Define 'bolster':

• An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
• A crosswise load bearing structural component, particularly a part of a log bunk.
• A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
• A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.

All of the following are requirements for dividing vehicles over 33ft except:

• Each tiedown must be fastened below the logs on each side of the center stake.
• Vehicle must be divided by center stakes into sections of staggered length.
• Vehicle must be equipped with center stakes or comparable devices.
• Each tiedown must secure the highest log on each side of the center stake.

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
• 10
• 15
• 3

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 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.

When securing paper rolls with eyes horizontal, which of the following should be used to secure the rear-most roll?

• Wedges or chocks secured by some means in addition to friction.
• Secure blocking against rear doors.
• All of these are acceptable
• Secure roll against rear doors.

Note: Chocks, Wedges, or Blocking Securing the Front or Rear Roll - Hold in place by some means in addition to friction so they cannot become unintentionally unfastened or loose while the vehicle is in transit. This is often accomplished with nails.

Requirements for eyes crosswise: secure rearmost roll

Do not secure the rearmost roll with:

• Either the rear doors of the vehicle or intermodal container
• Or blocking held in place by those doors.

The maximum distance from the rear allowed for attaching mechanisms used to secure roll-on/roll-off containers is:

• It doesn't matter.
• 6 1/2 feet
• 2 feet
• 3 feet

Attach mechanisms used to secure the rear end of a roll-on/roll-off or hook lift container no more than two meters (6.5 feet) from the rear of the container.

Banding is:

• 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 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.
• Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
• 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).

When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:

• 60 degrees
• 180 degrees
• Less than 45 degrees
• Between 60 and 90 degrees

To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?

• 3
• 1
• 2
• 5

Special Circumstances: Securing a Cubic-Shaped Boulder

The securement of a cubic-shaped boulder must meet these requirements in addition to the other large boulder requirements in Section 13.

Secure each boulder individually with at least two chain tiedowns placed side-to-side across the vehicle.

Place tiedowns as closely as possible to the hardwood blocking used to support the boulder.

When securing paper rolls with friction mats as a primary method:

• All of these answers.
• The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
• The friction mat should stick out from underneath the roll in the direction it is providing securement.
• Make sure friction mats are completely covered by the roll.

Requirements for friction mats

If a friction mat is used to provide the principal securement for a paper roll, insert the friction mat so that it sticks out from beneath the footprint of the roll in the direction in which it is providing securement.
