Battery Storage and Handling

• Chemical burns from battery acid or electrolyte
• Electrical short circuits from tools, jewelry, or terminals
• Fire or thermal runaway from damaged batteries
• Hydrogen gas buildup during charging
• Strains from lifting heavy batteries
• Leaks, corrosion, or damaged battery cases

Batteries can create chemical, electrical, fire, and lifting hazards. Whether the battery is small, rechargeable, lead-acid, lithium, or equipment-mounted, it should be handled with care.

Workers should inspect batteries before handling or charging. Cracked cases, swelling, leaks, corrosion, heat, odor, or damaged terminals are warning signs that the battery may be unsafe.

Battery terminals can short if they contact metal tools, jewelry, chains, or other conductive materials. Workers should keep terminals protected and remove jewelry when handling batteries.

Lead-acid batteries can expose workers to acid and corrosive residue. Gloves, eye protection, face protection, aprons, and eyewash access may be needed depending on the task.

Charging areas should be suitable for the batteries being charged. Ventilation, fire protection, clear access, and separation from ignition sources are important, especially where hydrogen gas may be generated.

Lithium batteries require attention to damage and heat. Swelling, punctures, crushing, overheating, smoke, or unusual odor should be reported immediately and handled according to procedure.

Large batteries should be lifted with proper equipment or team lifting. Batteries can be heavy, awkward, slippery, and difficult to grip safely.

Safe battery storage and handling depends on preventing shorts, controlling chemical exposure, inspecting for damage, using proper charging practices, and keeping batteries organized and protected.

• Inspect batteries for leaks, swelling, corrosion, heat, or damage.
• Keep metal tools and jewelry away from terminals.
• Use PPE when acid or electrolyte exposure is possible.
• Charge batteries only in approved areas.
• Provide ventilation where charging can release gas.
• Use proper lifting methods for heavy batteries.
• Report damaged or overheating batteries immediately.

• Are any batteries leaking, swollen, hot, corroded, or damaged?
• Are terminals protected from short circuits?
• What PPE is needed for the battery type being handled?
• Is the charging area ventilated and free of ignition sources?
• Is mechanical help needed to lift or move heavy batteries?
