Three workers were injured, one seriously, in an explosion at a Clearwater dealership this morning.

It happened at the Lokey Mercedes Benz dealership at 19820 U.S. 19 N. around 10:30 a.m.

A 47-year-old man was taken to Bayfront Health St. Petersburg for treatment of injuries that were serious but not thought to be life-threatening.

Two others who were near the scene of the explosion declined medical treatment.

A subcontractor was at the site Tuesday morning attempting to perform repairs to a hydraulic lift when the explosion occurred in the service bay.
