Truth: Not if your plant has any digital communication (Modbus, OPC, etc.) between the BMS and DCS. The 2019 edition added crucial requirements for cyber-secure communication between safety and control networks.
These are the "safety nets" designed to prevent catastrophic failure. They include alarms and Safety Instrumented Systems (SIS) that trigger automatic shutdowns if critical limits are exceeded. A key safety requirement is preventing the accumulation of combustibles in the firebox; for instance, action must be taken before concentrations exceed 25% of the Lower Explosive Limit (LEL). API RP 556 (R2024) Most Recent - Accuris Standards Store
Based on refinery audit findings, here are frequent failures even when someone has an on hand:
Ensuring safe sequences during startup, operation, and shutdown. Measurement Reliability:
In line with IEC 61511 and ISA-84, RP 556 defines Safety Integrity Levels (SIL) for heater and boiler functions. Typical SIFs include:
