Helmets used in high-angle work should have a three-point suspension system. This design is important because it enhances the stability and security of the helmet when it is worn, ensuring that it remains securely in place during dynamic movements or unexpected impacts. A three-point suspension system achieves this by employing a combination of a headband and straps that attach at three points: above and behind the head and around the chin or neck area.

This configuration helps in distributing the weight of the helmet evenly while allowing for a more secure fit, which is crucial in high-angle environments where falls or traumatic impacts may occur. It reduces the risk of the helmet slipping off during rescue operations or when engaging in activities at heights, thereby providing adequate protection.

In contrast, other types of suspension systems do not provide the same level of security and fit. For example, a two-point suspension system might not offer adequate stability, while a compression system or buckle closure alone lacks the comprehensive retention that a three-point system provides. As such, the three-point suspension system is specifically designed to enhance safety and performance in high-angle rescue operations.
