Chinstraps for safety helmets vary depending on their intended usage. Selecting a helmet with the right type of chinstrap is key to ensuring that the wearer is properly protected against hazards on site.
There are important distinctions between the requirements set out in three of the main European helmet standards. EN 397 and EN 14052 chinstraps operate in the same way, whereas EN 12492 chinstraps work differently.
EN 397 and EN 14052 chinstraps
A common misconception is that all safety helmets must be supplied with a chinstrap. While EN 12492 helmets must incorporate a mandatory chinstrap, this does not apply to EN 397 industrial safety helmets or EN 14052 high performance helmets.Both EN 397 and EN 14052 helmets must be designed with the means to attach a chinstrap, but do not always need one.
Chinstraps are optional for these helmets because, during general use, the helmet is secured on the head by the internal harness and ratchet system. A chinstrap can be useful for certain applications, such as tasks involving vigorous movement or in spaces with obstacles that may dislodge the helmet.
Optional chinstraps for EN 397 and EN 14052 helmets must release under a force of 150-250N if caught up creating danger for the user. This reduces the risk of injury in case the strap becomes snagged on machinery in an industrial environment.
EN 12492 chinstraps
Chinstraps are mandatory for EN 12492 helmets, forming an integral part of the retention system. All helmets meeting this standard are supplied with a chinstrap fitted.
The retention system is tested to ensure the strap does not break or stretch when a force of 500N is applied. EN 12492 also includes test requirements to make sure the helmet cannot roll off the head if caught at the front or the rear. This maximises protection during a fall, helping to keep the helmet secure in case of repeated impacts from swinging or multiple falling objects.
EN 12492 chinstraps are pre-fitted and cannot be replaced by the user. Due to the way the retention system operates, if an EN 12492 chinstrap is broken or damaged the helmet must be replaced.
Selection
To select a chinstrap, consider the task and environment. Think about the work being carried out and what hazards are present.
EN 397 and EN 14052 helmets can generally be worn without a chinstrap. When working in areas with low ceilings or overhead obstacles, as well as for tasks requiring vigorous movement, a chinstrap can be fitted for increased security.
In environments where helmets could become snagged on machinery or other equipment, EN 397 or EN 14052 chinstraps offer a safe option. However, where there is a risk of swinging or multiple falling objects, an EN 12492 helmet can be required to protect against repeated impacts.
There are other important differences between these safety helmets, including impact protection and electrical performance. A full hazard and risk assessment must be completed to determine the appropriate type of helmet and ensure the chinstrap is suitable for the application.
