B. It shall be installed so that the minimum structural capacities will support a dead load weight of 18,000 pounds. The operator shall provide evidence of certification by attaching documentation to the cab or canopy or providing such information on a plate, or by keeping a letter of certification available for review by an authorized representative of the Chief.
C. The deck plate or mounting shall withstand the same load which the cab or canopy is designed to support.

F. When a bolt or pin is used as an integral part of the cab or canopy, the bolt or pin shall withstand more than the shear weight of the designated load capacity.
G. Any other act or practice resulting from the installation and use of cabs and canopies considered by the Chief to be hazardous to the operator of the equipment or other mine personnel will result in appropriate enforcement action to ensure corrective measures are taken by the operator.
