Which statement about pneumatic chipping tools is TRUE?

Correct Answer: Option D — The equipment shall be secured to the hose by a quick-disconnect coupling to prevent the tool from becoming accidentally disconnected.

Pneumatic tools are subject to high pressure, and hose failure or disconnection can cause the tool to whip violently. Using a safety-rated quick-disconnect coupling or a whip-check cable is a mandatory safety requirement to ensure the tool remains securely attached to the air supply hose during operation.
