Users of the Code are advised that the change markers in the text are not intended to be all-inclusive and are provided as a convenience only; such markers cannot constitute a comprehensive guide to the revisions made to the Code.

Care must therefore be taken not to rely on the change markers to determine the current requirements of the Code. As always, users of the Code must consider the entire Code and any local amendments. Aerosol container — a non-refillable container meeting the requirements for 2P, 2Q, or 2R aerosol containers for containment and transportation of propane under the Transportation of Dangerous Goods Regulations of Transport Canada.

Connected for use — a propane container that is properly connected to an appliance in accordance with the provisions of this Code. Construction site — a temporary worksite involving construction activities such as the erection, alteration, and dismantling or demolition of a building or equipment, re-roofing of a building, or digging. Container with respect to propane storage — either an aerosol container, a cylinder, or a tank. Dispensing system — a system, consisting of tank, pump and motor, propane dispenser, and associated piping and supports, for the storage, metering, and dispensing of liquid propane into containers.

Propane dispenser — an assembly intended to dispense liquid propane and controlled by a human operator. The assembly can include a pressure relief device, vapour separator, strainer, metering assembly, meter register mechanical or electronic , control valves, hose, hose nozzle, controls mechanical or electronic , interlocking mechanism, locking mechanism, weigh scale, and associated wiring, piping fittings, and housing.

Tank with respect to propane storage — the class of container for the storage of propane, designed and fabricated in accordance with CSA B Vaporizer — a device for converting liquid propane to vapour by means other than atmospheric heat transfer through the surface of the container.

Vehicle fuel dispenser — a propane dispenser, specifically for dispensing liquid propane by volume into containers. Note: The Transportation of Dangerous Goods Regulations impose additional restrictions on the selection and use of cylinders. Except as permitted by the requirements of CSA B, when steel equipment is installed on the container and the container has been used with anhydrous ammonia, it may be used for propane if purged in accordance with Clause A.

This seal shall be in place whenever the cylinder is not connected for use. Table 6. No more than one cabinet may be located against a combustible wall. Each cabinet shall contain no more than lb kg of propane. Cabinets shall be 3 ft 0. Cabinets shall be 25 ft 7. The fencing or storage cabinet required by Clause 6. On an automated cylinder exchange machine, the vending system shall not be capable of returning to automatic operation after a manual override until the system has been inspected and reset by authorized personnel.

A cylinder properly connected for use in an approved manner is not considered in storage. The following requirements shall apply: a When the following conditions are met, a storage area utilizing a structure with overhead protection, walls, or both, meets the intent of outdoor storage: i The structure is designed to be enclosed by no more than two solid walls on the level the cylinder s are stored.

These signs shall be in accordance with Clause 7. The excess-flow valve shall be either integral to the cylinder valve or in the connection with the cylinder valve outlet. In either case, it shall be installed in such a manner that undue strain beyond the excess-flow valve will not cause breakage between the cylinder and the valve; d the cylinder-regulating equipment and manifold are not located where they are subject to damage; e when repair work is being carried out in a building not under construction and occupied, any cylinder used in the repair work is under the supervision of the operator at all times; f each cylinder is provided with a protective collar; g a cylinder with a capacity up to and including lb 45 kg of propane that is connected for use to a construction heater is secured in an upright position; and h any construction heater connected to the cylinder is installed and used in accordance with Clause 7.

When moving a propane cylinder to or from the roof or one level to another of a building, each cylinder valve outlet shall be closed and plugged, and the valve protective cap or collar shall be in place.

See also Clause 6. In either case, it shall be installed in such a manner that undue strain beyond the excess-flow valve will not cause breakage between the cylinder and the valve.

Additional non-refillable cylinders manufactured to Specifications TCM and aerosol containers up to an equivalent of L approximately cylinders may be stored inside the restaurant or non-residential food service location, if stored inside an approved ULC-C or UL cabinet.

Vertical containers used in liquid service shall not be manifolded to horizontal containers. Vertical containers of different dimensions shall not be manifolded together. To accommodate electrical system grounding to the pump, either a polarization cell shall be provided or the pump shall be dielectrically isolated from the tank and piping.

Note: Non-metallic tubing installed between metallic piping and an underground tank is acceptable as a dielectric joint. The area of ventilation openings shall be at least equal to the combined discharge areas of the pressure relief devices and other vent devices or lines that discharge into the dome, housing, or curb box.

Not more than one such manifold system may be located against a common wall of a building unless separated by a distance of 10 ft 3 m ; and b when the single largest container in a manifolded system is allowed in Clause 7. The largest single container in the manifolded system shall be used to determine the clearances required in Table 7. Table 7. Each opening shall have an opening to floor area ratio of not less than These ventilation openings shall be not less than 10 ft 3 m horizontally from any air intake of any appliance or air-moving equipment or any other opening into any building; c have floor at or above grade.

Any space below a floor shall be well ventilated and kept free of combustible material or the space shall be filled in with tamped earth; d have two or more exits when the travel distance to an exit is more than 15 ft 4. The type of explosion relief venting shall be one of the following: i an open area; ii an outwardly opening sash; iii an explosion-relief panel; or iv single-strength glass; and f have all pressure relief valve discharges vented to the exterior, and shall not be within 3 ft 0.
