1.1 Safety Tool is a safe protective equipment, the user must purchase approved by the state-proof performance test detection and identification of qualified products when the purchase should seriously understand the scope of application, performance, features, uses and precautions required by the specification. 1.2 proof tools before use to identify gas sites, tools used to determine whether the proof performance. 1.3 proof tools should not be treated as a non-hazardous location arbitrary use common tools, in order to avoid losing its proper performance. 1.4 Explosion tool in most flammable gases is a high strength, corrosion-resistant. However, not all corrosion in all cases, as in the wet ammonia, acetylene, some ammonium salts, fluorine, chlorine, chromium ammonium dichromate some media, the degree of corrosion is considerable. Some media and copper alloys occurs after exposure to a chemical reaction to produce highly dangerous explosive substances, such as acetylene and acetylene copper compounds copper. Therefore, when using explosion-proof tools, as far as possible in a dry environment, such as possible to avoid the use in a wet environment, to try to speed up the operation speed and reduce working hours to prevent corrosion caused by large and dangerous. Wipe clean after use at any time, and non-corrosive substances and fitted with a box. 1.5 Explosion hand tools all kinds wrenches, have a different rated strength, non-cased overload, in addition to other tools can not tap wrench tap outside, in order to avoid fracture and deformation due to overloading, affecting the normal use. When using the tool in a reasonable choice of different specifications according to their needs can not be a small generation of large, but not to make it the same as a steel tool use. It should be noted that the use of wrenches, pliers, wrenches time, pay attention to the direction of the force requirements, shall be arbitrarily knob, using the tool with a blade, first measuring the hardness of the workpiece itself, when its hardness close Tools hardness and can be operated, when it is harder than tool hardness is prohibited. When the workpiece is fastened by a motorized, semi-permanent mounting or corrosion, and before using hand tools do not take other measures should be banned, in order to avoid damage to the tool. 1.6 Safety Tool disabled, should be ready to wipe clean. Within six months should not oiled or saved with the antiseptic method, more than one year should be oiled disable load-generation or box store. For tools used some natural and some parts of wear or damage, particularly edged tool that can be trimmed non-hazardous location. A damaged badly worn not repair themselves, should be scrapped, the job can not be sick.
