While the provided documents do not explicitly list the required PPE for testing post-tension cables, they do offer general guidelines for electrical safety and personal protective equipment. Here's a summary of what would likely be relevant:

• Electrical Protective Equipment: If there are potential electrical hazards, employees must use electrical protective equipment appropriate for the body parts needing protection and the work performed [1]. This equipment must be maintained in a safe, reliable condition and inspected/tested periodically [1].
• Head Protection: Nonconductive head protection should be worn where there's a risk of head injury from electric shock or burns due to contact with energized parts [1].
• Eye and Face Protection: Protective equipment for the eyes or face is necessary where there's a danger of injury from electric arcs, flashes, or flying objects resulting from electrical explosions [1].
• Insulated Tools: When working near exposed energized conductors or circuit parts, insulated tools or handling equipment must be used if there's a chance of contact [1].
• Insulating Gloves: Employees should wear insulating gloves when handling cable suspension strand which is being installed on poles carrying exposed energized power conductors [2].

It's important to inspect all personal protective devices, tools, and equipment before each day's use to ensure they are in good condition [3].

To ensure full compliance, consult relevant safety regulations and standards, such as WAC 296-24-980 [1] and WAC 296-800-160 [1], and consider consulting with a qualified safety professional.
