The mining industry understands the value of sharing safety learnings as shown by the use of safety shares at meetings, collection of data on incidents and close calls as well the distribution of MSHA's Fatalgrams. These are excellent methods of keeping safety to the forefront - but there is one piece that is missing: the sharing of the critical controls that companies have established to prevent or mitigate accidents and injuries. The University of Arizona, through a grant with the National Institute for Occupational Safety and Health (NIOSH), has initiated a series of workshops to solicit and document these established critical controls, so they can be shared across the industry. The first workshop included 12 geotechnical experts and resulted in 81 documented critical controls. This paper will discuss the workshop methods, results of the first workshop as well as learnings for managing future workshops.
