NORTH KINGSTOWN, R.I. — A Rhode Island Walmart has reopened after 15 people were evaluated and one hospitalized from an unknown air irritant.
The North Kingstown Fire Department responded to the store around 1:45 p.m. after several employees and customers reported bouts of coughing.
Fire officials evacuated the building, and one person was transported to the hospital for difficulties breathing.
Fire Chief Scott Kettelle says air tests came back negative for carbon monoxide and other gases. He believes the issue is related to the store’s heating, ventilation and air conditioning system.
Investigators are continuing to search for the cause of the irritation.
