Harry Buchanan, operations manager, said: "The aim of the 'Play Safe, Stay Safe' campaign is to remind children, for their own safety, that areas where people are working are not playgrounds. Our workers are specially trained to deal with the dangers of working in deep holes - children are not."
Harry continued, "Accidents will happen if children play close to vans, machinery and equipment. Fences, barriers and signs are there to protect people and they should not be moved or used as toys.
Just remember to 'Play Safe, Stay Safe'.
At National Grid, safety is our number one priority and to ensure we can continue to maintain the highest standards, we are asking anyone who notices that fencing, signs or barriers have been moved, or if you smell gas, please call the 24-hour National Gas Emergency Service on 0800 111 999*.
