What is a practical way for workers to test the fit of a safety helmet?

A practical way for workers to test the fit of a safety helmet is by shaking their head. This method allows the wearer to immediately assess whether the helmet stays securely in place. A properly fitted helmet should not shift significantly when the head is moved, indicating that it is snug and appropriate for the wearer's head size and shape.

While checking the size label and lifting the helmet slightly might provide some assistance in ensuring a good fit, these methods do not give a direct indication of how well the helmet will stay on during movement, which is crucial in the event of an incident. Estimating head shape can be subjective and may not provide an accurate fit assessment. The shaking method is practical because it mimics real-world conditions where the helmet must remain secure during various activities.
