Soak in bleaching powder solution: Bleaching powder solution is made up of a small spoon of bleaching powder and two cups of cold water. Put the washed cooking utensils in the soak, take them out after two minutes, rinse them with clean water, and then use them. There are many ways to disinfect tableware. The simple way is to disinfect tableware with detergent. Place the used utensils in a basin, inhibit the temperature, drop a little detergent, wash them with clean water, and put them in the cabinet. Potassium permanganate can also be used for disinfection. Take about 10 pieces of zinc permanganate, add more than half a basin of cold water, soak tableware in potassium permanganate solution for 10 minutes, then sterilize it, and then wash it with clean water and use it. The most ideal disinfection method is to put the washing utensils into the pot, soak them completely in water and heat them. When the water is boiled, the disinfection can be achieved by keeping them for two minutes. Disinfection of tableware into the cabinet, or covered with gauze, the remaining water natural drying, do not wipe with a rag, in order to prevent re-pollution. If the tableware is used by the patient, it must be cleaned and disinfected separately.
95% of indoor gas accidents are due to improper use of user gas, which leads to gas leakage. The causes of gas leakage are: overtime use of hoses, aging cracks and shedding; failure of ignition of stoves, direct leakage of unburned gas; liquid overflow, extinguishing the burning flame; pipeline corrosion or damage of gas meters, valves, interfaces, and artificial damage to indoor pipelines such as rope pulling, suspension items and other external forces. In addition, in winter, users will close doors and windows, air flow is not smooth, gas leakage occurs, not easy to disseminate, more likely to occur gas accidents. In order to ensure the safety of gas use, we must pay attention to the service life of domestic gas appliances and replace them when they expire. According to the Rules for Safety Management of Household Gas Burners, from the date of sale, the period of abandonment of stoves is 8 years. Although some cookers that have been used for more than 8 years are superficially intact, they have exceeded the guaranteed service life due to the aging of their components. When using old cookers for more than 8 years, carbon monoxide is easy to exceed the emission standard when burning, and the emission of carbon monoxide concentration may exceed the national regulations by more than 7 times.
Thermal efficiency is an important index to measure whether a stove is energy-saving. The gas industry is using this index to measure whether the stove is energy-saving, and the inspection report issued by a professional third party must be taken as the standard. The energy-saving stove with general thermal efficiency of more than 70% is a good choice. Energy-saving rate is a concern of many customers, many manufacturers will make a big fuss on this data, in fact, the test data should be the basis, the general energy-saving rate of large stoves in more than 40% is very good. Carbon monoxide produced by combustion is harmful to human body and environment. The national standard is no more than 0.1%. The smaller the value, the better. Noise is also a kind of pollution. Good energy-saving stoves have low noise. This is a very simple test method, good energy-saving stove smoke outlet temperature is very low, and the general stove smoke outlet is not close at all.
