Lightning can come through a brick wall as easily as through an open window. Radio aerials, electrical lines, telephone lines and water pipes are excellent conductors of electricity and lightning. If properly installed and grounded, they are not hazardous, and there is no need to disconnect plugs and aerials. But don't tempt fate. Just postpone that hot bath, telephone call or last bit of ironing.
Someone is struck by lightning .
Victims of lightning receive an electrical shock but do not carry an electric charge and can be safely handled. They may be suffering from burns or shock and should receive medical attention immediately. If breathing and pulse are absent, perform cardio-pulmonary resuscitation.
