When attending to an injured motorcyclist, it is important **not to remove their helmet**. This is because the helmet is a piece of **passive safety** equipment that protects the head from serious injuries. Removing it could **worsen potential injuries** to the head or neck of the injured person.

- The helmet distributes the force of an impact across its entire surface, preventing it from concentrating in a single point and thus reducing the risk of severe injuries.
- Additionally, it protects the head from impacts against the ground, other vehicles, or road elements, and prevents sharp objects from penetrating the head.
- In the event of an accident, the helmet also helps prevent burns to the face and head when sliding on the ground.

For these reasons, it is crucial to keep the helmet in place until emergency services arrive, as they are trained to handle the situation without causing additional harm.
