Which of the following is not considered a major type of machine guard within general industry?

The classification of machine guards is important in workplace safety standards, particularly in general industry. Among the major types of machine guards, fixed guards, interlocked guards, and adjustable guards are recognized for their specific protective functions and applications.

A fixed guard is a permanent part of the machine, designed to prevent access to hazardous areas during operation. An interlocked guard is a type that can disable the machine when the guard is opened or removed, ensuring that operators cannot access dangerous areas while the machine is active. Adjustable guards offer flexibility, allowing adjustments to accommodate different sizes of materials or operations while maintaining protection from hazards.

Swing-away guards, while still a guard type, are often considered less frequently mentioned in the context of major machine guarding classifications. They are designed to swing out of the way, providing access to the machinery for maintenance or adjustments, but they do not provide the same level of continuous protection as the other three types. Thus, when discussing the "major types" of guards, swing-away guards are not typically categorized alongside fixed, adjustable, and interlocked guards. This distinction clarifies why swing-away guards are not considered a major type within general industry safety protocols.
