The Mahoning County HAZMAT team is checking the air quality in the Valley after reports of an odor in the air due to the controlled release in East Palestine following the train derailment Friday evening. 

Valley residents in Boardman, Poland and Austintown have reported a strong odor in the air. According to the Mahoning County HAZMAT team, the shift in wind is what is contributing to the smell. 

According to Boardman Fire Chief Mark Pitzer, the Mahoning County HAZMAT team is in the area conducting an investigation as a precaution to calls that they've received throughout the evening.

On Facebook, Springfield Township Fire and Rescue is advising residents to shelter in place as a safety precaution. 

Their post reads in part: "we ask that you remain calm and remember this is only being done as a precaution to keep you, our residents safe. For more information please watch this page, and we ask that you only contact our non emergency dispatch line in reference to this if it is absolutely necessary as our dispatchers are working hard throughout the night." 

Springfield Local Schools also posted on their Facebook that the schools will be closed Tuesday due to an abundance of caution. 

The Mahoning County Emergency Management Agency also posted on their Facebook and advised residents to stay indoors. According to their post, this is not an order, but a recommendation. 

Their post reads: "We are currently working with resources deployed at the incident and are waiting on air quality test results. We will advise further at that time. Until more information is received, we urge everyone to use common sense and avoid outdoor activities."

Canfield Police also posted on Facebook recommending for residents to shelter in place, and the City of Struthers advised the same through their page as well. 

According to The Mahoning County Hazardous Materials Response Agency, team members are looking into the complaints, but are reporting that everything as of now is safe.
