When firefighters arrived they found smoke inside the building and worked to clear it out, no fire was located by firefighters.An investigation found that some of the batteries had overheated leading to plastic and wires melting.”There are multiple layers of safety integrated into the battery facility and the risk mitigation and safety systems worked as designed, detecting these modules were operating at a temperature above operational standards and triggering targeted sprinkler systems aimed at the affected modules,” reported the company in a press release.Since Saturday firefighters have remained at the facility as a precaution.“Lithium-Ion batteries can be unstable,” said Mendoza. According to an August 2021 report in the Journal of Energy Chemistry, “When operating, the electrodes produce heat, which might become uncontrollable during battery malfunction.”Mendoza also noted that the safety system at the facility worked as intended.On Sunday, hazmat crews from Monterey County Hazmat responded to the facility to test inside and outside of the building as well as the nearby water. No toxic chemicals were discovered by the hazmat crews.Mendoza said that there was no threat to the public.
