Question: During a concrete pour for a residential foundation wall, a section of the formwork begins to bulge noticeably. The pour height is approximately 1.5 m from the bottom of the form. What is the most immediate and appropriate action the carpenter should take?
Answer options:
- Continue the pour at a reduced rate and monitor the bulge ✅ Immediately stop the concrete pour in that section and notify the supervisor
- Attempt to strengthen the bulging section with additional bracing while pouring continues
- Increase the vibrator usage in the bulging area to consolidate the concrete
Correct answer: Immediately stop the concrete pour in that section and notify the supervisor

The immediate and safest action is to stop the pour in that section to prevent a catastrophic blowout, which could cause injury or significant material loss.
