Liquefied Petroleum Gases Bulk Storage Regulations (C.R.C., c. 1152)

40 (1) Hose and hose connections subject to container pressure shall be designed to have a bursting pressure not less than five times the maximum working pressure to which they may be subjected.

(2) The hose as assembled for use shall be tested for leaks at twice the maximum working pressure to which it may be subjected before being put into service and should be tested annually thereafter at 1 1/2 times the maximum working pressure.

(3) The hose shall be clearly and permanently marked or labelled “L.P. Gas” together with maximum working pressure, manufacturer’s name or symbol, and year of manufacture.

(4) Hose and hose connections shall be resistant to the action of liquefied petroleum gas under the service conditions to which they are subjected.

(5) Testing procedures as prescribed by the Underwriters’ Laboratories, Inc. Pamphlet Hose for Conducting L.P. Gas are recommended.

(6) Hose and hose connections located on the low pressure side of regulators or reducing valves shall be designed for a working pressure of not less than 125 psig and in no case less than five times the pressure setting of the safety relief devices protecting the system.

(7) Flexible hose connections to appliances shall be as prescribed in the current edition of National Fire Protection Association Pamphlet No. 58.

(8) Where hose is to be used for transferring liquid, wet hose is recommended.  Such hose shall be equipped with a shut-off valve on the discharge end and provision shall be made to prevent excessive hydrostatic pressure in the hose.

(9) The use of hose is prohibited for inter-connecting stationary containers.
