Step-by-step explanation:
The condition of a helmet can be determined by checking for any visible damage such as cracks, dents, or discoloration. The straps and buckles should also be inspected to ensure they are in good working condition. Additionally, the helmet should be checked for any signs of wear and tear, such as frayed padding or loose fittings.
Reconditioning and recertification of helmets involve cleaning, repairing or replacing damaged parts, and testing the helmet to ensure it meets safety standards. This process helps extend the lifespan of the helmet and ensures its continued effectiveness in protecting the wearer.
