If you are planning to do this yourself, be aware that not all detecting devices actually detect all the different individual service that may be present in the ground. In the case of a gas service pipe, this should be a minimum of 375mm deep on private ground and a minimum 450mm deep when laid under footpaths and roads. When running a gas main supply pipe underground the HSE specifies it should be at least 750mm deep in a verge or road, but 600mm deep for a footpath.

Separation of common services (above and below In addition to the requirements set forth in subparts D and E of this part (29 CFR 1926.50 - 1926.107) to prevent exposure to harmful levels of atmospheric contaminants and to assure acceptable atmospheric conditions, the following requirements shall apply: Where oxygen deficiency (atmospheres containing less than 19.5 percent oxygen) or a hazardous atmosphere exists or could reasonably be expected to exist, such as in excavations in landfill areas or excavations in areas where hazardous substances are stored nearby, the atmospheres in the excavation shall be tested before employees enter excavations greater than 4 feet (1.22 m) in depth. Where tunneling is not an option, the existing concrete paving shall be neatly cut with an angle grinder to deliver smooth, uniform edges.

Pretty much any and all drainage work is notifiable work e.g. To complete all of the safety aspects fully, any new underground cables, for example, to run a new supply out to a garage outbuilding, the buried cable would be required to run back to a 30mA RCD, so if there is any slight issue, the RCD would then trip and cut power preventing any serious injury. 0000077180 00000 n Plans give only an indication of the location, and number of underground services at a particular site. Once the cabling is in place the ducting is then capped and sealed to prevent. The precautions necessary to protect employees adequately vary with each situation, but could include special support or shield systems to protect from cave-ins, water removal to control the level of accumulating water, or use of a safety harness and lifeline. 3266 0 obj<>stream Webunderground services, and in doing so to minimise risk to personnel who are involved in carrying out this work. Angle of crossing shall be between 45 and 90 degrees.
