Why should safety devices not be modified or bypassed on equipment?

• A. They do not affect performance
• B. Modifications can disable protective functions, increasing injury or damage risk
• C. They are optional
• D. They speed up maintenance

Answer: (B)

Safety devices exist to prevent harm by stopping dangerous actions or limiting exposure to hazards. Modifying or bypassing them removes the built-in protection, which can disable the protective function and significantly raise the risk of injury or equipment damage, especially if a fault occurs or a dangerous condition develops. For example, guards, interlocks, or emergency stops are designed to keep you safe or to shut everything down quickly if something goes wrong; removing or bypassing them means a fault could go unchecked and a minor issue could become a serious incident. That’s why the correct choice states that changes can disable protective functions and increase risk. They are not optional, and bypassing them does not speed up maintenance; it can create greater risk and potential liability.
