How is a system safety check done?

• A. Visual inspection
• B. Tactile inspection
• C. Load test
• D. All of the above

Answer: (D)

A system safety check is thorough because it verifies both the condition of individual components and how the whole system performs under real use. Visual inspection catches obvious damage like cuts, fraying, corrosion, cracks, deformation, or missing parts. It’s the first line of defense to spot issues that are easily seen. But some problems aren’t visible on the surface. Tactile inspection involves feeling for roughness, stiffness, sharp edges, looseness, or subtle signs of wear that visual checks can miss, helping to detect internal or hidden defects. Finally, a load test puts the system under the actual or simulated forces it will experience, confirming that connections seat properly, hardware engages as intended, and there’s no slippage or unexpected failure when loaded. Because each method covers different failure modes, using all of them provides the most reliable safety verification.
