Gas Smell Protocol
If you smell gas in your home, evacuate immediately and call 911 and your gas utility—no exceptions.
Natural gas typically carries an odorant that smells like rotten eggs or sulfur. If you detect it—even faintly—open no windows, turn off no lights, and avoid any sparks: no light switches, appliances, phones, or garage door openers. Exit the building immediately, taking pets and family members with you, and move upwind if possible. Once outside and at a safe distance, call 911 first, then your gas utility's emergency number. Wait for emergency responders to declare the area safe before reentering.
Never attempt to find the source of the leak yourself. Even small leaks near appliances, meters, or underground lines can build explosive concentrations quickly, especially in tightly sealed older homes. Ventilation won’t prevent ignition, and ignition sources are harder to spot than you think—static electricity from removing synthetic clothing or stepping on carpet can trigger an explosion. Professionals use specialized equipment to locate and repair leaks safely.
After the incident is resolved, schedule a licensed plumber or HVAC technician to inspect all gas appliances and connections before resuming use. Have your boiler, water heater, and stove checked—Especially if they’re older or weren’t installed to code. Keep a copy of your gas utility’s emergency number posted near your stove or by the front door. If you’re in a multi-family building, alert your property manager right away—others may be at risk too.
