70% to pass

When using a pneumatic chipping tool all of the following are TRUE except?

A The equipment is not required to be grounded to prevent shock hazard.
B The equipment shall be secured to the hose by a quick-disconnect coupling to prevent the tool from becoming accidentally disconnected.
C It is not intended to be used in an explosive atmosphere.
D The needles of the needle-type chipping gun must be replaced when they have been blunted more than ½ of their diameter.
AI Explanation

The correct answer is A) The equipment is not required to be grounded to prevent shock hazard. The reasoning is that pneumatic chipping tools, being powered by compressed air rather than electricity, do not pose a shock hazard and therefore do not require grounding. The other answer choices are true requirements for the safe use of pneumatic chipping tools. B, C, and D are all correct statements about the proper use and handling of pneumatic chipping tools to ensure safety. However, the requirement for grounding to prevent shock hazard is not applicable for this type of equipment.
