The chemical odorant mercaptan, which smells similar to rotten eggs, is added to natural gas for your protection so that you can tell when the gas is present.
Be aware that the source of a gas odor could be inside your home/business or external – gas leaks in service lines or street mains can migrate into your home or business. In addition to the smell of gas, other signs to watch for include:
Blowing dirt, bubbling water, ice formation, or an unusual area of distressed or dead vegetation on the ground above where a pipeline is located;
Hissing sound near a pipeline, or in or around a building.
Also, if your pilot light or burner is substantially higher than normal, this may be an indicator of excessive gas pressure.
If you smell gas, suspect a gas leak, or notice excessive gas pressure contact the City’s Emergency Utility Service at 513.785.7550 – available 24 hours a day, 7 days a week – or call 911.
Observe the following safety precautions:
Ventilate the building by opening doors and windows.
Evacuate the building immediately and warn others to leave or stay out.
Do not turn on or off any electrical appliances or electronic equipment as you leave; even a light switch or cell phone can create a spark, which could ignite the gas.
Do not smoke or use lighters or matches.
From another location, call the City’s Emergency Utility Service at 513.785.7550 – ANYTIME DAY OR NIGHT – or call 911.
