Explosion-proof tool is a special tool for safety, which has the characteristics of not generating sparks when colliding and rubbing with other tools in a special environment. Most explosion-proof tools are steel tools or evolved from steel tools, and the materials are made of multi-element non-ferrous metals based on copper, and some are specially designed according to requirements. For this special tool that is different from other metal tools, there are certain requirements for the method of use, maintenance, storage, and transportation. In this way, the service life of the tool can be better extended. When purchasing explosion-proof tools, you should carefully understand the scope of adaptation, performance, characteristics, methods of use, and precautions specified in its manual. The tool body is usually marked with an "Ex" mark, which is a qualified product. Never buy such products without a certificate, otherwise, it will cause personal injury in future use.
Before using explosion-proof tools, compare the combustible gas in the workplace with the explosion-proof test gas; products that have been tested with higher-level media can be used in media sites with lower levels of danger. Conversely, products that pass the test of lower-level media cannot be used in locations with higher levels of danger. In addition, if there are special requirements, the relevant professional department should be asked to test. For special occasions, you can contact the manufacturer to customize your own explosion-proof tools.
Explosion-proof media are not corrosion-resistant in all cases. For example, in damp ammonia, certain ammonium salts, acetylene, damp fluorine, chlorine, chromium ammonium, certain dichromates, potassium hydride, etc. The degree of corrosion is considerable. Moreover, some media will also undergo chemical reactions after contact with copper alloys, generating highly dangerous explosive substances, such as acetylene steel formed by the combination of acetylene and steel. In the above situation, use explosion-proof tools in a dry environment as much as possible. If it is impossible to avoid use in a humid environment, try to speed up the operation speed, and reduce the working time to avoid the risk of causing large corrosion. Wipe clean after use in time, it is strictly forbidden to store together with corrosive media.
All types of wrenches of explosion-proof hand tools have different rated strengths. It is strictly forbidden to use casings for overloading. Except for knocking wrenches, they must not be knocked, so as to avoid breaking and deformation due to overload and affecting normal use. In the process of using the tool, the variety and specifications should be reasonably selected according to the needs. It should not be small and large, and it should not be treated like a steel tool. It should also be pointed out that when using a spanner, pipe wrench, or open wrench, Pay attention to the requirements of the direction of the force, and do not apply any force in reverse. When using a tool with a blade, the hardness of the workpiece itself should be measured first. If the hardness is close to the hardness of the tool, it should be carefully operated. If it is higher than the hardness of the tool, it is prohibited to use it. When the workpiece is tightened by motor, semi-permanently fixed, or due to long-term rust, and no other measures are taken before using the hand tool, the user should be prohibited to avoid damage to the tool.
After the explosion-proof tool is deactivated, wipe it off in time. Those who do not use it within half a year should be oiled or preserved by the anti-corrosion method. Those who have been out of use for more than one year should be oiled and put into bags or boxes for storage. Some parts of the used tools are naturally worn or damaged, especially those with blades. It can be repaired in non-hazardous locations. If the tool has been severely damaged, it should not be used.
