Hazmat
A tanker on its side with a placard on the back is a question you answer before you get any closer. The hazmat entries on the Protocols page turn that placard into instructions.
Searching
Search by UN number, by name, or by class — whichever you can read from where you are standing. The Hazmat chip hides the protocols, so only substances are left. A four-digit number off a placard is usually the fastest and the most reliable, because names get misread and numbers do not.
What you get
| ERG Guide | the emergency response guide number for the substance |
| Placard | what the marking should look like |
| Hazard | what it does — fire, corrosive, toxic, reactive |
| Emergency Action | what to do about it |
Using it
Look it up before you commit to an approach, not after. The whole value of the panel is in the ninety seconds between arriving and deciding where to park.
Read the emergency action out to command rather than paraphrasing it. Isolation distances and incompatible agents are exactly the details that get lost when somebody summarises.
What it is not
It is a reference, not a decision. It does not know your wind direction, what else is in the trailer, or how many people are downwind. It tells you what the substance does; the response is still yours and your community's.
And it records nothing — nothing you search here appears in a log. What you found and what you did with it belongs in the incident log and the report.
