"Fully contained" means that the cargo is placed against a vehicle structure of adequate strength or other cargo so that it cannot shift or tip. Cargo that fills a sided vehicle of adequate strength is considered fully contained.
What is a reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.?

The manufacturer’s working load limit is reduced by 50% for tiedowns which are directly attached from the vehicle to the article, and tiedowns attached to the vehicle that go around, through or over the article and are reattached to the same side of the vehicle.

Performance Criteria for Securement Systems:
Part I: Cargo Securement Performance Criteria
The standard provides the minimum amount of force that cargo should be expected to withstand, in each direction, as shown below.
These minimum force requirements, called the â€śperformance criteriaâ€ť, were determined after extensive testing. The securement system MUST be capable of resisting these forces, as shown below.
The forward force (80% of the cargo weight) represents braking while driving straight ahead.
The rearward force (50% of the cargo weight) represents vehicle acceleration or braking in reverse.
The side-to-side or lateral force (50% of the cargo weight) represents traveling on a curve, ramp or changing lanes.
The vertical force (20% of the cargo weight)) represents cargo vibration during transport. This requirement is satisfied when the cargo is "Fully Contained"
The performance criteria may also be expressed in terms of acceleration, which is shown at right (â€śgâ€ť is the term used for gravity, and represents acceleration or deceleration).
0.8 g deceleration in the forward direction.
0.5 g deceleration in the rearward direction.
0.5 g acceleration in a side-to-side or lateral direction.
0.2 g vertical acceleration.
EXAMPLE: If a steel coil weighs 10,000 lbs., the load securement must provide 8,000 lbs. of securement to prevent movement in the forward direction, which is expressed as 80% of the cargo weight (or 0.8 g).
PART II - Performance Criteria for Components of a Securement System
Each component of the cargo securement system should not exceed its Working Load Limit (WLL), when at maximum force. The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service; it is usually assigned by the manufacturer of the component.
Each force in the performance criteria is to be applied separately to the securement system to determine if it is compliant.
Cargo Securement Terms That Truck Drivers Should Know:
Working Load Limit (WLL):
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 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.
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
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).
Vehicle Structure and Anchor Points
The vehicle must be strong enough to resist the forces in the performance criteria (Section 1). The vehicle must be appropriate for the cargo it is to transport, or it must be adapted to be suitable by using fittings, fixtures, dunnage, cribbing or other means.
Cargo Securement Responsibility
According to federal and state regulations, the carrier and driver are responsible for ensuring that the vehicles, anchor points and other securement components are in good working order, with no obvious signs of damage. The driver is also required to conduct a pre-trip inspection by other operating regulations.
Roadside inspections are conducted in accordance with federal, state and provincial laws. If securement equipment fails inspection, it is likely that the vehicle may be placed out-of-service, and the motor carrier and/or the driver may be fined.
