A Checklist Definition for Assessing Mechanical Risks Using NTP 330 in a Repavement Construction Process

In a construction project, such as a road repaving process, skilled and unskilled labor are the fundamental axis for the development of the project. Their intervention must be supervised by the probability of occurrence of occupational accidents due to the use of equipment, heavy machinery and tools required throughout the activities, which can have negative consequences on workers, manifested through temporary, permanent, and even fatal disabilities, and to contractors and employers, due to delays and economic losses in the project, in addition to possible sanctions by control agencies. Occupational hazards must be managed by a legal requirement in all countries. Hence, the need to identify, evaluate and propose risk control measures in all types of constructions. In this case, the study focuses on generating checklists to measure deficiency levels of mechanical hazards in the construction process of replacing flexible pavement with rigid concrete, according to the NTP 330 methodology, which is based on the application of the NTP 324 methodology of the National Institute of Safety and Health at Work (INSST) in Spain. These checklists will be the input for the assessment of mechanical risks by verifying the safety actions and conditions adopted in the construction project. Likewise, compliance with the requirements of these checklists will determine the basic requirements of the mechanical risk control process, prioritizing urgent prevention activities.
