What method can effectively prevent static electricity from being an ignition source?

Using non-conductive pads is an effective method for preventing static electricity from becoming an ignition source because these pads are specifically designed to reduce or eliminate the buildup of static charges. Non-conductive materials do not allow the free flow of electric charge, which helps to mitigate the risk of static electricity. By incorporating these pads into environments where there is a potential for static discharge, such as in electrical work or areas where flammable materials are present, the chances of an ignition source developing due to static electricity are minimized.

This approach is particularly crucial in environments that handle sensitive electronic components or flammable substances, as static discharges may not only ignite vapors but can also damage electronic parts. The use of non-conductive pads acts as an insulator and serves to dissipate any static charge, creating a safer working environment.

The other methods presented, while they may contribute to overall safety, do not directly address the management of static electricity in the same way. For instance, while maintaining a dust-free workspace can help minimize fire hazards, it does not inherently reduce the risk of static buildup.
