What protective measure is required for containers from overhead electrical wiring?

The requirement for protective covers for containers from overhead electrical wiring is crucial to ensure safety in the workplace, especially when dealing with flammable materials like compressed natural gas. Protective covers serve as a physical barrier that helps prevent contact between the containers and any overhead electrical components, thus reducing the risk of electrical hazards such as shocks or fires caused by accidental discharge or arcing.

While insulation materials might provide some level of protection against electric shock, they may not effectively prevent physical contact with overhead wiring. Extension poles are not a protective measure for containers; rather, they are used for reaching high areas, which does not address the risk of electrical interference with the containers themselves. Grounding straps are essential for preventing static electricity buildup and providing a path for electrical discharge, but they do not serve to protect against the hazards related to physical contact with overhead electrical components.

Overall, protective covers are specifically designed to create a shield, ensuring that containers remain safe from any electrical overhead hazards.
