Directive: Hydrogen regulation under the Gas Safety Regulation and Power Engineers, Boiler, Pressure Vessel and Refrigeration Safety Regulation

Reference number
D-B6 050728 2

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

General details

This Directive is being issued to stakeholders to clarify the demarcation points for when the Gas Safety Regulation (GSR) or the Power Engineers, Boiler, Pressure  Vessel  and  Refrigeration Safety Regulation (PEBPVRSR) apply with respect to hydrogen and equipment used in respect of hydrogen. In the latest iteration of the  GSR (BC Reg., 103/2004), the definition of “gas” was changed from the   past and now includes, at section 2,  hydrogen. This change may cause confusion for some  stakeholders with respect to the regulation of hydrogen under the PEBPVRSR that was in place prior to the change in the GSR definition.  The intention of  including hydrogen in the GSR definition is to  provide that the GSR applies with respect to hydrogen in new fuel cell technologies as well as  supporting infrastructure such as vehicle refuelling stations.

Specific details

Application of the Gas Safety Regulation to hydrogen

The use of hydrogen for fuel cells is new but hydrogen has long been used in industrial applications.  The practises for the storage and utilization of hydrogen in industrial processing and production applications are well established and are covered by the pressure vessel and piping standards adopted under the PEBPVRSR.  These established industrial applications of hydrogen with ASME storage vessels and piping systems are therefore better suited to continued regulation under the PEBPVRSR. The revision to the GSR is not intended to include this type of use. Instead, the inclusion of hydrogen in the definition of gas is intended to apply only where hydroge n is being generated, stored or used as a fuel for fuel cells and associated support systems or equipment such as internal combustion engines.

Accordingly, it is hereby directed that the GSR applies with respect to hydrogen only where hydrogen is, or is intended to be, generated, stored or used as a fuel for fuel cells and their associated support systems or combustion equipment such as internal combustion engines.

A new hydrogen installation code for use with new fuel cell and associated technologies is currently under development. It is anticipated that, when complete, this code will be adopted under the GSR to cover the installation of hydrogen fuel cells and their support equipment.
