Martin Marietta Materials, Inc. safety activity

Employee's hand was pinched between a plate of steel and a block of wood resulting in a laceration approximately 2.5 cm that required stitches.

A tree fell on mine property due to high wind, causing it to fall on a powerline, causing it to arc. This resulted in two brush fires to start burning on the mine property.
