Explosion Proof in Paint Storage Room

Facilities personnel at one of our sites is inquiring about the need for an explosion proof thermostat in a paint storage room (storage only in paint cans, room is fire-rated).  From my search it does not seem to be required.

 

NFPA 1:66.7.3.3 table, intimates that the area is classified as a Class I, Div 2, Zone 2.  NFPA 70:501.10(4) states that "boxes and fittings shall not be required to be explosion proof". I do not deal too much with the NEC.  Am I interpreting these correctly?

 

Any direction would be appreciated.

 

Thank you.
