(2) How to prevent fire accidents?

1. Every teacher, student and employee in the school must first consciously abide by various fire laws and regulations and the school's fire safety management system to enhance their awareness of fire safety.

(1) Do not connect temporary wires without permission. Connecting temporary wires can easily lead to overload of power supply lines and fire;

(2) Don't use electric stoves, electric heaters and other electric heating equipment in public places such as dormitories. These electric heating devices consume a lot of electricity, which may easily lead to overload of power supply lines and fire.

(3) Do not use gas stoves, alcohol stoves and other stoves in public places such as dormitories. Because the dormitory is small and there are many flammable items, a slight negligence will cause a fire;

(4) Don't light candles and read books in the dormitory. It's too late to turn off the lights in the dormitory. If you are tired of watching too much wax and fall asleep, candles can easily ignite combustibles such as mosquito nets and cause fires.

(5) Smoking in bed, littering cigarette butts and match sticks. People are easy to fall asleep when lying in bed, and unburned cigarette butts or match stalks fall on combustible materials such as bedding, which is easy to cause fires;

(6) Don't burn sundries. When the fire left in the burning sundries is out of control, it is easy to cause a fire;

(7) Don't put the desk lamp near flammable materials. When the desk lamp is lit for a long time, the lamp holder is hot and close to combustible materials, which is prone to fire;

(8) Pay attention to the power failure when walking. When people leave the room, they should turn off the electrical switch, unplug the power plug and ensure that the electrical appliances are completely cut off.
