When installing new appliances, a kitchen without a gas interlock system will need to install one. If your kitchen installation is older than 2002, BS 6173:2020 recommends you have CO2 monitors installed. To notify when to increase the ventilation in the kitchen. Only CO2 monitors designed for use in a commercial kitchen should be used. Look for one with a PTFE filter that you can have changed easily.

Commercial kitchen regulations are BS6173:2020, IGEM UP19 and DW/172. BS6173:2020 specifies gas installations within commercial kitchens. It states gas should not be available within the commercial kitchen if the ventilation is not in operation, and this should be controlled by a gas interlock system. The interlock system must be CE marked. For more information HSE Gas Safety in catering and hospitality information sheet is available to download for free from the HSE website. IGEM UP/19 is a recommendation this goes further than BS6173:2020 and states that a carbon dioxide monitor should be installed when there is a variable speed controller to control the ventilation. This is because the end user can have all appliances on with the ventilation at low speed. The CO2 monitor should alarm at 2800 to alert that the ventilation needs to be increased. If ventilation is not increased once the CO2 levels reach 5000ppm the gas solenoid valve should close. DW/172 is the BESA specification for Kitchen Ventilation Systems and is acknowledged as the authoritative specification for kitchen ventilation design and installation for the UK.

A commercial kitchen gas safety interlock system is designed to shut off the gas if the mechanical ventilation in the kitchen fails. All commercial kitchens fitted out since 2002, in the UK must have a gas interlock installed. A pressure switch or current sensor is fitted to the extraction system and connected to the solenoid valve. If the system detects that the extractin system is working correctly the gas solenoid valve will allow you to use the gas appliances. Interlock systems also have a stop button that enables users to shut off the gas in an emergency.

Prices vary depending on the size of the gas pipework in the kitchen, the type of gas interlock required and if new pipework is necessary. For a free quotation contact us today.
