A fixed-position face shield may be used any time eye protection is necessary.

A fixed-position face shield is not always appropriate for all situations requiring eye protection. While it offers a level of protection to the eyes and face, it is not suitable for every circumstance, particularly when there is a risk of high-pressure impacts, chemical splashes, or where special optical protection is required.

For instance, in laboratories or environments where there is a risk of chemicals or biological material splashes, a face shield should be used in conjunction with safety goggles or glasses that provide a snug fit around the eyes to ensure comprehensive protection.

Moreover, certain activities may require specific types of eye protection, such as safety glasses with impact resistance or specialized eyewear for specific risks not adequately mitigated by a fixed-position face shield. Thus, the assertion that a fixed-position face shield may be used anytime eye protection is necessary is incorrect, as it does not account for the variability of hazards present in different environments and tasks.
