Sensitivity Testing

Safety Management Services, Inc. (SMS) has extensive testing capabilities for characterization of explosives and hazardous materials. SMS personnel are intimately familiar with test methodologies, equipment, data acquisition, and data evaluation.

Our understanding of explosives and hazardous materials along with our testing expertise allows us to assist clients with determining what tests are appropriate, development of custom tests, interpretation of test results, and application of test results to the specific process or system. These testing services may be used independently or in conjunction with our process hazards analysis, incident investigation, facility siting, and other analysis services. Additionally, SMS offers training courses on the fundamental techniques used in explosives testing.

SMS testing capabilities include laboratory, bench-scale, sub-scale, and full-scale testing. This includes over 70 standard tests are available to characterize materials under conditions that simulate actual process conditions. Testing capabilities include both standard and custom testing tailored specifically to the client’s needs.

These standard tests include material sensitivity testing (e.g., impact, friction, ESD, electrical properties, chemical compatibility, etc.), DOT and DoD testing, and TNT equivalency testing. Our testing capabilities also include custom testing tailored specifically to the client’s requirements. Bench-scale and full-scale testing can be performed to better understand key operating parameters of processes and systems. Recommendations based on statistical evaluation of the material test data are made to help the client minimize process risks.

Below is a list of many of our test capabilities. A more in-depth review of various tests and methods can be found by clicking the links at the bottom of this page (some familiarity with explosives and related testing is assumed). For testing consideration, SMS must be provided with information needed to understand your material and the objective of the testing, as specified in “Standard Required Information for Testing.”

Director of Engineering and Testing
SMS is one of five laboratories authorized by the DOT to witness classification tests for explosives (Class I). We also frequently run in-process tests. Testing is performed at our test site facility at the Tooele Army Depot where we have a thermal lab, sensitivity test lab, and large scale test area. Please contact us for further information at 801-567-0456 or by sending a request.
