March 24, 2017 - Slips, trips, and falls are prevalent in all types of mining operations. No specific guidelines or regulations are provided by the Mine Safety and Health Administration for the use of inclined grated metal walkways in mining plants. Mining companies may be using walkway materials that do not provide sufficient friction, contributing to slip and fall injuries. The National Institute for Occupational Safety and Health (NIOSH) conducted a research study to determine the slip potential for three different types of grated metal walkways during walking in diverse conditions. The number of slips increased when the inclination angle reached 10° and above. Of all materials tested, the diamond weave grating was found to have the best performance at all inclines when contaminated or dry. A high number of slips occurred for the perforated grating and serrated bar grating at 20° when contaminated. Results of this study suggest that the diamond weave grating provides significantly better slip protection compared to serrated bar and perforated gratings, especially at inclines greater than 10°. This infographic presents recommendations for preventing slips and falls when working on inclined surfaces.
