b. Field inspections. After the drawings are obtained or prepared, conduct a comprehensive survey of the grounding, bonding, shielding, and lightning protection practices throughout the facility. This survey should cover all the major elements of the fault protection subsystem, signal reference subsystem, bonding (both in current paths and between structural elements), lightning protection for the structure, and shielding for both electromagnetic interference (EMI) [and electromagnetic pulse (EMP), if required] and personnel protection. (1) Visual observations should be concisely documented and related to the engineering drawings for the facility. Measurements performed and data collected should be accurately documented on the survey form. The steps of the inspections are as follows. (a) Analyze the earth electrode subsystem and measure its resistance to earth (figure 6-1). (b) Inspect a representative number (5 to 10 percent) of the bonds throughout the facility
