Basically, a "garage" is where vehicles are stored, which also means gasoline (or other flammable fuels) are also stored there (unless, I guess, if you were to drain the fuel tanks and oil out each time before moving the vehicle into the "garage".
A "shop" would be (in my opinion) a "workshop" where work is done, things are worked on, built, deconstructed, etc., and could include the incidental vehicle or parts thereof (i.e., the vehicle is not stored there, and, in all likelihood, the vehicle or parts would not be fully assembled and would not be operational, thus no stored fuel.
Using an open flame heat source in an area where flammable fuels are stored is ... well ... one should not even need a code to say this ... it is *DUMB*. Would be high on the Darwin Award Candidacy list.
