Both non-sparking and anti-static tools serve a critical role in preventing fires and explosions in environments where flammable materials are present. While they share this common goal, they are designed to address different types of risks. Non-sparking tools are crafted without ferrous metals like steel and iron, ensuring they won't generate sparks that could ignite under certain conditions. On the other hand, anti-static tools are engineered to work alongside grounding systems to prevent static electricity from reaching levels that could damage electronics or trigger a fire or explosion.

It’s worth noting that a tool can be both non-sparking and anti-static if it is properly grounded. For example, a non-sparking tool made from a copper alloy can effectively prevent electrostatic discharge when connected to a grounding system.

When Are Non-Sparking Tools Necessary?

Non-sparking tools are essential in facilities where there’s a potential for an explosive atmosphere due to flammable gases, mists, dusts, or liquids. Industries like oil refineries, paper mills, and ammunition plants often rely on non-sparking tools to ensure safety. Similarly, food processing facilities handling powdered materials such as milk powder, egg whites, or flour may also require these tools, as these substances can create combustible dust hazards.

What Makes a Tool Non-Sparking?

Non-sparking tools are primarily defined by their lack of ferrous metals. Materials like aluminum, copper, brass, and bronze are commonly used instead of steel or iron. Additionally, some non-sparking tools are made from non-metallic materials such as plastic, wood, or leather. Even though plastic tools are less likely to spark, there's still a possibility of what’s known as a “cold spark,” which doesn’t produce enough heat to ignite most flammable substances but can still look like a spark.

When Are Anti-Static Tools Needed?

Anti-static tools are crucial in environments where static electricity poses a risk, particularly around sensitive electronic components like motherboards. A static charge generated by a worker walking across a floor could easily damage an electronic component. In facilities where flammable gases like acetone or methane are present, even a small static discharge can lead to a fire or explosion.

What Are Anti-Static Tools?

Unlike non-sparking tools, anti-static tools are part of a broader system designed to manage static electricity. Static electricity accumulates through various processes, including tribocharging (when two materials rub together), electrostatic induction (when a charged object is nearby), and energetic particle impact (common in space exploration).

To prevent static buildup, facilities often implement an Electrostatic Discharge Protection Area (EPA). This involves grounding all conductive materials, ensuring workers are grounded, and avoiding highly charged materials. Anti-static tools are usually made from specialized plastics that maintain a balanced charge and low surface resistance, preventing them from accumulating or releasing static electricity.

These tools operate within specific temperature and humidity ranges. Using them outside these parameters could result in static accumulation, negating their protective benefits. At Vikan, our product line includes tools that meet non-sparking requirements, except for our metal-detectable options. Many of our tools are made from durable plastics, making them suitable for a wide range of environments. However, we do not currently offer anti-static tools.

Some of our products, such as our green shovels, incorporate static-resistant compounds to minimize static buildup and prevent materials from clinging to the tool. While this reduces static to some degree, these tools are not certified as anti-static and should not be used in environments requiring strict anti-static compliance.
