For electrical hazards, safety-toe shoes must be nonconductive and protect against how many volts in dry conditions?

Safety-toe shoes that protect against electrical hazards must be nonconductive and are required to withstand up to 600 volts in dry conditions. This standard is crucial for workers exposed to electrical risks, as it significantly reduces the risk of electric shock. The shoes' nonconductive nature prevents electricity from passing through the shoe to the ground, thereby providing essential protection when working around live electrical equipment or wiring.

Understanding why 600 volts specifically is a standard also relates to the general voltage level encountered in many industrial and construction settings, making it a practical requirement for ensuring worker safety. Other voltage levels listed in the choices, such as 1,000 volts, may refer to different safety categories or requirements but do not reflect the typical minimum standard for electrical hazard protection in nonconductive footwear.
