Greg, Depending on the amount of flammable/combustible liquids within a single control area as defined by the building code and the number of control area within the building the lab could possibly be considered an H Use Group by the Building Code. Control areas are areas separated from the remainder of the building by one hour rated construction.
NFPA 45 2004 Edition Chapter 6 "Fire Protection" defines the requirements for protection of the lab. Paragraph 6.2 defines the protection requirements for the lab depending upon the class of the LAB Class A and Class B labs are to be protected per NFPA 13 for ordinary hazard Group 2 occupancies while Class C and Class D labs are to protected per NFPA 13 for ordinary hazard Group 1 occupancies. The classification of Lab depends on the amount and type of liquids being stored. Hope this helps. Have a fire safe day!

Engineer specs OH II for the entire building including offices, etc. When I called he said he was open for discussion in case what he did was overkill. You are correct on the B Occupancy but it is sprinklered. Greg McGahan Operations Manager Living Water Fire Protection 1160 McKenzie Road P.O.

However depending on the chemicals used and specifically the quantities it could become and "H" occupancy. NFPA 13 would be appropriate in most cases but you cold be driven to NFPA 30 depending on quantities of materials. Someone needs to look at the quantities of materials used and stored within the building and do a Hazards/Code analysis. The only thing about mixing up design criteria for small spaces like restrooms is, are you really going to be able to get 0.10 for a few heads in a rest room when the adjacent areas could be 0.20 or 0.30?

If you have a lab in a stand alone building - regardless of class - all of the other rooms, etc should still be able to be protected per normal NFPA 13 requirements, correct? Bathrooms would be Light Hazard and so forth? We have an engineer that is not sure. And I am just making sure I am correct and that a lab is no different than any other mixed occupancy classification like retail, etc..
