What aspect of the hard hat should be examined for dents during an inspection?

The shell of a hard hat is the primary component that protects the wearer from impact and penetration. Inspecting the shell for dents is crucial because any deformation can compromise its ability to absorb shocks. Dents may indicate that the hard hat has previously withstood a significant impact, potentially weakening its structural integrity.

While the brim, insulation, and lining are also important aspects of a hard hat, they serve different functions. The brim helps with sunshade and provides lateral protection, insulation is meant for temperature regulation, and the lining contributes to comfort and fit. However, it is the shell that is most critical for ensuring the hard hat remains effective in protecting against head injuries, making it essential to examine this area during inspections.
