The hazards of family fires are great, and the specific analysis is as follows:
During the process of a domestic fire from the initial stage to the violent development stage, the indoor temperature rises rapidly, the oxygen content becomes less and less, and the combustibles are gradually incompletely burned, and the combustion produces a large amount of chemical poisonous gases such as thick smoke and suffocating carbon dioxide. The smoke mixture irritates the human eyes, nose, trachea, lungs and other organs, which brings difficulties to the rescue work. The main components of chemical poisonous gas are CO, HCN, NO2, SO2, H2S. When the concentrations of these poisonous gases reach a certain value, they may cause death in a short time. The combustion of various utensils in the home is the main source of these poisonous gases, such as the combustion of wooden furniture to produce CO, HCN, NH3; the combustion of textiles to produce CO, HCN, NO2, NH3, CH3CHO; the combustion of plastic, rubber, and leather to produce CO, SO2, H2S , HCN, NO2. There are many sources and types of poisonous gas produced by domestic fires. If people are not evacuated in time, the fire will easily suffocate and poison people, especially the elderly, sick, children and disabled people.
Careless use of electricity
There are many types of electrical appliances commonly used in modern households, among which quality defects account for a considerable proportion, and wires and flame-retardant tubes also have problems of inferior quality. During the use of these electrical appliances, due to their own quality problems and imperfect electrical power-on, power-off, and grounding protection measures, leakage and short-circuit will occur, which will cause the internal voltage and current of the electrical equipment to suddenly increase, resulting in combustion or explosion. In addition, common illegal electricity usage in households such as aging, exposed lines, loose connectors, and unauthorized connections can easily lead to fires caused by short circuits, excessive contact resistance, or overloading of lines and electrical appliances.
Household fires can be caused by careless use of electricity in various forms. The use of electrical appliances that generate high heat, such as electric irons, electric frying pans, etc., is likely to be dismantled due to the failure of heat regulation components, combustibles being too close to electrical appliances, and electrical insulation protection devices. Combustibles can be ignited or damaged; for electrical appliances that do not generate high heat, such as TVs, stereos, washing machines, etc., the capacitors in the internal electronic circuits are prone to failure and the transformer is overloaded, causing heat to catch fire; commonly used heat-generating lighting fixtures are used Installing near combustibles or places that are not conducive to heat dissipation can also cause fires.
Careless use of fire
Careless use of fire in life can easily cause fires, and many aspects of family life are inseparable from the use of fire. Fires caused by inadvertent use of fire mainly have the following three aspects:
1. Careless use of fire when cooking. Kitchens are generally small in size, densely packed with items, and frequently use fire, which is prone to fire accidents. For example, when frying food, too much oil overflows or the pan is unstable so that the oil overflows and burns when exposed to an open flame; when cooking, people leave and cause the food to be scorched and ignited; It is also possible to ignite the mouth of the liquefied gas tank when the partition is removed.
2. Careless smoking. The surface temperature of the cigarette butt is 300-450°C, and the center temperature is 700-800°C. When the soot of the cigarette butt is bounced off, some irregular particles have sparks. Hours of smoldering can cause a fire. When lying on the bed or sofa and smoking, if people fall asleep before the cigarette is extinguished, the cigarette butts will easily fall on the bed or sofa, which will eventually lead to fire and casualties.
3. Inadvertent heating. The brazier is fixed on the wooden frame for a long time, which causes the surrounding and bottom of the wooden frame to be scorched and charred and catch fire, igniting the adjacent combustibles and causing a fire; The roasting or drying cage was overturned, and the bedding was ignited to cause a fire, and often caused casualties.
The decoration adopts non-combustible and flame-retardant materials
Use non-combustible and flammable materials as much as possible for interior decoration
First of all, the main design of the building must ensure that it meets the requirements of fire codes. Residents should try their best not to use flammable and combustible materials when carrying out interior decoration, so as to avoid increasing the fire load of the living room and reducing the fire resistance level of the living room. It is necessary to properly handle the contradiction between decoration effect and safety, actively use non-combustible and difficult-to-combustible materials, and avoid the use of building materials that produce a large amount of poisonous gas after burning, so as to be safe, applicable, advanced in technology, and economical and reasonable.
