Workers in hazardous environments such as mining are continually exposed to dynamic and unpredictable hazardous conditions. For instance, slipping and tripping hazards are created by mine conditions such as water, mud, uneven floors, and mine floor obstacles. Moving machinery in the confined mine environment creates pinning and striking hazards. These environments also have limited visibility due to line-of-sight restrictions, poor lighting, airborne dust, and smoke. Workers must be able to constantly monitor their hazardous environments in real time so they can be aware of impending and existing dangers.
