Which PPE has an expiration date?

The correct answer is that respirators have an expiration date. This is because respirators, especially those that contain filtering mechanisms, are designed to provide a specific level of protection against airborne contaminants. Over time, the materials and filters in a respirator can degrade due to exposure to wear, moisture, and environmental factors, which can significantly reduce their effectiveness.

Manufacturers often specify an expiration date for these devices based on testing and standards to ensure users are protected adequately while using them. This is critical in environments where air quality may be compromised.

While safety glasses, hard hats, and hearing protection do have certain wear and tear considerations, they typically do not come with an explicit expiration date in the same way respirators do, although they should be inspected regularly for any signs of damage or degradation.
