You can keep LPG gas cylinder in the kitchen, but it’s not at all recommended and avoid as much as possible.
- Never keep the LPG gas cylinder in a confined cavity below the kitchen platform enclosed by modular kitchen shutters. As LPG is heavier, if gas leaked it will not get dispersed outside resulting in a higher concentration of gas inside the cavity causing cylinder body gets heated when a fire occurs and cylinder explodes.
- Always keep the LPG gas stove on a platform above the LPG gas cylinder level.
So the MUST NOT reasons are (1) In case of a fire in kitchen, if cylinder is in kitchen, it will NOT be easy to close regulator value to stop gas supply to fire and (2) If you are unable to put-off the fire quickly, cylinder body gets heated and explode as mentioned above.
What are the preferred locations to keep LPG gas cylinder at home?
- Independent house – Preferably outside the home (refer below conditions).
- Keep the cylinder outside the home with a small chamber (to avoid theft) if possible. Even if you are keeping outside home in a room, ensure that the room is not with combustible material. This is to ensure that the cylinder does not get heated if an accidental fire happens.
- If you are keeping LPG gas cylinder inside the home, ensure that you are keeping in any ventilated space other than the kitchen. Ideal space will be the one accessible to close the cylinder valve in case of fire inside the kitchen.
- Flat / Apartment – In balcony or area with maximum exposure to open air except kitchen.
- Ideal space will be the one accessible to close the cylinder valve in case of fire inside the kitchen.
- Ensure that we do not store the room with combustible material to avoid cylinder body getting heated in case of a fire caused by combustible material.
What are the safety precautions you must have at home associated with to use of an LPG gas cylinder?
- Foremost, install an LPG (gas) leak sensor in the kitchen. Standalone sensors are available at low cost. Preferred to choose the one with battery backup.
- Ensure that sensor is installed at a lower level (as leaked LPG settle down) near to LPG gas cylinder (if located outside of kitchen) and/or stove.
- Have fire detection sensor in the kitchen and place where LPG gas cylinder is placed. Standalone battery-operated sensors available at low cost.
- Every time when you change the LPG gas cylinder, observe for gas leaks immediately and after 15 to 30 minutes. Hardened rubber washer on the cylinder next where regulator connects may cause leakage. Call gas distributor if leak observes. I observed the leak a few times and swapped the rubber washer (using a twicer) from an empty cylinder to solve the leak.
- You may substitute the standard gas regulator with an approved (preferably BIS approved) Automatic Gas Safety regulator with Gas Leakage Detector and Auto Cut Off mechanism. This automatic regulator helps to cut off the gas from stove to stove, in case if flame off due to wind or spill over of water from vessel or pipe leak situations. Consult with your LPG supplier before you substitute the regulator.
- Even there are gas stoves available in the market with automatic gas cut-off valve so that when flame off because of any reasons mentioned above will not cause gas filling up in the kitchen.
- Empty and full LPG cylinders must be kept in a cool and well-ventilated area with safety cap fixed.
- Always use BIS-approved appliances, including regulators.
- MUST not keep LPG gas cylinder at entrance of the house as in case of fire, it will obstruct the safe exit from the house.
Specifications & Best Practices for LPG gas pipe connection between cylinder and stove
You can either use copper or stainless-steel pipe to connect the LPG gas cylinder. But must ensure you use right pipe specification and follow best practises listed below.
- Copper pipe
- Insist sleeved copper pipe with 3/8 x 14 SWG (gauge) specification.
- Must use sleeved copper pipe to avoid risk of melting in case of any earth leakage in building.
- Must install shut-off valves at cylinder and stove ends.
- Insist single pipe without joints.
- Better not to conceal the pipe, especially when you have a joint (if unavoidable) in the pipe. Or have the joint area visible through a junction box if case if you have concealed.
- If concealed the pipe, mark on wall so that no one will accidentally drill or nail on that area.
- Ensure that the contractor does the pressure test after the installation.
