E&S Grounding Solutions provides comprehensive, instrumented NFPA 77 Static Electricity Site Audits for industrial facilities handling flammable liquids, gases, vapors, and combustible dusts.
Our licensed engineers conduct five-phase audits: Design Review and Hazard Assessment, On-Site Visual Survey, Instrumented Resistance Testing, Earth Electrode Verification, and Flow and Relaxation Analysis.
Every audit is performed with intrinsically safe, NIST-traceable calibrated instruments certified for Class I and Class II hazardous locations, including milliohm meters, megohmmeters, non-contact electrostatic field meters, and 3-point fall-of-potential ground testers.
NFPA 77 §7.4.1.3.1 establishes that all-metal continuous ground paths must measure less than 10 ohms. Our audit verifies every critical grounding path against this and all other applicable NFPA 77 resistance thresholds.
Industries served include petrochemical and refining operations, bulk liquid terminals, pharmaceutical manufacturing, powder and bulk solids handling, aviation and aerospace, and defense and government facilities.
Every audit concludes with a comprehensive engineering report including system sketches, resistance measurement logs, hazard identification by process area, a discrepancy tracking log, a corrective action priority list, and instrument certification records.
