Avoiding Danger From Underground Services HSG47 is a guide produced by the Health and Safety Executive and it does what it says on the tin. It is designed for people involved in “commissioning, planning, managing, and carrying out work on or near underground services”. It is also of use to owners and operators of such services. This is the latest (third) edition and was updated in 2014.

The three basic elements of working safely during an excavation are planning the work, locating and identifying buried services, and safe excavation. As they say, underground services are widespread, and so you should assume they are present unless you have been shown otherwise. At Sygma Solutions, we would take that one step further because that could imply that if you have obtained plans (STATS) from service providers in the area which show that there is nothing where you are about to dig, that is not necessarily the case.

Plans May Not Be Accurate

Unfortunately, not all plans are accurate, they may not be complete, they may also be out of date. Just as one example, a utility may have employed contractors to install a service and the instructions may have been that it should be five feet below the surface, and that is what the plans will show.

If you are only going to dig down three feet you may believe that it is safe to do so. However, it has not been unknown for a contractor to cut corners in order to save time and money, and it is always a possibility that the contractor only installed the service at a depth of two feet. This is just one reason why, although you should always obtain plans whenever they are available, you should never rely on them as gospel. They can only ever be used as a guide.

It is absolutely essential to carry out a survey on the ground in every instance before digging. This is done using the CAT and Genny in combination, but even then, you need to be aware that they have certain limitations. As another simple example, you may use them and get a negative result but that may not mean that nothing is there. If the ground is such that the equipment can only read to a depth of, say, three feet, and you need to dig down five feet, you may get a negative reading and proceed on that basis. But there could be a service at a depth of four feet!

The answer is to dig down cautiously a foot or so and then take another reading. Then another foot, and so on. This time you may get a positive reading.

These are the sorts of things that we teach on our courses at Sygma Solutions. We have over 100 years of combined experience of excavation work and surveying and we know the sort of things that can happen.
