I work in building maintenance, and my company has numerous barns and large garages for vehicle parking, and tool storage. Would these fall under NEC 210.8 (B) 8 requiring every 120V receptacle to be GFCI protected?
Yes, those spaces require GFCI protection. That code also requires GFCI protection for any 240V receptacle rated up to 50A. The protection can be provided by a listed GFCI circuit breaker.
