A driver is transporting a shipment of UN1814, Potassium hydroxide solution, Class 8, PG II, in an Intermediate Bulk Container (IBC). The IBC has a capacity of 1,500 liters. Which of the following markings is specifically required on this IBC, in addition to the proper shipping name and identification number?
- AThe UN packaging symbol and code.
- BThe name and address of the consignee.
- CA 'CORROSIVE' label.
- DA 'DANGEROUS' placard.
Show answer & explanationAnswer & explanation
Correct answer: A. The UN packaging symbol and code.
IBCs, as bulk packagings, require specific UN packaging symbols and codes (e.g., 31A, 31H1) to indicate their design type and material, in addition to typical hazard communication like proper shipping name and identification number. Labels are generally for non-bulk packages.
Why the other options are wrong
- B. The consignee's name and address are typically on shipping papers, not a required marking on the IBC itself.
- C. While a 'CORROSIVE' placard would be required on the vehicle, an IBC itself would not typically have a 'label' (which is for non-bulk packages) but rather specific markings for its design and UN number.
- D. A 'DANGEROUS' placard is a general placard and not a specific marking for an IBC's construction or type.
IBC Specific Markings
Intermediate Bulk Containers (IBCs) require specific UN packaging symbols and codes to indicate their design type and material, beyond standard hazard communication.
- Applies to IBCs as bulk packagings.
- UN packaging symbol and code (e.g., 31H1 for composite IBC) is required.
- Indicates design type, material, and performance standards.
- Different from labels (for non-bulk) or general placards.
Memory trick: IBCs show their UN code, telling their design and their load.
