- Raw: All tree species that have been harvested with bark; may have been trimmed or cut to length
- Partially processed: Fully or partially debarked, or further reduced in length
- Fully processed: Utility poles, treated poles, log cabin building components
The specific requirements for logs cover short wood and long wood.
Short Wood
- Normally up to about 2.5 m (100 in) in length.
- No longer than 4.9 m (16 ft) in length.
-
Also called:
- Cut-up logs
- Cut-to-length logs
- Bolts
- Pulp wood
Long Wood
- Anything not considered short wood.
- Also called Long Logs or Tree-length.
Exceptions to the specific requirements
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.]
What's in a stack?
Some stacks may consist of both short wood and long wood. Any stack that includes short wood must follow the short wood securement requirements.
Exception: If short wood is embedded in load of long wood, it can be treated as long wood.
Components of the Securement System
Specially designed vehicle
Requirements:
- Vehicle must be designed and built, or adapted, for transportation of logs.
- Vehicle must be fitted with a means to cradle the logs and prevent rolling, such as:
- Bunks
- Bolsters
- Stakes. OR
- Standards
- All vehicle components must be designed and built to withstand all expected operational forces without failure, accidental release, or permanent deformation.
Stakes
Requirement:
If stakes or standards are not permanently attached to the vehicle, secure the stakes so that they do not separate from the vehicle.
Tiedowns
Requirements
- Use tiedowns in combination with bunks, stakes, or standards and bolsters to secure the load.
- All tiedowns must have a working load limit not less than 1,800 kg (4,000 lb.).
- Tension tiedowns as tightly as possible but not beyond their working load limit.

-
Bulkhead:
A vertical barrier across a vehicle to prevent forward movement of cargo.

Hook-lift Container:
A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
-

The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Multiple-Choice Questions:
In what circumstance can shortwood be treated as longwood?
- When it is embedded in a stack of longwood.
