What distinguishes a fixed guard from other machine guards?

A fixed guard is designed to provide a permanent barrier between the operator and the moving parts of a machine, ensuring safety during operation. The key characteristic that distinguishes it from other types of guards is that it requires tools for removal. This feature ensures that the guard remains in place during typical operations, providing continuous protection and reducing the risk of accidental removal that could lead to safety hazards.

In contrast, other types of guards, such as adjustable guards, may allow for easier access or may be removed without tools, which can compromise safety if not monitored properly. Types like removable or adjustable guards typically cater to specific tasks or setups but may not provide the same level of consistent safety as fixed guards, which are meant to stay in place and function as a reliable safety measure.
