MIAR^forest Reproducibility and Reliability for Assessing Occupational Risks in the Rainforest

The Method for the Integrated Assessment of Risks for rainforest (MIAR(forest)) is a specific methodology for assessing the risk of occupational accidents associated with working in native tropical forests. MIAR(forest) was validated for the results' reproducibility and the reliability of calculated risk levels through the Delphi approach. Two rounds of questionnaires illustrating ten scenarios of activities associated with the logging process in the Eastern Amazon's native rainforest (Brazil) were presented to forestry and occupational health and safety (OHS) experts. In the first round, the questionnaire was answered anonymously by 55 experts, and in the second, by 46. A percentage of agreement of at least 80% in each question was considered to close the process. Questions that did not meet the criterion in the first round were reassessed in the second round. The obtained results lead to the conclusion that MIAR(forest), an occupational accident risk assessment tool, has been effectively validated, demonstrating inter-rater reproducibility and reliability in determining risk values. These results highlight the objectivity and reliability of MIAR(forest).
