Who this guide is for

- Anyone who wants basic gas-safety awareness.
- People preparing to involve qualified gas professionals.
- Readers who want awareness, never instructions.
If you suspect gas — treat it as an emergency
This is the most important section. A suspected gas leak is an emergency. This guide does not tell you how to handle gas — only that you should treat suspicion seriously and get expert help immediately.
- Do not use electrical switches, flames or anything that could ignite.
- Follow the recognised emergency steps for your area.
- Leave the building and get to fresh air.
- Contact your gas emergency service / qualified professionals.
Know your gas appliances and shutoff (awareness)
As a planning matter, it helps to know what is gas-powered and where the main shutoff is — as awareness, not as a prompt to do gas work.
- Identify gas appliances (cooker, boiler, fire, water heater).
- Know where the main gas shutoff is located.
- Note appliances near planned work.
- Keep emergency contact details accessible.
Ventilation and appliances as topics
Gas appliances and ventilation are discussed together for safety. Note context for professionals; do not adjust anything yourself.
- Whether gas appliances have adequate ventilation (a professional topic).
- Any soot, staining or unusual smells around appliances.
- Appliances that may be moved or affected by work.
- When appliances were last professionally serviced.
Plan qualified involvement
All gas work is for qualified, registered professionals. Plan their involvement before any work near gas.
- Engage qualified, registered gas professionals for any gas work.
- Schedule their involvement before disturbing appliances or lines.
- Confirm local registration requirements.
- Document appliance locations for your contractor.
