Handling Wet and Frozen Coal

SKU: CHHWF00CENDuration: 60 Minutes

Wet and frozen coal can create difficult problems for coal handlers, including clogging equipment and impeding or blocking coal flow. However, many of the problems resulting from wet or frozen coal can be greatly reduced, and sometimes entirely avoided, by following certain precautions, by properly using specialized equipment, and, in some cases, by planning ahead. This training program covers the types of problems caused by wet and frozen coal, as well as methods and equipment that are commonly used to avoid, minimize, or respond to these problems.
