Which of the following is NOT an acceptable method for inspecting a hard hat suspension?

Wearing a hard hat during a test is not an acceptable method for inspecting its suspension because it does not provide an objective evaluation of the hard hat's condition. Instead, inspections should focus on assessing the integrity of the suspension system without the influence of external factors that come from wearing the hard hat. Effective inspection methods must ensure that the suspension is functioning properly to provide adequate protection.

In a hands-on environment, the other methods mentioned are reliable. Visual inspections allow for the detection of any visible wear or damage, flexing tests can evaluate the stiffness of the suspension components, and checking for loose straps is crucial to ensure that the hard hat fits securely and functions effectively. Each of these practices contributes to maintaining safety standards, while simply wearing the hat does not facilitate a thorough examination of its condition.
