Difficulty: MediumEmergency Equipment Requirements

A carrier is outfitting a new tractor-trailer for general dry freight operations across state lines. Under standard safety regulations, which combination of emergency safety equipment must be onboard before the vehicle is dispatched?

  1. A
    One 10 B:C fire extinguisher, two bidirectional reflective triangles, and a set of replacement headlamp bulbs
  2. One properly charged 5 B:C fire extinguisher, three bidirectional reflective triangles, and spare electrical fuses for each required circuit typeAnswer
  3. C
    Two 2 B:C fire extinguishers, four orange traffic cones, and an auxiliary battery jumper pack
  4. D
    One 5 B:C fire extinguisher, two red burning fusees, and spare electrical fuses regardless of whether the vehicle uses automatic circuit breakers

Answer

One properly charged 5 B:C fire extinguisher, three bidirectional reflective triangles, and spare electrical fuses for each required circuit type
For a commercial motor vehicle transporting non-hazardous general freight, the three mandatory emergency items are: a securely mounted, fully charged fire extinguisher with a minimum rating of 5 B:C; three bidirectional red reflective triangles; and at least one spare electrical fuse of each required size/type (unless the vehicle utilizes circuit breakers).

Step-by-Step Solution

1
Identify the minimum fire extinguisher requirements for non-hazardous cargo
Requires at least one 5 B:C rated (or two 4 B:C rated) fire extinguisher that is fully charged, securely mounted, and readily accessible.
Commercial motor vehicles hauling non-hazardous general freight must meet the baseline 5 B:C Underwriters' Laboratories rating.
2
Verify required emergency warning devices for stopped vehicles
Requires three bidirectional red reflective triangles (or at least six fusees / three liquid burning flares where permitted).
Three reflective triangles provide adequate warning distances ahead, behind, and beside a disabled commercial vehicle.
3
Check spare electrical component requirements
Requires at least one spare fuse for each type and size needed to operate any required part or accessory, unless equipped with circuit breakers.
Having spare fuses ensures essential electrical lighting and safety circuits can be promptly restored on the road.

Key Concept

Three mandatory items of emergency equipment: properly rated fire extinguisher, warning devices, and spare fuses.
