Revision Number
Revision 1

This Directive is being issued by a provincial safety manager pursuant to section 30 of the Safety Standards Act.

General details

This Directive details Technical Safety BC gas approval/certification requirements for Mobile Outdoor Food Service Units (MOFSU) with walls on all four sides and a permanent roof; constructed, imported, or operated, in British Columbia.

Excluded from this directive: other outdoor appliances, hot dog carts, and trailers, these shall be certified by an accredited certification agency (body) when included in the scope of a standard.


  1. From CSA B149.1-Natural gas and propane installation code: 

Approved - acceptable to the authority having jurisdiction.

Certified - (with respect to any appliance, accessory, component, equipment, or manufacturer’s installation instructions) - investigated and identified by a designated testing organization as conforming to recognized standards, requirements, or accepted test reports.

Mobile outdoor food service unit (MOFSU) - a unit used outdoors for preparation and dispensing of food or beverages and that contains appliances or equipment operated by propane in the vapour state. The unit can be equipped with wheels and its own motive power.

  1. 2.     From the Safety Standards Act:

Certification mark - means a stamp, mark, seal, label, tag or other identification of a certification agency certifying that the regulated product to which it is affixed or attached or in which it is embedded meets the standard that the product must meet for that certification.

  1. From the Gas Safety Regulation

Certification agency (body) - An organization accredited by the Standards Council of Canada under the Standards Council of Canada Act as an organization engaged in conformity assessment is a certification agency for the purposes of this regulation.

Specific details

All MOFSU’s must bear one of the following:

a. Technical Safety BC Record of Installation Permit (ROIP) decal affixed by a gas safety officer following a physical on-site assessment;

b.Technical Safety BC gas approval decal issued under S.10 of the Safety Standards Act

c. certification mark from a certification body accredited by the Standards Council of Canada (SCC) or:

d. approval label from an inspection body accredited by the SCC.

Note: As the bodies listed in (c) and (d) must be nationally accredited, their decal or mark is acceptable in British Columbia, irrespective of the manufacturing location.

An appliance, accessory, component, or equipment utilized in the gas system of a MOFSU must be approved, and installed in accordance with the manufacturer’s certified instructions and the referenced code(s) and/or standard(s).

If a MOSFU is connected to a separate, external container exceeding 100 lbs. capacity, or a fixed fuel source (e.g. natural gas meter), a commercial “piping only” permit must be obtained by a licensed gas contractor prior to connecting. If the additional container is replacing an on-board fuel supply, then the following will be required as applicable:

 i. The installation shall comply with B149.1 and B149.2 code requirements

 ii. Container(s) integral to the unit are to be capped or plugged to prevent accidental release of propane, or entry of debris into container outlet(s)

iii. The first-stage or integral two-stage regulator is to be connected above the external container’s highest possible liquid level to prevent reliquification of propane vapour in accordance with B149.1 clause 5.1.2.The supply pigtail or whip is to be oriented to allow drainage of reliquified propane back to container

iv. If the external propane supply is removed, the system is to be returned to its original configuration and tested for integrity by a qualified gasfitter.

Where a MOFSU does not bear a certification mark, approval label, or British Columbia ROIP, an owner may engage a Technical Safety BC licenced gas contractor to confirm compliance with the appropriate code(s) or standard(s) and obtain a commercial installation permit. A separate permit application is required for each MOFSU, the permit fee will be based on the total BTU input of all appliances contained in the unit, entered as a single appliance. The application must also include a list of all gas appliances, and their serial numbers.

Upon completion, the gas contractor must contact Technical Safety BC and arrange for a physical on site assessment by a gas safety officer. An ROIP decal will be affixed by the safety officer once compliance is confirmed.

Modification of a gas system, after the original approval or certification, requires a new permit to be obtained, the unit to be re-inspected and a new decal applied.

It is the responsibility of the owner or operator to ensure that their MOFSU meets any other regulatory requirements such as: electrical, plumbing, fire service, local health authority and local government bylaw or licensing requirements.

Applicable codes and standards:

An accredited certification body may decal any unit type when included in the scope of a standard. These to be constructed to and conforming with applicable sections of either ANSI Z21.58-2015, CSA 1.6-2015 “Outdoor Cooking Gas Appliances”, ANSI Z83.11-2016 or CSA 1.8-2016 “Gas Food Service Equipment”.

An accredited inspection body may decal a unit constructed to, and complying with, relevant sections of the CAN/CSA B149.1 Natural gas and propane installation code, the CAN/CSA B149.2 Propane storage and handling code and the B149.5 Installation code for propane fuel systems and containers on motor vehicles.

The Standards Council of Canada maintains a list of accredited bodies on their website: SCC Accredited Bodies.

MOSFU gas systems are not to be constructed to the CSA Z240.4.2 Recreational Vehicle Standard. A recreational vehicle which has been converted and had its vehicle gas system modified is no longer approved, and must be approved or certified as detailed above.
