My son is 12 and he just accidentally touched a plug socket which appears broken as it looks like it’s been on fire at some point and it has metal sticking out of one of the holes. He screamed and ran around screaming thinking he had been stung or bitten until we went to take a look. It’s in our garage and we have never ever noticed this plug socket before we were sorting out the camping stuff as we go camping soon. Will he need to go to A&E? He seams fine now there is no mark where it happened on his hand. But just since it ceme direct from a plug socket I assume it’s dangerous?
