• If load is 5ft or shorter, 1,100 lbs or lighter:

  Minimum number of tiedowns: 1

• If load is 5ft or shorter, over 1,100 lbs:

  Minimum number of tiedowns: 2

• If load is more than 5ft but less than 10ft:

  Minimum number of tiedowns: 2

Note: More tiedowns may be required to satisfy the general cargo securement requirements. The Standard states: "The sum of the working load limits from all tiedowns must be at least 50% of the weight of the cargo."

Edge protector:

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.

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.

The following types of logs are not covered by the specific logs requirements:

• Logs unitized by banding or other comparable means. [Secure according to general cargo securement requirements.]
• Loads of no more than four processed logs. [Secure according to general cargo securement requirements.]
• Firewood, stumps, debris, other short logs, and longer logs. [Transport in a vehicle or container enclosed on both sides, the front, and the rear and strong enough to contain them.]

Blocking must be:

• Placed against the pipe
• Secured to prevent it from moving out from under the pipe.

Timber blocking must have a minimum nominal dimension of 10 x 15 cm (4 x 6 in).

General tiedown requirements

The aggregate working load limit of all tiedowns on any group of pipe must be more than half the total weight of all pipes in the group.

One tiedown

A stack can be secured with one tiedown if all logs in the stack less than 3.04 m (10 ft) are:

• Blocked in the front by a headboard strong enough to restrain the load or by another stack of logs.
• Blocked in the rear by the vehicle's end structure or another stack of logs.

Immobilize the front and rear pipe with on of the following methods:

• Blocking
• Wedges
• Vehicle end structure
• Stakes
• Locked pipe unloader
• Other equivalent means

Requirements for eyes crosswise: secure stacks of paper rolls from front-to-back movement

• Do not load paper rolls on a second layer unless the bottom layer extends to the front of the vehicle.
• Load paper rolls on higher layers only if all wells in the layer beneath are filled.
• Secure the foremost roll in each upper layer (or any roll with an empty well in front of it) against forward movement:
  • Either by placing it in a well formed by two rolls on the lower row whose diameter is equal to or greater than that of the roll on the upper row.
  • Or by banding it to other rolls.
  • Or by blocking it against an eye-vertical blocking roll resting on the floor of the vehicle that is at least 1.5 times taller than the diameter of the roll being blocked.
