UN Hazards Classification

Assignment of EX Number:

Zukovich, Morhard & Wade, LLC has provided technical guidance for classifying more than forty-four (44) new explosives substances and articles. Proper transportation hazard classification for an explosive, of course, culminates with the assignment of an EX Number. Much more specific than a Hazard Classification, an EX Number applies to a particular explosive formula and its packaging. The EX number is required for MSHA, DOT, ATF and State and Local authorities.

Regulatory Requirement for Testing

The Regulatory Requirement for Testing requires that ‚€œnew explosives‚€Ě must be examined and approved before they can be transported in commerce. A ‚€œnew explosive‚€Ě means an explosive produced by a person who ‚€œ(1) Has not previously produced that explosive; or (2) Has previously produced that explosive but has made a change in the formulation, design or process so as to alter any of the properties of the explosive.‚€Ě

Each manufacturer must have its explosive or explosive device examined and approved. Each person requesting approval of a new explosive must submit a copy of a recommended hazard class issued by one of the approved laboratories cited and must receive written approval and an EX-number or Competent Authority Approval before offering that explosive for transportation and enabling the use for mine blasting.

A specific series of tests determines the hazard classification and form the basis for a report prepared by ZMW with recommendations for approval. Occasionally, ZMW can provide expert knowledge of the material can, in some cases, substitute for some of the tests in this process.

The classification document assigns an EX-number and provides the United Nations classification name, number, compatibility group, and serves as a competent authority approval needed when shipping under international regulations.

Competent Authority Approvals

Competent Authority Approvals are documents issued to comply with United Nations Guidelines, Governmental Organizations responsible for explosives use, Defense Organizations to comply with various regulations and guidelines, as well as the International Civil Aviation Organization Regulations and the International Maritime Dangerous Goods Code.

The documents can provide classification information only or provide stipulations on how to package, mark, test and/or a variety of other special provisions to follow when shipping domestically or internationally.

ZMW provided technical services to ATK Alliant TechSystems - Thiokol Technologies International, Inc. and the US Department of Defense Threat Reduction Agency (DTRA) to demilitarize the former Soviet SS-24 ICBM's in Pavlograd, Ukraine. The SS-24 propellant is being washed out from the rocket motor cases and combined with an emulsion matrix, packaged and recycled as industrial explosives in Ukraine. ZMW formulated a novel emulsion matrix compatible with the washed out SS-24 propellant, designed production equipment, and was a team member of the explosives safety and UN Hazards Classification program.
