Units from Kerry Fire and Rescue Service dealt with a fire at a factory just outside Killarney.
The fire broke out at the Tricel factory in the Ballyspillane Industrial Estate before midday.
A number of units were called to the scene.
All employees were evacuated safely from the factory and the fire was isolated to one part of the building where it was brought under control.
Tricel produces plastic products such as wastewater tanks.
The fire sent large plumes of smoke into the sky above the town.
