Jet fuel is a petroleum fuel, so it is a Class 3 liquid on a red placard with a flame and a 3. Depending on the specific fuel and its flash point, the placard reads FLAMMABLE or COMBUSTIBLE, and it often shows a four-digit identification number. The red Class 3 diamond is the key; the wording follows the flash point.
Jet fuel is a Class 3 liquid
Jet fuel is a refined petroleum product, in the same Class 3 family as gasoline and diesel. That means a red placard with a flame symbol and the number 3. The red color and flame tell you it is a flammable or combustible liquid; the 3 fixes the class.
Flammable or combustible wording
Whether the placard reads FLAMMABLE or COMBUSTIBLE depends on the specific jet fuel and its flash point. Like other petroleum fuels, a lower flash point points to FLAMMABLE and a higher one to COMBUSTIBLE, but both are Class 3 and both use the red diamond. The wording is a detail under the same color and class.
What a jet fuel placard shows
The cues to recognize:
| Element | Jet fuel (Class 3) |
|---|---|
| Color | Red |
| Symbol | Flame |
| Class number | 3 |
| Word | FLAMMABLE or COMBUSTIBLE (by flash point) |
| ID number | Often a four-digit number shown |
Red Class 3 with a flame; wording follows the flash point. Confirm with the shipping papers.
Why the ID number matters
Fuel loads often display a four-digit identification number, sometimes on an orange panel or in the center of the placard, to identify the specific product so responders can look it up in the Emergency Response Guidebook. So a jet fuel load can show a red flammable placard plus that number, which together say flammable liquid, specifically this fuel.
How to study and verify
For recognition, treat jet fuel as Class 3: red, flame, 3, with FLAMMABLE or COMBUSTIBLE wording and often an ID number. Pair it with gasoline and diesel in your study as the petroleum-fuel group. Because the exact classification and number depend on the specific fuel, confirm them with the shipping papers, the Emergency Response Guidebook, and your official manual.
Frequently asked questions
- What placard does jet fuel use?
- Jet fuel is a Class 3 petroleum liquid: a red placard with a flame and a 3, reading FLAMMABLE or COMBUSTIBLE depending on the fuel's flash point, often with a four-digit ID number. Confirm with the shipping papers.
- Is jet fuel flammable or combustible?
- It depends on the specific fuel and its flash point. Both are Class 3 and red; a lower flash point reads FLAMMABLE and a higher one COMBUSTIBLE. Verify the classification for the specific product.
- Why does a fuel placard show a number?
- The four-digit identification number names the specific product so responders can look it up in the Emergency Response Guidebook. The red color and flame still show the Class 3 hazard.
