Thank you everyone. Since this is a science lab I am going with OH2 to be safe.

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.

Quick question. 


College Lab classrooms.  Light or Ordinary hazard?
