The use of safety hand tools should be a key component of most industrial safety programs&period; An understanding of the hand tool's intended use and environment&comma; combined with proper tool selection&comma; maintenance and storage&comma; will greatly reduce the risk of explosion and fire&period;

We offers the following common-sense guidelines for Tool Use&comma; Maintenance and Storage&period;

• Keep non-sparking tools clean and free from ferrous or other contaminants&comma; which may impair the non-sparking properties&period;
• Do not use non-sparking hand tools in direct contact with acetylene&comma; due to the possible formation of explosive acetylides&comma; especially in the presence of moisture&period;
• During normal use&comma; all hammers and chisels will progressively develop some damage to the striking faces of hammers or the cutting edge and striking end of chisels&period; As part of the normal operating and safety procedures&comma; these tools should be returned to the workshop&comma; as with steel tools&comma; to have the faces and heads redressed&period; This is essential to prevent eye damage resulting from chips detaching from the item during use
• Do not store hammers and other hand tools fitted with wooden handles in places where the handles may dry out and shrink&period; This will increase the risk of the handle breaking or the head becoming loose
• Avoid overstrikes&comma; causing damage to the shaft&period; Supply replacement handles are often available from the manufacturer&comma; and should be fitted by a competent operator&comma; using an approved method of fitting and paying particular attention to the fitting of the wedges
• Fiberglass handles can offer advantages over wooden handles in terms of breaking stress and tolerance for adverse environmental conditions&period; Fiberglass shafts fail progressively&comma; rather than catastrophically&comma; reducing the risk of sudden failure&comma; injury or damage&period;
• When selecting a wrench&comma; the jaw opening should have a close and tight fit on the head of the nut or bolt to which it is being applied&period; This is especially true with non-sparking tools&comma; as they typically do not have the hardness of steel tools&period;
• Tools are designed for specific use&period; As with any tool&comma; additional torque should not be applied through the use of "cheater bars&period;" In addition to the probability that the tool will be damaged&comma; this is a dangerous practice for the safety of the operator&period; Wrenches should not be used as levers&semi; nor screwdrivers as chisels&comma; and so on&period;
• The accepted standards of safety and maintenance for common steel hand tools must also be adopted with non-sparking hand tools&comma; in addition to any specific recommendations resulting from the alloys used&period;
• When sharpening non-spark safety tools&comma; follow normal safety procedures&comma; such as the provision of eye and face protection&comma; adequate extraction and dust collecting facilities&period;
