OCCUPATIONAL EXPOSURE TO DECOMPOSITION PRODUCTS of FLUOROCARBON POLYMERS U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health September 1977 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DHEW (NIOSH) Publication No. 77-193 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and safety of workers exposed to an ever-increasing number of potential hazards at their workplace. The National Institute for Occupational Safety and Health has projected a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the health effects of exposure. The Secretary of Labor will weigh these recommendations along with other considerations such as feasibility and means of implementation in developing regulatory standards. It is intended to present successive reports as research and epidemiologic studies are completed and as sampling and analytical methods are developed. Criteria and standards will be reviewed periodically to ensure continuing protection of the worker. I am pleased to acknowledge the contributions to this report on the decomposition products of fluorocarbon polymers by members of the NIOSH staff and the valuable constructive comments by the Review Consultants on the Decomposition Products of Fluorocarbon Polymers and by Robert B.

  • 3.3 Greenhouse Gas Emissions Final EIR | Spring Street Business Park Project
    3.3 Greenhouse Gas Emissions Final EIR | Spring Street Business Park Project 3.3 Greenhouse Gas Emissions 3.3.1 Overview This section describes the existing air quality conditions and applicable laws and regulations associated with air quality, as well as an analysis of the potential effects resulting from implementation of the proposed project. Information contained in this section is summarized from the Air Quality and Greenhouse Gas Technical Memorandum (Appendix B). 3.3.2 Environmental Setting Climate change refers to long-term changes in temperature, precipitation, wind patterns, and other elements of the earth's climate system. An ever-increasing body of scientific research attributes these climatological changes to GHG emissions, particularly those generated from the production and use of fossil fuels. While climate change has been a concern for several decades, the establishment of the Intergovernmental Panel on Climate Change by the United Nations and World Meteorological Organization in 1988 has led to increased efforts devoted to GHG emissions reduction and climate change research and policy. These efforts are primarily concerned with the emissions of GHGs generated by human activity, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), tetrafluoromethane, hexafluoroethane, sulfur hexafluoride (SF6), HFC-23 (fluoroform), HFC-134a (1,1,1,2-tetrafluoroethane), and HFC-152a (difluoroethane). In the U.S., the main source of GHG emissions is electricity generation, followed by transportation. In California, transportation sources (including passenger cars, light-duty trucks, other trucks, buses, and motorcycles) make up the largest source of GHG-emitting sources. The dominant GHG emitted is CO2, mostly from fossil fuel combustion.

  • Mark L. Robin Great Lakes Chemical Corporation Fluorine Chemicals Department P.O
    EVALUATION OF HALON ALTERNATIVES Mark L. Robin Great Lakes Chemical Corporation Fluorine Chemicals Department P.O. Box 2200 West Lafayette, IN 47906 INTRODUCTION Due to their implication in the destruction of stratospheric ozone, the production and use of the presently employed Halon fire extinguishing agents are being severely restricted. As a result, intense research programs have been undertaken in both the industrial and academic sectors to find replacements for these life-saving agents. Once a possible Halon alternative has been conceptualized, an evaluation of its properties is required to determine the actual performance of the agent. Foremost, one is interested in the fire suppression properties of the candidate. These fire suppression properties are related to the chemical and physical properties of the agent. For example, physical properties such as latent heats and heat capacities determine the ability of the agent to absorb heat, and the presence of certain functional groups such as halogens or trifluoromethyl groups imparts good fire suppression properties due to the interactions of these species with radical species present in the flame. However, good fire suppression properties are by no means the sole requirement for a suitable Halon replacement. For example, in streaming applications other physical properties, especially volatility, are important. The toxicological properties of any alternative agent must also be considered, since human exposure is inevitable, to both the neat and decomposed agent, especially in the case of total flood systems in normally occupied areas. Finally, the environmental impact of any new agent, for example its potential for ozone depletion or greenhouse warming, must also be considered.
