Which dangerous cargo sign is division 2.1 in dot manuals 2026 updates generator drill of…?
Division 2.1 is flammable gas, and its placard is a red diamond with a flame symbol and a 2 at the bottom. Red is the flammable color, and the 2 tells you it is a gas, so a red diamond with a flame and a 2 is the flammable-gas sign.
Red flame with a 2 means flammable gas
Division 2.1 flammable gases use a red placard with a flame symbol and a 2. The red color signals flammable, and the class number 2 signals gas, so together they mean flammable gas (think propane and similar).
How it sits among the gas divisions
Class 2 has three divisions: 2.1 flammable gas (red), 2.2 non-flammable gas (green), and 2.3 toxic gas (white with a skull). Reading the color plus the symbol places any gas placard correctly.
