Fire prevention measures of microcomputer

Prevent moisture and liquid from entering the microcomputer and insects from crawling into the microcomputer.

The use time of the microcomputer should not be too long, and the cooling window of the fan should keep the air unobstructed.

Do not touch the heat source, and keep the interface plug in good contact.

Pay attention to eliminating hidden dangers. There are many and complicated electrical circuits and equipment in the computer room, and the materials are mostly flammable materials. Problems such as personnel gathering, high mobility and chaotic management are hidden dangers, and preventive measures should be implemented in a targeted manner.

Fire prevention measures of lamps and lanterns

When the switches, sockets and lighting devices of lamps and lanterns are close to combustible materials, heat insulation and heat dissipation measures shall be ensured.

Incandescent lamps can emit light at a high temperature of 2000-3000 degrees Celsius when current passes through them. Because the bulb is filled with inert gas to conduct heat, the temperature of the glass surface is also very high. The greater the power, the faster the temperature rises. The distance between incandescent lamp and combustible materials should be more than 0.5m, and combustible materials should not be placed under the bulb. When reading and studying at night, don't put the lighting on the bedding.

Prevention of fire caused by smoking

Although cigarette butts are small, they can be harmful. Their surface temperature is between 200-300 degrees Celsius, and the center temperature can reach about 700-800 degrees Celsius. The ignition point of general combustible materials (such as paper, cotton, firewood, wood, etc.). ) are between 130-350 degrees Celsius, which is lower than the temperature of cigarette butts, so cigarette butts can ignite most substances, so littering cigarette butts is easy to cause fires. After smoking, you should "strangle" the cigarette end and put it in an ashtray or nonflammable appliances such as metal and glass. Don't throw it about, and don't smoke in non-smoking places.
