Final answer:
When working with the H-53E, a grounding wand and insulated gloves with a minimum protection of 20,000 volts should be used to ensure safety from electrical hazards.
Step-by-step explanation:
The static discharge device (grounding wand) and insulated gloves, with a minimum of 20,000 volts protection, shall be used when working with the H-53E. It is important to use appropriate safety equipment to protect against electrical hazards when working on or near electrical systems, such as those found in aviation. The H-53E refers to a type of helicopter, likely implying maintenance or repair work that involves exposure to electrical components or static electricity risks. Reference to standards or guidelines specific to aircraft maintenance would be the context from which this voltage protection level is derived, ensuring that technicians are insulated against the potential build-up of static electricity that could cause damage or injury.
