In considering the effects on Hiroshima and today. the effects of modern day weapons, students will come to understand the significance of the bombing and nuclear weapons today. Materials and space needed Sugar paper, thick markers, effects Note cards. Tables will be needed for small As the effects of a nuclear explosion are so vast and long lasting, there will group work and/or space for the obviously be overlap between the categories. Therefore, complete accuracy is not active version of this activity. essential. The activity is designed to portray the extreme effects of a nuclear explosion. Learning outcome By the end of the lesson: Instructions All students should be able to describe There are two versions of this activity, although they begin and end in the same way. some of the effects of a nuclear explosion. In small groups the students brainstorm what they think the effects of a nuclear explosion are and then feed back to the class. Most students will be able explain the long lasting nature of these effects. Version A – Small group version – Split students into small groups and provide each group with a set of effects Some students will be able to apply cards. On a large piece of sugar paper split it into eight columns. this to the bomb used in Hiroshima – Students then match up the effects on the cards to the time frame columns. and to UK nuclear weapons. There should be two to four cards per column. All students in the groups should agree where the cards go, with the answers reached through discussion. – Discuss the answers and their consequences as a class. Version B – Whole class, active version – Write the eight time frame categories on large pieces of paper and stick them up in order on the classroom wall. – Provide each student with an effect and ask them to go and stand next to the time frame they think is relevant. This must be done through discussion with other members of the class as they work out their position in relation to each other. Each time frame group should agree that the right people are in the group. This will involve conferring with each other and the groups on either side. When groups are sure they have the correct effects they stick them up with a temporary adhesive for easy movement. – Discuss the answers and their consequences as a class. Plenary Discuss some or all of the following questions as a class. – How similar were the effects to what you thought? Why were they similar/different? – How do you feel about Britain having such weapons? – When (if ever) should a weapon like this be used? – What do you think a nuclear winter could mean? Do you think this could happen in your lifetime? 8 Activity A: The effects of a nuclear explosion: Further information The effects on human beings can most miscarry or have a child with a range of about 215 warheads.

  • Explosive Chemical Hazards & Risk
    Safe Operating Procedure (1/13) EXPLOSIVE CHEMICAL HAZARDS & RISK MINIMIZATION _____________________________________________________________________ (For assistance, please contact EHS at (402) 472-4925, or visit our web site at http://ehs.unl.edu/) Background The Globally Harmonized System (GHS) of classification and labeling of chemicals defines an explosive materials as follows: a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such temperature and pressure and at such speed as to cause damage to the surroundings. Under the GHS system, there are seven divisions for explosives. • Unstable explosives • Division 1.1 – mass explosion hazards (i.e., nearly instant detonation of the entire quantity of explosive present) • Division 1.2 – projection hazards but not mass explosion hazards • Division 1.3 – minor mass explosion or projection hazards • Divisions 1.4 through 1.6 – very insensitive substances; negligible probability of accidental initiation or propagation Explosive chemicals will be identified with the pictogram shown below. In addition, Section 2 of the Safety Data Sheet (SDS) will include one or more of the hazard statements indicated below. • H200 Unstable; explosive • H201 Explosive; mass explosion hazard • H202 Explosive; severe projection hazard • H203 Explosive; fire, blast or projection hazard • H204 Fire or projection hazard • H205 May explode in fire Scope This SOP is limited in scope to those chemicals that meet the GHS definition of an explosive. However, it is important to understand that explosions can occur with chemicals that are not considered GHS explosives. For example, an explosion can occur with large-scale polymerization of a monomer. The reaction of monomers forming polymers is exothermic.

  • Uranium Mining and the U.S. Nuclear Weapons Program
    Uranium Mining and the U.S. Nuclear Weapons Program Uranium Mining and the U.S. Nuclear Weapons Program By Robert Alvarez Formed over 6 billion years ago, uranium, a dense, silvery-white metal, was created “during the fiery lifetimes and explosive deaths in stars in the heavens around us,” stated Nobel Laureate Arno Penzias.1 With a radioactive half-life of about 4.5 billion years, uranium-238 is the most dominant of several unstable uranium isotopes in nature and has enabled scientists to understand how our planet was created and formed. For at least the last 2 billion years, uranium shifted from deep in the earth to the rocky shell-like mantle, and then was driven by volcanic processes further up to oceans and to the continental crusts. The Colorado Plateau at the foothills of the Rocky Mountains, where some of the nation’s largest uranium deposits exist, began to be formed some 300 million years ago, followed later by melting glaciers, and erosion which left behind exposed layers of sand, silt and mud. One of these was a canary-yellow sediment that would figure prominently in the nuclear age. From 1942 to 1971, the United States nuclear weapons program purchased about 250,000 metric tons of uranium concentrated from more than 100 million tons of ore.2 Although more than half came from other nations, the uranium industry heavily depended on Indian miners in the Colorado Plateau. Until recently,3 their importance remained overlooked by historians of the atomic age. There is little doubt their efforts were essential for the United States to amass one of the most destructive nuclear arsenals in the world.

  • The Texas City Disaster
    National Hazardous Materials Fusion Center HAZMAT HISTORY The Texas City Disaster The National Hazardous Materials Fusion Center offers Hazmat History as an avenue for responders to learn from the past and apply those lessons learned to future incidents for a more successful outcome. This coincides with the overarching mission of the Fusion Center – to improve hazmat responder safety and enhance the decision‐making process during pre‐planning and mitigation of hazmat incidents. Incident Details: Insert Location and Date Texas City, TX April 16, 1947 Hazardous Material Involved Ammonium Nitrate Fertilizer Type (mode of transportation, fixed facility) Cargo Ship Overview The morning of 16 April 1947 dawned clear and crisp, cooled by a brisk north wind. Just before 8 am, longshoremen removed the hatch covers on Hold 4 of the French Liberty ship Grandcamp as they prepared to load the remainder of a consignment of ammonium nitrate fertilizer. Some 2,086 mt (2,300 t) were already onboard, 798 (880) of which were in the lower part of Hold 4. The remainder of the ship's cargo consisted of large balls of sisal twine, peanuts, drilling equipment, tobacco, cotton, and a few cases of small ammunition. No special safety precautions were in focus at the time. Several longshoremen descended into the hold and waited for the first pallets holding the 45 kg (100 lb) packages to be hoisted from dockside. Soon thereafter, someone smelled smoke, a plume was observed rising between the cargo holds and the ship’s hull, apparently about seven or eight layers of sacks down. Neither a 3.8 L (1 gal) jug of drinking water nor the contents of two fire extinguishers supplied by crew members seemed to do much good.

  • Explosives March 2017
    Hazard Communication Information Sheet reflecting the US OSHA Implementation of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Produced by the SCHC-OSHA Alliance GHS/HazCom Information Sheet Workgroup Info Explosives March 2017 How does OSHA’s Hazard Communication Standard (HCS 2012) define explosives? An explosive chemical is a solid or liquid chemical which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic chemicals are included even when they do not evolve gases. A pyrotechnic chemical is a chemical designed to produce an effect by heat, light, sound, gas or smoke or a combination of these as the result of non-detonative self-sustaining exothermic chemical reactions. An explosive item is an item containing one or more explosive chemicals. A pyrotechnic item is an item containing one or more pyrotechnic chemicals. An unstable explosive is an explosive which is thermally unstable and/or too sensitive for normal handling, transport, or use. An intentional explosive is a chemical or item which is manufactured with a view to produce a practical explosive or pyrotechnic effect. How does HCS 2012 classify explosives? The class of explosives includes: a) explosive chemicals; b) explosive items, except devices containing explosive chemicals in such quantity or of such a character that their inadvertent or accidental ignition or initiation does not cause any effect external to the device either by projection, fire, smoke, heat or loud noise; and c) chemicals and items not included in a) and b) above which are manufactured with the view to producing a practical explosive or pyrotechnic effect.

  • 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.
