Most engines come equipped with a wheel chock mount.
OSHA Requirement 1910.178(k)(1) states, "The brakes of highway trucks shall be set and wheel chocks placed under the rear wheels to prevent the trucks from rolling while they are boarded with powered industrial trucks.
Two wheel chocks, mounted in readily accessible locations, each designed to hold the fully loaded apparatus on a 10 percent grade with the transmission in neutral and the parking brake released.
1. Do you use them regardless of whether you are on a grade?
2. What do you do to remind you that you "chocked" the tires?
3. Do you tether your chock to the engine to prevent loss?
4. Any insight about how to correctly use a wheel chock?
5. NFPA 1901 recommends using (2) wheel chocks, do you?
LOOKING FOR A WRITTEN SOP ON WHEEL CHOCKING APPARATUS, ANY ONE
2 wheel chocks, in front of and behind the tires, mainly on a grade or when the rig is in pump. We do not tether ours to the engine, but we are required to do a 360 degree walkaround of the apparatus before the Engineer takes his seat.
If it's not rolling it's chocked
