OSHA requires 2 guards ( top & bottom) on which of the following saws ?

• A. radial arm saw
• B. table saw
• C. portable circular saw
• D. hand fed ripsaw

Answer: (C)

The main idea is guarding against contact with a rotating blade. A portable circular saw exposes the blade at both the entry and exit points of a cut, so OSHA requires protection on both sides. The top guard covers the portion of the blade above the work as you push the saw through, and a bottom guard covers the portion of the blade that would be exposed below the work surface as the cut finishes. This dual protection is a characteristic safeguard for handheld circular saws because of how the blade sits and moves during cuts. Other saws use different guarding configurations that don’t rely on a separate bottom guard in the same way, so they aren’t described as requiring two guards.
