Specifications for monitoring fuel gas header pressure and draft pressure within the radiant and convection sections.

, titled "Instrumentation, Control, and Protective Systems for Gas Fired Heaters," provides the definitive framework for managing these risks through standardized design and operational practices. Scope and Application

: Moving to an "API Standard" allows for stricter engineering safeguards. Organizations like the U.S. Chemical Safety Board (CSB) have recommended using "shall" language to mandate instrumentation that detects afterburning and prevents tube ruptures.
