A driver is transporting packages of Class 5.2 (Organic Peroxides) and Class 3 (Flammable Liquids). According to the segregation requirements, how must these materials be loaded?
- AThey may be loaded together without segregation if both are in non-bulk packaging.
- BThey can be loaded together if separated by a non-hazardous material of at least 24 inches.
- CThey must be separated by at least one intervening package space or by a distance of 24 inches when loaded in the same vehicle.
- DThey must be loaded into separate transport vehicles.
Show answer & explanationAnswer & explanation
Correct answer: C. They must be separated by at least one intervening package space or by a distance of 24 inches when loaded in the same vehicle.
Organic Peroxides (Class 5.2) and Flammable Liquids (Class 3) are incompatible. The segregation table (49 CFR 177.848) indicates they must be separated by at least one intervening package space or a distance of 24 inches when loaded in the same transport vehicle. They are not strictly forbidden from being on the same vehicle, but require physical separation.
Why the other options are wrong
- A. Packaging type does not negate the need for segregation between incompatible classes.
- B. A non-hazardous material separation is not specified; the requirement is for a package space or distance.
- D. While separating into different vehicles is always safer, regulations allow them on the same vehicle with proper segregation, so this is not the *only* option.
Segregation: Organic Peroxides & Flammable Liquids
The requirement to physically separate Class 5.2 (Organic Peroxides) and Class 3 (Flammable Liquids) by at least one intervening package space or 24 inches when transported in the same vehicle.
- Both are fire hazards, but Organic Peroxides are highly reactive.
- Separation prevents intensification of a fire or reaction.
- Not forbidden on the same vehicle, but require strict separation.
Memory trick: Peroxide, fluid, give them space, for safety's sake, in any case.
