Concrete and Masonry — Post-Tensioning
Construction · Ver en español
Talking points
- Post-tensioning involves stressing steel strands or tendons to extremely high forces. A strand that breaks or releases can travel hundreds of feet at lethal velocity.
- No workers may stand behind stressing jacks during tensioning operations. The area behind the jack must be barricaded and cleared.
- Follow the engineer's stressing sequence exactly. Out-of-sequence tensioning can cause uneven forces that lead to structural failure or strand blowout.
- Inspect anchorage hardware before tensioning — damaged wedges, cracked bearing plates, or misaligned strands can cause failures under load.
- After tensioning is complete and strands are cut, the remaining tail must be protected to prevent contact injuries from sharp wire ends.
Ask the crew
Is the barricade set up behind all stressing jacks, and does everyone know to stay out of the strand path?
Standards this talk is built on
A toolbox talk is a short safety briefing. It supports the training a standard requires; it does not replace it.
