Final answer:
Replace damaged head protection immediately to ensure the highest level of safety and prevent potential head injuries.
Step-by-step explanation:
When inspecting head protection such as safety helmets, if you find evidence of damage, including dents, cracks, or penetration, the appropriate course of action is to replace the head protection immediately. Continuing to use damaged head protection or attempting to repair it can compromise the level of protection it offers, potentially leading to serious injury. Protective equipment like safety helmets are essential in preventing head injuries during activities and occupations where there is a risk of objects falling or colliding with the head.
