3. Fixed guards:
Fixed guards are permanently attached to the machine or tool, don’t have any moving parts, and can’t be moved while the machine is in use. They’re most often used to enclose the point of operation, or other hazards that the operator doesn’t need to interact with, like fan blades or flywheels.

6. Damaged guards:
You should always report missing, damaged or inoperative guards. It is not safe to operate machinery without properly working guards. If a guard is damaged or becomes inoperative while you are working, shut the machine down, and have the guard inspected by a qualified person. The guard may need to be repaired or replaced before work can safely proceed. If unexpected machine start-up could cause injury, use the lockout/tagout program.

These are particularly useful in situations where operators need to be able to open the guard or access the guarded parts of the machine, such as when clearing jams. These guards allow safe access to interior parts of the machine without requiring a total disassembly.
