Gas Interlock Systems

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?

Also known as a gas safety 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.

Gas Interlock System maintenance

Gas interlock systems require regular routine maintenance to ensure that they are functioning correctly in line with BS6173 standard. Failure to maintain systems could lead to operational issues that prevent the kitchen working properly.

More importantly still, your gas interlock system needs to be routinely checked to ensure that it is functioning as specified. Your gas safety devices need to be checked at least once a year to verify that airflow detection and gas cut off perform as expected.

A qualified engineer will need to check each operating component of the system is working efficiently, including valves, sensors and pipework.

Who can work with Gas Interlock Systems?

Gas interlock systems can only be installed and repaired by F GAS 2079-certified engineers to meet the Gas Safe regulations. It is also illegal for anyone who is not Gas Safe registered to carry out any work on a gas interlock system. Always ensure that any subcontractor hired to maintain your gas interlock systems is suitably qualified.

Gas Safety Inspections

You probably already know that under the Gas Safety (Installation and Use) Regulations 1998 you have a legal duty to make sure that any gas equipment on your premises is checked and certified by a Gas Safe qualified engineer once every year.

Commercial kitchens need a gas safety inspection by a gas registered company in order to make sure that every appliance is certified safe for use, keeping catering premises safe and efficient for everyone.

What is a Gas Safety certificate?

Commercial Gas Safety Inspection (non-domestic) is the official name for a safety certificate that is issued annually by a registered Gas Safe engineer to cover all installation and appliances in your kitchen.

The inspection should include all gas appliances, pipework, extraction systems and gas interlock systems. The inspection will make sure that all details are covered, for example that the canopy has the correct overhand, that the CO & CO2 levels are not too high and that there are no gas leaks on any catering appliance.

The list of safety checks is set down by law and, because they are vitally important, you will need to prove that you are up to date with your checks for insurance purposes. If anything should happen to your premises, failure to obtain an up-to-date Gas Safety Certificate and keep a copy on the premises will probably invalidate your insurance policy.

If you don’t have an up-to-date Gas Safety Certificate then not only are you potentially uninsured and putting the health and safety of your employees and customers at risk, but you could also find yourself being prosecuted under Regulation 35 of the “Duties of Employers and self-employed persons” of the Gas Safety (Installation and Use) Regulations.

Who needs a Gas Safety Certificate?

The law places duties on the responsible person (employer) to ensure that gas appliances, installations, pipe works or flues are maintained in a safe condition. If your premises are leased, your landlord also has a duty to ensure that all appliances and flues are checked by a Gas Safe registered engineer. Also, he or she must supply you with a copy of the gas safety record within 28 days of the inspection, so that you can keep it on the premises.

If you’re not sure whose responsibility the gas certificate is in your case then check your lease, as there will quite likely be a clause transferring responsibility for the certificate to you.

How often do I need one?

You need to have your premises inspected and a new certificate issued every 12 months by law.

"Excellent service! We had a fairly substantial leak coming through our kitchen floor and MHM Services were able to come and diagnose the problem the same day and returned the next day to complete the work. The work was completed promptly, left tidy afterwards and all for a very reasonable price. We will definitely be using MHM Services again."
