I wasn't able to find specific documentation in our current safety knowledge base regarding mandatory PPE for safe handling and testing of post-tensioning cables. However, here is some general safety guidance based on industry standards and best practices for electrical work:

When working with electrical equipment, including post-tensioning cables, it is essential to wear appropriate personal protective equipment (PPE) to minimize the risk of electrical shock, burns, or other injuries. The specific PPE required may vary depending on the nature of the work and the voltage levels involved, but generally includes:

• Insulated gloves: These protect hands from electrical shock and should be rated for the voltage levels expected.
• Protector gloves: These should be worn over the insulated gloves.
• Non-conductive head protection: Hard hats protect against head injury from electric shock or burns due to contact with exposed energized parts.
• Eye and face protection: Safety glasses or face shields protect against electric arcs, flashes, or flying objects resulting from electrical explosions.
• Insulated tools: Use insulated tools and handling equipment to prevent contact with energized conductors or circuit parts.
• Appropriate clothing: Wear clothing made from non-conductive, flame-resistant materials.

Always inspect PPE before use to ensure it is in good condition and free from defects. Use equipment that has been tested in accordance with the requirements. It's also important to ensure that the equipment is clean and stored properly to protect it from damage.
