Pit Procedures

Rock Quarries can be dangerous. To ensure continuous safety for our customers and workers, please view and understand our pit procedures.

Check in at the Scale Shack
Before you can begin hauling rock, you will need to weigh-in at the Scale Shack (office) so we can get your vehicles tare weight. If this will be your first time hauling out of our quarry, you will need to sign a Site Specific.

One Lane Bridge
Prior to passing over the one lane bridge from either direction, announce your intentions of crossing using your CB on channel 7.

Loading Zone

Proceed to the loading zone to be loaded. If you must get out of your vehicle for any reason, a hard hat must be worn during all times that you are in the pit and out of your vehicle.
