CDL Hazardous Materials Endorsement (HME)Loading and Unloading Hazardous MaterialsHard

A driver is transporting packages of Class 5.2 (Organic Peroxides) and Class 3 (Flammable Liquids) in the same vehicle. According to the segregation requirements of Table 177.848(e), what is the minimum segregation requirement between these two classes?

  1. AThey must not be loaded together in the same transport vehicle.
  2. BThey must be separated by a minimum distance of 2 feet.
  3. CThey must be separated by a minimum distance of 1 foot.
  4. DNo segregation is required; they can be loaded together.
Show answer & explanation

Correct answer: A. They must not be loaded together in the same transport vehicle.

According to the segregation table (49 CFR 177.848(e)), Class 5.2 (Organic Peroxides) and Class 3 (Flammable Liquids) are incompatible and fall under a 'X' segregation requirement, meaning they must not be loaded, stored, or transported together in the same transport vehicle. They can react dangerously.

Why the other options are wrong

  • B. Distance-based segregation is not sufficient for these incompatible materials.
  • C. Distance-based segregation is not sufficient for these incompatible materials.
  • D. This is incorrect; these materials are incompatible and require segregation.

Organic Peroxides & Flammable Liquids Segregation

Class 5.2 (Organic Peroxides) and Class 3 (Flammable Liquids) are incompatible and must not be loaded or transported together in the same transport vehicle.

  • Incompatible due to dangerous reactions.
  • Segregation code 'X' in 49 CFR 177.848(e).
  • Prohibited from same vehicle transport.

Memory trick: Peroxide Flammable, Same Truck Unmanageable.
