Type 1 rubber-insulating gloves are specifically designed for protection against live electrical work at certain voltage levels. According to ASTM D 120-09, these gloves are rated for use on systems that operate at voltages up to and including 50 volts. This rating means that when working on or near live electrical components, it is critical to use gloves that can provide adequate insulation against accidental contact with energized parts.

Using gloves rated for 50 volts ensures that workers are protected from the risks of electrical shock that can occur when working with or exposed to electrical systems at or above the specified voltage level. The requirement to wear Type 1 gloves becomes more crucial as the voltage levels increase, given that higher voltages come with greater risks.

Therefore, the choice that states 50 volts aligns perfectly with the standards set forth in ASTM D 120-09, emphasizing the importance of proper personal protective equipment in maintaining safety during electrical work.
