Using multiple complementary methods to develop ergonomics audits for mining operations

Although ergonomics audits are commonly used by consultants, the scientific literature on reliable and valid audits is sparse. This paper describes a multi-faceted methodological approach to developing ergonomics audits for three types of mining operations. The approach was derived from a validated audit (Ergonomics Assessment Program (ERNAP)) for aircraft maintenance operations. While there were contextual, regulatory, and intended end user differences, the general approach to establishing content validity through task analysis and workplace observations, surveillance data, and accepted practices and regulations proved to be effective, albeit with modifications. Analysis of fatality reports and desire for integration with existing mining safety approaches were two areas where the current approach differed from ERNAP.
