Air quality is consistently being monitored during cleanup operations at the scene of a chemical plant fire in Mount Vernon.

A week and a half ago, a fire raged at the KEM chemical warehouse on South Fulton Avenue. Since then, there has been mounting concern over what could have been in the smoke and what effect it could have on the air quality in the area.

City fire officials say they have found no dangerous chemicals in the air. They say there are two agencies monitoring the air day and night and there has been no cause for alarm.

The street is still blocked off during the demolition of the building. Fire officials do not know how the fire started or if the chemicals being stored in the warehouse were the cause.

The Westchester County Health Department has also been on the scene running its own air quality tests. However, the testing is nowhere near complete. It will take a while to completely demolish the building and air quality teams are continuing to run tests every time a section is ripped down.Firere-ignites at Mount Vernon chemical plantMt.Vernon cautious over chemical plant demolition
