Any contractor undertaking any type of excavation work should understand the necessity for taking every precaution to avoid striking any type of underground service. Underground pipes and cables can be absolutely anywhere – even in places where you would least expect to find them. This means that no spade should even be inserted into the ground before a thorough survey of the area to be dug has been carried out using the appropriate cable avoidance tools.
The two main tools used to locate buried services are the CAT (Cable Avoidance tool) and the Genny (signal generator). Between them these two tools can locate very many underground services, but even so they have their limitations. This is why specialist cable avoidance training should be undertaken by anyone who has to locate underground services. It is not sufficient to purchase the tools and simply read the manuals.
Certainly, the manuals will show how to operate the two pieces of equipment, but there is nothing to beat being taught how to use them by a professional. When you go on a proper course with an instructor who knows everything there is to know, you may be surprised at some of the things that you learn that were not in the manuals. You will also get practical experience out in the field which is not just invaluable, but essential. Learning how to use the CAT and Genny in the classroom is one thing but putting into practice what you have learned will open your eyes to a whole lot more.
