- AThe technical name(s) of the hazardous component(s) in parentheses.
- BThe gross weight of the portable tank in pounds.
- CThe emergency response telephone number.
- DThe word 'PORTABLE TANK' in 2-inch letters.
Show answer & explanationAnswer & explanation
Correct answer: A. The technical name(s) of the hazardous component(s) in parentheses.
When transporting hazardous materials described by an N.O.S. (Not Otherwise Specified) entry in a bulk packaging (like a portable tank), the technical name(s) of the hazardous component(s) that most contribute to the hazard must be displayed in parentheses immediately following the basic description on the shipping paper and on the packaging itself. This provides more specific information about the material.
Why the other options are wrong
- B. Gross weight is generally required for bulk packages, but not specifically due to an N.O.S. entry.
- C. Emergency response numbers are primarily on shipping papers, not directly on the bulk packaging as an N.O.S. specific marking.
- D. While bulk packages have size requirements, 'PORTABLE TANK' isn't a specific N.O.S. marking.
Bulk N.O.S. Marking (Technical Name)
For N.O.S. hazardous materials in bulk packagings, the technical name(s) of the hazardous components must be displayed on the packaging.
- Applies to N.O.S. entries in bulk packaging (e.g., portable tanks, cargo tanks).
- Technical name(s) must be in parentheses.
- Provides more specific identification than the N.O.S. entry alone.
Memory trick: N.O.S. means need more specifics, technical name's the key.
