§ 13.101. Fuel engine generators for emergency lighting.

 (a)  Cylinders shall be installed above grade with an outlet at least 5 feet away from any building opening which is below the level of such outlet.

 (b)  A relief valve shall be installed on the low pressure side of the primary regulator adjusted to discharge into the atmosphere at a pressure less than the maximum allowable pressure for the engine regulator. Such discharge outlet shall be located not less than 5 feet horizontally from any opening into the building which is below such discharge.

 (c)  A solenoid operated valve shall be connected in the fuel line to the engine between the primary regulator and the engine regulator with the operating coil connected so that the valve will open automatically when the engine is in operation and be closed at all other times.

 (d)  The fuel line shall be of sufficient size to provide adequate fuel at satisfactory pressure to run the engine generator at rated connected load.

 (e)  An adequate fuel supply to operate the engine generator at rated load for 11/2 hours shall always be maintained. A gauge to indicate fuel level shall be provided.

 (f)  Cylinders or tanks shall be set on a firm foundation and in the case of school or other installations as deemed necessary by the Department shall be enclosed by a fence with locked gate to prevent unauthorized persons from tampering with the cylinders, tanks, regulators and other similar equipment.

 (g)  Fuel and fuel cylinder or tank for emergency lighting application shall be used for no other purpose.
