Start by confirming the interruption schedule and restoration plan with your local gas utility. Then prepare for any loss of gas-powered heat, hot water, or cooking—and do not turn a shutoff meter back on or relight appliances unless your utility specifically instructs you to do so.
Confirm what the utility plans to interrupt
Read the notice and contact the utility using the number or account details on it. Ask what service or appliances are affected, when the interruption is expected to begin and end, how updates will be shared, and how you will know service has been restored. The reviewed guidance from Enbridge Gas and National Grid describes different access and restoration practices; your local utility’s instructions govern.
- Will all gas service be interrupted, or only service to particular equipment?
- Does a technician need access to your home or meter? If so, when, and must an adult be present?
- What should you do if nobody is home when restoration work is scheduled?
- How will the utility provide schedule changes and confirm restoration?
Keep your utility account contact information current so you can receive updates. National Grid specifically asks its customers to keep the account phone number updated for outage communication; this is not a universal utility requirement.
Plan for heat, hot water, and cooking
Identify which household needs depend on gas and plan alternatives for the expected timing and conditions. If gas provides space heating, consider how you will keep household members and pets safe and whether you may need to stay elsewhere. Plan separately for hot water and cooking. Follow the instructions for any temporary heating or cooking equipment, and use it only in the manner and location its manufacturer and safety guidance allow.

Never use a gas stovetop or oven to heat your home. Ready.gov warns that doing so can create carbon monoxide and fire hazards (Ready.gov power outage guidance).
Consider needs that may make an interruption harder to manage, such as medication, mobility or accessibility, infants, older adults, and pets. If your home cannot remain safe without gas service, arrange a suitable place to stay rather than relying on an unsafe heating or cooking method.
Rank #2

Gather practical supplies
Keep basic supplies accessible for the interruption. Enbridge’s emergency-kit guidance includes water, food, a flashlight, and batteries (Enbridge Gas emergency guidance). Add items based on your household’s needs and the utility’s expected schedule; there is no universal kit or duration established for planned gas work.
- Water and ready-to-eat food, as appropriate for your household
- A battery-operated flashlight and spare batteries
- Any household-specific essentials you may need if the interruption lasts longer than expected
A carbon monoxide alarm is important in homes with fuel-burning appliances, but it does not detect a natural gas leak. Enbridge recommends CO alarms on every level of a home; do not treat an alarm as a substitute for recognizing and responding to a suspected gas leak.
Rank #3
- Combustible Gas Leak Detector: PT177 is a useful little tool that helps every household with gas appliances to quickly and easily pinpoint the leakage of combustible gas including LPG, methane, ethane, propane, butane, natural gas, coal gas, etc. Important Warm-Up Notice: Before use, the PT177 must be powered on and warmed up for 30 seconds in a clean, gas-free environment to ensure accurate detection results
- Visual and Audible Alarms: PT177 gas detector requires a 30-second auto-calibration after powering on and can detect gas and trigger an alarm within 0.5 to 3 seconds. Five red LEDs and a 75 dB audible alarm intensify as gas concentration increases
- Pocket sized with a pocket clip that allows you to carry it in your shirt pocket. The included storage bag makes the natural gas detector easy to store. It is a convenient tool for RV enthusiasts, DIYers, homeowners with gas appliances, etc
- User Friendly Features: When the battery voltage is below 2.4 volts, the power indicator light will flash to remind you to replace the battery in time. If inactive for 5 minutes without operation or detecting gas, the PT177 will automatically turn off

Leave shutoff and restoration work to the utility
Do not shut off gas preemptively, operate a meter, or relight appliances unless your utility directs you to do so. Procedures vary by utility and installation. FEMA CERT training advises households to learn and label shutoff locations, but says not to attempt a shutoff if unsure of the safe procedure; it also says only a licensed technician should turn natural gas flow back on (FEMA CERT Basic Training).
Restoration may involve utility technicians checking the system, turning meters back on, inspecting appliances, or relighting pilots. National Grid describes a process involving meter shutoff, system safety checks before gas is reintroduced, and then meter and appliance restoration; it requires an adult over 18 to be present for its relight process. Enbridge also describes technicians entering homes and tells customers not to restore service or relight appliances themselves. These are examples of those utilities’ procedures, not universal rules.
Rank #4
- WIDE DETECTION RANGE: Detect gas concentrations from approximately 50 to 10,000 ppm* (*based on Methane) for versatile gas monitoring
- ADJUSTABLE SENSITIVITY: Choose between High (50 to 1000 ppm) and Low (1000 to 10,000 ppm) sensitivity levels for accurate gas detection
- ENHANCED VISUAL AND AUDIBLE ALERTS: Stay alerted with five red LED's (visual) and 85dB audible alerts that intensify as gas concentration increases
- EASY CALIBRATION: Automatic zero-point calibration at power-up ensures accuracy; flashing lights during self-calibration, no gas presence indicated
- FLEXIBLE GOOSENECK DESIGN: Expand the sensor's reach with the 18-inch flexible gooseneck that conveniently clips onto the meter for storage
PG&E says that after its gas service shutoff valve has been closed, a qualified professional should perform a safety check before service is restored and pilots are relit. It warns customers not to turn the gas back on themselves (PG&E gas outage guidance). That guidance does not mean every planned interruption requires the same visit. Follow the directions in your own utility notice, including any access or appointment requirements.

If you smell gas or suspect a leak, leave the area and call emergency responders and your utility from a safe location. Do not use a phone, switch, flashlight, or other possible ignition source in the suspected leak area. PG&E advises avoiding ignition sources until you are at a safe distance; follow local emergency instructions.
