ã€Overview】
The gas cutter operation method refers to a method of operating a gas cutter at a disaster site to cut a metal obstacle and rescue the trapped person to rescue or open a rescue channel.
Gas cutters use flammable gases (usually acetylene) and oxygen to cut metal equipment. Operators must have the required qualifications for practice.
(The name of the gas cutter and the operation of the operating line) Article 61 Â The operating lines for the names and operation of each part of the gas cutter are shown in Figs. 15 and 16 . |
ã€purpose】
The purpose of this article is to illustrate the name and operation of the various parts of the gas cutter.
(Importance enforcement precautions) Article 62 Â Â In addition to the provisions of Article 4 , when using gas cutters, the following should also be noted. First, it is forbidden to cut containers with residual gases and use them in a closed environment. Second, it is forbidden to use in places where there are flammable gases, liquids, steam and dust. Third, when the ignition, pay attention to stay away from the crowd. Fourth, pay attention to check the ignition port is blocked, the cutting gun condition is normal. 5. The rubber tube should be placed in the opposite direction from Mars in the cutting operation. Six, must be equipped with fire fighting equipment. |
ã€purpose】
In addition to the provisions of Article 4 , this article also specifies other precautions when using a gas cutter. The commander must pay attention to the provisions of Article 5 .
[Details]
1. It is forbidden to cut containers with residual gases and use them in a confined environment. Pay attention to ventilation and ventilation when operating.
Second, it is forbidden to use in places where there are flammable gases, liquids, steam and dust. When cutting operations have to be carried out in such places, fireproof materials must be laid within the range where Mars may splash.
Third, use a dedicated igniter to ignite. When igniting, pay attention away from the crowd.
Fourth, when installing the pressure regulator, attention should be paid to removing the dust at the ignition port to prevent clogging and prevent the cutting gun from leaking.
5. Do not place the cutter in the ignition state. Since the Mars generated by cutting will cause the rubber tube to be damaged, be careful not to drag the rubber tube, and the hose cannot be placed in the same direction as the Mars splash generated by the cutting. In case of emergency, fire extinguishers or other fire-fighting measures should be deployed.
