Check out NFPA 45 Table 9.1.1(b). This will give you a fire hazard class based on quantities of flammable and combustible liquids. Then if you look in chapter 6 (6.1.1.1) it will tell you whether it is OH1 or OH2.
I know the MN Fire Code for instance says “Chemistry Labs” are OH2 but it makes sense to me that it would depend on the type and quantities of combustible liquids. Reed A.
