Maintenance Procedures - Propane Facility System Guidelines

1. Introduction

New requirements for the establishment of procedures for operations and maintenance of propane equipment were introduced in CSA B149.2-15 Propane Storage and Handling Code. Owners of propane facilities must develop and document operating procedures for day to day operation, emergency procedures, and maintenance procedures including testing, inspection, monitoring and repair of facility propane equipment.

2. Purpose 

The purpose of this manual is to provide facility owners and operators guidance and basic information to conform to Technical Safety BC’s requirements for the development, implementation and documentation of an operations and maintenance program which meets the intent and requirements for CSA B149.2-15 Clause 7.22 Operations and Maintenance Procedures.

3. Scope

The requirements for operations and maintenance procedures apply to the following propane facilities within the jurisdiction of the Gas Safety Regulation:

  • tank systems 
  • filling plants, 
  • container refill centers
  • dispensing systems
  • vaporizers and tank heaters
  • other equipment where liquid propane is piped to a process 

4. Definitions

Competency - the demonstrated ability to apply training, experience and knowledge in the execution of duties

Container refill centers – a facility, including a building, consisting of propane storage containers, piping and dispensing systems where liquid propane is transferred to containers

Dispensing systems - a system, consisting of tank, pump and motor, propane dispenser, and associated piping, for the storage, metering, and dispensing of liquid propane into containers or vehicle fuel containers

Filling plant – a facility for the distribution of liquid propane consisting of propane storage tanks and equipment for the transfer of liquid propane to or from rail cars, tank trucks or dispensing to containers or vehicle fuel containers

Tank heater - a form of vaporizer used to apply heat either directly to a portion of the container surface in contact with propane liquid or indirectly by circulating propane liquid from the container to the device and then back to the container

Tank system - a container or assembly of containers designed and fabricated in accordance with CSA B51 for the storage of propane including underground tanks

Vaporizer - a device for converting liquid propane to vapour by means other than atmospheric heat transfer through the surface of the container.

5. Owners and Operators Responsibility

Owners and operators of propane facilities shall develop and implement a management program that includes policies, processes and procedures for the operation and maintenance of the facility which:

  • Comply with the Safety Standards Act, Safety Standards General Regulation, Gas Safety Regulation and CSA B149.2
  • Set relevant company policies and performance objectives, 
  • Proactively identify hazards, evaluate risks, identify and implement risk mitigations measures, and conduct inspection, maintenance, and monitoring activities, 
  • Establish clear responsibilities and accountabilities, 
  • Provide sufficient trained and competent persons and other resources to manage the program and, 
  • Administer documentation, records reporting, evaluation and continual improvement. 

6. Management Program Requirements

The operation and maintenance management program shall incorporate the following facets and document the program’s policies, processes and procedures in a program management manual. As a minimum, each organization shall address the required facets relative to the size and complicity of the facility. Organizations shall explain their intent, capability and applicability for each facet outlined in this section. Work may be subcontracted provided controls are clearly defined for maintaining full responsibility for compliance with the Safety Standards Act, Safety Standards General Regulation, Gas Safety Regulation and CSA B149.2 by the facility owner/operator.

The management program manual should incorporate the following general requirements:

  • bound in a manner that allows for easy revisions and updating
  • company logo or letterhead on each page
  • typed name and date after a signature
  • typed  (handwriting not permitted)
  • each page must be identified with a page number, total number of pages in the manual and manual revision number and date

The manual should provide clear and simple instructions on the facility owner’s/operator’s policies and procedures for the management program.  The manual may be brief or detailed depending on the program requirements based on the size and complicity of the propane facility. Propane facilities in British Columbia, cover a broad range of installations from large filling plants with multiple propane storage tanks holding thousands of liters of propane and equipment for the transfer of liquid propane to or from rail cars, tank trucks to small commercial facilities consisting of a single tank, pump and propane dispenser for the storage, and dispensing of liquid propane into portable cylinders or motor vehicles.  

The extent of a program needed to achieve an effective and practical operation and maintenance program will therefore vary considerably and will also depend on the equipment that is at the facility. 

The level of documentation detailed in should be appropriate for the size, scope, complexity, and level of risk for an operation and may range from a few paragraphs for small operations consisting of a small amount of equipment with a low level of risk through to several pages for large, complex facilities or operations with numerous types and large numbers of equipment with a much higher level of risk. 

The following features are to be included in every manual:

  1. Title Page - The name and complete address of the facility owner/operator, the facility location, the number assigned to each “controlled” copy, the name of the person or group a controlled copy is issued and the date of issue shall be included on the title page of the manual.
