to dispensing

devices shall not have electrical current supplied to them unless and until the dispensing device is activated by the insertion of the card or key device. The electric current to the motors of the pumps shall automatically terminate not more than three (3) minutes after the flow of product has ceased. Electrical current to the pump motors shall be off at all other times.

1. (10) The owner or operator of each unattended self-service station, upon reasonable request, shall make available person(s) and keys or cards, necessary to inspect and test all measuring devices.
2. (11) A container or storage shall be provided by the owner or operator of each device for the storage of the fuel dispensed during the device test. The container or storage shall comply with the requirements of NFPA Manual No. 30 entitled Flammable and Combustible Liquids Code, 1996 Edition.

3. (12) Dispensing devices, remote pumps and hose nozzle valves must comply with 2 CSR 90-30.080 and the following rules:

   1. (A) Hose nozzles must meet the standards of UL and—

      1. 1. Nozzles must be equipped with

devices designed to retain the nozzle spout in the vehicle fill pipe while refueling (for example, spout anchor spring). These devices must be in compliance with UL or Factory Mutual (FM). The spout anchor spring shall be of the type recommended by the manufacturer of the hose nozzle valve and installed and maintained in accordance with manufacturer’s recommendations;

1. 2. A listed automatic self-closing type

nozzle with a latch-open device must be installed as an integral part of the nozzle assembly with exception of marine installations which shall not have latch-open devices;

1. 3. Hose nozzle valves shall be of the

type which will close automatically, independent of the latch-open device, upon loss of pressure in the dispensing system and in which the latch-open device may only be engaged when the dispensing system is under pressure; and

1. 4. The nozzle must be designed and

maintained to cease the flow of product if the nozzle falls from the fill pipe of the motor vehicle being fueled.

1. (13) Remote pumps serving dispensing devices shall meet the standards of UL and 2 CSR 90-30

the requirements contained in 2 CSR 90- 30.050 (33).

1. (14) Dispensing devices shall meet the standards of UL and the following rules:

      1. 1. Be visible from all unattended self-

service dispensing device locations on the premises. If installation of a single switch or circuit breaker does not achieve compliance with the requirement, duplicate switches or circuit breakers shall be required;

1. 2. Terminate electric power to all dis-

pensers, pumps and dispenser control devices on the premises, including neutral conductors and low voltage control wiring; and

1. 3. Be of such a type, or installed in such
