The document provides guidelines for properly fitting and removing helmets. It states that a helmet should fit snugly without relying on the chin strap, and lists dangers of improper fitting such as concussions or facial injuries. It notes helmets should only be removed if the airway is accessible or the facemask cannot be removed, as spinal injuries could be inflicted or the airway lost. Techniques for removal include immobilizing the head, cutting facemask fasteners, and sliding off the helmet by removing ear pads.
