What does the gas burner emergency switch look like?
The emergency gas shut off switch is located on the front of the stove or cooktop. It is usually red in color and labeled with words like “Gas Shut Off Valve” or “Emergency Gas Valve.” The switch itself is flat and rectangular in shape. Most switches have an “On” and “Off” position clearly marked.
Where can I find the emergency gas valve on my stove?
The exact location can vary depending on the brand and model, but in most cases the gas shut off valve is found on the front lower right corner of the cooktop. It may be behind a small panel that pops open or screwed into place. Refer to your owner’s manual if you have trouble locating it.
Why is the emergency gas switch important?
The emergency gas valve serves a crucial safety purpose – it allows you to immediately stop the flow of gas to the burners if you smell a gas leak or in any type of emergency situation. This can prevent fires, explosions and carbon monoxide poisoning. Having a gas shut off switch within quick reach can literally be a lifesaver.
When should I use the emergency gas valve?
There are a few scenarios when you need to use the emergency gas shut off switch right away:
- You smell a strong gas odor in or around the stove
- You hear a hissing sound coming from the gas line
- A burner flame goes out and continues to emit gas
- A fire starts on or around the stove
- An earthquake or other disaster strikes your area
In these situations, immediately flip the emergency switch to the “Off” position to stop the flow of gas. This can prevent a dangerous gas leak, explosion or fire from occurring or getting worse.
How does the emergency gas valve work?
The emergency gas shut off valve is connected to the main gas supply line running to the appliance. When switched to the “Off” position, it stops the flow of natural gas or propane to the stove’s burners and oven. This instantly cuts off the gas supply and extinguishes any open flames.
Most valves use a 90-degree turn mechanism. Turning the switch clockwise to the “Off” position ensures the valve shaft rotates and interrupts the flow of gas. Once in the closed position, no more gas can flow past the valve even if burners are turned on.
Can I turn the emergency gas valve back on myself?
Only turn the emergency gas valve back to the “On” position if you are certain it is safe to do so. Make sure:
- The gas leak has been stopped.
- Any fires have been fully extinguished.
- No gas odor or hissing sound can be detected.
- Appliance and igniters are undamaged.
If you are unsure, call your gas company or fire department first. They can determine if it is safe to resume the flow of gas to the appliance.
In many cases, a certified technician will need to come inspect the appliance and gas lines and turn the valve back on. This ensures everything is in good working order before gas flows again.
What should I do after turning off the emergency gas valve?
After switching the emergency shut off valve to the “Off” position, follow these important steps:
- Evacuate everyone from the building immediately.
- Call 911 once outside to report the emergency.
- Inform the gas company from a safe location.
- Do not re-enter the building until officials say it is safe.
- Do not turn the gas back on until the leak is fixed.
- Have appliances inspected by a professional before using again.
This will ensure the proper authorities can respond, the leak is addressed, and the appliances are safe to operate again after such an event.
What are signs of a gas leak to watch out for?
Watch for these common indications that a hazardous gas leak may be occurring:
- Strong natural gas smell – like rotten eggs
- Hissing, whistling or roaring sound
- Dead or dying plant life in one area
- Dirt blowing from a hole or crack in the ground
- Bubbles in standing water
- Flames if leak has ignited
If you detect any signs of a gas leak, use the emergency shut off valve immediately then call the authorities.
Can I test to see if the emergency gas valve works?
You should not routinely test the emergency gas valve yourself. However, it is a good idea to visually check it at least twice a year.
Look for the following:
- Switch moves freely between “On” and “Off”
- Valve handle is not damaged/missing
- Valve seat is intact with no cracks or corrosion
- No obstructions blocking the valve
If damage is present or the valve seems stuck, call a technician to replace it. Never try to repair the emergency gas valve yourself.
Why is my emergency gas valve leaking after shutting it off?
If you can hear or smell gas leaking from the emergency shut off valve, there are a few possible causes:
- Valve seat is worn, damaged or corroded
- Debris is stuck in the valve obstructing full closure
- Internal components of the valve are broken
- Pipe threads are damaged causing leak at connection
This is a dangerous situation requiring immediate repairs. Call a professional to replace the leaking emergency gas valve completely.
Should I secure my gas valve in the off position before extended vacations?
Yes, it is recommended to turn the emergency gas valve to “Off” if you will be away from home for a long period of time. This adds an extra level of safety and security while you are not there to detect problems yourself.
Before leaving, simply rotate the gas valve clockwise to the “Off” position. Take a minute to make sure all burners and pilots are out. When you return, make sure there are no leaks before turning the gas back on.
My emergency gas valve is stuck and won’t turn – what should I do?
Do not try to force or repair a stuck emergency gas valve yourself. A stuck valve that cannot move easily between “On” and “Off” poses a safety risk and requires a qualified technician to service it.
Call for professional help immediately if the emergency shut off valve is stuck. Until repairs can be made, avoid using the stove and do not attempt to turn on any burners, pilot lights or oven ignition.
Is there an alternate way to shut off my gas if the valve fails?
If the emergency gas valve fails or is inaccessible, the main shut off valve located at the gas meter or propane tank can be used to shut off gas to the entire building. Use the main valve if:
- The emergency gas valve is broken
- The emergency gas valve cannot be reached
- There is a leak at the emergency gas valve itself
Make sure you know where your main gas shut off is located before an emergency occurs.
Should I replace my old emergency gas valve?
Emergency gas valves should be replaced if:
- Older than 10-15 years
- Corroded or damaged
- No longer functioning properly
- Leaking gas past the valve seat
- Difficult to turn or stuck
Do not put off replacement of an outdated or defective emergency gas valve. A properly working valve is crucial to safely cutoff the gas in the event of leaks, fires or other hazards.
