What to Do If You Smell Natural Gas Near Your Home

A natural gas odor requires immediate attention. The smell is often compared with rotten eggs because suppliers add an odorant to otherwise odorless gas. Even a faint sulfur-like odor can signal a leak from an appliance, service line, meter, or underground utility.

Your first priority is to get people and pets away from the possible source. Do not try to identify the leak, repair equipment, or determine whether the smell is “strong enough” to report. A small leak can create a dangerous atmosphere when gas accumulates in an enclosed space.

Recognize The Warning Signs

The clearest warning sign is a sulfur or rotten-egg smell inside or near your property. You may also hear hissing near a gas appliance, meter, pipe, or damaged service line. Blowing dust, bubbling water, dying vegetation, or an unusual gas odor outdoors can indicate a leak in an underground line.

Physical symptoms can include dizziness, headache, nausea, weakness, or confusion. These symptoms may result from poor air quality or oxygen displacement. Anyone who feels unwell should move into fresh air immediately and receive medical attention when necessary.

Act Immediately Indoors

If you smell gas inside, tell everyone to leave at once. Do not turn lights on or off, operate appliances, use a doorbell, light a candle, start a vehicle in an attached garage, or use a phone while inside the building. Electrical switches and motors can create a spark that ignites accumulated gas.

Leave doors and windows as they are unless one can be opened while exiting without delay or touching an electrical control. Do not search for the leak or attempt to shut off the gas supply unless the valve is immediately accessible and you have been instructed on its operation. Evacuation is more important than protecting property.

Move Away And Report The Leak

Once you are outside and safely away from the odor, call 911 if there is a strong smell, a suspected major leak, fire, explosion risk, or anyone experiencing symptoms. Contact the appropriate gas utility emergency line from a safe location and explain where the odor was detected. Do not assume someone else has reported it.

Stay clear of the building, meter, damaged utility line, and any area where gas may be collecting. Keep neighbors, children, and pets away. Do not return indoors until emergency responders or the gas utility says it is safe, even if the odor seems to have disappeared.

Situation	Immediate action	Avoid
Gas odor inside a home	Leave immediately and warn others while exiting	Lights, switches, appliances, flames, and indoor phone calls
Odor near a meter or outdoor pipe	Move away, keep people back, and report it	Touching the meter, smoking, or starting a vehicle nearby
Odor near street excavation or infrastructure	Leave the area and notify emergency services or the utility	Entering the work zone or approaching damaged lines
Someone feels dizzy or sick	Get into fresh air and call for medical assistance	Re-entering the suspected leak area
The odor stops after ventilation or wind	Continue treating it as a possible leak and report it	Assuming the problem has corrected itself

Respond To An Outdoor Gas Odor

A natural gas smell outdoors can come from a household connection, underground distribution pipe, construction damage, or another nearby source. Move crosswind or upwind if possible, increasing your distance from the odor without walking toward equipment or a visible leak.

Avoid flames, cigarettes, vehicles, power tools, and anything that could produce a spark. Do not cover a damaged line, dig near it, or use water to investigate bubbling soil or pavement. If the smell is near a roadway or public facility, keep away from traffic and notify emergency personnel from a safe location.

Protect Your Home Before An Emergency

Know which appliances use natural gas and teach household members how to recognize the odor. Keep emergency contact details accessible outside the home, such as in a mobile phone kept away from the suspected leak area or on a printed household safety card. Make sure children understand that they should leave immediately and tell an adult rather than investigate.

Have heating systems, water heaters, fireplaces, and other gas appliances inspected and maintained by qualified professionals. Never use a gas appliance for a purpose it was not designed for, and never operate a damaged appliance. Carbon monoxide alarms provide an important additional safeguard, but they do not detect natural gas leaks and cannot replace leak response.

Use Local Infrastructure Information

Municipal services and utility operations can involve streets, excavation, meters, public rights-of-way, and other infrastructure. The Susanville Public Works website provides official information about city services and helps residents find relevant contacts, utility resources, safety information, and public works updates.

For an immediate emergency, call 911 rather than waiting for office hours or submitting a routine service request. When reporting, provide the location, the strength of the odor, whether anyone is ill, and whether you see flames, damaged pavement, exposed piping, or construction activity. Give responders clear landmarks while remaining at a safe distance.

Build A Household Safety Routine

A simple plan reduces hesitation during a gas emergency:

• Teach every household member to leave first and call from a safe location.
• Keep 911 and the local gas utility emergency number readily available.
• Arrange a meeting point well away from the home, meter, and suspected leak.
• Schedule professional maintenance for gas appliances and heating equipment.
• Report unusual odors near streets, sidewalks, excavation areas, or utility infrastructure.

Do not rely on smell alone. Odor strength can vary, wind can disperse gas, and some people may have a reduced ability to detect the odorant. Treat any unexplained natural gas odor seriously, evacuate without creating sparks, and contact emergency services or the utility from a safe location. Acting quickly can protect your household, neighbors, and public infrastructure.
