Match each commercial motor vehicle operational condition or equipment category on the left with its corresponding mandatory emergency equipment specification on the right.
- Power unit hauling general freight (non-hazardous cargo)Properly rated and charged fire extinguisher with a minimum Underwriters Laboratories (UL) rating of 5 B:C
- Power unit transporting placarded hazardous materialsProperly rated and charged dry chemical fire extinguisher with a minimum Underwriters Laboratories (UL) rating of 10 B:C
- Vehicle electrical circuits using replaceable fusesAt least one spare fuse for each specific type and amperage rating required to operate any vehicle system
- Standard roadside emergency warning systemThree bidirectional red reflective triangles stored securely in the vehicle
Cevap
General freight matches 5 B:C extinguisher rating; Hazardous materials transport matches 10 B:C extinguisher rating; Fused circuits match spare fuses of each type and size; Roadside emergency warning matches three bidirectional red reflective triangles.
Each operational condition directly corresponds to specific emergency safety regulations: standard non-hazardous cargo power units require at least a 5 B:C fire extinguisher; placarded hazardous materials vehicles require at least a 10 B:C fire extinguisher; vehicles with replaceable fuses must carry spare fuses for every size and type needed; and all commercial motor vehicles must be equipped with three bidirectional red reflective triangles for roadside breakdowns.
