NOTE: "Fall of ground (from in place)" includes MSHA's Accitent/Injury/Illness classifications for "Fall of face, rib, pillar, side, or highwall (from in place)" and "Fall of roof, back, or brow (from in place)." Nonfatal injury cases classified under "Machinery" were reclassified as a "Fall of ground (from in place)" if the source of the injury was "Caving rock, ore, etc." This reclassification is consistent with how MSHA classifies similar incidents which resulted in a fatal injury. Sum of percentages may not equal 100 due to independent rounding. Excludes office employees. Data Source: MSHA
