Developed by: Energy & Utility Skills
Approved on: 30 Mar 2020


This standard is about dealing with gas emergencies.  It is for the industrial part of the non-residential downstream gas industry.  It can apply to gas emergencies for any type of fuel gas or combinations of fuel gas.   

It includes identifying the spread, complexity and risk of emergency situations, acting to reduce risk when it is safe to do so, instigating gas escape emergency  plans, managing isolation and evacuation procedures and maintaining communications with all appropriate people.  Any person carrying out this role must have site specific competence relevant to the level of risk.

This standard is for the person in charge of gas escape emergencies in non-residential downstream, industrial properties.
