Vale says there is no risk to the community and has given "all clear"

Updated August 13, 2015 9:15a Vale says in their statement this morning that there was a release of nitrogen oxide and nitrogen dioxide (NOx) mist during planned maintenance resulting in a Level 3 Emergency at approximately 6:00am

Statement From Vale:

During the planned maintenance period of the Vale Acid Plant in Copper Cliff, there was a release of nitrogen oxide and nitrogen dioxide (NOx) mist. Emergency measures were activated and as a precaution a Level 3 emergency was called. The emergency air horn was sounded at approximately 6:00 a.m.to notify residents in the nearby area.

Emergency and Vale personnel are now satisfied that the NOx mist has dissipated giv...en the wind speed and weather conditions and there is no risk of additional substance traveling beyond company boundaries. Therefore, there is no risk to the community. The Level 3 emergency has therefore been declared ‘all clear’ at 8:26 a.m.

If a person is exposed to a NOx, symptoms can include nose, throat, eye, skin and respiratory irritation. If these symptoms should occur, a person should find fresh air and flush any irritated area with water. If symptoms persist, a person should seek medical attention.

The incident closed area roads including; Big Nickel Mine Road closed in both directions, Regional Road 55 closed in both directions, Lasalle Extension closed at Frood Road, and Lasalle Extension closed at Big Nickel Mine Road until approximately 8:30am
