      Highlights • A general RASH has been developed with risks classified into Safety Risks and Health Risks.
      • 11 factors representing safety risks and 8 factors representing health risks were identified.
      • RASH method resulted in superior accuracy for assessment of risk zones than the existing RA method.
      • RASH method gave fewer errors than the existing RA method for four different scenarios.
      AbstractIn this research Risk Assessment of Safety and Health RASH method for building construction has been developed with risks classified into Safety Risks and Health Risks. 11 factors representing safety risks and 8 factors representing health risks were identified based on field survey in Oman. 40 Safety and Health specialists were involved in carrying out risk assessment using the existing method of risk analysis RA and the proposed RASH method. It was found that RASH method resulted in superior accuracy for assessment of risk zones than the existing RA method. The accuracy by RASH was almost twice the accuracy by RA. The overall percentages of the correct answers for the four scenarios using the RASH method and the RA method were 72.5 percent and 40 percent respectively. The proposed RASH method gave fewer errors than the existing RA method for all scenarios. Two scenarios were found to be the most problematic ones with largest overestimation of risks occur when using the existing RA method. Wilcoxon Ranked Test showed that the two methods are significantly different (z = −3.357, p > 0.01). The new method RASH is statistically acceptable and it resulted in better response in terms of estimating the risk than the RA method.

      Background: Construction industry is among the most hazardous industries, and needs a comprehensive
      and simple-to-administer tool to continuously assess and promote its health and safety performance.
      Methods: Through the study of various standard systems (mainly Health, Safety, and Environment
      Management System; Occupational Health and Safety Assessment Series 180001; and British Standard,
      occupational health and safety management systems-Guide 8800), seven main elements were determined
      for the desired framework, and then, by reviewing literature, factors affecting these main elements
      were determined. The relative importance of each element and its related factors was calculated at
      organizational and project levels. The provided framework was then implemented in three construction
      companies, and results were compared together.
      Results: The results of the study show that the relative importance of the main elements and their
      related factors differ between organizational and project levels: leadership and commitment are the
      most important elements at the organization level, whereas risk assessment and management are most
      important at the project level.
      Conclusion: The present study demonstrated that the framework is easy to administer, and by interpreting
      the results, the main factors leading to the present condition of companies can be determined.
