Commercial kitchen gas safety checklist
A site record of a gas safety check in a commercial kitchen. Record the engineer, their Gas Safe number and catering competence, then the gas tightness test, emergency isolation, ventilation and the gas interlock, and the CO2 level if measured. Add each appliance with its flame supervision, flue or canopy, combustion, result, action taken, whether a warning notice was given, and photos. The form warns on interlock faults, counts appliances at risk or immediately dangerous, and records the next check date. Every question is listed below, and you can fill the live form in on this page.

What is checked in a commercial kitchen gas safety check?
A commercial catering gas check covers gas tightness, the emergency isolation valve, the mechanical ventilation and the interlock that shuts off the gas if the ventilation fails, and each appliance's flame supervision devices, flue or extract canopy and combustion. Regulation 35 of the Gas Safety (Installation and Use) Regulations 1998 requires employers to keep gas appliances, pipework and flues at work in a safe condition, and HSE's CAIS23 explains how this applies to catering.

Every question in the commercial kitchen gas check template
A commercial kitchen gas safety site record: each appliance checked, gas tightness, ventilation and the gas interlock, flues and flame supervision, emergency isolation, unsafe situations and the engineer's sign-off. 4 sections and 45 questions. Follow-up questions and guidance appear only when an answer calls for them, so the person on site never sees the ones that do not apply.

Commercial kitchen gas check FAQs
What is a gas interlock?
A system that shuts off the gas supply to the appliances if the mechanical ventilation fails. HSE's CAIS23 says manual bypasses are not permitted. The form warns if the interlock is faulty or not fitted.
Who can do the check?
HSE's CAIS23 says the business must be Gas Safe registered and its engineers must hold valid certificates of competence for the types of gas equipment and work involved. Ask to see the engineer's Gas Safe ID card.
How often should it be done?
HSE's CAIS23 says to follow the manufacturers' recommendations but, as a general rule, annual inspections are a reasonable minimum, with repairs as needed.
What if an appliance is unsafe?
The gas industry unsafe situations procedure (IGEM/G/11) applies. With the responsible person's permission, an at risk appliance is turned off and an immediately dangerous one is disconnected and sealed, a DANGER DO NOT USE label is attached, and a warning notice is completed. The form records the action and the notice.
Is this the gas safety certificate?
No. It is the engineer's site record. Issue the formal certificate or report from your own software.
Who uses this?
Commercial catering gas engineers, restaurant and pub operators, schools, care homes and contract caterers.
