Several streets in southeast Edmonton were shut down to all traffic, early this morning, as emergency crews tackled a potentially-dangerous chemical reaction.

A lime pit, near 82 Avenue and 43 Street, mixed with water from the high humidity and caused a hazy plume to develop in the industrial area.

Holly Budd, with Edmonton Fire Rescue, says they're dumping loads of dry sand on the site to try and smother the reaction. She adds that it could take days to completely go out.

Budd says the incident is considered 'under control' and there is no threat to any homes or occupied areas.

There are no reports of injuries.
