When a registered engineer identifies an unsafe situation there’s a procedure they will look to follow - the Gas Industry Unsafe Situations Procedure (GIUSP):
Warning Label and Unsafe Categories
If a registered engineer has identified a gas related danger in your home, they’ll attach a Danger Do Not Use warning label to the dangerous gas fitting and provide you with a warning notice. The warning notice will provide details of the unsafe situation. There are two types of unsafe categories:
Immediately Dangerous (ID):
If an installation is classified as ‘immediately dangerous’ it is considered to be an immediate danger to life and property if left operating. The installation will be disconnected with your permission, and cannot be used until remedial work has been carried out to repair the defect(s). Continuing to use an immediately dangerous appliance could endanger lives.
Should you refuse them permission to disconnect the installation or appliance and the appliance runs on natural gas, the gas engineer will report the situation to the Gas Emergency Service Provider (ESP). The ESP has legal powers of entry to make the situation safe, and are also able to disconnect the gas supply to the property. However, this does not apply to Liquefied Petroleum Gas (LPG) installations.
At Risk (AR):
If an installation is classified as ‘At Risk’ there are one or more recognised faults present which could constitute a danger to life or property without further faults developing. The installation will be turned off with your permission, and should not be used again until the fault has been corrected. There are a limited number of cases in which turning off the gas supply will not remove or reduce the risk. In such circumstances, you’ll be issued with a warning notice and advised on who to contact for further investigation.
You may be advised that the installation does not comply to current standards. While this is something to bear in mind, it’s up to you if you choose to act on it. It’s always a good idea to bring an installation up to date, but whether you’d like this done could depend on external factors such as cost or whether you’ll be looking to have the appliance replaced in the near future.
If the Gas Emergency Service Provider has been out to your property as a result of an emergency visit (such as a smell of gas or fumes) and cannot confirm that an appliance is safe, they may also attach a ‘Danger Do Not Use’ warning label to the installation/appliance and issue you with an appropriate warning notice.
If the ESP has issued you with one of these notices, you’ll be advised not to use the appliance until an appropriately qualified Gas Safe registered engineer has checked it. It is the homeowner’s responsibility to ensure the installation is checked. The registered engineer should keep you (or your landlord where appropriate) informed of the actions they’re taking in the interests of your safety.
