The proper procedure for inspecting chains during a semi-annual inspection involves conducting a detailed link-by-link inspection of the entire chain. This thorough approach is essential to ensure that all potential issues, such as wear, deformation, or damage, are identified. Each link of the chain can be a point of failure, and minor defects can lead to significant safety hazards during operation.

By inspecting each link, the inspector can assess the integrity of the chain more accurately, looking for signs of abrasion, cracking, elongation, or corrosion. Implementing such a meticulous inspection process helps in maintaining the reliability and safety of equipment that relies on the chain, which ultimately protects both personnel and assets in the operational environment.

Other methods, such as visual inspections from a distance or spot checks of a few links, do not provide the comprehensive assessment needed to ensure the entire chain's safety and functionality. Functional tests alone also fall short, as they do not adequately reveal hidden damages or wear that could compromise the chain's integrity over time.
