Key Hazards
- Thermal runaway and battery fires
- Chemical exposure from damaged cells
- Fire spread due to improper storage or charging
2–3 Minute Talk Script
Lithium battery safety matters because lithium-ion batteries can fail violently when damaged, overheated, or improperly charged. A battery that seems normal can rapidly escalate into a fire event.
Inspect batteries before use and charging. Swelling, cracks, punctures, or leaking indicate the battery should be isolated and removed from service. Do not continue to use questionable batteries.
Charge batteries only with approved chargers and avoid charging near combustibles. Keep batteries out of direct sunlight and away from heat sources to reduce overheating risk.
If a battery overheats, smokes, or smells unusual, treat it as an emergency. Follow your site procedures and notify supervision immediately.
Safety Reminders
- Do not use or charge damaged or swollen batteries.
- Use only approved chargers and follow charging procedures.
- Store batteries away from heat and combustibles.
- Report overheating, smoke, or unusual odors immediately.
Ask the Crew
- Are any batteries showing damage, swelling, or unusual heat?
- Are we charging and storing batteries in a safe, controlled area?
