Additionally, N=46PA limits the amounts of hazardous materials in a control area with Maximum Allowable Quantities dependent on fire suppression systems, leak detection, ventilation,  and so forth. A =46ire Protection Engineer in your jurisdiction would be able to detail the code requirements for your control area.

A control area is an area that is fire separated from adjacent areas. A laboratory is typically a control area. The higher up you are in a building the less control areas are allowed. I will sent the exact definition once I get to my office

Hello Everyone,

I am reaching out as I need to know the practical definition of a =22control area=22.  The N=46PA definition is vague and has been interpreted by someone as the whole floor of our building.  I find this hard to believe when it is often being used as =22laboratory suite or control area=22 in the standards.  Any help would be greatly appreciated.

Thank you,
