Which of the following is an important safety guideline when dealing with batteries?
Key safety guidelines for battery handling include avoiding short circuits, preventing thermal exposure, and using manufacturer-approved chargers. Always store batteries in fireproof containers at 50-80% charge in cool, dry environments. Wear insulated gloves and eye protection when handling damaged cells. For lithium batteries, adhere to strict voltage limits (e.g., never discharge below 2.5V/cell) and use BMS-protected systems to prevent thermal runaway.

What precautions prevent battery fires during handling?
Critical precautions involve short-circuit prevention and thermal management. Insulate terminals during transport, avoid metallic contact between cells, and never stack loose batteries. Pro Tip: Place lithium batteries in LiPo-safe bags—these contain fire spreads for 30+ seconds if thermal runaway occurs.
Beyond physical safeguards, electrical mismanagement causes 43% of battery incidents. Always use torque-limiting tools when connecting terminals—over-tightening damages seals, risking electrolyte leaks. For example, Tesla’s service manual specifies 8-10 N·m for Model 3 battery busbars. But what if you’re working with older lead-acid batteries? Ventilation becomes critical—hydrogen gas concentrations above 4% become explosive. Transitional tip: Rotate battery banks monthly to equalize terminal corrosion.
| Risk Factor | Lithium Batteries | Lead-Acid |
|---|---|---|
| Fire Trigger | Overcharge >4.25V/cell | Hydrogen gas + spark |
| Extinguisher Type | Class D | CO₂/Water mist |
How should damaged batteries be stored?
Isolate damaged units in ventilated fire cabinets with sand barriers. Lithium batteries require non-conductive storage (plastic bins) at 30-50% charge. Pro Tip: Mark containers with hazard symbols and last inspection dates for emergency responders.
Practically speaking, swelling or hissing batteries need immediate quarantine. Did you know a punctured 18650 cell can reach 900°C within 60 seconds? Transitional protocols matter—NFL teams now store game-day battery banks in concrete bunkers after a 2022 charging cart explosion. For households, a metal trash can filled with vermiculite works temporarily.
| Damage Type | Storage Solution | Max Duration |
|---|---|---|
| Swollen | Fireproof locker | 48 hours |
| Leaking | Acid-neutralizing tub | 24 hours |

FAQs
No—water accelerates lithium reactions. Use only Class D extinguishers or submerge in sand until cells cool below 100°C.
Is it safe to charge bulging batteries?
Absolutely not—swelling indicates internal shorts. Immediately power down and contact hazardous waste disposal.
