What component should you adjust to ensure your hard hat fits properly?

To ensure your hard hat fits properly, you need to adjust the suspension system. The suspension system is the internal framework that holds the hard hat away from your head and helps to absorb impacts. A properly adjusted suspension system can help distribute the weight of the hard hat evenly, provide comfort, and maintain a secure fit. This is crucial for safety, as an ill-fitting hard hat could shift or fall off, compromising protection in hazardous environments.

While the chin strap contributes to keeping the hard hat in place, it does not fundamentally adjust the fit of the hard hat around the head. Similarly, the visor is primarily designed for eye protection and does not affect the overall fit of the headgear. The brim size, while part of the hard hat's design, is typically fixed and does not provide a method for adjusting the fit on an individual basis. Therefore, focusing on adjusting the suspension system is key to ensuring optimal fit and safety.
