This recommendation from the CSB will likely lead to a future revision of API RP 556, potentially changing many recommendations from "should" to mandatory "shall" requirements.
API RP 556 is built around three major functional areas that work in tandem to ensure heater reliability: api rp 556 pdf

Utilizing legitimate copies ensures access to the most recent errata, addenda, and technical revisions.
API RP 556 remains a cornerstone document for maintaining safety and efficiency in high-temperature process environments. By strictly adhering to its recommendations for burner management, cross-limited combustion control, and comprehensive process monitoring, facilities can dramatically reduce the likelihood of combustion incidents while optimizing their energy usage and environmental footprint.
Effective control systems manage the heater's temperature, pressure, and fuel-air ratio. The standard provides best practices for these systems to keep the heater within its safe operating envelope, thereby reducing the likelihood of process upsets. tied directly to heater operations
