Six families are without a home Saturday night after a three-alarm building fire in Moiliili.
The building doesn't have fire sprinklers and that helped the flames spread quickly, according to the Honolulu Fire Department. 

Georja Skinner lives across from where the blaze started. She’s been living in the Rainbow Place Condominiums for almost eight years. She says there were fire alarms in the past but this is the first time danger got so close to her front door. 

"I think the main thing is it's just a frightening feeling for anyone. Being on the 21st floor directly from a fire, all you can do is pray and hope that the firemen get here quickly which they did. They put out the fire well, it took some time," Skinner said. 

HFD said the man who lives in the unit was not home when the fire started. It also reports a neighbor on the top floor initially smelled smoke, pulled the fire alarm and called 911. 

Residents evacuated at the Prince Jonah Kuhio Elementary School, some nervously watched the firefighters work.

"We don't have a sprinkler system, I knew. It's on the top floor, no sprinkler system, this one is gonna be kinda tough to put out. It took a little while before we saw the water hoses get up there," Rachel Arroyo, another resident, said. 

HFD continues to emphasize sprinklers are the most effective way to battle a fire safely and quickly. The building did have a working smoke system. 

"With the fire sprinkler system, that initially gets water on the fire to control it and that's what we're trying to do. Get a water supply, get water then bring the fire under control then we can actually extinguish it to minimize the extent of damage and effects it has on other occupants," Alan Carvalho, HFD battalion chief, said. 

An 83 year old man went into cardiac arrest after leaving the building. Honolulu emergency medical services took him to the hospital after performing CPR. 
HFD says the cause of the fire and damage estimates are still under investigation.
