Toolbox Talk - Lithium Battery Safety

Lithium batteries are generally safe — but only when used, stored, and charged properly. Damage or defects can lead to fire or explosions.

Hazards to Watch For:

1. Physical damage: Dropping, crushing, or puncturing batteries can cause failure.
2. Heat: High temps (above 38°C / 100°F) or charging below freezing (0°C / 32°F) increases risk.
3. Improper charging: Using the wrong charger or not following instructions can damage the battery.
4. Thermal runaway: Heat from one cell failure can spread and cause fire or explosion.

Warning Signs:

1. Bulging or cracked batteries
2. Hissing, leaking, or smoking
3. Unusual heat while charging or in use

Safe Practices:

Use certified batteries and chargers (NRTL tested)

Follow manufacturer’s instructions

Remove devices from the charger once full

Store in a cool, dry place — not in direct sun or near flammables

Inspect batteries before use

Dispose of damaged batteries properly

In Case of Emergency:

If a battery shows signs of failure (smoke, hissing, overheating):

1. Stop using it immediately.
2. Move it away from flammable materials.
3. Evacuate the area if necessary.
4. Use the correct fire extinguisher: CO₂, dry chemical (ABC), or Class D (for lithium-metal).
5. Do NOT use water, especially on lithium-metal fires.
6. Report the incident to your supervisor and follow site emergency protocols.

Remember: Prevention is key. Handle with care — a small mistake can lead to a serious incident. Stay alert, stay safe.
