The Gas Safe regulations demand that all commercial kitchens are legally required to have a gas interlock system fitted.

What is a Gas Interlock System?

These devices provide a failsafe that helps maintain kitchen safety and reduces the risk of an accident. A gas interlock system restricts the flow of gas to any appliances until the ventilation system is on and working correctly.

In this way the gas interlock system can prevent the build-up of carbon monoxide and nitrogen dioxide that present a significant threat to employee health. The interlock system is also designed to prevent explosions caused by a build-up of unburned gas.

A sensor built into the gas interlock system monitors airflow. Where there is none, or the flow is insufficient, the gas flow remains cut off. With the gas supply cut off, kitchen equipment cannot be used until the airflow improves.

Who needs a Gas Interlock System?

Ultimately, any business operating a commercial kitchen must have a gas interlock system fitted to meet British Standard BS6173 and the Gas Safe regulations. Failure to have a gas interlock system fitted could result in:

  • Unacceptable health and safety risks to employees and the general public.
  • Prosecution by the Health and Safety Executive.
  • Closure of the kitchen until safety systems have been installed.
  • Other fines that could threaten the financial future of your business.
  • Gas Safety inspection failure

As such, it is imperative that any business operating a kitchen has a gas interlock system fitted.
