Key Hazards
- Battery overheating, swelling, smoking, or catching fire
- Damaged batteries leaking or failing during use or charging
- Charging with incompatible or damaged chargers
- Short circuits from metal objects contacting terminals
- Improper storage near heat, water, combustibles, or direct sunlight
- Unsafe disposal of damaged or spent batteries
2–3 Minute Talk Script
Lithium batteries power tools, phones, radios, tablets, lights, meters, and many other devices. They are useful, but damaged or improperly charged batteries can fail violently.
Workers should inspect batteries before use and charging. Swelling, cracks, leaks, odor, heat, corrosion, impact damage, or melted areas are warning signs.
Only approved chargers should be used for the specific battery. Mixing chargers or using damaged chargers can cause overheating or fire.
Charging areas should be dry, ventilated, and away from combustibles when possible. Chargers and batteries should not be covered or placed where heat can build up.
Battery terminals should be protected from metal objects. Loose batteries should not be stored with keys, coins, screws, tools, or other conductive items.
Damaged, hot, swollen, smoking, or leaking batteries should be isolated and reported according to procedure. Workers should not continue using or charging them.
Batteries should be stored and disposed of according to manufacturer and site requirements. They should not be thrown loosely into regular trash if recycling or special disposal is required.
Safe lithium battery use depends on inspection, correct charging, proper storage, terminal protection, and quick action when a battery shows signs of damage or overheating.
Safety Reminders
- Inspect lithium batteries before use and charging.
- Do not use swollen, cracked, leaking, hot, or damaged batteries.
- Use only approved chargers.
- Charge batteries away from combustibles when possible.
- Keep terminals away from metal objects.
- Report smoking, odor, heat, or swelling immediately.
- Dispose of batteries according to procedure.
Ask the Crew
- Is the battery in good condition?
- Is the correct charger being used?
- Could heat build up during charging?
- Are terminals protected from short circuits?
- What is the response if a battery overheats or starts smoking?
