DOT / UN Shipping Classification of explosives and other hazardous materials
Safe transport of explosives within the United States requires Competent Authority Approval by an authorized agency. Safety Consulting Engineers is one of only six bodies recognized by the U.S. Department of Transportation (DOT) to Test and Examine explosives or potentially explosive substances, and provide proper shipping Hazard Classification Recommendation for a company’s EX # application to DOT.
We have the appropriate accreditations, expertise, and full testing equipment and facilities to assist you with the testing and analysis of your hazardous materials and processes.
The required tests vary depending on factors such as the classification sought, the material type, and the initial test results. While some manufacturers can self-classify their products, provided they have the ability to properly perform the requisite tests and analysis, this is not the case with explosives and certain energetic materials. Companies must use a DOT-approved laboratory, such as Safety Consulting Engineers, which will provide an authorized DOT Examiner to witness these tests. U.S. military and DOD facilities must have the concurrence of the Joint Classifiers for the armed services.
Entities such as the US military, U.S. Department of Transportation (DOT), and the United Nations (UN) have participated in the development of a common classification system consisting of nine (9) classes and a varying number of divisions within those classes. The nine classes with their divisions, as used by the U.S. DOT are:
|Class Number||Division||Name of Class or Division|
|1||1.1||Explosives (with a mass explosion hazard)|
|1||1.2||Explosives (with a projection hazard)|
|1||1.3||Explosives (with predominately a fire hazard)|
|1||1.4||Explosives (with no significant blast hazard)|
|1||1.5||Very insensitive explosives; blasting agents|
|1||1.6||Extremely insensitive detonating substances|
|2||2.2||Non-flammable compressed gas|
|3||-||Flammable and combustible liquid|
|4||4.2||Spontaneously combustible material|
|4||4.3||Dangerous when wet material|
|6||6.2||Infectious substances (etiologic agent)|
|9||-||Miscellaneous hazardous material|
|None||-||Other regulated material: ORM-D|
DOT classification is required for materials in transport, and are often used for materials in storage. Those shipping hazardous materials have a legal obligation to know the hazards of the material and to verify the proper shipping classification.
