Frequently asked questions

What is Placardset?

A practice tool for hazmat awareness trainees and their instructors. A scenario shows a placard, an orange panel or a shipping paper line; you name the class, find the guide number, read the distance and pick the first actions, and each step is graded with the page it comes from.

Is it free?

Yes. Everything on the site is free, with no account.

Where does the data come from?

From the 2024 Emergency Response Guidebook (ERG2024), typed in from the public English PDF on 2026-09-27: the whole yellow index (2,771 rows), every guide's immediate precautionary distance, the placard table, and the 41 Table 1 rows on printed pages 290 and 291. Hazard classes come from the Hazardous Materials Table, 49 CFR 172.101. The guidebook may be reproduced without further permission; no government name or seal is used as an endorsement.

How do I know a number is right?

Every row keeps its printed page, and a test compares the yellow index with the blue index row for row, the Table 1 rows with the book's own text layer, and each guide's distance with its printed line. If you find a number that disagrees with the printed guidebook, the printed book wins; please tell us and it gets fixed.

Can I use this during a real incident?

No. It is a training aid. In a real incident follow the current printed guidebook and your employer's emergency plan.

What is in the drill set?

68 materials across every class except explosives, plus 8 placard only scenarios (the explosives divisions, radioactive and DANGEROUS) that are worked from the placard table. Every highlighted material in the drill set has its Table 1 row on the page, so the distance is always there to read.

Why does the drill show the table instead of making me remember it?

Because the skill is the lookup, not memory. Awareness training asks you to find the right page and read the right column fast and without mistakes, which is what the drill grades.

Is my data uploaded?

No. Any name you type, for a certificate or a class, stays in this browser. Nothing is uploaded. Progress lives in this browser; export it as a JSON or CSV file to keep a copy.

Can an instructor use it with a class?

Yes. Projection mode puts one scenario on the classroom screen with four questions, reveals the answers on the instructor's cue, and prints an answer key with a class name.

Is it a qualification?

Placardset is a training aid; in a real incident follow the current printed guidebook and your employer's plan. The certificate of practice records practice, not training required by any regulation.

Who runs Placardset?

An independent site. Placardset is not affiliated with, endorsed by or produced by any government, transport agency, regulator, fire service or training body.
