Download or read book Proposed New Procedure for Estimating Allowable Number of Rounds for Blast Overpressure Hazard Assessment written by James H. Patterson and published by . This book was released on 1997 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current procedures for health hazard assessment of weapons blast overpressure use criteria contained in MIL-STD-1474D These criteria are applied to the test data so that the single pressure-time signature which indicates the greatest hazard (worst case round) is used to derive the recommended firing restrictions for the system. This approach is conservative and probably overrestricts the use of the system. Since it is based on the worst case round, the rest of the test data are essentially ignored in the hazard assessment. A procedure to establish recommended firing limits using all of the data has been developed. The procedure is based on accumulating hazards over the test data set until the criterion value is reached. This establishes the allowable number of rounds. A maximum exposure level for the worst case round is retained to prevent injury from single round exposures. Two variations of the basic procedure are explored and numerical examples of each are presented. The procedure implemented using a proportional dose accumulation is recommended.

This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A soldier in training is exposed to a variety of blast sources that can adversely affect his auditory and nonauditory systems. While auditory standards have been formulated for many decades, knowledge about nonauditory effects of blast have not been captured in a criteria that can be applied to all circumstances. For the past 15 years, JAYCOR, working together with the Walter Reed Army Institute of Research, has been using modeling, simulation, and data analysis to determine the nature of injury in animal models, capture that understanding in physiologically correct mathematical models, and extend the findings to objective criteria that can be used to set exposure limits. This paper summarizes the accomplishments of that effort.

Download or read book Health Hazards Assessment for Blast Overpressure Exposures written by and published by . This book was released on 1994 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army needs to set blast overpressure exposure standards that will protect soldiers in training against adverse effects from blast coming from a variety of weapons in a variety of surroundings. JAYCOR is developing biomechanical models that compute the tissues level response due to external blast loading and correlations of that response to pathology and lethality. To validate the models, animal test data has been organized into a database. Trends in the data have been determined that are independent of the models and agreement between the correlations and observations have been good for all level of blasts and animal species. The future work will refine the pathology prediction by location and provide a probabilistically-based methodology for making health hazards assessment.

Available in PDF, EPUB and Kindle. Book excerpt: The Manual of Tests and Criteria contains criteria, test methods and procedures to be used for classification of dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations, as well as of chemicals presenting physical hazards according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). As a consequence, it supplements also national or international regulations which are derived from the United Nations Recommendations on the Transport of Dangerous Goods or the GHS. At its ninth session (7 December 2018), the Committee adopted a set of amendments to the sixth revised edition of the Manual as amended by Amendment 1. This seventh revised edition takes account of these amendments. In addition, noting that the work to facilitate the use of the Manual in the context of the GHS had been completed, the Committee considered that the reference to the "Recommendations on the Transport of Dangerous Goods" in the title of the Manual was no longer appropriate, and decided that from now on, the Manual should be entitled "Manual of Tests and Criteria".

This book was released on 2019-01-11 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military has a stockpile of approximately 400,000 tons of excess, obsolete, or unserviceable munitions. About 60,000 tons are added to the stockpile each year. Munitions include projectiles, bombs, rockets, landmines, and missiles. Open burning/open detonation (OB/OD) of these munitions has been a common disposal practice for decades, although it has decreased significantly since 2011. OB/OD is relatively quick, procedurally straightforward, and inexpensive. However, the downside of OB and OD is that they release contaminants from the operation directly into the environment. Over time, a number of technology alternatives to OB/OD have become available and more are in research and development. Alternative technologies generally involve some type of contained destruction of the energetic materials, including contained burning or contained detonation as well as contained methods that forego combustion or detonation. Alternatives for the Demilitarization of Conventional Munitions reviews the current conventional munitions demilitarization stockpile and analyzes existing and emerging disposal, treatment, and reuse technologies. This report identifies and evaluates any barriers to full-scale deployment of alternatives to OB/OD or non-closed loop incineration/combustion, and provides recommendations to overcome such barriers.
