Quiz difference between PG I PG II and placards?
Packing groups (PG I, II, III) and placards are two different things. Packing groups rate the degree of danger within a hazard class: PG I is great danger, PG II is medium, PG III is minor. Placards show the hazard class and division, not the packing group, so PG usually does not appear on the placard itself.
What packing groups are
Within a hazard class, the packing group ranks how dangerous a material is: PG I is the greatest danger, PG II is medium, and PG III is the least. It affects packaging and handling requirements, and it appears on shipping papers, not as the main feature of the placard.
What placards show instead
A placard tells you the hazard class and division (the color, symbol, and class number), so it answers what kind of hazard it is. The packing group answers how severe it is within that class. They work together but are not the same label.
Why this matters for the test
A question may try to blur the two. Remember: PG I, II, III is a danger level; the placard is the hazard class. Confirm exactly how your state tests this in your official manual.
