Read an orange panel without confusing the two numbers

Label each part of the example

On the numbered ADR orange panel, the upper field is the hazard identification number and the lower field is the four-digit UN number. Placards provide additional hazard-class information. A blank orange marking should not be treated as an invitation to invent a missing number.

• Copy letters and digits as printed.
• Label the upper and lower fields separately.
• Record the placards shown in the example.
• Compare the complete example with the official reference.

Keep identification separate from response

The UN entry and a hazard category are reference inputs, not a complete description of conditions. A marking alone does not tell you the package's condition, the quantity released or every circumstance at a site. This is why a panel-reading exercise should end with the correct reference entry, not an improvised response plan.

Hazora makes UN/NA material lookup, placard reference and ADR-number decoding available on iPhone. The web decoder is narrower and supports only its explicit training examples. Do not approach an incident to obtain a better photograph or use this page to make a live emergency decision; communicate with the responsible emergency service and follow its directions.
