Don't go inside a substation to get anything out. 'Danger of Death' signs mean what they say. Instead, telephone the local electricity company and they can get it back for you. Use the number displayed on the substation, or look it up under 'E' for electricity in the phone book. Remember - you will not get into trouble for telling people about a problem.
What to do if something goes wrong:
If someone is injured inside a substation, call the emergency services on 999. Do not go into the substation to try and help them as you could also be injured.
