Question

which of the following is a pinch point? (check all that apply)

a a roller on a conveyor belt
b rungs of an extension ladder
c the drawer of a filing cabinet
d a hammer handle
e a blade on a grader

Explanation:

Define pinch point hazards

A pinch point is any point where it is possible for a part of the body to be caught between moving parts, or between moving and stationary parts of a machine or piece of equipment.

Evaluate each option

• A roller on a conveyor belt: The rotating roller and the moving belt create a classic in-running nip point (pinch point) where fingers or clothing can be drawn in.
• Rungs of an extension ladder: When an extension ladder is being extended or retracted, the sliding sections create a pinch point between the overlapping rungs.
• The drawer of a filing cabinet: Closing a drawer creates a pinch point between the moving drawer front and the stationary cabinet frame.
• A hammer handle: A standard hammer handle does not have moving parts relative to another surface that would trap or pinch body parts during normal use.
• A blade on a grader: A grader blade is a cutting/shearing hazard rather than a pinch point hazard.

Answer:

• (A) A roller on a conveyor belt (Correct answer)
• (B) Rungs of an extension ladder (Correct answer)
• (C) The drawer of a filing cabinet (Correct answer)
• (D) A hammer handle
