WILLIAMSTOWN, Mass. — About two dozen people were evaluated for minor respiratory irritation Sunday afternoon during a tag sale at First Congregational Church.

 

Fire Chief Jeffrey Dias said the department was called at about 2 p.m. after a number of people participating in the sale reported minor breathing issues.

 

Emergency medical services personnel examined 28 people, but none were transported from the site by ambulance, Dias said.

 

He asked for a Tier 1 hazardous materials response from the Massachusetts Department of Fire Services, which arrived on scene just before 4 p.m.

 

At about 4:15, Dias said he expected the room where the tag sale was held shortly to be given the all clear for reoccupation.

 

Dias said the source of the respiratory irritation had not been determined and was still under investigation.
