Car fire extinguisher column reminds one large fire load, smoke and toxic gases produced by combustion
With the increasing of urban and rural residents in the material and cultural living standards, modern home appliances gradual diversification of supplies, but most of these items by C, H, O, N and other elements, is combustible or toxic substances, purchase or blind fitting these items increased fire load of the family, for the expansion of the spread of fire to provide the conditions.
Home fires from the early stages of the development process in the violent, the indoor temperature rises rapidly, less oxygen content, combustible gradually to incomplete combustion of the main combustion produces a lot of smoke and suffocating gas carbon dioxide and other chemical properties. Flue gas mixture stimulate the eyes, nose, trachea and lungs and other organs, to bring workers fighting difficult. The main ingredient is a chemical poison gas CO, HCN, NO2, SO2, H2S, when the gas concentration reaches a certain value, are likely to result in death within a short time. Household appliances of various combustion is the main source of such gas, such as wood furniture burning CO, HCN, NH3; textiles combustion CO, HCN, NO2, NH3, CH3CHO; plastics, rubber, leather combustion CO, SO2, H2S , HCN, NO2. Wide source of household gas fires, and variety, if not timely evacuation, fire, poisoning, choking easily, especially the elderly, the sick, children and the disabled.
Third, life can lead to careless use of fire fire, many aspects of family life are inseparable from the use of fire. Fire with fire accidentally caused mainly in the following three aspects:
1, careless use of fire while cooking. General kitchen area is small, dense objects, the number of frequent use of fire, fire-prone. Such as fried foods, the oil spill or excessive instability in the oil pan overflow in case of fire burning; when cooking, people leave food is burned by the ignition lead; when the gas tank away from the stove and the stove too close and no There may ignite LPG Tanks mouth when the spacer.
2, careless smoking. Cigarette surface temperature of 300-450 ¡æ, the center temperature of 700-800 ¡æ, when bounced off the cigarette ash, some irregular particles with Mars, if the fall is relatively dry, combustible materials on the loose, after one to three hours can cause smoldering fire. Lying in bed, on the couch smoking when people fall asleep before the smoke does not destroy, it is easy to make a cigarette falls on the bed or on the couch, eventually leading to a fire and casualties.
3, heating accidentally. Brazier long-term fixed on the gallows, causing peripheral and scorched wooden bottom, charring and fire, igniting a fire caused by combustible materials near; in addition, some older people in the winter like to bake into the cage bedding heating, due to prolonged drying grilled or baked cage tipped, bedding was ignited fires, and often resulting in casualties.
Fourth, indoor decoration maximize the use of non-combustible, flame retardant materials
The first is the main architectural design to ensure compliance with the Fire Code requirements. When performing household interior decoration, as far as possible without combustible and flammable materials, avoid fire load increases bedroom, bedroom lower fire rating. To properly handle the contradiction between decoration effect and safety, and actively using inflammable and flame retardant materials, to avoid the use of a large number of gas after combustion of building materials, so that the security of application, advanced technology, reasonable economy.
Five, to ensure the quality of electrical lines to prevent electrical fires
Electricity accidentally caused fires occur throughout the day and always family life, and make good use of it was a blessing, no use of the havoc. Prevent electrical fires, first according to the specific requirements of moisture, moisture, heat, corrosion, etc., rational use of line types; and secondly to ensure the safety and quality of various types of electrical appliances, the line to ensure that in the case of electrical wiring can purchase and does not appear overload case; another line should be laid approached the road as much as possible, straight road, avoid circuitous.
