Transportation Research Board Publishes Test Method Developed by Alliance Technologies
(Nov. 21, 2014) Water-reactive substances that release flammable gases when in contact with water are assigned to USDOT Hazard Class 4.3. However, the released gases may also be highly toxic, and the current test method is inadequate for classifying these chemicals. Alliance Technologies and ScienceSmith Consulting created the initial revision to the HM-14 test standards published by the Transportation Research Board’s Hazardous Materials Cooperative Research Program in Report 13: Test Procedures and Classification Criteria for Release of Toxic Gases from Water-Reactive Materials. This new revision improves the procedure for measuring the rate of gas production when a water-reactive material evolving either a flammable gas or a toxic gas is combined with water.
