What does the term "chocking" refer to in PBCFR SOGs regarding vehicle operations?

The term "chocking" in PBCFR SOGs regarding vehicle operations specifically refers to the practice of placing wheel chocks to prevent a vehicle from moving during loading or unloading. This is an important safety measure that ensures the vehicle remains stable and secure, especially when personnel are entering or exiting the vehicle or handling equipment. By using wheel chocks, drivers and crew members can significantly reduce the risk of accidents caused by unexpected movements of the vehicle, thereby promoting a safer work environment.

The other options address various vehicle operations but do not align with the definition of "chocking." For instance, cutting off engine power to save fuel might be a consideration for fuel efficiency but lacks relevance to maintaining safety during loading or unloading. Aligning the vehicle with the loading dock is important for efficiency but is not related to stabilizing vehicle movement. Adjusting tire pressure is a maintenance measure that affects vehicle performance but does not pertain to the specific practice of chocking. Each of these options serves its purpose, but only the practice of placing wheel chocks directly relates to the term "chocking."
