How to prevent fires caused by the use of single head electric heating tubes and heating electric heating tubes?
Electric heater is a commonly used device in work and daily life. Due to its resistance wire being made of nickel and chromium alloys, the temperature can reach over 800 ℃; In addition, electric heaters have relatively high power, so users must pay more attention to safety when using them to avoid accidents such as burns or fires.
From past cases, there are various possibilities for electric heater fires. One is to place the powered electric heater on or near flammable materials, causing fires under prolonged high-temperature baking; Another type is that the electric heater is not equipped with a plug and the wire head is directly inserted into the socket, which can easily cause a short circuit and lead to a fire.

If the plug is not unplugged in time when using the electric heater, it can overheat and ignite nearby combustibles, causing a fire. In addition, if the resistance wire of the electric heater is repaired multiple times and continues to be used, it can cause overloading of the circuit and cause a fire.
So in order to improve the safety of using electric heaters, flammable and explosive materials should not be placed near the electric heater, and a certain safety distance should be maintained; Secondly, the electric heater needs to be placed on a non conductive and non combustible material base; The safe cut-off flow rate of the three electric heater wires needs to meet the capacity requirements of the electric heater, and industrial electric heaters must be equipped with separate circuits under any circumstances.
The wires of the four electric heaters need to be installed with plugs, and the wire ends of the electric heater cannot be directly inserted into the socket; Timely replace aged or damaged circuits; Install a disconnection container for the equipment, and ensure that someone is watching over it during use. When leaving, unplug the plug. In the event of a power outage, the electric heater plug should also be unplugged in a timely manner and not forgotten.
For resistance wires that have been repaired multiple times, they should no longer be used and replaced with new ones; All kinds of flammable and explosive materials are strictly prohibited from being dried with electric heaters; The seventh is about the temperature setting of the electric heater, which should not only prevent excessive temperature but also prevent the electric heater from baking for too long.
