County fire officials advise safety steps for lithium‑ion batteries after rising incidents

Martin County Fire Rescue officials told the Board of County Commissioners April 7 that lithium‑ion battery incidents are increasing in Florida and urged residents to adopt several safety steps to reduce fire risk and harm.

Deputy Fire Marshal Chris Hansen said latest state reporting shows a rise in lithium‑ion related incidents and that these fires differ from ordinary electrical fires because batteries can enter "thermal runaway," produce very high heat and can reignite hours or days after initial suppression. "Once they go into this state, they are unstable and can remain in that state," Hansen said.

Community Risk Reduction Specialist Josh Jenkins recommended practical steps: use only the charger that came with the device, charge on a firm, nonflammable surface out of direct sun, maintain at least 36 inches of clear space while charging, unplug devices when charging is complete, and look for swelling, hissing or unusual heat as warning signs. He also noted that standard ABC home fire extinguishers are not rated specifically for lithium‑ion battery fires and that some incidents require specialized response and storage at landfills and hazardous waste facilities.

Officials said county fire investigators have seen incidents involving mobility devices, hoverboards, golf carts and even an aircraft battery; they cautioned that fumes from a failing battery can be hazardous to health and recommended calling emergency services rather than trying to move a device that appears to be failing.

The presentation was informational and no board action was required; commissioners thanked staff and asked that guidance and links to disposal options be posted on county websites.
