If a placard is visible but no product name, hazard class number, or four-digit UN number is given, how can you determine which ERG guide page to use?

If a placard is visible but no product name, hazard class number, or four-digit UN number is given, how can you determine which ERG guide page to use?

• A. The table of placards lists guide numbers.
• B. The color of the placard indicates the guide page.
• C. The UN identification code page provides the guide page.
• D. The emergency contact numbers inside the vehicle indicate the guide page.

Answer: (A)

When you don’t have a product name, hazard class number, or four-digit UN number on the placard, you determine the ERG guide page by using the placard-to-guide-number table. This table is designed to map each placard symbol or hazard category to a specific guide number. By identifying the placard’s symbol or basic hazard cue (what the placard communicates at a glance) and then finding the corresponding guide number in that table, you can immediately locate the correct ERG page to consult for initial safety actions. Colors of the placard aren’t a reliable way to pick a specific ERG page, and the UN identification code page only helps if a four-digit UN number is present. Emergency contact numbers inside the vehicle aren’t used to determine the ERG page either. The key is linking the visible placard to its guide number through the dedicated table.
