Fire caused by improper decoration and decoration is one of the main causes of home fires. Among them, 30% of fires are caused by old residential electrical lines or improper construction. Therefore, the fire protection of electrical lines cannot be neglected in the home improvement process.
1, home decoration commonly used wire and cable
Power wires: Power cables have an insulating layer on the outer conductor and are mainly used to send, distribute, and transport household electricity. The power cords commonly used in homes should use BW2×2.5 and BW2×1.5 models. The BW2×2.5 type wire is generally used as the main line for the home socket wiring, and the BW2×1.5 type is the branch line for the lighting line.
Communication cable: It is mainly used to transmit audio, analog signals of 150kHZ and below, and digital signals of 2048kbit/s and below. The common communication cables at home are audio cables, telephone lines, and network cables.
2, the purchase of wire and cable
The right choice of wire and cable can guarantee the safety of electricity at home, and the same goes for the decoration process. Therefore, there are two points to note when choosing a wire and cable.

3, purchase method
Eyesight: observe the appearance of color.
Hand touch: appearance is round and smooth

Hand touch: check for damage
3, wire and cable fire precautions
In the home improvement process, if the improper use of wire and cable, or the choice of poor or old wire and cable, it is easy to cause fire. Therefore, attention must be paid during the construction process to the storage of materials and the construction process.
1) How should the wire and cable be handled?
In the renovation site, it is necessary to avoid breaking up the coiled wires and cables and keep away from the open flame. It is also not appropriate to expose wires and cables directly to sun exposure or ultra-high temperatures, especially for construction wires.
Installed wires must be jacketed with plastic or metal tubes to protect them from human damage. For wires laid on ceilings, walls, etc., there must be no wire connections in the pipeline.
2) How to deal with fire on wires and cables?
First, cut off the power supply, and then select an uncharged fire extinguisher to extinguish the fire, such as dry powder, carbon dioxide, 1211 fire extinguisher, avoid using foam fire extinguisher. Pay attention to the safety distance between people and fire-fighting equipment and live objects during the extinguishing process. When extinguishing aerial wires, the elevation angle between the average person and the electrified body should not exceed 45° and they should stand on the outside of the line to extinguish the fire.
Xiao Bian's message: Many living examples always remind us of the importance of fire prevention at home. Especially in home renovations, many still materials are used. If the material is selected and constructed improperly, it is easy to cause fire.
There are many kinds of protective gloves. In addition to chemical resistance, there are also anti-cutting, electrical insulation, waterproof, cold resistance, thermal radiation protection, fire retardant and other functions. It should be noted that the general acid and alkali resistant gloves are not the same as the chemical resistant protective gloves. So when needed, you should choose protective gloves that prevent all kinds of chemicals from penetrating.
The correct use of
1. Check whether the gloves are damaged before each use
2. Wear protective gloves before handling harmful substances or operating dangerous procedures
3. Avoid exposure of pollutants and contact with the skin after removing the contaminated gloves
4. Contaminated gloves should be wrapped before being discarded
5. Reuse protective gloves should be thoroughly cleaned and air-dried after use
6. Choose gloves of the right size
Maintenance method
1. Put protective gloves in a dry, dark and constant temperature environment
2. When there are a large number of chemical substances remaining, use appropriate solvent to clean, but avoid using corrosive cleaning fluid
3. Dry the gloves thoroughly after washing. Do not use heat to dry the gloves unless instructed by the manufacturer, as it will age the gloves quickly
Proper use and maintenance can properly increase the service life of protective gloves.
