Beware of “fake knowledge” and “pseudo-popular science”. In addition to counterfeit and shoddy products, there is a lot of false knowledge about gas safety circulating on the Internet. These false knowledge mislead users and increase the risk of gas use. The following are some common false knowledge about gas safety and their truth:
Truth: Gas alarms must be installed in the correct position and must be calibrated and maintained regularly to ensure their accuracy. Random installation may cause the alarm to fail to detect gas leaks in time.
The truth: According to the “Town Gas Management Regulations”, no unit or individual may occupy, damage, dismantle or move gas facilities without authorization, and may not damage, cover, alter, dismantle or move gas facility safety warning signs without authorization.
The truth: Rubber hoses are prone to aging and cracking, and there are safety hazards. It is recommended to use special fuel appliance connection pipes such as metal bellows to improve safety.
The truth: After multiple ignitions have not been ignited, a certain concentration of gas has accumulated. At this time, it is strictly forbidden to use matches, lighters and other open flames to continue ignition, which is easy to ignite the gas trapped in the air, causing danger.
Correct approach: If multiple ignitions are unsuccessful in a short period of time, do not try to ignite multiple times. You should quickly open the doors and windows for ventilation and wait for the gas to dissipate before trying to ignite again.
Truth: Generally, residents add odorizer to natural gas before entering the house, so you can smell a smell similar to rotten eggs when it leaks. When the concentration of the leaked natural gas mixed with air reaches a certain ratio, if it encounters an open flame such as a lighter, even a little spark, it will quickly burn or explode.
Correct approach: If you find a gas leak, be sure to stay calm, close the gas valve, and open the window for ventilation immediately. Do not turn on or off any electrical appliances, and do not put on or take off clothes indoors. Evacuate quickly to a safe place outdoors, call the gas company’s alarm number in time, and ask professionals to handle it.
Truth: If the household gas alarm sounds, it means there may be a gas leak. If you plug in or unplug the power supply or call the mobile phone, it is easy to cause explosions, fires and other accidents due to electric sparks.
Correct approach: After the gas alarm sounds, open the doors and windows for ventilation immediately, and close the gas valve. When the indoor combustible gas concentration drops below the preset value, the alarm will stop.
People who are easily deceived: Scammers often choose to come to the door during working hours because the elderly are usually alone at home. Many elderly people are not clear about whether there are hidden dangers in the gas valves, hoses, stoves, and water heaters in their homes. Once they hear the various dangerous consequences boasted by the scammers, they are likely to fall into the scam and spend money to replace the natural gas equipment. Therefore, everyone should also often popularize anti-fraud knowledge to the elderly at home. At the same time, they should regularly check their own gas usage and not give scammers any opportunities. Their own safe gas use awareness is the best weapon to prevent fraud.
Gas safety is no small matter. In daily life, everyone should always keep a clear mind, practice “fire eyes and golden eyes”, purchase gas appliances through formal channels and formal manufacturers, and at the same time learn more correct popular science knowledge to ensure gas safety at all times.
