How can team members check if a harness is properly fitted?

The correct answer emphasizes the importance of a thorough and standardized method for ensuring that a harness is fitted correctly. Completing a two-finger check at each point is a widely recognized technique in safety practices. This method involves inserting two fingers between the harness straps and the body to ensure that it is snug but not overly tight. This check helps to confirm that the harness will function effectively in case of a fall, providing the necessary support and security without causing discomfort or restricting movement.

Relying solely on visual inspection may not provide sufficient assurance that the harness fits correctly. While pulling on the harness can give some indication of its secure fit, it doesn't assess how the harness interacts with the body or whether it allows for proper movement. Asking the jumper might yield subjective responses that do not guarantee the harness's effectiveness, particularly if the jumper is not well-versed in safety standards. Thus, the two-finger check serves as an objective and reliable method to ensure proper harness fitting, thereby enhancing safety for team members.
