Which type of guards can be moved or hinged?

Barrier guards are specifically designed to provide protection while allowing for movement or access when necessary. These guards can be hinged or movable, enabling them to be opened or repositioned for maintenance, operation, or inspection while still serving as a protective measure. This flexibility is essential in many industrial settings where access to machinery is required but safety must still be prioritized.

The other choices refer to components or devices that have different functionalities. Lockout devices are used to isolate energy sources and ensure that machines cannot be operated unintentionally during maintenance. Nip points are locations where body parts could be caught between moving machine parts, which are a hazard that barrier guards help to prevent. Machine covers are fixed enclosures that protect employees from moving parts but do not typically hinge or move, making them distinct from the category of barrier guards.
