COAL HANDLING SAFETY - AMETEK Land

coal and the high temperature inside the mill lead to rapid oxidation of the coal. This results in further heat build-up and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air.

Standard Practice for Manual Sampling of Stationary Coal ...

Sampling technicians must never work in coal that is piled or in railroad cars over hoppers and/or feeders or where there is the possibility of the coal being eroded from beneath them. Sampling should never be performed near a face of a stockpile where the face extends upward at an angle greater than the angle of repose of the coal. 7. Procedure
