You Smell Gas in Your Salem Home. Do This, Not That.
Short answer
Short answer: leave the house immediately, don't touch any switch or spark source on the way out, and call from a safe distance outside. This is not a situation for troubleshooting or investigation.

This page exists to be direct rather than exploratory, because a gas smell in a home is a genuine safety situation, not a diagnostic puzzle to work through calmly. The correct response is short, and it's worth reading now, before it's ever needed, rather than trying to remember it in the moment.
Leave the property immediately. Get everyone, including pets, out of the house and away from it, to a safe distance outside. This is the first and most important step, and everything else on this page happens after that step, not before or instead of it.
Disconnecting old gas water heater hose helps narrow the repair to the part of the system that actually needs attention.
On the way out, do not touch, flip, or operate any light switch, electrical outlet, appliance, garage door opener, or anything else that could create a spark. Natural gas requires a spark or flame source to ignite, and eliminating that possibility while evacuating is a critical part of the safety response, not an optional precaution.
Do not attempt to locate the source of the smell, open windows for ventilation, or do anything else inside the home once a gas smell is noticed. The instinct to investigate or ventilate is understandable, but it delays getting people out, and it's not the priority in this specific situation. Investigation and ventilation are for after everyone is safely away from the structure.
Once safely outside and away from the house, call to report the gas smell from a safe distance, using a phone away from the building rather than a landline inside it. NW Natural, Salem's gas utility provider, maintains an emergency line specifically for this, and calling them directly is the appropriate first call for a suspected gas leak, alongside 911 if there's any immediate danger.
Do not re-enter the home until it's been confirmed safe by the gas utility or emergency responders. This can feel like an overly cautious wait when nothing seems to be actively wrong, but a leak that isn't yet at a dangerous concentration inside the home can still be actively ongoing, and a professional confirmation that it's safe is worth the wait every time.
Close up water meter leak indicator gives the plumber a clearer look before the next repair step begins.
Once the immediate safety situation is resolved and the source is identified, the follow-up plumbing work, repairing or replacing the affected line, verifying the rest of the system, and re-inspecting connections, falls under fuel gas provisions of the Oregon Plumbing Specialty Code and requires a licensed plumber and, in most cases, a permit and inspection before gas service is restored to that line.
A faint, occasional gas-like smell that comes and goes, rather than a persistent, strong odor, still deserves the same seriousness of response, not a wait-and-see approach. Natural gas has an added odorant specifically so it's detectable at low concentrations before it reaches a dangerous level, which means noticing even a faint smell is the system working as intended, not something to dismiss as probably nothing.
Outdoor gas smells, near a meter, a gas fireplace vent, or where a line enters the house from outside, deserve the same seriousness as an indoor smell, though the immediate evacuation instruction shifts slightly: move away from that specific area and call from a genuinely safe distance rather than continuing to investigate or stand near the source while waiting for a callback.
Outdoor water line valve in protective sleeve can reveal the condition of the connection before parts are replaced.
Carbon monoxide detectors and gas leak detectors are two different devices worth having both of, not one instead of the other, since a gas leak detector responds to the fuel itself while a carbon monoxide detector responds to a byproduct of incomplete combustion from a malfunctioning appliance. Neither replaces the human sense of smell as the primary warning system, but both add a genuine layer of protection worth the modest cost.
Anyone who's had gas service restored after a leak repair should confirm with the technician, before they leave, that every appliance on that line, water heater, furnace, range, stove, has actually been relit and is working correctly, rather than assuming restored service automatically means every connected appliance is back to normal.
Do
Don't
Leave the house immediately
Investigate the source yourself
Get everyone and pets outside
Turn any light switch or appliance on or off
Call from a safe distance outside
Use a phone or landline inside the home
Wait for confirmation it's safe
Re-enter before that confirmation
Leave immediately, don't stop to investigate
Don't touch any switch, outlet, or appliance on the way out
Natural gas itself is odorless; utilities add a chemical called mercaptan specifically to give it a distinctive rotten-egg or sulfur-like smell precisely so leaks are detectable at low, still-safe concentrations.
Could it be something else, not actually a gas leak?
It's possible, but the correct response is the same either way: leave, don't investigate, and let a professional confirm the source rather than trying to distinguish a real leak from a false alarm yourself.
What if I only smell it faintly and only sometimes?
Treat it exactly the same as a strong, persistent smell. The odorant is designed to be noticeable well before a dangerous concentration is reached, so a faint or intermittent smell is still a genuine signal worth acting on immediately, not something to monitor and see if it gets worse.
Is it safe to open windows on my way out to help ventilate?
The priority is getting out quickly and safely; a brief pause to open a window is a personal judgment call, but it should never delay leaving, and it's not a substitute for evacuating and calling from a safe distance.
Hand showing plumbing valve in package makes it easier to confirm the problem before the line is put back into service.
Short answer: worth it if space is genuinely tight or the household regularly runs out of hot water. Not worth the extra cost if the existing gas line needs a significant upgrade and space and hot water supply aren't real problems today.
What Size Water Heater Does a Salem Home Actually Need?
Short answer: size for the busiest 30 to 60 minutes of a typical day, not average daily use, and account for household changes since the last unit was installed.
