Boiler emergency kill switches

Standard Building Code

Is anyone familiar with a requirement to have an emergency boiler kill switch at boiler room exits? I refer to a "mushroom" type big button that will kill all boilers in the room when pressed.

Specifically down south in the Standard Building Code/Standard Mechanical Code jurisdictions.

If so, can you point me to where the requirement might be found?

Thanks.

Could it be ...

that you are refering to CSD-1?

It does require a "kill" switch (not necessarily a push button mushroom type) outside the boiler room door.

CSD-1 applies to larger boilers (>400 MBH) and has been adopted in several southern states.

Does this help?

I don't recognize that acronym - CSD. Can you help?

CSD-1

ANSI/ASME -- Controls and Safety Devices for Automatically Fired Boilers. A national code, that has been adopted by many states. Applies to larger boilers >400,000 Bth (does not apply to residential).

More CSD-1 info ...

Here is a website:

& I will attempt to attach a spreadsheet that lists all the states that have adopted CSD-1.
