How to prevent fires
1,How to prevent electrical fires caused by
To prevent electrical fires,including the four aspects:First,the choice of electrical appliances,and the other is the choice of wire,and the third is to install and use,not to the unauthorized use of four high-power electrical appliances.Electrical appliances should be chosen on the brand-name manufacturers to produce qualified products,to comply with the provisions of the installation,use the Manual in accordance with the requirements,do not wire乱拉.Teaching must be used when a larger electrical power to ask a professional electrician to install a dedicated line,shall not be mixed with other electrical appliances at the same time.Are normally not power,it is necessary to cut off power supply.Here are some commonly used to prevent electrical fires:
(1) TV's fire prevention measures
Open for 4-5 hours of television will take off to rest a while,especially in high temperature season.
Not near the heat source,do not watch the television coverage of TV TV cover.
To prevent liquid or insects into the TV.
Outdoor antennas have a lightning protection devices and grounding facilities,with outdoor antenna television thunderstorm days,do not open.Do not watch the television to cut off power supply.
(2) Washing machine fire prevention measures
Do not let water electrical short circuit,not more than clothing or a hard object stuck boring machine electrical phenomena caused by fire resulting in fever.
Do not use gasoline,ethanol,electric washing the dirt.
(3) fire prevention measures refrigerator
High temperature heat sink refrigerator,do not put back in refrigerator flammable liquids.
Fridge not keeping flammable liquids such as ethanol,as the refrigerator starts producing sparks.
Do not use washing refrigerator,refrigerator components in order to avoid a short circuit ignited.
(4) cotton-padded mattress electric fire precautions
Do not fold so as not to damage wire insulation,causing a short circuit caused the fire.
Do not use electric blanket a long time,must be left off to avoid overheating in case of fire.
(5) of the fire prevention measures electric iron
High temperature electric iron can ignite the material in general.Therefore,it must be using an electric iron hand care,electricity should not be too long a time,must run out of power,heat insulation on the shelves of natural cooling,heat to prevent fire.
(6) PC's fire prevention measures
To prevent moisture and liquids into the computer to prevent the insects in the way of computer.
Computer time should not be too long,the cooling fan to keep air open window.
Do not contact the heat source to maintain good contact interface plugs.
Attention to eliminating the hidden dangers.Computer room electrical lines,and complex equipment,materials for flammability of materials,personnel gathered,mobility,management and other issues are potential confusion,there should be specific to the implementation of preventive measures.
(7) lighting the fire protection measures
The lamp switch,socket,lighting appliances near flammable materials should be to ensure that insulation,cooling measures.
When the current through the incandescent lamp can produce the high-temperature 2000-3000 degrees Celsius and luminous,as the light bulb filled with inert gas can be in thermal conductivity,so the temperature of the glass surface is also very high,the greater the power,the faster the temperature increase,incandescent and Fuel distance should be larger than 0.5 meters,light bulbs should not be put under the fuel.Learning to read at night,do not put blankets on the lighting.
2,How to prevent fires caused by smoking
Cigarette butts,though small,can be harmful,and its surface temperature between 200-300 degrees Celsius,the center temperature of about 700-800 degrees Celsius,the general fuel (such as paper,cotton,firewood,timber,etc.) are in the ignition,130 between -350 degrees Celsius,the temperature is below the cigarette butts,cigarette butts can ignite so most of the material,it can easily lead to throw cigarette butts fire.End tobacco smoking after cigarette butts should be "strangled",on an ashtray or metal,glass and other non-flammable equipment inside,do not arbitrarily throw,but can not ban smoking.
