A customer brings in a smartphone with a noticeably bulging case. Upon inspection, you confirm that the device's battery is swollen. What is the immediate next step to ensure both customer and workplace safety?
Begin to charge the device to test if it can still hold a charge
Carefully remove the battery from the device to a safe location and advise the customer not to charge or use the device
Place the device in the freezer to prevent further swelling until you can inspect it
Press on the swollen battery to verify that the swelling is not causing any false bulging of the case
Removing the battery, if safely possible, is the immediate next step to prevent any further risk of injury or damage from the swollen battery potentially rupturing or catching fire. It's important to do this in a manner that does not puncture or bend the battery further. The other options are not immediate next steps and could either delay the necessary response to a potentially dangerous situation, or put the technician and the device in further unnecessary danger.
