The ongoing battery fire incident in Claregalway has now been contained.
Fire crews remain at the scene, and some firefighters were sent to hospital as a precaution.
The incident outside Xerotech at Claregalway Corporate Park is now in its third day.
It started early on Wednesday morning in a shipping container which held industrial batteries.
Yesterday, the corporate park itself was evacuated, as were two nearby schools, and around a dozen homes at Lakeview.
The difficulty hasn't been in extinguishing a conventional fire - but in keeping extremely volatile batteries cooled down so they don't reignite.
Crews have now isolated those batteries from the shipping container and placed them a skip of water.
There have been concerns over lithium contamination, and several firefighters were taken to hospital as a precaution after showing mild physical symptoms.
Air quality testing will determine if businesses can return to the corporate park later today - but emergency services will likely remain on-site for the foreseeable future.
