Question

why is it unacceptable to use a powder-actuated tool to fasten a plywood sheet to a wall stud?
a. the fasteners are too short to fasten the plywood properly
b. the booster is too weak to allow effective fastening.
c. the fastener can easily pass through both materials, causing an injury.
d. the fastener cannot penetrate plywood.

Explanation:

To determine why using a powder - actuated tool to fasten plywood to a wall stud is unacceptable, we analyze each option:

• Option A: Fasteners for powder - actuated tools are designed for specific tasks, and the issue of being too short is not the main safety - related reason for not using them on plywood and wall studs.
• Option B: The booster's strength is not the key factor here. Powder - actuated tools have boosters suitable for their intended uses, and this is not the reason for the unacceptability in this context.
• Option C: Powder - actuated fasteners have enough force. The problem is that when fastening plywood to a wall stud, the fastener can easily go through both the plywood and the stud (and potentially beyond), which poses a significant injury risk. This is a safety - related reason that makes this use unacceptable.
• Option D: Powder - actuated fasteners are capable of penetrating plywood, so this statement is incorrect.

Answer:

C. The fastener can easily pass through both materials, causing an injury.
