A 63-year-old man was transported to Wahiawa General Hospital for treatment of smoke inhalation. He was later moved to Kuakini Medical Center for treatment in a hyperbaric decompression chamber, according to the Honolulu Emergency Services Department.

A 53-year-old man was transported to Wahiawa hospital in stable condition for treatment of minor injuries.

Fire Battalion chief Ron Rico said five adults and one teen were in the four apartments.

Seven units from the Honolulu Fire Department responded to the call just after 2:30 a.m. and had it under control by 2:47 a.m.

Joey Blacksher, a resident who fled his burning apartment with his wife Kendle, said, "We heard a lot of yelling and screaming and we thought it was a fight outside."

Blacksher, an Army infantryman, added,"We looked out the window and saw the fire. It was right against our living room wall, and all my military gear was against the wall."

Fire investigators this morning were looking into the cause of the fire and assessing the damage caused.

Blacksher, who had to run down steps that were on fire, said the blaze may have been tied to an electrical problem. The Blackshers, along with neighbors, said they heard loud popping noises and pointed out that fuse boxes are housed in the area where the fire appears to have started.

"We had friends bring us some clothes and my wife was smart enough to grab a towel as she ran out," Blacksher said.
