Prior to commencing a post-tensioning operation, several safety procedures and critical items must be reviewed and verified. These include ensuring that all personnel involved are adequately trained, that the stressing equipment is thoroughly inspected, and that appropriate safety measures are in place to protect workers and the public.

Key areas to review and verify include:

• Personnel Qualifications and Training: Ensure all workers are trained by a qualified person in the hazards, procedures, and equipment related to post-tensioning activities.
• Site Access and Layout: Verify adequate access roads and a firm, graded area for safe equipment operation and material storage.
• Concrete Strength: Confirm written documentation that the concrete has achieved the minimum specified compressive strength.
• Equipment Inspection: A competent person must inspect stressing equipment for damage or defects before and during operations.
• Calibration Adequacy: Stressing equipment calibrations must be available on site and verified by a competent person.
• Fall Protection: Ensure employees placing or tying reinforcing steel more than 6 feet above an adjacent surface use a personal fall protection system.
• Safe Work Platform: Provide a work platform with guardrails and toeboards, kept clear of debris, for stressing tendons above grade.
• Restricted Access: Implement signs and barricades to limit access to the stressing area to essential personnel only.
• Emergency Preparedness: Review emergency action plans, including evacuation procedures and communication protocols.
