||Safe construction and maintenance of pipelines

||Many water supply, sewage, gas and other underground pipelines in Germany require enlargement and maintenance. Important requirements spelled out in German Ordinances (Safety Regulations for Construction Work - VBG 37 - see CIS 83-1147) and Standards (DIN 4124, see CIS 84-1126) on the safety of personnel engaged in pipelaying or in the maintenance of pipelines are discussed. During underground tunnelling operations, pipes of more than 80cm in diameter may be entered by personnel. For inspections and maintenance the minimum diameter for entry under certain conditions is 60cm and the recommendation is made here that the diameter of pipeline over 100m long be raised to 120cm. All tunnelling, shaft sinking or open-trench work requires prior assessment of soil conditions. All trench work next to roads must be adequately illuminated and marked.
