The study concludes that the risk from trench excavations is not low. A Working Group was therefore formed under the Utilities Technical Liaison Committee (UTLC) of Highways Department to prepare guidelines to promote safe practice for trench excavations. This document presents the recommendations of the Working Group as part of the Government’s continuing effort to promote a safe and healthy working environment for all personnel in construction sites and others who may be affected by the works.
