A fire that broke out Monday evening at the Matanuska-Susitna Borough Central Landfill was likely caused by an exploding lithium battery, borough officials said Tuesday.
The fire burned deep into a construction and demolition debris cell as 17 water tenders from fire departments across the borough battled the blaze until 1:30 a.m., when it was fully extinguished, landfill officials said in a social media post. It was contained about 11 p.m., Emergency Services Director Ken Barkley said.
The blaze was initially contained within the construction debris, Barkley said. Photos shared Monday by the Mat-Su Borough showed that it spread to tires near the cell. The was not at risk of spreading beyond the demolition debris cell, Barkley said Monday.
The battery likely triggered the blaze as crews compacted the cell Monday evening, landfill officials said in the social media post.
Landfill rules require lithium batteries to be separated and disposed of in the hazardous waste section. There is no charge to dispose of lithium batteries, officials said.
