Lithium batteries are part of everyday life. They power our phones, computers, cars, tools, and—within the motion picture and television industry—provide essential energy for cameras and other critical equipment.
When used and stored correctly, lithium batteries are generally stable and perform as intended. Problems arise, however, when proper handling and storage procedures are not followed. Even a simple drop or heavy jolt can cause internal damage, potentially leading to overheating or fire.
Unlike conventional fires, lithium battery fires behave very differently. They can enter thermal runaway—a chain reaction of uncontrolled heating that may result in fire or explosion. Once thermal runaway begins, these fires can spread rapidly, burn longer, require large amounts of water to extinguish, and emit toxic fumes that pose serious risks to both occupants and firefighters. In some cases, batteries can even reignite after the fire appears to be out.
Creating a Safer Work Environment
Following best practices can significantly reduce risk:
- Purchase or rent batteries only from reputable dealers
- Ensure batteries are properly maintained and regularly inspected
- Use only chargers specifically designed for each battery
- Charge batteries in well-ventilated areas, away from combustible materials
- Never leave batteries charging unattended
- Store batteries in fire-rated, noncombustible cabinets when not in use
- Store batteries in areas equipped with smoke and heat detectors
- Do not store batteries in primary or secondary exit pathways
- Avoid exposing batteries to extreme heat or cold
- Remove batteries from service as they near end of life or show visible damage
Battery manufacturers and local fire departments are valuable resources for guidance on safe storage practices and appropriate fire extinguishers to keep on site.
With a little proactive care and attention, lithium batteries can continue to power our work safely and reliably.
