In electrical work, insulated tools and gloves shall be worn for voltages exceeding what value?

In electrical work, insulated tools and gloves shall be worn for voltages exceeding what value?

• A. 120V
• B. 240V
• C. 480V
• D. 600V

Answer: (A)

Insulating tools and gloves are used to create a dielectric barrier that reduces the chance of electric shock and limits arc flash risk when you’re working near live conductors. The guideline used in many CWEA electrical safety contexts sets 120 volts as the threshold above which insulated protection is required. Once the voltage exceeds 120 V, the potential danger from shock or arcing becomes significant enough that wearing insulated gloves (rated for the voltage) and using insulated tools (also rated for the voltage) is necessary to protect you. The other voltages listed are higher, but the rule is defined at 120 V, making that the correct threshold. Remember to choose gloves and tools appropriate to the voltage and to inspect them before use.
