What to Do Before Making the Call
SCDF advises turning off the stove and gas controls and opening doors and windows to ventilate. Do that only if they are immediately accessible and you can do so safely without delaying your exit. If the smell is strong, the source is unclear or getting to a control would mean going back into the affected area, leave and call for help from a safe distance. Use the operator’s instructions for what happens next. SCDF Civil Defence Emergency Handbook
Keep ignition sources away
An electrical switch can create a spark when operated in either direction. Leave lights, fans, extractors and other switches as they are. Avoid using a phone in the affected area and keep cigarettes and open flames away. Use your voice to tell anyone nearby to move away if you can do so safely. SCDF Civil Defence Emergency Handbook
Piped Gas, LPG and a Smell in a Shared Space
Piped town gas
Use City Energy’s emergency line for suspected leakage. If you are calling from a safe place outside the flat, tell the operator whether the smell seemed to be in the kitchen, near a meter or in a shared corridor. Give what you observed and say if you are unsure where it began. City Energy emergency hotline · EMA gas leak guidance
Bottled LPG
Call the authorised cylinder supplier from safety. Keep the supplier’s official number somewhere household members can reach without going back to the cylinder. If the installation is in a shop or food stall, tell staff responsible for the premises once you are clear of the area. SCDF Civil Defence Emergency Handbook
A common corridor, restaurant or school canteen
Move away and tell building or venue staff from safety. Say where the smell is strongest if you already know. Leave inspection and isolation to the people responsible. If there is fire or anyone is in immediate danger, call 995. SCDF emergency services
What to Say When You Report It
“I smell gas at [address]. We first noticed it near [location] at [time]. We are now at [safe location]. The supply is [piped gas, cylinder or unknown].” Tell them if someone is still inside or unwell. If building access is controlled, say which gate responders can use and follow directions about where to wait.
After the Immediate Risk
Wait for the responsible service or responders to tell you it is safe to return or use the gas supply. City Energy says turning on piped town gas is handled by City Energy or its appointed agents. It also directs households to City Energy or a Licensed Gas Service Worker for gas installation work. If a leak is suspected during renovation, stop work, move away and report it.
