This is Vernon. He is an electrician.
Electricians work with the wires that carry electricity.
Electricity does many good things, but it can be dangerous. In this picture he is 'pulling the wires' for the high voltage lights that will be used in the front section of the new wing. He is one of the workers who works in the old part as well. The electricity in the old and the new parts of the building will be connected, just as the plumbing, heating and cooling will be. That is why some of the ceiling tiles are missing from the lower and main halls of the school.
