§ 33.289. Ramps and runways.

 (a)  Specifications. Ramps or runways used for vehicles shall have a width of not less than 12 feet. Timber guards not less than 8 inches by 8 inches shall be securely fastened on top of the runway along each of the outside edges.

 (b)  Railings. Ramps or runways, when used as passageways for workmen, shall be provided with standard railings.

 (c)  Ruts and holes. All ramps and runways shall be maintained in a safe and serviceable condition. When ramps and runways are formed on hard ground without the use of planking, ruts and holes greater than 2 inches deep are not permitted.

 (d)  Chockers. When the pitch of the ramp requires it, a man shall be along side a loaded truck with a chock provided with a strong handle for blocking a rear wheel in case the truck stalls or otherwise is forced to stop on the ramp. Workmen other than chockers shall be required by the main contractor or the contractor doing the excavation work to stay off ramps and runways when trucks are passing over them.

 (e)  Foot cleats. Where the incline of the ramp is too steep for safe walking, foot cleats, not more than 16 inches apart, shall be provided to prevent slipping.
