Power safety check

Generators, fuel, heaters, batteries, and high-load devices can create fire, carbon monoxide, shock, and ventilation risks. Follow manufacturer manuals, local codes, and official safety guidance before use.

Backup Power

Smell Gas, Leave: Earthquake Gas Shutoff, Electrical Safety, and Backup Power

Smell gas after a quake? Leave, then shut it off from outside. Downed-wire rules, and backup power for the fridge, phones, and medical devices.

Quick Answer

After the shaking stops, the biggest hazard is often the gas line, not the building. The rule is simple and it comes first: if you smell gas, hear hissing, or see a broken line, get everyone out, do not flip any switch, and do not light anything. Shut the main off at the outdoor meter with a wrench, then leave and call from a safe distance. Do not shut the gas off as a reflex if there is no sign of a leak, because only the utility can safely turn it back on and that can take days. For electrical, treat every downed wire as live, and if you see arcing or smell burning, kill the main breaker if you can reach it safely. Then comes the boring, useful part: backup power for the fridge, phones, and any medical device, sized in watt-hours so it actually lasts.

Confidence: high

Key Points:

Smell gas, hear hissing, or see a broken line: leave first, then shut the main at the meter from outside. No switches, no flames, no ignition sources.
Do not shut off gas without a reason. Only the utility restores it safely, and that can mean days without hot water or cooking.
Keep a wrench zip-tied at the gas meter. A stiff quarter-turn valve is useless if the tool is in a drawer inside a damaged house.
Every downed power line is live until proven otherwise. Stay back at least 30 feet and keep others away.
Size backup power in watt-hours: a fridge needs about 1,200 Wh a day, phones are a rounding error, and a CPAP or oxygen concentrator has its own number you must know in advance.
Confidence: high

What to Power After a Quake, and What It Costs

Load	Typical draw	Per day	Realistically covered by
Refrigerator	100-200W, cycling	~1,200 Wh	2 kWh+ station with solar, or a fuel generator
Phones + weather radio	10-30W	Under 150 Wh	Any decent power bank
CPAP (no humidifier)	30-60W	~300-500 Wh/night	A 500 Wh+ station; run humidifier off to save power
Oxygen concentrator	300-600W	7-14 kWh	Large battery bank with solar, or a generator; confirm your unit's rating

The Gas, Electrical, and Power Mistakes That Turn Dangerous

A quake rarely kills with the shaking. It is the gas, the wires, and the generator afterward. These four are the ones that put people in the hospital.

Flipping a light switch with gas in the air

A switch, a garage door opener, a phone screen, or a lighter can spark a gas explosion. People walk into a dark, damaged house and reach for a switch out of pure habit.

Better approach: If you smell gas, use nothing electrical and light nothing. Get out, shut the meter off from outside with your wrench, and call the utility from a neighbor's or the street.

Shutting off the gas when there is no leak

Turning the main off is a one-way move: only the gas company can safely relight and recertify the system, and after a major quake that queue can be days long. A needless shutoff leaves you without cooking or hot water for no reason.

Better approach: Shut off only if you smell gas, hear it, see a broken line, or a fire official tells you to. No signs of a leak means leave it on and check for damage instead.

Treating downed or damaged wires as dead

A power line on the ground can still be energized and can charge nearby fences, puddles, and wet ground. Assuming the outage means the wire is safe is how people get electrocuted after the quake is over.

Better approach: Stay back at least 30 feet, keep kids and pets away, and call it in. If you see arcing or burning smell inside, cut the main breaker only if the panel is dry and you can reach it safely.

Buying a generator and ignoring the medical load

Families size backup power for the fridge and forget the device that actually cannot fail: a CPAP, an oxygen concentrator, or refrigerated medication. Then the outage runs long and the critical load is the one that dies first.

Better approach: List medical loads first, in watt-hours, and give them a dedicated battery with solar recharge. Confirm the device's real draw now and keep the manual with the power station.

Gas, Power, and Safety Questions, Answered Straight

Done-for-you: solar backup sized for a long outage

If you would rather not improvise power for the fridge or a medical device, Grid Doctor systems pair the battery and panels so the sizing is already handled. Smaller units cover phones, a radio, and a CPAP; larger systems carry fridge-plus-medical duty and recharge from the sun while the grid is down.
