Eleven children became mini-medics after receiving first aid and CPR training at the Amazon fulfilment centre in Sutton.
Amazon employees took their children to the centre to take a course that introduces children to health knowledge and lifesaving skills, such as showing them how to administer first aid.
General manager Vivek Khanka said: “The young learners gained vital skills, which could prove invaluable should they ever need to act as first responders.”
Ruth Singleton, who provided the sessions, added: “The children who attended our Mini Medics event were really enthusiastic and I had a great time teaching them about first aid. Having such skills could make all the difference in an emergency.”
