Detector for Chemical Warfare Agents CBRN Multi-Threat Flying Laboratory Flying Laboratory• September 22, 2013 • Page 1 Flying Laboratory for Monitoring CBRN Threats . The Flying Laboratory is a multipurpose UAV equipped to monitor for CBRN threats and/or perform video and thermal IR surveillance. Its capabilities are unique in the world. Car top launch Flying Laboratory• September 22, 2013 • Page 2 A Pioneer in the Field of Surveillance . Virtually all UAV development worldwide is focused on video surveillance. Research International (RI) is the world leader in development of UAV platforms for chemical, biological, radiological, and nuclear detection. The first demonstration in the world of real-time automated biodetection on a UAV was done by Research International and a U.S. Naval Research Laboratory team in September, 1996 at Dugway Proving Grounds: - Flight of the Biosensor, G. P. Anderson et. al., 1997 NRL Review. Flying Laboratory• September 22, 2013 • Page 3 The Flying Laboratory is an Integrated System . The Flying Laboratory integrates detection and collection products from the world’s best counter-terrorism equipment companies onto a single mini-class UAV. Multi-step protocols such as detection, collection, and analysis can be programmed by the user and automatically performed during flight. System capabilities can be modified to meet customer needs and budget within the constraints of UAV payload size and weight limits. Flying Laboratory• September 22, 2013 • Page 4 Key Flying Laboratory Features . Full CBRN monitoring plus video and thermal IR options . Instrumentation is controlled by a 1GHZ embedded micro-PC.

Flying Laboratory• September 22, 2013 • Page 5 Typical CBRN Capabilities & Response Times . Toxic chemicals and chemical warfare agents – Less than 10 seconds . Biological aerosol detection – 60 seconds . Biological aerosol collection – Collection time set by user . Radioisotopes and SNMs – Less than 2 seconds . Radiological aerosol collection – Collection time set by user Flying Laboratory• September 22, 2013 • Page 6 Customer-Specific System Configuration . It is not necessary to select all detection options . RI is willing to provide systems that have only customer-specific threat monitoring capabilities. System cost is more flexible. In some cases, additional threat monitoring modes may be added later. Avionics operation will be tailored to user needs; automatic landing available for less experienced. Flights may be preprogrammed or manually controlled by user. Some equipment may be export controlled and the customer may need to submit end user documentation. Flying Laboratory• September 22, 2013 • Page 7 Fitting CBRN Capabilities into a Mini-UAV . Putting a rectilinear-shaped payload into a UAV’s payload section would usually waste space. In addition, the process of air sampling may affect UAV flight behavior. RI uses 3D solid modeling software to optimize packing density and to ensure the payload is distributed properly relative to the center of gravity. Integrated CBRN package . The solid model is then loaded into a 3D computational fluid dynamics program which examines the effect of external modifications and air sampling on aerodynamics. This rigorous approach minimizes later surprises in the air.

The airframe has been adopted by users worldwide including the USA, Canada, New Zealand, Spain, Australia, Israel, S. Korea, U.K., Finland, Russia, India, Malaysia, Indonesia, Poland, Norway, Malta, Kuwait and Switzerland. Flying Laboratory• September 22, 2013 • Page 10 Toxic Chemical Detectors . There are perhaps thousands of chemicals that could be used by terrorists. One class are the conventional chemical warfare agents. A second class consists of those chemicals that are both toxic and commonly used in industry. A third class are combustible gases- not toxic, but potentially very dangerous. The Flying Laboratory monitors for all these threats by using multiple gas detection technologies. Flying Laboratory• September 22, 2013 • Page 11 Chemicals Generally Considered to be Warfare Agents . Chemical warfare agents are used to incapacitate, injure or kill at very small air concentrations. About 70 chemicals have been used in this way.

  • Piratox Sheet N5 Suffocating Agents and Phosphine
    Edition of October 2011 Piratox sheet #5: "Suffocating agents and phosphine Indicative list of concerned agents: Toxic compounds with suffocating action - Phosgene (CAS number: 75-44-5) - Chlorine (CAS number: 7782-50-5) - Methyl isocyanate (CAS number: 624-83-9) - But also: o Ammonia (CAS number: 7664-41-7) o Diphosgene or surpalite (CAS number: 503-38-8) o Chloropicrin (CAS number: 76-06-2) o Fluorine (CAS number: 7782-41-4) o Perfluoroisobutylene (CAS number: 382-21-8) o Fumigants o Marketed industrial and domestic products - Phosphine or PH3 or Hydrogen Phosphide (CAS number: 7803-51-2). ! Key points not to forget The 1st emergency step is the extraction of victims from the hazard area: rescuers must possess suitable breathing and eye protection. At ambient temperature (20°C) most suffocating agents are gases that penetrate the body via the respiratory route. They are thus poorly or non-persistent, frequently limiting victim decontamination needs to simple undressing. Most suffocating agents are heavier than air. They affect the respiratory system: glottis, bronchi, alveoli and cause eye damage. In pre-hospital settings, avoid any physical exertion that could promote the onset of pulmonary oedema. In general, the shorter the symptom onset time, the more serious the intoxication and the more severe the symptoms. Treatment is symptomatic only. All symptomatic choking gas victims must encouraged to rest, in a sitting position, under oxygen. The duration of surveillance for symptomatic subjects is of at least 12 to 24 hours. For Phosphine (PH3): o victims must be undressed and showered; o toxicity is respiratory, cardiac, renal and neurological; o subjects having inhaled PH3 and presenting with significant initial manifestations shall be monitored in the hospital for 48 to 72 hours, due to the risk of delayed acute pulmonary oedema.

  • Toxic Exposures Kathy L
    8 MODULE 8 Toxic Exposures Kathy L. Leham-Huskamp / William J. Keenan / Anthony J. Scalzo / Shan Yin 8 Toxic Exposures Kathy L. Lehman-Huskamp, MD William J. Keenan, MD Anthony J. Scalzo, MD Shan Yin, MD InTrODUcTIOn The first large-scale production of chemical and biological weapons occurred during the 20th century. World War I introduced the use of toxic gases such as chlorine, cyanide, an arsine as a means of chemical warfare. With recent events, such as the airplane attacks on the World Trade Center in New York City, people have become increasingly fearful of potential large-scale terrorist attacks. Consequently, there has been a heightened interest in disaster preparedness especially involving chemical and biological agents. The U.S. Federal Emergency Management Agency (FEMA) recommends an "all-hazards" approach to emergency planning. This means creating a simultaneous plan for intentional terrorist events as well as for the more likely unintentional public health emergencies, such as earthquakes, floods, hazardous chemical spills, and infectious outbreaks. Most large-scale hazardous exposures are determined by the type of major industries that exist and/or the susceptibility to different types of natural disasters in a given area. For example, in 1984 one of the greatest man-made disasters of all times occurred in Bhopal, India, when a Union Carbide pesticide plant released tons of methylisocyanate gas over a populated area, killing scores of thousands and injuring well over 250,000 individuals. The 2011 earthquake and tsunami in Japan demonstrated the vulnerability of nuclear power stations to natural disasters and the need to prepare for possible widespread nuclear contamination and radiation exposure.

  • Things to Be Done
    DRAFT MAY 2003 ANNEX 1: CHEMICAL AGENTS 1. Introduction The large-scale use of toxic chemicals as weapons first became possible during the First World War (1914–1918) thanks to the growth of the chemical industry. More than 110 000 tonnes were disseminated over the battlefields, the greater part on the western front. Initially, the chemicals were used, not to cause casualties in the sense of putting enemy combatants out of action, but rather to harass. Though the sensory irritants used were powerful enough to disable those who were exposed to them, they served mainly to drive enemy combatants out of the trenches or other cover that protected them from conventional fire, or to disrupt enemy artillery or supplies. About 10% of the total tonnage of chemical warfare agents used during the war were chemicals of this type, namely lacrimators (tear gases), sternutators and vomiting agents. However, use of more lethal chemicals soon followed the introduction of disabling chemicals. In all, chemical agents caused some 1.3 million casualties, including 90 000 deaths. During the First World War, almost every known noxious chemical was screened for its potential as a weapon, and this process was repeated during the Second World War (1939–1945), when substantial stocks of chemical weapons were accumulated, although rarely used in military operations. Between the two world wars, a high proportion of all the new compounds that had been synthesized, or isolated from natural materials, were examined to determine their utility as lethal or disabling chemical weapons. After 1945, these systematic surveys continued, together with a search for novel agents based on advances in biochemistry, toxicology and pharmacology.

  • ABSTRACT ZOU, YAN. Applications of [2+2+2] Cyclotrimerization
    ABSTRACT ZOU, YAN. Applications of [2+2+2] Cyclotrimerization Reactions and Light-Cleavable Groups in the Generation of Biologically Active Molecules. (Under the direction of Dr. Alexander Deiters). [2+2+2] Cyclotrimerization reactions are a versatile tool for constructing the poly- substituted carbo- and hetero- cyclic ring systems. A number of transition metal catalysts, such as Co, Ru, Rh, Ni and Pd complexes, have been applied. However, there are still regio- and chemo- selectivity issues present in [2+2+2] cyclotrimerization reactions, and only few applications of cyclotrimerization reactions in the synthesis of natural products have been reported. We aimed to develop cyclotrimerization reactions for the assembly of benzene and pyridine core structures found in natural products and for applications in the synthesis of fluorophores. Microwave irradiation, a more recent method used to assist organic reactions, was employed in various cyclotrimerization reactions. In order to obtain greater control over the chemoselectivity of these reactions, we developed a solid-supported method of cyclotrimerization reactions through the immobilization of an alkyne or diyne onto a polymer backbone. This methodology was applied to the assembly of poly-substituted pyridines. Furthermore, the microwave mediated cyclotrimerization methodology was utilized to synthesize various anthracene and azaanthracene fluorophores. Additionally, a cyclotrimerization reaction was used in key steps of the total synthesis of the natural products cryptoacetalide and the pyridine core of cyclothiazomycin. Currently, the cyclotrimerization reaction is being utilized in the ongoing synthesis of petrosasponglide L. Photolabile protecting groups (caging groups) have attracted considerable attention in the field of chemical biology. These caging groups are installed on biomolecules of interest to control their function with light.
