Emergency Boiler Shutdown
Are heat detectors or Fire Alarm and Detection System (FADS) required to be tied-in for emergency boiler shutdown? Or, what are the requirements for emergency boiler shutdown for large industrial boilers?
I believe you need to take a look at NFPA 85. It spells out the requirements for boiler and combustion safety shutdown systems.
We have just installed two new boilers and were required to install emergency shut downs outside of the room at each entrance for emergency personnel.
This is code in minnesota
Minnesota Rules, Chapter 4715.
