Medical Resources Division Technical Note: 008 ChemPro100i Libraries 8.3.6A answers while broad band questions (like is there a toxic chemical here) get a more generic answer. To increase specificity chemicals of interest are put into lists (“Libraries”) that are use specific. For example, clues (physical, biological, etc.) at the scene will lead responders to draw conclusions about the type of threat and then the responder can choose the correct library. If the responder reinterprets the on-scene clues the selected library in the ChemPro100i can be changed “on-the-fly.” In unknown environments it is not recommended to arbitrarily flip between libraries to “see what it could be” because libraries are use specific and applying a library in an improper situation may not give conclusive results. Changing libraries on-the-fly The “First Responder, TIC Classifier” and “TIC Confirm” libraries are designed to be used together. They share one common database and thus when moving from one The Library name and version number is shown on the library to another, the alarm from the previous main screen of the ChemPro100i library might stay on if the alarm criteria of the next is not met. Changing libraries are recommended only from What is a Library? 1. First Responder to The ChemPro100i is a multi-sensor TIC (Toxic 2. TIC Classifier to Industrial Chemical) and CWA (Chemical 3.

However, there is still a risk of false negative alarms (i.e. no alarm, although the specified chemical is present) in the following two scenarios: (1) The ChemPro100i may fail to alarm if it is turned on in a contaminated area. NEVER turn the ChemPro100i on in a contaminated environment. (2) The ChemPro100i may fail to alarm if the rate of concentration change as a function of time is greater than six minutes to the alarm level. Most CWA and / or TIC exposures to the ChemPro100i occur as a responder approaches a contaminated or hazardous location and the alarm limits are reached in seconds.

The “TIC Classifier” or “TIC-Confirm” libraries may be used subsequently to further classify and confirm the identity of an unknown chemical. The “First Responder” library shares a common database with the “TIC Classifier” library so it may be possible to have a “TIC Classifier” alarm come up when using the “First Responder” library. Even though one is not using the “TIC Classifier” library, this alarm should be considered valid.

  • A Quantum Chemical Study Involving Nitrogen Mustards
    The Pharmaceutical and Chemical Journal, 2016, 3(4):58-60 Available online www.tpcj.org ISSN: 2349-7092 Research Article CODEN(USA): PCJHBA Formation enthalpy and number of conformers as suitable QSAR descriptors: a quantum chemical study involving nitrogen mustards Robson Fernandes de Farias Universidade Federal do Rio Grande do Norte, Cx. Postal 1664, 59078-970, Natal-RN, Brasil Abstract In the present work, a quantum chemical study (Semi-empirical,PM6 method) is performed using nitrogen mustards (HN1, HN2 and HN3) as subjects in order to demonstrate that there is a close relationship between pharmacological activity and parameters such as formation enthalpy and number of conformers, which could, consequently, be employed as reliable QSAR descriptors. To the studied nitrogen mustards, a very simple equation o o relating log P, ΔH f and the number of conformers (Nc) was found: log P = [(log -ΔH f + logNc)/2]-0.28. Keywords QSAR, Descriptors, Formation enthalpy, Conformers, Semi-empirical, Nitrogen mustards, Log P Introduction It is well known that lipophilicity is a very important molecular descriptor that often correlates well with the bioactivity of chemicals [1]. Hence, lipophilicity, measured as log P, is a key property in quantitative structure activity relationship (QSAR) studies. In this connection, in the pharmaceutical sciences it is a common practice to use log P (the partition coefficient between water and octanol), as a reliable indicator of the hydrophobicity or lipophilicity of (drug) molecules [1-2]. For example, relying primarily on the log P is a sensible strategy in preparing future 18-crown-6 analogs with optimized biological activity [3].

  • High-Threat Chemical Agents: Characteristics, Effects, and Policy Implications
    Order Code RL31861 CRS Report for Congress Received through the CRS Web High-Threat Chemical Agents: Characteristics, Effects, and Policy Implications Updated September 9, 2003 Dana A. Shea Analyst in Science and Technology Policy Resources, Science, and Industry Division Congressional Research Service ˜ The Library of Congress High-Threat Chemical Agents: Characteristics, Effects, and Policy Implications Summary Terrorist use of chemical agents has been a noted concern, highlighted after the Tokyo Sarin gas attacks of 1995. The events of September 11, 2001, increased Congressional attention towards reducing the vulnerability of the United States to such attacks. High-threat chemical agents, which include chemical weapons and some toxic industrial chemicals, are normally organized by military planners into four groups: nerve agents, blister agents, choking agents, and blood agents. While the relative military threat posed by the various chemical types has varied over time, use of these chemicals against civilian targets is viewed as a low probability, high consequence event. High-threat chemical agents, depending on the type of agent used, cause a variety of symptoms in their victims. Some cause death by interfering with the nervous system. Some inhibit breathing and lead to asphyxiation. Others have caustic effects on contact. As a result, chemical attack treatment may be complicated by the need to identify at least the type of chemical used. Differences in treatment protocols for the various high-threat agents may also strain the resources of the public health system, especially in the case of mass casualties. Additionally, chemical agents trapped on the body or clothes of victims may place first responders and medical professionals at risk.

  • Managing Hazardous Materials Incidents
    Blister Agent (HN1, HN2, HN3) Blister Agents Nitrogen Mustard (HN-1, HN-2, and HN-3) Patient Information Sheet This handout provides information and follow-up instructions for people who have been exposed to nitrogen mustards. What are nitrogen mustards? Nitrogen mustards are compounds that were initially developed as chemical warfare agents or pharmaceuticals. They have never been used on the battlefield. HN-2 has been used in chemotherapy. What immediate health effects can be caused by exposure to nitrogen mustards? Nitrogen mustards cause injury to the skin, eyes, nose and throat. Eye damage may occur within minutes of exposure. Nausea and vomiting also may occur shortly after exposure. Skin rashes, blisters, and lung damage may develop within a few hours of exposure but may take 6 hours or more. Nitrogen mustards can also suppress the immune system. Can nitrogen mustard poisoning be treated? There is no antidote for nitrogen mustard, but its effects can be treated and most exposed people recover. Immediate decontamination reduces symptoms. People who have been exposed to large amounts of nitrogen mustard will need to be treated in a hospital. Are any future health effects likely to occur? Adverse health effects, such as chronic respiratory diseases, may occur from exposure to high levels of these agents. Severe damage to the eye may be present for a long time following the exposure. What tests can be done if a person has been exposed to nitrogen mustard? There are no routine tests to confirm exposure. Where can more information about nitrogen mustard be found? More information about nitrogen mustards can be obtained from your regional poison control center; the Agency for Toxic Substances and Disease Registry (ATSDR); your doctor; or a clinic in your area that specializes in toxicology or occupational and environmental health.

  • Protect Laboratory Chemicals from Use in a Terrorist Attack
    Protect Laboratory Chemicals from Use in a Terrorist Attack Overview Chemicals and reagents used for research and development, testing, monitoring, or education are critical to production, nonproduction, diagnostic, and pharmaceutical laboratory services. However, in the wrong hands, some of these same chemicals can be used for great harm. What Is CFATS? In 2006, Congress authorized the U.S. Department of Homeland Security (DHS) to establish the Chemical Facility Anti-Terrorism Standards (CFATS) program. Managed by the Cybersecurity and Infrastructure Security Agency (CISA), the CFATS program identifies and regulates high-risk chemical facilities to ensure that security measures are in place that reduce the risk of certain chemicals being weaponized. Appendix A of the CFATS regulation lists more than 300 chemicals of interest (COI) and their respective screening threshold quantity (STQ), concentration, and security issues. If released, stolen or diverted, and/or used as a contaminant, these COI have the potential to cause significant loss of human life and/or health consequences. Any individual or facility in possession of COI that meets or exceeds the STQ and concentration must report those chemicals to CISA through an online survey called a Top-Screen. COI Commonly Found in Laboratories Laboratories that use COI are considered chemical facilities under CFATS and may be subject to its regulations. Some of the commonly reported COI include, but are not limited to: • Aluminum (powder) • Sarin • Ammonium perchlorate • Sodium nitrate • DF (Methyl phosphonyl difluoride) • Soman [o-Pinacolyl • HN1, HN2, and HN3 (Nitrogen mustard-1, 2, 3) methylphosphonofluoridate] • Hydrogen fluoride (anhydrous) • Sulfur Mustard (Mustard gas (H)) • Hydrogen peroxide (conc.

  • Bioterrorism, Chemical Weapons, and Radiation Terrorism
    BIOTERRORISM, CHEMICAL WEAPONS, AND RADIATION TERRORISM INTRODUCTION Large-scale terrorism with biological, chemical, or radiological weapons has yet to happen in the United States. But the 9/11 attack clearly showed that the country could be vulnerable to a determined enemy and because biological, chemical, and (to a lesser degree) radiological weapons do not require enormous technical expertise to develop or use they would be an attractive alternative to use for a terrorist attack. In addition, a terrorist attack using one of these agents would not have to kill many people or produce a large number of casualties to be extremely disruptive. In the United States in 2001, letters containing anthrax spores were mailed to media offices and two United States senators. Five people were killed and 17 were infected, but the incident also created an enormous amount of fear, the investigation required huge amounts of time and money, the cleanup of postal and governmental offices was estimated to have cost over $1 billion, and there were untold number of emergency room visits and countless numbers of calls to health care facilities and public health agencies. The use of biological and chemical weapons for warfare dates back many centuries, and it has continued up to the present. The use of biological, chemical, or radiological weapons for the purposes of terror is also very old, but there are important differences between warfare and terrorism. Terrorism can be defined as a deliberate act of violence that is intended to cause harm but to also make a political or ideological statement, so the use of these non-traditional weapons for terror would be likely to occur outside of the context of an obvious, declared armed conflict and the targets would not be military but civilian.
