Wearing which kind of jewelry around energized equipment is considered hazardous?

Wearing conductive jewelry around energized equipment is hazardous because metals are good conductors of electricity. If a person wearing conductive jewelry comes into contact with an energized source, there is a significant risk of electrical shock or arcing. This can lead to severe injuries, including burns or even fatal accidents. Conductive materials like gold, silver, and copper can create a direct pathway for electrical currents, thereby increasing the danger in environments where live electrical components are present.

In contrast, non-conductive materials such as plastic do not pose the same level of risk, as they do not conduct electricity. This makes them safer options in environments where one might encounter energized equipment. Costume jewelry can also vary in composition, but often includes non-conductive materials and is usually not accepted in safety protocols due to potential entanglement risks rather than conductivity.

Understanding the properties of different materials and their interactions with electricity is crucial for maintaining safety while working near energized equipment.
