Downingtown STEM Academy reopened last Tuesday after a Monday night fire closed the building down on Monday. The incident occurred Monday night at some point before 9 p.m., authorities said. More than 100 firefighters responded to the scene of the blaze, which was described as “small.” The fire was contained to the fume hood in the science prep room, according to Superintendent Emilie M. Lonardi. There was no fire or smoke damage done to the school, officials added. Six computers were damaged by water from the sprinkler system, and two engineering rooms of the basement floor suffered some water damage. Staff cleaned up the water on Sunday night. A hired restoration crew of 52 technicians spent the next 24 hours working to make the school ready for classes on Tuesday. No injuries were reported in the incident.
