Approximately 40,000 households in Estonia use natural gas for heating, domestic hot water and various appliances. Natural gas is one of the safest and cleanest fossil fuels. It is also more environmentally friendly, as its combustion primarily produces water vapour and carbon dioxide, and significantly fewer greenhouse gases compared to burning oil, coal or wood.
Natural gas is highly flammable, and even small amounts produce a significant amount of heat when burned. Therefore, a natural gas leak can increase the risk of fire and explosion, as the gas spreads easily and ignites readily. If a leak occurs in a building, the gas may ignite from an electrical spark or another source of ignition.
To ensure the safe use of natural gas, you must be able to recognise the signs of a gas leak:
Smell: Although natural gas itself is odourless, the gas supplied to households contains an added odorant that makes leak detection easier. The added smell resembles that of rotten eggs. If you notice this smell inside the building, it is the first indication that you may have a gas leak.
Sound: A hissing noise coming from around gas appliances is a clear indication of a gas leak!
Houseplants: Natural gas restricts the plants’ access to oxygen. When exposed to a continuous gas leak, they begin to turn yellow or brown and eventually die. Fresh fruits and vegetables also change colour quickly in an environment with a gas leak and spoil much faster than usual.
If you suspect a gas leak in your home or apartment building, stop using gas immediately. Turn off all electrical appliances. Leave any rooms that may be affected by the leak. Inhaling a large amount of natural gas can cause suffocation and may potentially be fatal. Once you are at a safe distance from the building, call 112.
