How to avoid gas leakage
To avoid gas leakage, you can start from equipment selection and installation, daily use habits, regular inspection and maintenance, personnel training and emergency preparedness. The following are specific methods:
Equipment selection and installation
Select qualified products: Be sure to use gas appliances that meet national standards. It is strictly forbidden to use infrared stoves, because they will produce harmful gases due to incomplete combustion, which can easily cause indoor poisoning. At the same time, you must choose qualified gas stoves, water heaters and other equipment produced by regular manufacturers.
Professional installation: Gas appliances should be installed in accordance with regulations by professional teams. Do not connect or modify gas equipment privately. If you need to change the direction of the gas pipeline or connect or modify gas facilities, you should contact the local gas company in time and have professionals operate.
Avoid closed installation: Do not install gas meters and gas pipelines in closed cabinets. Ensure that there are good ventilation conditions around them to prevent gas accumulation.
Daily use habits
Correctly switch valves: After using gas, be sure to turn off the stove switch and gas pipeline valve at the same time. Natural gas users must close the valve in front of the stove before going to bed. Don't just think that turning off the gas stove switch is enough. When using, open and close the valve gently to avoid excessive force.
Use with someone watching: When using gas, someone must watch to prevent the flame from being extinguished by boiling water or blown out by the wind. If you are cooking and need to go out temporarily, you need to turn off the gas stove in time.
Keep ventilation: Long-term use of gas must be ventilated. If the kitchen is not well ventilated, using a gas stove will cause insufficient oxygen in the kitchen, which can easily cause carbon monoxide poisoning. An exhaust fan can be installed in the kitchen. A double-eye gas stove is installed in a kitchen with a volume of less than 6 cubic meters, and the ventilation should be no less than 5 times per hour1.
Ignite first and then turn on the gas: When using natural gas, ignite first and then turn on the gas. If it does not ignite once, turn off the natural gas stove switch quickly. Do not deflate first and then ignite. When using an automatic ignition stove, push the switch knob inward, rotate it in the direction indicated by the arrow to ignite and adjust the flame size.
Do not rely on the alarm: Do not rely on the gas alarm and be careless. The gas alarm may sometimes be misleading, and may not alarm when the gas leaks for various reasons. Residents of household gas alarms are unlikely to check, replace airtight components and perform maintenance in time.
Educate children: Educate children not to play with valves on gas pipelines or gas facility switches to avoid damaging the stove or forgetting to close the valve.
Regular inspection and maintenance
Check the connection parts: Always check whether the hose connection is fixed with clips and whether the hose is aging or cracking. The most prone parts to gas leakage are the gas meter housing, various connection points on the gas pipeline, gas nozzle cock, hose, etc. The hose should be replaced every two years. For safety reasons, it is recommended to replace it once a year.
Check the equipment status: Regularly check whether gas equipment, including pipelines, valves, stoves, etc., are working properly, and whether there is aging, damage or leakage. If the flame is found to change from blue to yellow or there are other abnormal conditions, the maintenance department should be notified in time for processing.
Avoid heavy objects squeezing: Do not hang heavy objects on the gas pipeline, do not use it as a grounding wire, and do not place flammable items on it to prevent the pipeline from deforming or being damaged and causing leakage.
Emergency preparation and awareness
Know the alarm phone number: Once you find a strange smell, open the doors and windows immediately. At this time, all kinds of fire are strictly prohibited from entering the room, and the lights cannot be turned on or off to prevent gas explosions.
Read the safety content: Carefully read the safety publicity content on the back of the gas purchase invoice, and take preventive measures to prevent accidents such as gas leaks, fires and gas explosions.
Equip with fire extinguishing equipment: Families with conditions can be equipped with small fire extinguishers or a small amount of dry powder fire extinguishing agent to prevent gas accidents.
