When transporting a $7\text{-foot}$ -long, $10,400\text{-pound}$ cylindrical pressure vessel that is not blocked against a bulkhead, securing it with a single indirect strap rated at a Working Load Limit (WLL) of $5,500\text{ pounds}$ complies with federal cargo securement regulations.

Cevap: Cevap

Cevap

False

The statement is false because federal commercial vehicle regulations require cargo securement to satisfy two separate standards: aggregate Working Load Limit (WLL) of at least 50% of cargo weight and minimum tie-down count. For an unblocked article exceeding 5 feet in length (or weighing over 1,100 pounds), at least two tie-downs are mandatory.

Adım Adım Çözüm

Calculate the required aggregate Working Load Limit (WLL) for the cargo.

The minimum aggregate WLL required is

50\%

10,400\text{ pounds} = 5,200\text{ pounds}

. The single strap with a WLL of

5,500\text{ pounds}

satisfies this weight threshold.

Federal regulations require that the aggregate WLL of all tie-downs securing an article must equal at least one-half of the cargo's total weight.

Determine the minimum tie-down count required by cargo length and blocking status.

For unblocked cargo measuring between

5\text{ and }8\text{ feet}

in length (or weighing more than

1,100\text{ pounds}

), a minimum of two tie-downs is legally mandated.

Drivers must satisfy independent dimensional securement rules in addition to weight-based strength requirements.

Assess overall regulatory compliance.

Because only one tie-down is used, the securement configuration violates the minimum tie-down count standard, making the shipment non-compliant.

Both aggregate WLL and minimum tie-down count criteria must be concurrently satisfied for a load to be legal and safe.
