OSHA standard 29 CFR 1910.178 requires vehicle operators to set their truck and trailer brakes and block their wheels to prevent vehicle movement. The standard notes that chocks should be placed under the rear wheels, which means two chocks should be used – chocking just one wheel isn’t enough.
Do I need to chock both sides of trailer?
Chocking your wheels is such a simple task and is an extremely important safety measure. If you don’t have chocks or happen to forget them, you can shove a rock in front of the tires to keep the tires from rolling and keeping your rig in place. To be extra safe, I recommend you chock both sides of each trailer.
Why do you chock wheels?
Wheel chocks are used for safety and accident prevention. Chocking, also known as blocking, is done to prevent trucks and trailers from unintentionally moving, like rolling or overturning, while workers are loading, unloading, hitching, unhitching or servicing the vehicle.
Do you have to chock both wheels?
It is best practice to chock both the front and back wheels on both sides of the vehicle. Sometimes it’s even better to chock the front and back of each tire. Wheel chocks are an inexpensive way to ensure the safety of those working in and around the truck and trailer.
Are plastic wheel chocks safe?
Polyurethane plastic is the second most common material for wheel chock. They’re better at resisting cuts, blunt damage, water damage, and wind damage than rubber chocks, and they’re lighter-weight than rubber or aluminum. But, plastic wheel chocks are not as high-strength as aluminum or steel alloy chocks.
Does RV have to be perfectly level?
How level does an RV need to be? An RV should be level within 1 – 2 degrees from the plum. Visually, this would be about half a bubble on a bubble level. It should be leveled from side to side and then from front to back.
What can I use as wheel chock?
Bricks would be safe enough as wheel chocks because the rubber tyre spreads the load. (Imagine trying to chock a railway wagon with a brick however, and it would be another matter.) But all the same, the proper wedge-shaped blocks are probably best.
