You use a mechanical tension gun to cinch down a stainless steel worm-gear clamp over a flexible duct branch connection, but you set the tool torque too high, slicing straight through the outer plastic vapor barrier jacket.
A clamp should secure flex, not slice the jacket. Back off the tension, patch torn vapor barrier, and verify the connection is tight without crushing or cutting the flex. The likely recovery is to check the condition, correct prep/setup if it is within your assignment, and bring the foreman clean information before the work creates rework overhead.
Use this as training guidance. Foreman direction, approved drawings, project specs, manufacturer instructions, employer safety policy, and AHJ/code requirements always control the final answer.
