The investigation continues into yesterday morning’s massive blaze at QPS Mechanical in Chatham.
As many as 20 fire fighters helped to tackle the flames, which broke out just before 9:30 yesterday morning.
Two employees were taken to hospital to be treated for smoke inhalation.
The Ministry of Labour and the Ontario Fire Marshal’s office have both been notified.
At this point, officials still aren’t sure what sparked the fire, and say the investigation is expected to continue for some time.
