With the continuous reduction of temperature, heating and bath gas increased, and entered the peak period of gas household. According to statistics, at least 90% of gas accidents occur in winter every year. The aging of gas hoses and carbon monoxide poisoning caused by improper use of gas water heaters are the biggest hidden dangers.
According to the person in charge, at present, most of the gas hoses used in Chengdu residents’homes are ordinary plastic hoses, because of their material characteristics, easy to fold, wear and tear, poor thermal radiation resistance, the use of 2 years need to be replaced. If not replaced in time, aging and cracking may occur. A gas leak and explosion accident caused by a rat’s bite through the hose often happens. Since the end of last year, the Chengdu Gas Department began to replace the metal-armoured composite gas hoses for new users and some old users, and nearly 50,000 households have completed the replacement. But many people still use ordinary rubber hoses. Therefore, the responsible person appealed to the public to install more secure armoured hoses.
In addition, carbon monoxide poisoning caused by improper use of water heater has also become a major hidden danger in the use of gas. Remind the public: Do not use gas water heater for a long time, no more than 30 minutes each time, keep indoor and outdoor air circulation at any time, to avoid long-term work of the water heater caused by indoor oxygen content dropped sharply, resulting in hypoxic asphyxia. Check the gas facilities at home regularly. The safe life of gas appliances is 8 years, and they need to be replaced in due course.
