Relief System and Flare Header Design

Pressure relief and effluent handling systems are the last lines of defense against equipment overpressure and the subsequent consequences of loss of containment. Relief system design and design basis are specifically defined as process safety information in OSHA’s 1910.119 Process Safety Management mandate of 1992. Recent OSHA National Emphasis Program (NEP) audits have consistently identified deficiencies in the relief systems across the U.S.
