Secondary containment is required for glove-bag removal when removing more than how many square feet or linear feet on a pipe?

• A. When removing greater than 3 square feet or 3 linear feet on a pipe
• B. When removing any amount from a non-metal pipe
• C. When removing debris from the work area
• D. When removing more than 1 square foot from any component

Answer: (A)

When removing material from a pipe with a glove bag, you’re working to control potential fiber release, so a secondary containment barrier is added for larger removals. If the amount being removed exceeds 3 square feet or 3 linear feet along the pipe, secondary containment is required to catch any fibers or debris that could escape the bag and to keep the work area contained during cleanup. This extra layer is not needed for smaller removals, where the glove bag alone typically suffices. The other choices don’t fit because they don’t specify the pipe-specific measurement threshold of more than 3 square feet or 3 linear feet.
