If a rod breaks during operation, what safety step should be taken before handling it?

• A. Ensure all torque is out of it before handling it.
• B. Apply more torque to loosen it.
• C. Ignore and continue.
• D. Twist it to free it.

Answer: (A)

Eliminating stored energy before touching a broken rod is essential. When a rod breaks during operation, there can still be residual torque or other forms of energy in the mechanism that could release suddenly if you grab or move it. The correct safety step is to ensure all torque is out of it before handling it. This means isolating and de-energizing the equipment, releasing any stored forces in the system (such as hydraulic or pneumatic pressure), and applying lockout/tagout as needed so nothing can move unexpectedly. Taking these precautions prevents sudden movements, launches of fragments, or pinching injuries. The other options are unsafe because increasing torque, ignoring the situation, or twisting to free the rod can provoke further breakage, cause parts to eject, or put you at risk of serious injury.
