Lancaster and Morecambe College was evacuated on Friday morning after a car ploughed into a car and then a gas main.
Fire crews were called out at 9am following a 999 call that a Vauxhall Astra had hit a parked Audi A1 and then a gas main in the college’s car park off Torrisholme Road.
Lancashire police said that the 45-year-old driver of the Astra did not suffer serious injuries, but was treated at the scene for shock and whiplash.
The occupant of the Audi was unhurt.
Lancashire Fire and Rescue Service said there didn’t appear to have been a gas leak, but that the college was evacuated as a precaution.
A spokesman added that National Grid were on their way to switch off the supply and repair any damage.
The college has now closed and pupils have been sent home, but it will re-open on Monday.
Stuart Rimmer, the college’s director of quality said: “We have closed the college temporarily and sent pupils home due to there being no hot water or heating in the college, but we will re-open on Monday.
“The sports centre will be closed all weekend however, as we’ve got to replace a bit of pipework.”
PC Shaun Canning of the Road Policing Unit from Lancaster who attended the scene said: “It was extremely fortunate that the large gas mains pipe was not ruptured but remained intact considering the impact from the Astra.”
