1. General tips to follow strictly by non-sparking tool users
1.1 Non-sparking tools are safety products that should be selected with care. Prior to purchasing any of them, users should understand what are specified in their instruction manuals, including the range of product applications, performances, features, usages and precautions.
1.2 Before using the tool on a jobsite, operators should firstly identify its applicable atmospheres to ensure the tool is safe to use in those gas environments.
1.3 Non-sparking tools should not be used in non-risky environments in case they lose their original non-sparking properties.
1.4 It is safe to say that our non-sparking tool will retain high hardness and corrosion resistance in most of combustible gas applications. But this rule is not applicable to all of the cases. In damp, ammonia- or acetylene-laden environments or ammonium salt, fluorine, chrome, ammonia, and bichromate media, there still exists high possibility of corrosion damages to the tool.
Some media can react with copper alloy to create highly explosive gases, or copper acetylide in the case of acetylene environments. Therefore, when you use a non-sparking tool, use it in a dry environment. If a damp environment is unavoidable, you need to complete the work faster before it causes any severe corrosion that leads to unwanted danger. Clean the tool after use. Do not put it in the same box with other corrosive substances.
1.5 Each non-sparking wrench has a rated hardness that specifies a use limit. For this reason, users are not allowed to add any steel tubes to the handle for use in any overload applications. Users must not use a hammer to strike a wrench in case it would cause the hammer to deform or break, with the exception of a striking wrench.
According to specific job need, users need to choose the most appropriate tools. Do not choose a size that is either smaller or bigger than is required. Neither should users use the non-sparking tools in a non-risky environment, as with the ordinary steel tools. It is worth noting that when users operate the adjustable wrench, pipe pliers or box-end wrench, cares should be taken not to turn the tool in any improper directions.
When using a blade tool on the workpiece, users first need to measure the hardness of workpiece. If its hardness only approaches rated capacity of the cutting tool, then it is safe to use the tool. If its hardness exceeds that of the cutting tool, do not use that cutter. When the workpiece is tightened or fixed permanently or corroded, users should take precautions to protect the tool in case it will be damaged.
1.6 When the tool is unused temporarily, clean it as soon as possible. If it will stay unused for more than six months, apply lubricating oil to its surface or store it in a way that protects against corrosion. For tools that will be sitting unused over a year, apply lubricating oil to them or put them in a carton for storage. Some tools may suffer from wearing out or damage, especially the cutting tools. If so, repair them in a non-risky environment. Tools that suffer from severe damages should go to scrap. Do not use a severely damaged tool.
2. Tips to follow strictly when using the tool in typical applications
Listed below are two cases where sparks are not created by our non-sparking tool but caused by the workpiece itself. In such cases, using non-sparking tools does not eliminate the risk of potential explosion. For this reason, other explosion prevention measures should be taken.
2.1 There is still a possibility of sparks when the non-sparking tool collides with rocks. In such cases, the spark does not come from the metal but the rock. When under stress, the rock would crack, transforming the mechanical energy into electrical energy that is released in the form of electrical sparks. Sparks are easily triggered in rocks that contain quartz, silica, and sandstone. Generally speaking, the higher quartz composition or larger quartz granules a rock has, the more likely it is for a rock to be triggered. To protect against accidental explosions, users can submerge the rock into the water before any operation is possible.
2.2 Sometimes the non-sparking tool needs to cope with aluminum-coated hot steel workpiece including the pipes, hot containers, bolts, and nuts. The impact or intense friction between the tool and workpiece might generate sparks that ignite the explosives. In another case, there might be aluminum, magnesium or Al-Mg alloy particles adhering to the rusted steel surface. When struck by hard objects or even hard rubber or plastic, a thermite reaction might be triggered which releases a large amount of heat that can directly ignite the explosives.
3. Features of Beryllium Copper Tools
3.1 Made of military materials mixing with noble metals, the beryllium copper tool is a world widely accepted non-sparking product that usually comes in the color of gold.
3.2 Its surface hardness varies between HRC30 and HRC40 with its tensile strength ranging between l05 kgf/mm2 and 120kgf/ mm2. This series of product meet the GBEx IIC standard. Other technical specifications are on par with the international standards.
3.3 This type of non-sparking tool is suitable for use in environments with a hydrogen concentration below 21%. Its non-sparking nature allows the tool to operate in a constant, fast motion without stop, as it does not create any sparks from impact or friction that might cause ignition of hydrogen gas.
3.4 The non-sparking Be-Cu tool is also non-magnetic. It can be exposed to a strong magnetic field.
4. Features of Aluminum Bronze Tools
4.1 Yellow-grey in color, the Al-bronze tool is made with noble metals.
4.2 The product meets the GBEx IIB standard, with a surface hardness reaching HRC20-30 and tensile strength varying between 75 kgf/mm2 and 85kgf/mm2. All other technical specifications of this product are on par with related international standards.
4.3 This tools safe to use in explosive atmospheres where the ethylene concentration is below 7.8%, provided that users operate the tool in strict accordance with the regulations listed in the instruction manual. It does not generate any sparks from impact or friction between metal-to-metal contacts that might ignite the ethylene gas.
5. Non-Sparking Tool User Guide
5.1 Before each time of use, wipe the grease or dirt off the tool surface.
5.2 After use, clean off the filthy deposits on the tool surface. Store the tool in a dry and cool place. Make sure the tool is not stored in the same room with corrosive substances.
5.3 The striking tool should not be used to do more than ten times of pounding actions without stop. At the start of each pounding action, users need to clean off the sticky scraps or rust deposits adhering to the striking surface before any later action is possible.
5.4 The wrench should not be used beyond its rated capacity. Users are not allowed to add steel tubes or bind bar stocks to the wrench handle for extra leverage. Neither should you use a hammer to strike the wrench to tighten or loosen the fastener.
5.5 Cutting tools should be placed in the water channel and touched lightly to the abrasive wheel for grinding. Do not hold the cutting blade too tightly against the grinding wheel or keep them in physical contact for a long time.
5.6 Practical use of hammer dictates the job site should be cleared and corrosive oxides on the tool surface removed. This can prevent foreign matters joining in the pounding action.
5.7 The non-sparking tool should be used with care. Users must not drop the tool freely on the rock or cement floor.
5.8 When dealing with rocks, users need to submerge them in the water before using the hammer to strike them.
