I found a battery in a device having ruptured. It seems like liquid and white crystals have formed on the surfaces around it. What should I do?

In the unlikely event of a rupture or a leak, isolate the device such that the leak doesn’t come into contact with yourself or any sensitive goods. Please keep the device and batteries unchanged as we may need you to send these to us if we need to investigate the matter further. Clean all other contaminated surfaces with water and soap. If contact with the eyes occurs, rinse with water for 15 minutes and seek medical assistance.
