What should I do if I smell gas in my home?
A rotten-egg or sulphur-like odour near gas equipment may indicate a fuel-gas leak and requires immediate evacuation.
Urgency: emergency
What this means
Do not operate switches, phones, flames, vehicles, or appliances inside; leave and call from outside.
Safe checks
- Warn others without using electrical devices
- leave doors as found
- move away from the building
- call the gas emergency line or 911.
Stop and get help if
- Do not investigate, shut internal valves, relight equipment, or return until the utility or fire service declares it safe.
Which professional to call
Contact the matched licensed or qualified trade if safe checks do not resolve the issue.
