Abstract :
The objective covers the documentation of preventive and control measures implemented and assess their effectiveness. Head Race Tunnel of Middle Bhotekoshi Hydroelectric Project-102MW (MBKHEP) was selected for the study. This study has been carried out by utilizing the data collected from the duly filled semi structured questionnaires by the Employers’, Consultants’ and Contractors’ personnel. Moreover, key informant interview and focus group discussion were also used. The major causes of accident were lack of skills/ knowledge and carelessness of workers. It was responded that Personal Protective Equipment (PPE) was not sufficient. The provision of safety engineer/ officer was compiled as per contract document though safety officer was not monitoring the safety measures effectively. Drilling and blasting were the most risky activities in tunnel construction. Geological scaling, mapping and support works including wire mesh installation, rock bolting, and safety shot circuit were also the equally risky activities in the tunnel construction. The medical examination practice of the workers was lacking at site. Till July 2017 only one accident was occurred inside Head Race Tunnel due to fall from working platform with minor injury. It was free from fatality and death. Average absenteeism due to health problem and accident was only 1.81 days per month and hence, preventive and control measures used can be regarded as effective. The management commitment to the health and safety along with worker participation are essential for successful construction project. Preventive and control measures should be planned and implemented as per the risk level of hazards
