What topics are typically covered by NFPA 85 for boilers?

• A. Electrical wiring safety
• B. Safe operation of boilers and process heaters, including flame safeguards, start-up/shut-down procedures, ventilation, and maintenance
• C. Building egress
• D. Fire extinguisher placement

Answer: (B)

NFPA 85 centers on the safe operation of boilers and fired process heaters. It outlines how burner controls and flame safeguard systems should function, including interlocks that detect flame presence and shut down fuel if the flame is lost. It also covers start-up and shut-down procedures to avoid dangerous transients, as well as ventilation requirements to ensure proper combustion air and safe removal of combustion byproducts. A maintenance program is part of the standard too, ensuring safety devices, controls, and ventilation remain reliable over time. This combination of topics is specific to boiler and process heater safety and operation; topics like general electrical wiring safety (addressed by electrical codes), building egress (life-safety codes), or fire extinguisher placement (standards for extinguishers) fall outside its scope.
