A sulphuric, rotten egg smell is the surest sign that you have a gas leak, maybe a small leak around your stove, water heater or furnace. If gas is leaking from a pipe, appliance, or behind a wall, you may hear hissing or a whistling noise. Sometimes you can hear this hissing sound from a loose connection.
It's normal to smell gas when a gas oven or stove starts up. Every time it lights, a little bit of unburned gas will get through, which is what you smell. Your nose is very good at smelling even tiny amounts. Ovens these days generally use electric spark igniters (much safer), not a pilot light.
Thus, hissing or whistling sounds from the stove are indicators of a gas leak.
If your gas oven has been running for a couple of minutes or more and you can still smell gas, then you should turn it off immediately. This can be a very dangerous scenario, and gas is likely leaking out into your kitchen.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
If you have a gas oven, you're putting yourself at risk for Carbon Monoxide (CO) Poisoning if you try to use the oven for heat. Electric ovens are not intended for space heating so, understand that it is possible for the appliance to overheat due to prolonged usage and a resulting malfunction may cause a fire.
If you're troubleshooting the oven on a gas range, turn on a surface burner to see if it's getting gas. If a surface burner works, then you know that your oven should be getting gas as well. If the surface burner doesn't work, check the gas supply cut-off valve for your stove to make sure that it's open.
Open your windows for better ventilation. Check that stove burners, naked flames, and pilot lights are off. Finally, turn off your electricity at the fuse box. From outside the house, call your local licensed plumber or gas fitter.
Then, you need to call your gas supplier's emergency line or 911 and explain to them that you are smelling a gas odor coming from your oven and that you have evacuated your home for safety. Your gas company will come out to detect the odor and find out why it's present.

Answer: It is possible to hear a whooshing or poofing sound from any type of gas burners when the burner ignites on start-up and reignites during use. A similar poof or popping noise is also audible when the burner flame is extinguished. Burners also make a constant humming sound when in use as gas flows to the burner.
No, carbon monoxide (CO) alarms cannot detect natural gas leaks. They are designed to detect the presence of carbon monoxide, a poisonous gas formed during incomplete combustion of fuels like oil, gas, propane, and wood.
Hydrogen Sulfide
The gas has a strong scent of rotten eggs, which makes it distinct from other, similar gases. If you detect this rotten egg scent and you are using hydrogen sulfide at your facility, this could be evidence of a leak.
Unfortunately, natural gas won't always emit a smell when it escapes. That means you can have a leak in your home and not even know it! Gas leaks can result in a host of health issues and even fatality in certain situations. With so much at risk, the last thing you want to do is let a gas leak go on for too long.
Go to the Home app on your iPhone or iPad. , then tap Home Settings. Tap Safety & Security. Tap Sound Recognition, then turn on Smoke & CO Alarm.
Malfunctioning oil, wood, gas, or coal furnaces. Malfunctioning gas clothes dryer. Wood burning fireplace or gas log burner. Gas or fuel-burning appliances in cabins or campers, barbecue grills, pool or spa heaters, or ceiling-mounted heating units.
WHY DOES MY OVEN SMELL LIKE GAS WHEN PREHEATING? Preheating a gas range triggers a combustion of gas at the oven's burner, which can cause a gas smell as it heats up. If your gas oven smells like gas, then the smell should dissipate after the first few minutes of preheating.
Signs of a carbon monoxide leak in your house or home
Sooty or brownish-yellow stains around the leaking appliance. Stale, stuffy, or smelly air, like the smell of something burning or overheating. Soot, smoke, fumes, or back-draft in the house from a chimney, fireplace, or other fuel burning equipment.
