1. The safe use period of gas facilities: The State Bureau of Quality and Technical Supervision promulgated the "Safety Management Regulations for Domestic Gas Burning Appliances", which clearly stipulates that the gas-fired water heaters have a default period of 6 years from the date of sale, and the liquefied petroleum gas and natural gas water heaters have a default period of six years. In the past 8 years, the life limit of gas cookers has been 8 years. If the use is overdue, there will be problems such as unstable combustion and unqualified emissions. The hose used to connect the gas appliance requires the use of a pressure-resistant and oil-resistant gas-only plastic hose (green polyethylene reinforced pipe) or a metal hose. After installation, check that there is no dead bend. The service life of gas-specific plastic hoses is 2-3 years. It is prone to aging or even cracking when it is long, and it is prone to safety hazards such as gas leakage. Therefore, regular inspections and replacements are required. The service life of metal hoses is about fifty years. 2. How to use the gas stove safely: 2 When using, people should not stay away from the scene, so as to avoid boiling out of the soup or blowing out the flame by the wind, causing gas leakage; 3 After use, you should pay attention to the cooker switch and confirm that the flame is extinguished. If there is no one in the family for a long time or go out for a long time, be sure to close the front valve of the gas meter; 4 The hose connecting the cooker should be naturally drooped under the cooker and kept at a distance of 10 cm from the cooktop to avoid being burnt by fire and causing an accident; 5 Pay attention to ventilation when using, keep the indoor air fresh and circulated. Always keep the stove clean and minimize the movement. Do not place flammable materials on and around the cooker to eliminate fire hazards. 3. How to safely use gas water heaters: 1 When the water heater has a yellowing, smoking, or irritating smell, stop using it and carry out maintenance; 2 When the water heater appears “empty†(no water or water is turned off and the main burner is still burning), it should be stopped immediately and repaired; 3 When the water heater has abnormal conditions (fire, deflagration, water leakage, air leakage, noise, vibration, etc.), immediately close the gas valve and water valve; 4 After using the water heater for a period of time, it is necessary to ask the professional to check and carry out targeted maintenance; 5 The water heater should be installed in the kitchen. It is strictly forbidden to install it in the bathroom. Users are not allowed to dismantle, change, move or install it. In-line gas water heaters were banned from production and sales in 1999; 6 The room where the water heater is installed should have the condition of outdoor ventilation. The flue type and the strong exhaust type water heater should not be used if the flue is not installed. 4. How to properly install gas facilities: After the gas is burned, a trace amount of carbon monoxide is generated. Carbon monoxide is a toxic gas. In normal combustion, the amount of carbon monoxide generated in the flue gas is small and does not cause harm to the human body. However, if the fresh air is not replenished in time to make the gas burn incompletely, a large amount of carbon monoxide will be generated, causing poisoning, light dizziness and vomiting, and severe death. Indoor decoration, the gas pipes and gas meters in the kitchen cannot be sealed tightly; because gas leakage occurs, it is not easy to find, but also because the space is small, the mixture can quickly reach the explosive concentration, and it will explode when there is Mars. , fires and other accidents. 5. How to check the gas leakage at the gas facility connection: In addition to special instrument inspection, soapy water (washing water, washing powder water can also be checked) is a safe and reliable method. Mainly check the connection of pipelines, pipelines and gas meters, gas equipment. When checking for leaks, use a soft brush or a brush to apply soapy water. It is found that the place where the soapy water bubbles is the leaking part. In addition, you can use the smelly way to find the leaking part, but you must not use an open flame to check for air leaks. Â
