5 Tips for Using Non-Sparking Tools Safely
Non-sparking tools are those made without iron—that is, made from non-ferrous materials like brass, copper-nickel alloys, bronze, or copper-aluminum alloys. They may also be made of copper-beryllium alloys, but these present challenges because of the toxic nature of beryllium dust, which can be a carcinogen. Wood, plastic, and leather tools are also classed as non-sparking.
Be aware that “non-sparking” is something of a misnomer: non-sparking tools can produce “cold sparks” that don’t contain enough heat to cause carbon disulfide, the substance with the lowest ignition point, to catch fire. But you still may see sparks even when using non-sparking tools.
So if non-sparking tools are themselves a safety precaution, what other safety concerns could there be? Here are 5 tips for using non-sparking tools safely that may explain concerns when using tools made of non-ferrous materials:
Inspect for Wear
Non-sparking wrenches, chisels, hammers, crowbars, and other non-ferrous tools are softer than tools made with iron. As a result, they may become worn more quickly. A hammer, chisel, or wrench with a worn striking surface or handle can be a hazard. Ensure you inspect your non-sparking tools before each use and send worn ones to be redressed.
Eliminate Residue
It’s essential to keep non-sparking tools clean. Any tool can pick up dust or residue from the materials worked on, and these residues can cause sparking, even though the tool is made to avoid creating sparks.
Ensure Cross-Ventilation
Store non-sparking tools in an adequately cross-ventilated location to avoid moisture and dust build-up. An accumulation of dust can cause sparks and explosions in hazardous work areas where gases, vapors, or other flammable substances are present.
Don’t Use Copper With Acetylene
Acetylene reacts with copper to create explosive acetylides. Using copper in contact with acetylene in humid environments is especially hazardous as moisture increases the risk of reaction.
Rely on the User’s Manual
Different types of non-sparking tools are used for different applications. Read, re-read, and read the user manual again. Know how and where your specific tool may and may not be used safely. To use your tool safely, it’s also critical to understand your work environment and the composition of gases, vapors or other materials that are present, and what the user’s manual says about how your specific tool will react in that environment.
These 5 tips for using non-sparking tools safely should enhance safety in the work environment. Never become complacent about using non-sparking tools: vigilance with cleanliness and attention to cross-ventilation and wear are necessary at all times.
