|Drill with Lithium-Ion Battery Causes House Fire
|By Bay District Volunteers
|January 9, 2024
Lexington Park - In the early hours of Tuesday, January 9, 2024, at 2:49 a.m., units from Bay District (Stations 3&9), NAS Patuxent River, Second District, and Leonardtown were dispatched to a structure fire in the 45000 block of Edge Mill Court.
The incident was initially reported after an alert from an alarm company regarding a residential smoke alarm. Subsequently, a 911 call was received from the homeowner reporting that the house was filled with smoke.
Upon arrival, emergency crews found smoke emanating from the two-story residence. A prompt and thorough investigation revealed a fire involving a "Flex" branded Impact drill, battery, and charger.
Firefighters extinguished the fire within a 5-minute timeframe and checked for extension, which was fortunately not found.
The collaborative response of the firefighting teams highlights the effectiveness of their training and coordination in swiftly mitigating the incident.

Lithium-Ion Batteries - Frequently Asked Questions
Why are lithium-ion batteries flammable?
Lithium-ion batteries store a lot of energy in a small amount of space. When that energy is released in an uncontrolled manner, it generates heat, which can turn certain internal battery components into flammable and toxic gases.
How do fires from lithium-ion batteries start?
Lithium-ion battery fires happen for a variety of reasons, such as physical damage (e.g., the battery is penetrated or crushed or exposed to water), electrical damage (e.g., overcharging or using charging equipment not designed for the battery), exposure to extreme temperatures, and product defects.
What are some unique dangers of lithium-ion battery fires?
Heat, smoke, the release of toxic gases, and the potential for explosions are the dangers associated with lithium-ion battery fires.
Where is the safest place to charge batteries in e-bikes and electric vehicles?
When it comes to e-bikes, e-scooters, and electric vehicles, the safest place to charge these devices is outdoors away from any structure or enclosure and not in direct sunlight. Do not charge a battery when either the charger or the battery is damaged. Do not store batteries in extremely hot or cold locations or in an area that blocks the only exit out of to a room. And do not attempt to modify the battery or charger.
Once the batteries catch fire and water is applied to them, does it make the fire worse because lithium in the presence of water creates combustible hydrogen?
Firefighters should use water to fight a lithium-ion battery fire. Water works just fine as a fire extinguishing medium since the lithium inside of these batteries are a lithium salt electrolyte and not pure lithium metal. Confusion on this topic stems from the fact that pure lithium (like what you see in the table of elements) is highly reactive with water, while lithium salts are non-reactive with water.
How should lithium-ion batteries be disposed of?
Lithium-ion batteries and the devices that contain them should not go in household garbage or recycling bins. They can cause fires during transport or at landfills and recyclers. Instead, lithium-ion batteries should be taken to separate recycling or household hazardous waste collection points. Many stores that sell large quantities of lithium-ion batteries will have a recycling program where you can return the batteries there. Your local waste management or recycling center should be able to take lithium-ion batteries as well.
