Diesel for tour lighting generators is a Class 3 liquid on a red placard, and because of its higher flash point it usually reads COMBUSTIBLE rather than FLAMMABLE. It commonly shows a four-digit identification number on an orange panel. Whether a generator-fuel load must be placarded depends on the quantity, so confirm for your specific load.
Diesel is a Class 3 liquid
Diesel, the fuel for tour lighting and power generators, is a Class 3 liquid on a red placard with a flame and a 3. Class 3 covers flammable and combustible liquids, and diesel sits in that family, so the red diamond is the recognition cue.
Usually COMBUSTIBLE, not FLAMMABLE
Because diesel has a relatively high flash point, it usually qualifies as a combustible liquid rather than a flammable one, so the placard typically reads COMBUSTIBLE. Gasoline, with a much lower flash point, is the FLAMMABLE counterpart. Both are red Class 3; the wording and flash point are what differ.
Diesel placard at a glance
The cues to recognize:
| Item | Diesel |
|---|---|
| Hazard class | Class 3 |
| Color | Red |
| Word | Usually COMBUSTIBLE |
| Flash point | Higher than gasoline |
| ID number | Often shown on an orange panel |
Diesel is a red Class 3, usually COMBUSTIBLE. Verify the quantity rule in the regulations.
Whether the load is placarded
A tour carrying generator diesel may or may not need a placard depending on the quantity. Placarding for most materials is triggered by amount, so a small fuel supply can fall below the threshold while a larger one requires the Class 3 placard. So the question turns on how much diesel is aboard, not just that it is diesel.
How to study and verify
Recognize diesel as a red Class 3 liquid that usually reads COMBUSTIBLE, often with an identification number, and pair it with gasoline (FLAMMABLE) to keep the wording straight. Whether a specific generator-fuel load requires placarding depends on the quantity, so confirm the threshold for your load with the shipping information and the current regulations.
Frequently asked questions
- What placard does generator diesel use?
- Diesel is a Class 3 liquid on a red placard, usually reading COMBUSTIBLE because of its higher flash point, often with an identification number. Whether a load is placarded depends on the quantity. Verify the quantity rule in the regulations.
- Is diesel flammable or combustible?
- Usually combustible. Diesel's higher flash point makes it a combustible liquid (red Class 3, reading COMBUSTIBLE), while gasoline's lower flash point makes it flammable. Both are Class 3 and red.
- Does a tour's generator fuel need a placard?
- It depends on the quantity. Placarding is triggered by amount, so a small fuel supply may fall below the threshold while a larger one requires the Class 3 placard. Confirm for your specific load.
