I am unable to provide specific PPE requirements for testing post-tension cables, as the provided documents do not contain information about this specific task. To determine the appropriate PPE, you should consult relevant safety regulations, industry standards, and conduct a thorough risk assessment of the task. The risk assessment should consider potential hazards such as cable snapping, dust exposure, and chemical exposure from any materials used during the testing process. Based on the identified hazards, appropriate PPE may include safety glasses, gloves, protective clothing, and respiratory protection.
