A fire at a two-story walk-up at 1445 Lusitana St. yesterday morning destroyed an upstairs apartment and shut down traffic on the west-bound Punchbowl on-ramp to H-1 Freeway.

The cause of the fire is under investigation.

No one was injured in the fire, reported at 7:50 a.m. and extinguished at 8:10 a.m., Honolulu Fire Department spokesman Capt. Terry Seelig said.

Seelig said seven adults and three children live in the upstairs, diamondhead apartment where the fire started.

Salome Pisaram, who lives in the apartment, said three adults and two children were in the apartment when the blaze started. A fourth adult, her sister-in-law, was returning home when the fire broke out and alerted everyone, Pisaram said.

"We lost everything, passports, birth certificates. ..." said Pisaram, who grabbed her 3-year-old son and ran from the apartment when her sister-in-law sounded the alarm.

The blaze caused about $130,000 in damage to the building and its contents, firefighters said.

Pisaram said she was in one of the apartment's two bedrooms at the time, and the fire began in the other bedroom.

Also in the apartment were her husband, her brother-in-law and 1-year-old nephew.

Pisaram said she has no idea where the family will go now.

Police diverted mauka-bound traffic on Punchbowl at Vineyard Boulevard.

Smoke from the fire was visible from H-1 Freeway as firefighters were responding to the blaze.

Honolulu police were also on the scene, trying to prevent residents from going back into the building.

Seelig said Pisaram's unit was destroyed. The building has three apartments upstairs, and a single unit and a garage downstairs, he said.

Five engine companies, two ladder trucks and a battalion chief responded to the fire.

A structure behind the apartment building sustained charring, Seelig said.

Maria Lutz of the American Red Cross Hawaii Chapter said the agency will be meeting with the family to ensure their immediate emergency needs such as shelter, clothing and food are met.
