Honolulu firefighters responded to two separate fires in Aiea and Waikiki Sunday night.

At about 9:13 p.m., 30 firefighters responded to a two-alarm fire at Taco Bell at Pearlridge Center Phase 1 where they observed smoke emerging from the fast food restaurant’s exhaust vent.

A contractor hired to clean the cooking exhaust vents told firefighters a fire occurred while cutting an access hole to clean the vent system and that they immediately extinguished it, according to a news release from the Honolulu Fire Department.

There were no injuries.

Firefighters remained at the scene to check whether the fire was fully extinguished.

Approximately 20 minutes later, 18 firefighters responded to a fire at the Ambassador Hotel fire at 2040 Kuhio Ave. Upon arrival, they saw smoke coming from electrical conduits between the 15th and 16th floors.

Firefighters checked the building for any fires, according to the fire department.

No injuries were reported and firefighters administered ventilation operations to clear the building of smoke.
