Every fuel oil pipe emanating from any fuel oil tank,
which, if damaged, would allow fuel oil to escape from the tank, is to be provided with a
positive closing valve directly on the tank. The valve is not to be of cast iron, although the use
of nodular cast iron is permissible, see 4-6-2/3.1.4. The positive closing valve is to be
provided with means of closure both locally and from a readily accessible and safe position
outside of the space. In the event that the capacity of the tank is less than 500 liters (132 US
gallons), this remote means of closure may be omitted. |
