Flammable Liquids VS Flammable Solids
Most people, don't know the difference between class 4 and class 3 dangerous goods as they are both flammable substances. However, the storage and handling of these two flammable substances are different which means that they are required to be stored seperately from each other.
The reason that these two dangerous goods are made into a separate class of dangerous good is because of the different conditions required for ignition. While most people understand that heat is the main condition for a class 3 flammable liquid to ignite and become a hazard; it is vastly different in flammable solids because they have a few extra conditions which can cause ignition and combustion which are:
- Exposure to air
- Exposure to water
- Insufficiently diluted
These conditions are only applicable based on the flammable solid's different categories.
Safely Storing Flammable Solids

If you Store these flammable solids in the wrong conditions, it can become a hazard to the environment and people around it because each type of flammable solids have their own conditions of storing and usually can't be stored in the same area as Class 3 flammable Liquids or other Flammable Solids.
