Gas Interlock systems are recognised as an essential safety aspect of all modern Commercial kitchens. The Basic function of a gas interlock system is to supply gas to the appliances when it has been proved that the ventilation system is functioning.
IGEM/UP/19 "Design and application of interlock devices and associated systems used with gas appliance installations in commercial catering establishments" gives guidance on the requirements of Gas Interlock systems, as required by GSIUR Gas Safety (Installation and Use) Regulations 1998.
All new kitchen installations must have a gas interlock installed in conjunction with a ventilation system, designed and manufactured to the specifications outlined in DW172 "Specification for Kitchen Ventilation Systems"
Any installation that contains a Type B appliance (eg combination oven) must have a gas interlock system installed.
Existing kitchen installations do not necessarily require a gas interlock system installing if the Atmospheric testing for CO2 indicates adequate ventilation. IGEM/UP/19 does recommend however that installation of a system would improve safety and therefore should be considered in the near future, along with ventilation system improvements in line with DW172.
After completing a CO2 atmospheric test, your catering engineer may recommend the installation of a Gas Interlock system in accordance with GSUIR and IGEM/UP/19. There are some different additions and/or functions that may be recommended.
