Piped gas has a good safety record, and most families who use it never face a leak. But if you ever walk into the kitchen and catch that strange, sharp smell, what you do in the next two minutes matters more than anything else in this article.
This guide covers exactly what to do if you smell gas, the emergency numbers of the main PNG companies, and the everyday habits that keep a PNG kitchen safe. It’s worth reading once now, while nothing is wrong.
How You’ll Know There’s a Leak
Natural gas on its own has no colour and no smell. That’s why gas companies add an odorant to it, so that a leak can be noticed. IGL explains this in its own safety tips. So if you smell something like rotten eggs or cabbage near the stove, pipe or meter, treat it as a leak.
Natural gas is also lighter than air. If it leaks, it rises and moves upwards, unlike LPG, which is heavier and settles near the floor. That works in your favour, but only if the kitchen is ventilated and the gas has somewhere to go.
If You Smell Gas: Do This Now

- Don’t light anything. No matchstick, no lighter, no stove, no candle, no cigarette.
- Don’t touch electrical switches. Don’t switch lights, fans or appliances on or off. Even a small spark from a switch can be dangerous.
- Turn off the gas. Close the burner knobs and the appliance valve on the pipe. If you can reach it easily, close the main valve near the meter too.
- Open doors and windows to let the gas escape.
- Get people out if the smell is strong, especially children and elderly family members.
- Call your gas company’s emergency number. If you can, make the call from outside the house.
- Wait for the company’s team. Don’t let a local plumber or mechanic try to fix it. IGL specifically asks customers not to call local plumbers for any PNG repair.
PNGRB, the regulator, gives the same core advice: close the valve in the kitchen and inform the company on its emergency number immediately.
PNG Emergency Numbers in Major Cities

Your city not listed, or not sure which company supplies your area? Your gas company’s emergency number is usually printed on your PNG bill, and PNGRB’s website has the full list for every area.
Save your company’s emergency number in your phone right now, and in your parents’ phones too. In a real emergency, nobody wants to be searching for it.
Why PNG Needs a Slightly Different Kind of Care
Because natural gas rises, the dangerous spots are different from LPG. Leaked gas can collect in enclosed spaces where it can’t escape, like a closed cupboard built over the pipe. IGL asks customers to check whether their PNG pipe is hidden under a kitchen cupboard and to get it moved into the open, because leaked gas could otherwise build up there.
The same logic applies to geysers. Indian Oil-Adani Gas says a gas geyser should never be installed in a bathroom or any closed, concealed area.
Everyday Habits That Keep You Safe
These come straight from the gas companies’ own safety advice:
- Close the appliance valve after cooking, not just the burner knob.
- Close the gas tap before going to bed at night.
- Turn off the meter control valve if your home will be locked for a day or more.
- Open the doors and windows every morning before you light the stove.
- Check the rubber tube between the pipe and the stove for cracks or cuts. Use only a tube approved by your gas company. IGL recommends a SURAKSHA rubber tube.
- Don’t cover the rubber tube, and keep it clean.
- Keep the meter easy to reach and well ventilated. PNGRB says the meter should be in an accessible, airy place.
Things You Should Never Do
- Never fiddle with the pipeline, meter or fittings, and never shift them yourself.
- Never start renovation or construction near the gas pipe without informing the gas company first.
- Never ignore digging near the gas pipeline outside your building. Report it to the company.
- Never burst crackers or burn garbage near PNG pipelines. Worth remembering in the festival season.
If the Gas Suddenly Stops
Sometimes the supply stops for a while, perhaps because of maintenance or a problem in the line. If the flame goes out on its own:
- Close the burner knob immediately, so gas doesn’t flow out unlit when the supply returns.
- Open doors and windows.
- Light the stove again only when there’s no smell of gas.
- If the supply doesn’t return, call your gas company’s customer care.
Teach Everyone at Home
A safety plan only works if everyone knows it. The person who notices the smell may not be you. It could be your mother, your teenage son or the cook who comes in the morning. Take five minutes this week to show everyone where the appliance valve and the meter valve are, and how to close them. Write the emergency number on a piece of paper and stick it on the fridge. It feels like a small thing, until the day it isn’t.
Quick Answers
What should I do first if I smell PNG gas?
Don’t light anything or touch electrical switches. Turn off the gas valve, open doors and windows, and call your gas company’s emergency number.
What is IGL’s emergency number?
155216, for gas leaks in Delhi and NCR.
Can I call 1906 for a PNG leak?
1906 is the LPG emergency helpline. For PNG, call your own gas company’s emergency number, which is on your bill.
Is PNG safer than LPG?
It has an advantage, because natural gas is lighter than air and rises if it leaks. But a leak in a closed space is still dangerous, so the safety habits matter.
Can a local plumber repair my PNG pipe?
No. All repairs and changes should be done only by your gas company’s team.
Save the Number Today
PNG is one of the safest ways to cook, and following a few simple habits keeps it that way: close the valve after cooking, keep the kitchen airy, never hide the pipe, and never let anyone but the gas company touch the line.
