Show answer & explanationAnswer & explanation
Correct answer: B. The words 'POISON-INHALATION HAZARD' or 'POISONOUS-INHALATION HAZARD' adjacent to the identification number.
For bulk packagings containing a material that is a PIH, the words 'POISON-INHALATION HAZARD' or 'POISONOUS-INHALATION HAZARD' must be displayed adjacent to the identification number. This provides crucial information about the specific danger.
Why the other options are wrong
- A. While a 'POISON' placard might be required for some PIH materials, the specific wording for bulk packagings is different and more direct for the PIH hazard.
- C. Labels are for non-bulk packages, and a 'TOXIC GAS' label is not the specific wording required for PIH bulk marking.
- D. This is too general and does not specifically address the PIH hazard as required for bulk packagings.
Bulk PIH Marking
Bulk packagings containing Poison Inhalation Hazard materials require specific wording adjacent to the identification number to highlight the PIH danger.
- Applies to bulk packaging only.
- Wording must be 'POISON-INHALATION HAZARD' or 'POISONOUS-INHALATION HAZARD'.
- Must be adjacent to the identification number.
Memory trick: Poison's Inhalation Hazard, next to the ID, is how bulk PIH is identified.
