TCFP Plans Examiner Practice Test

In accordance with NFPA, all aspects of quenching operations must be electronically grounded according to which Recommended Practice?

1. 60

2. 70

3. 77

4. 80

The correct answer is: 77

The correct choice is C, as NFPA 77 specifically addresses the grounding of equipment to control static electricity, which is crucial in quenching operations. This Recommended Practice provides guidelines for the grounding and bonding of conductive materials to minimize the risk of static discharge, which can be responsible for fires or explosions in environments where flammable substances are present. This emphasis on grounding is vital in operations that involve liquids or powders that could accumulate static charges. The procedures outlined in NFPA 77 ensure that all conductive aspects of the quenching operation are properly grounded, protecting both personnel and equipment. By adhering to these standards, safety is enhanced in potentially hazardous situations. The other options refer to different practices: NFPA 60 relates to the storage and handling of combustible metals, NFPA 70 pertains to electrical safety in workplaces, and NFPA 80 focuses on fire doors and windows. While all these topics are important in their contexts, they do not specifically address the fundamental grounding requirements necessary for managing static electricity during quenching operations.
