Smell Gas? An Action Checklist
Get familiar with M2 Property’s action checklist so you know what to do if you smell gas.
Gas leaks can be dangerous and cause serious harm. If you smell gas—often described as rotten eggs or sulphur—act immediately. Stay calm, move fast, and never ignore it.
Checklist
1) Ventilate
- Open all doors and windows to disperse gas
- Do not turn on extractor fans or use anything electrical
2) Evacuate
- Leave the building by the nearest safe exit
- Help others if safe to do so
- Stay outside and upwind of the property
3) Report
- From outside, call National Gas Emergency Service: 0800 111 999 (free, 24/7)
- If you’re in immediate danger, call 999 and request the Fire Service
4) Do Not
- Use matches, lighters or smoke
- Turn light switches or electrical devices on/off
- Re-enter the building until professionals say it’s safe
5) Notify
- Inform your block or property manager once emergency services have been called
- Let neighbours know to stay clear
6) Prevention
- Arrange annual Gas Safety checks (CP12 certificate)
- Fit a carbon monoxide alarm near boilers or gas heaters
