"Due to the reports of a gas odor at the high school building today students were relocated to the middle school for precautionary reasons," reads the statement. "After a thorough investigation National Grid and the Melrose Fire Department have determined that it was safe for all students and staff to return to the building.
"There is however, some repair work that needs to be done which will require the HVAC system to be shut down. School administrators have decided to dismiss students at 10:00 a.m. on Monday, November 5th since the building will be without heat, air intake and gas."
The statement also added that there will be no school on Tuesday due to election day and a scheduled Professional Development Day for all staff in Melrose.
High school students will resume normal schedule on Wednesday, according to the statement.
