No one was injured and damage was minimal when insulation on piping caught fire Thursday evening at the Ranbar Technology plant at 403 Manor-Harrison City Road.
Plant manager Lenny Kulbacki is investigating the cause of the fire, which broke out as employees were filling a drum with resin used in the paint industry.
The company makes coatings and resins.
Kulbacki said the minor fire set off an alarm and was quelled with a hand-held extinguisher.
Manor Fire Chief Greg Stutz said four employees working the final shift before an Easter weekend break were evacuated as firefighters responded at 9:36 p.m.
Units from Harrison City, Claridge, Penn, Adamsburg, Irwin and Westmoreland City responded along with the Westmoreland County Hazardous Materials response team.
