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 required:

• 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 danger of head injury from electric shock or burns due to contact with exposed 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 and Sleeves: Employees should wear rubber insulating gloves for protection against electrical hazards [2]. These should be inspected before each day's use for defects [3].

It's crucial to inspect all PPE before use to ensure it's in good condition [4]. Also, ensure that employees are trained in the proper use of PPE and safety procedures.
