Tutt, the Proper Use and Handling of Explosives
THE PROPER USE AND HANDLING OF EXPLOSIVES BY IAN TUTT INSPECTOR OF EXPLOSIVES EXPLOSIVES INSPECTORATE DEPARTMENT OF MINES AND ENERGY The Proper Use and Handling of Explosives 1. Introductions The power released in a typical production blast is beyond the comprehension of most people. Few people understand the magnitude of the forces released at detonation. In a shot in which all goes well, the muffled sound of the explosives releasing their energy and the gentle rise and fall of the ground which contained the explosives does not give a true indication of the violent forces being released. One 25mmx200mm cartridge of explosives releases about 33 million horsepower of energy in .00004 of a second. The combined horsepower of all the equipment on any mine site pales into insignificance when compared to that of a single small cartridge of explosive. The power of a large production blast I would venture to say is beyond the comprehension of all, including myself. The powers unleashed by explosives are only equalled or bettered by Mother Nature yet with each passing day the respect for the very useful commodity has decreased to a point where many individuals and companies pay scant regard to its hazardous nature. Studies carried out in the USA have determined that 70 out of 1000 blasting accidents are fatal. If one reads these statistics quickly this may not seem as being a high strike rate, that is until you compare these statistics with that of other activities which we consider as high risk occupations. Excluding explosives, the statistics for other mining operations in the U.S.A is a fatality for 7 out of every 1000 accidents. -

Factors Affecting Anfo Fumes Production
FACTORS AFFECTING ANFO FUMES PRODUCTION James H. Rowland III and Richard Mainiero ABSTRACT For many years there have been small scale tests available for evaluating the toxic fumes production by cap- sensitive explosives (DOT Class 1.1), but these could not be used with blasting agents due to the large charge sizes and heavy confinement required for proper detonation. Considering the extensive use of blasting agents in construction and mining, there is a need to determine the quantities of toxic fumes generated by blasting agents. At the International Society of Explosive Engineers Twenty Third Annual Conference on Explosives and Blasting Technique in 1997, the authors reported on a facility for detonating large (4.54 kg), confined blasting agent charges in a controlled volume that had been constructed at the National Institute for Occupational Safety and Health’s Pittsburgh Research Lab’s Experimental Mine. Since 1997, this facility has been used to collect data on toxic fumes produced by the detonation of various ammonium nitrate/fuel oil (ANFO) mixtures and several cap-sensitive explosives. ANFO composition ranging from 1 to 10 percent (pct) fuel oil have been studied. As expected from previous studies, with an increase in fuel oil content the carbon monoxide production increases, while nitric oxide and nitrogen dioxide production decrease. The detonation velocity varies from 3,000 to 4,000 m/sec for the 1 to 10 pct range of fuel oil content, suggesting that ANFO mixes with improper fuel oil content may appear to detonate properly, while their fume production differs significantly from optimum. The study also considers such factors as degree of confinement, water contamination, and aluminum content on blasting agent fume production. -

The list covers not only explosives, but also blasting agents and detonators, all of which are defined as “explosive materials.” This notice contains the 2017 Annual List of Explosive Materials, which remains unchanged from the 2016 Annual List of Explosives. DATES: The list becomes effective [INSERT DATE OF PUBLICATION IN THE FEDERAL REGISTER]: FOR FURTHER INFORMATION, CONTACT: William E. Frye Jr., Chief, Explosives Industry Programs Branch; Firearms and Explosives Industry Division; Bureau of Alcohol, Tobacco, Firearms, and Explosives; United States Department of Justice; 99 New York Avenue, N.E., Washington, D.C. 20226; (202) 648-7120. SUPPLEMENTARY INFORMATION: Each material listed, as well as all mixtures containing any of these materials, constitute “explosive materials” under 18 U.S.C. 841(c). Materials constituting blasting agents are marked by an asterisk. While the list is comprehensive, it is not all-inclusive. The fact that an explosive material is not on the list does not mean that it is not within the coverage of the law if it otherwise meets the statutory definition in 18 U.S.C. -
Toxic Fume Comparison of a Few Explosives Used in Trench Blasting
Toxic Fume Comparison of a Few Explosives Used in Trench Blasting By Marcia L. Harris, Michael J. Sapko, and Richard J. Mainiero National Institute for Occupational Safety and Health Pittsburgh Research Laboratory ABSTRACT Since 1988, there have been 17 documented incidents in the United States and Canada in which carbon monoxide (CO) is suspected to have migrated through ground strata into occupied enclosed spaces as a result of proximate trench blasting or surface mine blasting. These incidents resulted in 39 suspected or medically verified carbon monoxide poisonings and one fatality. To better understand the factors contributing to this hazard, the National Institute for Occupational Safety and Health (NIOSH) carried out studies in a 12-foot diameter sphere to identify key factors that may enhance the levels of CO associated with the detonation of several commercial trenching explosives. The gaseous detonation products from emulsions, a watergel, and ANFO blasting agents as well as gelatin dynamite, TNT, and Pentolite boosters were measured in an argon atmosphere and compared with those for the same explosives detonated in air. Test variables included explosive formulation, wrapper, aluminum addition, oxygen balance, and density. Major contributing factors to CO production, under these laboratory test conditions, are presented. The main finding is the high CO production associated with the lack of afterburning in an oxygen poor atmosphere. Fumes measurements are compared with the manufacturer’s reported IME fume class and with the Federal Relative Toxicity Standard 30 CFR Part 15 in order to gain an understanding of the relative toxicity of some explosives used in trench blasting. INTRODUCTION Toxic gases such as CO and NO are produced by the detonation of explosives. -

Chapter 2 EXPLOSIVES
Chapter 2 EXPLOSIVES This chapter classifies commercial blasting compounds according to their explosive class and type. Initiating devices are listed and described as well. Military explosives are treated separately. The ingredi- ents and more significant properties of each explosive are tabulated and briefly discussed. Data are sum- marized from various handbooks, textbooks, and manufacturers’ technical data sheets. THEORY OF EXPLOSIVES In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases that expand rapidly with sufficient force to overcome confining forces; and (4) The energy released by the detonation of explosives produces four basic effects; (a) rock fragmentation; (b) rock displacement; (c) ground vibration; and (d) air blast. A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases. The gases continue to fill and expand the cracks until the gas pressure is too weak to expand the cracks any further, or are vented from the rock. The ingredients in explosives manufactured are classified as: Explosive bases. An explosive base is a solid or a liquid which, upon application or heat or shock, breaks down very rapidly into gaseous products, with an accompanying release of heat energy. -

Variables Associated with the Classification of Ammonium Nitrate – a Literature Review
Variables Associated with the Classification of Ammonium Nitrate – A Literature Review FINAL REPORT BY: Sean Gillis Sreenivasan Ranganathan Fire Protection Research Foundation, Quincy, MA March 2017 © 2017 Fire Protection Research Foundation 1 Batterymarch Park, Quincy, MA 02169-7417, USA Email: [email protected] | Web: nfpa.org/foundation —— Page ii —— FOREWORD Ammonium Nitrate (AN) “is a chemical compound produced in both solid and liquid forms that is commonly used in fertilizers”. The burning rate of technical-grade AN prill falls within the Class 2 oxidizer criteria in Annex G of NFPA 400, 2016. The loss history of AN also indicates potential for unstable reactive hazard properties, uncontrolled decomposition and/or detonation under circumstances that are not fully understood. In the most recent revision of NFPA 400, Hazardous Materials Code, the Technical Committee (TC) classified Ammonium Nitrate as a Class 2 Oxidizer. However recent hazardous material incidents involving AN have resulted in differing views regarding the reactivity of the compound and whether or not it should be considered an unstable reactive in NFPA 400. The different behaviors of AN in different fire situations make it difficult to determine the appropriate safe practices for AN storage and handling. There are also discrepancies between the NFPA and International Fire Code (IFC) classifications of Ammonium Nitrate. As a result there is a need for additional data to assist in the proper classification/treatment of AN. An examination of existing data involving the reactivity of AN will assist the NFPA 400 TC in determining the appropriate classification of Ammonium Nitrate, and perhaps point to a need for future Ammonium Nitrate testing. -

CRITERIA FOR A RECOMMENDED STANDARD OCCUPATIONAL EXPOSURE TO NITROGYLCERIN and ETHYLENE GLYCOL DINITRATE criteria for a recommended standard OCCUPATIONAL EXPOSURE TO NITROGLYCERIN and ETHYLENE GLYCOL DINITRATE U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health June 1978 For »ale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DISCLAIMER Mention of company name or products does not constitute endorsement by the National Institute for Occupational Safety and Health. DHEW (NIOSH) Publication No. 78-167 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and provide for the safety of workers occupationally exposed to an ever-increasing number of potential hazards. The National Institute for Occupational Safety and Health (NIOSH) evaluates all available research data and criteria and recommends standards for occupational exposure. The Secretary of Labor will weigh these recommendations along with other considerations, such as feasibility and means of implementation, in promulgating regulatory standards. NIOSH will periodically review the recommended standards to ensure continuing protection of workers and will make successive reports as new research and epidemiologic studies are completed and as sampling and analytical methods are developed. The contributions to this document on nitroglycerin (NG) and ethylene glycol dinitrate (EGDN) by NIOSH staff, other Federal agencies or departments, the review consultants, the reviewers selected by the American Industrial Hygiene Association, and by Robert B. O ’Connor, M.D., NIOSH consultant in occupational medicine, are gratefully acknowledged. The views and conclusions expressed in this document, together with the recommendations for a standard, are those of NIOSH.
