The contract outlines the construction of 245km of 132kV single circuit overhead transmission line connecting the proposed substation at Kabarnet Nyahururu Narok Bomet. The Technical Specifications outlined in this section covers the scope of works for the
Risk of contact with overhead power lines is a major safety risk on construction and other work sites. The OSHA Electrical Selection and Use of Safe Work Practices Standard c) sets out requirements for working on or near exposed energized parts—whether by direct contact or via tools or materials—for general industry. Here are the XX things to check to
Avoiding danger from overhead power lines Guidance Note GS6 Fourth edition) This general series guidance note is for people who may be planning to work near overhead lines where there is a risk of contact with the wires and describes the steps you should take to prevent contact with them. The fourth edition makes the advice easier to follow and has brought the
