All floors were evacuated except the ICU and CCU units and the ER, meaning 128 patients were evacuated in total. The evacuation took a total of 20 minutes.

Outpatient surgeries were canceled for Friday, but will be up and running again on Saturday.

Hospital officials said they ran a training with the fire department on May 2, and attributed this training as what made today's evacuation go so smoothly.

Investigators determined a roofing company had been working at the building and finished work around midnight. Part of the roofing process used torches to apply hot asphalt roofing material.

Combustibles on the roof were seemingly ignited by embers left over from the process, resulting in the fire. Minimal damage was done to the building.
