With the rapid development of society, the era of electrification has come quietly. Nowadays, household appliances, production appliances, and work appliances are full of corners of the world. There are so many silicone wires covering all aspects of daily life. But then, large-scale electrical fires with heavy losses came into being. Especially in recent years, with the rapid increase of various types of large and high-rise buildings, the huge internal electricity system is even more hidden. For the firefighting forces, who are tasked with heavy fire fighting, they have their own unique insights into electrical fires. After countless firefighting battles, electrical fires have given firefighters thrills and challenges. However, there are many officers and soldiers participating in the battle every year because they do not have enough experience. And the lack of awareness of personal protection and the serious consequences of being injured or even sacrificed in the battle, leading to the failure to complete the fire fighting mission.

Electrical fires are caused by electric sparks, electric arcs, electric heating radiation baking, exposure to high temperatures, static electricity, etc. The causes of the above ignition phenomenon are caused by short circuit, overload, poor contact, heat, improper grounding, and illegal use of electricity. These common problems seem to be simple, and a little carelessness will be like a dike of a thousand miles, collapsed in an ant nest. This requires understanding from the height of comprehensive prevention and rectification.

Some design units do not strictly follow the electrical installation design specifications and fire protection design specifications. The design drawings are unscientific and unreasonable, and even the backward products are still used in the design blueprints. There are many cases in which the protection components of the electric facilities in the low-voltage circuit are improperly selected, and are several times larger than the actual facility load, and cannot provide protection at all. For public entertainment places, the design drawings should indicate the use of flame-retardant pipe protection for the VDE silicone wire and cable; for inflammable and explosive places such as gas, fuel, and dangerous goods storage rooms in the building The power and lighting appliances are not designed to be explosion-proof, and the anti-static design is also quite weak.

After the design unit designed according to the specification, the construction unit did not strictly follow the relevant electrical construction specifications, and modified the design drawings; did not select electrical equipment and materials according to the design standards, randomly changed the line parameters or randomly connected the power supply to increase the load, such as replacing it with aluminum wires For copper wires, replace large wires with small wires, and replace flame-retardant wires with ordinary wires. Individual construction units are unqualified or low-qualified to undertake projects, especially the construction quality of some interior decoration construction units is worrying. These units integrate design and construction, one-sided pursuit of decoration effects in design, ignoring safety issues, and ignoring the provisions of relevant electrical professional design fire protection codes. There is a widespread problem that electricians do not pay attention to construction specifications during construction. The quality of small cross-section copper wire joints in electrical circuits is the key to preventing the circuit from contacting and heating and destroying the insulation and causing fire. The construction specifications stipulate that the joints must be brazed and tinned. And some electricians gave up this process and only spliced things by hand. Concealed projects, such as cutting corners, not piercing through pipes, bare conductors, unsealed Teflon wires and cables, messy wires in the ceiling, irregular electrical cabinets, no lightning protection grounding, and virtual connection of protective grounding conductors are still common.
