The sharp tail has a variety of uses.

Follow the guidelines below to reduce the risk of explosion and fire.

· Make sure all “non-sparking” tools are kept clean and free from ferrous or other contaminants, which may hamper the non-sparking properties.

· Select the right sized tool for the task (such as the wrench opening to the nut). The right fit will help prevent the tool from slipping, reducing the chance of a spark.

· Do not use non-sparking hand tools in direct contact with acetylene, which may form explosive acetylides, especially in the presence of moisture.

· Use local or mechanical ventilation systems as appropriate to remove hazardous materials, dusts and vapors from the workplace.

· Non-sparking tools will need to be redressed more often. Follow normal safety procedures when sharpening non-sparking tools such as the provision of eye and face protection, adequate extraction and dust collection facilities.
