However, DOT does allow hazardous materials of the same class to be stowed together without regard to segregation required for any secondary hazard if the materials are not capable of reacting dangerously with each other and causing combustion or dangerous evolution of heat, evolution of flammable, poisonous, or asphyxiant gases, or formation of corrosive or unstable materials.
Incompatible dangerous goods should not be transported or stored together to avoid possible reactions between the dangerous goods or reduce the hazards of any accidental leakage or spillage. For incompatible materials, shared transportation or storage may still be allowed if the materials are separated from each other by a minimum distance. In this article, we will share with you dangerous goods segregation table, the general principles of segregation, and how to get necessary information to determine whether you should transport or store a hazardous material together with other hazardous materials.
(X): These materials may not be loaded, transported, or stored together in the same transport vehicle or storage facility during the course of transportation. Both main hazard risks and subsidary risks need to be taken into account. If you do know what those hazard classes and subsidary risks mean, please click here.
(O): These materials may not be loaded, transported, or stored together in the same transport vehicle or storage facility during the course of transportation unless separated from each other (Usually >=3 meters). However, Class 8 (corrosive)liquids may not be loaded above or adjacent to Class 4 (flammable) or Class 5 (oxidizing) materials except that the mixture of contents would not cause a fire or a dangerous evolution of heat or gas;
(*) Segregation among different Class 1 (explosive) materials is governed by the compatibility table. Exception: ammonium nitrate (UN 1942) and ammonium nitrate fertilizer may be loaded or stored with Division 1.1 (Class A explosive) or Division 1.5 (blasting agents) materials.
To determine whether you should transport or store a hazardous material together with other hazardous materials, you need to have access to the safety data sheets of the hazardous materials. The following 3 sections of safety data sheets are particularly important.
This Technical Measures Document refers to issues surrounding the storing and segregation of hazardous materials and how it can be used to minimise the foreseeable risks of a major accident or hazard.
