Final answer:
In the context of machine guarding, 29 CFR 1910.211 defines a 'bite' as the point where two machine parts contact, which is associated with the potential risk of injury in a workplace.
Step-by-step explanation:
According to 29 CFR 1910.211, the term 'bite' in the context of machine guarding refers to Option 2: The point where two machine parts contact. This is particularly pertinent in the areas of a machine where work is actually performed, such as the point of operation, and it is a key term for understanding how to assess potential hazards when operating or working near machinery. The primary concern with the 'bite' is the risk of injury that can occur if a part of the body or a piece of clothing gets caught between the moving parts of a machine.
Machine guarding is essential because it provides a critical means of reducing the risk of accidents and injuries. Appropriate guarding can prevent contact with the 'bite' and other dangerous parts of a machine, thereby significantly reducing the likelihood of workplace injuries.
