Guam - After closing for the past two days, the Department of Revenue & Taxation reopened for business this morning. It was on Tuesday when DRT's uninterruptible power supply machine in the Computer Systems Room caught fire filling the entire facility with heavy smoke. As a result, a lingering foul odor remained in the facility causing several employees to leave after falling ill.

Deputy director Marie Benito tells KUAM that staff opened up the building all through the night and  deodorized the smell. She adds the Guam Fire Department already tested for air quality and did not find any unsafe chemicals in the air.

As a result of the two day closure, the agency will expand hours of operation next week from 7am to 6pm from September 3 to September 6.
