The Honolulu Fire Department says an unknown chemical substance that was discovered inside a Chinatown apartment complex was not hazardous.
Firefighters got the call just after 9:00 p.m. Saturday night at the Maunakea Tower. A report of a white powdery substance was discovered in the hallway of the 23rd floor.
Three residents were taken to the hospital complaining of irritation to the eyes and throat.
Tests determined the substance was possibly material found inside a fire extinguisher.
