Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

Which method is NOT advised for removing excess material with hand tools?

1. Using a file

2. Using a chisel

3. Using a hammer

4. Using a lock-out procedure

The correct answer is: Using a lock-out procedure

Using a lock-out procedure is not advised as a method for removing excess material with hand tools because it serves a different purpose related to safety. Lock-out procedures are put in place to ensure that machinery or equipment is properly shut down and inoperable during maintenance or servicing to prevent accidental startups that could cause injury to workers. In contrast, the other methods listed—using a file, using a chisel, and using a hammer—are all legitimate hand tool techniques employed for material removal. Each of these tools is designed specifically for shaping or trimming excess material in various applications, making them suitable for tasks that require precision and control. Lock-out procedures do not apply to the actual act of material removal; rather, they are critical for safety management in the workplace involving machinery operations.
