The road tunnel construction is highly complex. It inherently involves many risk-prone activities like excavation and lining, transportation of materials, use of explosive, drilling and blasting, scaling and mucking, ventilation and noise protection excavation, handling of tunnel machinery etc. The risk increases especially, construction in poor rock condition and longer length tunnel. Hence, the safety during construction is crucial. The critical literature review indicated that very few studies available for safety management of road tunnel during construction in India. So the study presents the case study of safety management of two different road tunnels, (i) Chirwa Ghat twin tunnel project near Udaipur and (ii) Kuthiran tunnel in Kerala, in detail. It will provide more insight of safety during construction and it also identifies gap in safety practices for improvement. The study describes the general and specific requirements for safety during the construction. It also throws enough light about the other allied services necessary for the safety of the road tunnel. The basic aspect of safety such as personal protective equipment, access control equipment, lighting, ventilation and safety system at workplace are presented in detail. Tools and methods for identifying risk in working conditions are also discussed in the study. Then the observations have been discussed for all general and specific requirements on both the tunnels and gaps are identified in the field practices. The remedial measures and precautions for various high risk involving activities like drilling and blasting are presented in the study Thus the study will contribute to provide detailed insight of safety scenario during road tunnel construction and identifies the gaps for improvement in current field practice in India.
