(Greenfield, MA) — A Greenfield gas station had to close for most of yesterday after the fire suppression system unexpectedly deployed. Greenfield police and fire officials were called to the Speedway gas station on Federal Street shortly after one pm. No fire was present, but the suppression system ended up dumping white powder on a number of vehicles in the lot. The powder was cleaned up later in the day. No injuries were reported.
