GORHAM -- The students of Robie Andrews Hall were allowed back into their rooms around 12:30 a.m., after a chemical spill prompted the evacuation of the building last night.

The co-ed dormitory houses about 200 students, all of whom were evacuated from their rooms. The culprit was 20 gallons of silver nitrate, a poisonous chemical used in photography development.

The four people who came in contact with the chemical and were sent to the hospital for observation were released shortly after without being harmed.
