The intent of machine guarding includes preventing injuries from machine malfunctions, in addition to preventing contact with the machine and flying chips or sparks. Which option best reflects this broader scope?

• A. All of the above
• B. Only contact with the machine
• C. Only flying chips
• D. Only malfunctions

Answer: (A)

The main idea is that machine guarding is meant to protect workers from the full range of hazards machines can pose, not just one aspect. Guards must prevent direct contact with moving parts, contain or direct flying chips or sparks, and guard against injuries that can happen if a machine malfunctions—such as unexpected start-up, loss of control, or an energy release. If a guarding solution only addressed contact, it would still leave workers vulnerable to flying debris and to injuries during malfunctions. Therefore, the best choice is the one that acknowledges all these hazards, reflecting the complete protective purpose of guarding. In practice, this is achieved with barriers and enclosures, chip shields, interlocks that stop the machine when guards are opened, and energy-control measures to manage malfunctions.
