San Luis Obispo County, Calif. – Early Friday afternoon, fire crews from the San Luis Obispo County Fire Department arrived at the Chicago Grade Landfill on Homestead Road east of Atascadero after reports of a fire that appeared to be caused by a lithium‑ion battery. The incident prompted a rapid multi‑agency response, including fire teams from Atascadero and Templeton, as well as a hazardous‑materials unit.
Initial response and fire suppression
Upon arrival, firefighters found the blaze confined to a small area of the landfill surface. Using water streams and foam, they were able to knock down the majority of the flames within the first hour. The fire’s intensity suggested a battery‑related ignition, a growing concern as more lithium‑ion devices are used in industrial and consumer settings.
Investigation and ongoing operations
To determine the exact origin of the fire, crews deployed an excavator to carefully dig into the landfill material. This method allows investigators to expose the suspected battery pack without disturbing surrounding waste that could reignite the fire. The excavator work is proceeding under the supervision of the fire department’s hazardous‑materials specialists, who are monitoring air quality and potential chemical releases.
Hazardous‑materials response
A hazardous‑materials response team is en route to the site to assist with any toxic by‑products that may have been released when the battery ignited. Lithium‑ion fires can produce hazardous gases, so the team will conduct air monitoring and, if necessary, implement containment measures to protect nearby residents and the environment.
Impact on the community
While the fire was largely contained, officials advised nearby residents to keep windows closed and avoid outdoor activities until air quality readings are confirmed safe. No injuries have been reported, and there are no immediate threats to surrounding properties.
Next steps
The fire department will remain on scene for several more hours to complete overhaul—ensuring all hot spots are extinguished—and to finish the investigation into the battery’s source. Findings will be shared with the public once the investigation concludes.
Public‑safety reminder
County officials remind citizens and businesses that proper disposal of lithium‑ion batteries is essential to prevent similar incidents. Residents are encouraged to use approved recycling programs for batteries and to report any suspicious odors or smoke near waste facilities promptly.
