In the same manner as the Class 1, the Class 2 as well has its own sub-classifications.
| Division 2.1 | Flammable gases- example of flammable gases are hydrogen, methane, acetylene. |
| Division 2.2 | Non-flammable, non-toxic gases- nitrogen, compressed air, helium, argon. |
| Division 2.3 | Toxic gases- carbon monoxide, chlorine, phosgene. |
Thereupon, these dangerous goods are extremely hazardous if the gases are exposed at 50 degrees has a vapor pressure greater than 300kPa. Also, it is good for you to know that the gasses can be stored as well compressed liquefied or under pressure.
Class 3: Flammable Liquids
So, we’ve came to Class 3. This class includes the flammable liquids. Flammable liquids are dangerous goods as well, because are capable of being burned or ignited. That is to say the ignition of the flammable liquid is seen as the biggest hazard.
