These levels are basically 4 categories of biological agent which is transported from one place to another and potentially dangerous. The level 1 is having the minimum threat while the level 4 is having the maximum risk involved. When these biohazard symbols appear on something it might be from level 1 to level 4 as defined by UN. It is worth noting that the maximum risk which in involved in handling the level 4 of the biohazard is those infection and diseases which are fatal and no treatment is available for such disease. For example dengue fever, Marburg virus, and Lassa fever etc.
