When loading and securing a boulder, it should be:

• All of these are requirements.
• Supported on at least 2 pieces of 4in x 4in hardwood blocking, extending the full width of the boulder.
• Placed on the vehicle with its largest or flattest side down.
• Placed on symmetrical hardwood blocking that extends 3/4 of the length of the boulder.

Requirements

Place each boulder on the vehicle with its flattest and/or largest side down.

Support each boulder on at least two pieces of hardwood blocking (at least 10 cm x 10 cm (4 x 4 in) that extend the full width of the boulder.

Place hardwood blocking pieces as symmetrically as possible under the boulder so they support at least 3/4 of the length of the boulder.

When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group, a crosswise tiedown should be used every how many feet?

• 6
• 3
• 10
• 15

As a group

Place lengthwise tiedowns over the group of pipes:

Either one 13 mm (1/2 in) chain or wire rope,

Or two 10 mm (3/8 in) diameter chain or wire rope

Place one crosswise tiedown for every 3.0 m (10 ft) of load length.

Either attach the side-to-side tiedown through a pipe

Or pass the tiedown over both front-to-back tiedowns between two pipes on the top tier.

When securing metal coils, it is acceptable to use nailed blocking or cleats as the sole means to secure:

• Chocks
• It is not acceptable.
• Nailed wood cradles
• Timbers

When securing concrete pipe up to 45 inches loaded crosswise, tiedowns through the pipe must be:

• Nylon rope.
• Chains
• Straps.
• Wire.

Specific securement methods are required for boulders that:

• Weigh more than 11,000 lbs, or have a volume of more than 2 cubic meters.
• Have more than five distinct sides.
• Weigh more than 5,000 lbs, or have a volume of more than 1.25 cubic meters.
• Weigh more than 5,000 lbs, or have a volume of more than 4 cubic meters.

The requirements in this section apply to any piece of natural, irregularly shaped rock that:

Weighs more than 5,000 kg (11,000 lb.) or has a volume greater than two cubic meters

Is transported on an open vehicle or in a vehicle whose sides are not designed and rated for the transportation of boulders.

When securing concrete pipe with a diameter of more than 45 inches loaded crosswise, how many tiedowns are required through each pipe at minimum?

• It depends on the weight of the pipe.
• 3
• 1
• 2

When securing rolls of paper with eyes vertical, how many points of contact are required to consider a roll secure?

• 1
• 3
• 2
• 4

Usually the roll is secure if a paper roll has 3 well-separated points of contact with the vehicle, other rolls, or other cargo.

When loaded cement pipe over 45 inches in diameter, which pipes should be blocked, wedged, or otherwise immobilized?

• Front and rear.
• It depends on the weight of the load.
• Rear only.
• Front only.

When calculating directional forces, 'g' is expressed as:

• The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
• The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
• The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
• The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.

As part of their pre-trip cargo securement inspection, drivers should:

• Make sure cargo is properly secured.
• Inform carrier of any inadequate packaging.
• Check for anything that will obscure their vision.
• All of these apply.
