Safe Work Practices

Proper handling and work practices are the best preventive measure for limiting and controlling lithium ion battery incidents.  Safe work practices start with personnel using proper personal protective equipment (PPE) and following handling procedures.  Many incidents occur during device disassembly.  Risks of rupturing a battery is high so batteries must be discharged before doing any device tear-down.  Get more details in the Lithium Battery Safe Work Procedure and in Electronic Disassembly.


Store lithium cells and batteries in a well-ventilated, dry area.  Batteries should be stored with less than 55% charge, but not less than 10% and in the original packaging.  If batteries are depleted, store in a separate location from partially charged batteries.  Do not stack batteries or place anything on top of batteries. 


Transport lithium cells and batteries in their original containers and packaging, if possible. If this is not possible, use a non-conductive carrying tray with individual compartments for each cell to prevent damage during transport.  Learn more


Lithium batteries present a potential fire hazard if not packaged and shipped properly.  They are also subject to shipping restrictions. Refer to the EHS web page for more details, or contact Apple Shipping.


Unwanted lithium ion batteries are both hazardous waste and require special disposal procedures.  Please contact to get battery disposal bins.  Follow these procedures before disposing of batteries.

  • Discharge batteries and cells before disposal.
  • For cells, cut the tabs off one at a time before disposal.
  • For batteries, cover terminals before disposal.
  • If the cell or battery has been damaged, contact EHS to specially manage it as hazardous waste.
  • Consult in order to be provided the DOT regulations or internal Apple Shipping documents for lithium cell and battery transportation and disposal requirements.
  • If the battery or cell is a sensitive prototype, contact EHS for disposal arrangements.

Battery Incidents

Preparation is key to safe response to a battery incident.  Contact to obtain a sand bucket and compromised battery bin.

Look for these signs of a compromised battery:

  • Battery swelling or bulging of the device’s case
  • ­Separation of battery pouch from device
  • Failure or damage to the battery’s protective unit
  • Signs of heat or smoke damage
  • Obvious signs the battery has vented
  • A hot battery or cell

If possible and safe to do so, get the compromised battery in a sand bucket and call contact for pick-up.

If the battery is in a not safe to handle state, evacuate the area and call Security at 4-3333 to initiate an emergency a response.
