What unit is this for? What have you recently been talking about in this class? I mean if you mean anyone, Tyler Joseph.
More information should be provided about the person quoted. (aPeX)
I believe the answer is: <span>60 (240)
According to fire codes </span>1910.106 (d)(3)(i) , <span>"Not more than 60 gallons of Category 1, 2 or 3 flammable liquids, nor more than 120 gallons of Category 4 flammable liquids may be stored in a storage cabinet."
These flammable liquids would include things such as diesel, motor oil, cooking oil, mercury, etc.</span>
