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