The term 'edge protector' refers to:

• A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
• A rail along the side of a vehicle that protects the side of the vehicle from impacts.
• A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
• A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.

What is the maximum angle recommended for tiedowns securing cement pipe loaded crosswise, relative to the deck?

• 45-90 degrees
• 180 degrees
• It doesn't matter
• 45 degrees

If the first pipe of a group in the top tier is not at the front of the tier beneath:

Attach an additional tiedown that runs rearward at an angle not more than 45 to the horizontal when viewed from the side of the vehicle, whenever practical.

Pass tiedown either through the front pipe of the upper tier or outside the front pipe and over both longitudinal tiedowns.

When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group,lengthwise tiedowns should be either one 1/2 in chain or wire rope, or:

• Two 3/8 inch chains or wire ropes.
• Two nylon straps with aggregate WLL of 50% the weight of the load.
• Two 1/4 inch chains or wire ropes.
• One 3/8 inch chain or wire rope.

When securing a load of lengthwise longwood logs weighing 42,500 lbs, what is the minimum aggregate WLL required for tiedowns? (rounded up to nearest lb)

• 10,000 lbs
• 8,550 lbs
• 21,250 lbs
• 7,085 lbs.

Aggregate Working Load Limit is defined as:

• A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
• The maximum weight of a load of rocks that a securement device can withstand.
• The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
• 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.

What is the minimum weight of a load of metal coils that requires specific securement practices?

• 2,268 lbs
• 50,000 lbs
• 5,000 lbs
• It depends on the size of the coils.

To prevent rolling, how many points of contact are required, at minimum, for a boulder resting on a rounded or partially rounded side?

• 4
• 2
• 3
• 5

Requirements

If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.

Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.

A tiedown is defined as:

• A rail along the side of a vehicle that protects the side of the vehicle from impacts.
• A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
• A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
• A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).

To secure paper rolls with eyes horizontal against rearward movement, you can use which of the following except:

• Blocking.
• The vehicle wall.
• Other cargo.
• Friction mats.

What is the minimum WLL of a tiedown used to secure logs?

• It depends on if you are hauling shortwood or longwood
• 50% of cargo weight
• 4,000 lb
• 1,800 lb
