The Ethel Walker School in Simsbury moved students from the school to the chapel Tuesday morning as crews dealt with an issue with a gas line.
A school official said some staff members from the school were doing maintenance when they disrupted a gas line around 8:30 a.m. Tuesday.
Students and staff have been waiting in the chapel while the gas company makes repairs.
No one is in danger, school officials said.
Crews from the Simsbury Volunteer Fire Company said the situation is under control and CNG has secured the leak.
