There are some people who are not familiar with the Hazchem, but this is a type of system warning plate that is used for some vehicles that will be transporting materials and substances that can only be considered as hazardous. This type of plate can also be used when there are some storage facilities that are available. The hazard identification number is easily recognizable because this is usually in orange, and it can be placed on various vehicles that would also be transporting different materials that may not exactly be healthy for living things to be exposed to. This type of code is expected to be followed internationally so that it will remain the same for a long time to be used in different countries.
