An 83-year-old man is in critical condition after evacuating his unit at Rainbow Place as Honolulu firefighters extinguished a blaze on the 21st floor Saturday morning.

Firefighters responded to a three-alarm fire at the high-rise on 2754 Kuilei St. in Moʻiliʻili, according to HFD Capt. Scot Seguirant.

The first unit arrived at 10:07 a.m. to find black smoke and flames coming out of a window.

The fire was brought under control around 10:40 a.m. and extinguished at 10:58 a.m.

EMS officials said that the elderly man was waiting across the street in a safe area, where he reportedly collapsed.

The man did not come in contact with smoke or flames while he was in the building, according to EMS officials. 

Paramedics on scene administered CPR. The man was transported to an area hospital in critical condition. 

"Watching that at a close distance is just emotional," University of Hawaiʻi Mānoa student Amlan Fujimura said of the man's condition.

Fujimura lives in a nearby complex and saw paramedics administering CPR on the man.

The cause of the fire was ruled as accidental by an unspecified arc in a lighted display case. Damage costs are estimated at $484,000.

The building did have a working smoke alarm, but no fire sprinklers.

The occupant of the blazed unit was not home at the time of the fire.

Rainbow Place is located in close proximity to UH Mānoa and Puck's Alley.

Kuilei Street was closed during the incident.
