  • Refrigerant Safety Refrigerant History
    Refrigerant Safety The risks associated with the use of refrigerants in refrigeration and air­conditioning equipment can include toxicity, flammability, asphyxiation, and physical hazards. Although refrigerants can pose one or more of these risks, system design, engineering controls, and other techniques mitigate this risk for the use of refrigerant in various types of equipment. Refrigerant History Nearly all of the historically used refrigerants were flammable, toxic, or both. Some were also highly reactive, resulting in accidents (e. g., leak, explosion) due to equipment failure, poor maintenance, or human error. The task of finding a nonflammable refrigerant with good stability was given to Thomas Midgley in 1926. With his associates Albert Leon Henne and Robert Reed McNary, Dr. Midgley observed that the refrigerants then in use comprised relatively few chemical elements, many of which were clustered in an intersecting row and column of the periodic table of elements. The element at the intersection was fluorine, known to be toxic by itself. Midgley and his collaborators felt, however, that compounds containing fluorine could be both nontoxic and nonflammable. The attention of Midgley and his associates was drawn to organic fluorides by an error in the literature that showed the boiling point for tetrafluoromethane (carbon tetrafluoride) to be high compared to those for other fluorinated compounds. The correct boiling temperature later was found to be much lower. Nevertheless, the incorrect value was in the range sought and led to evaluation of organic fluorides as candidates. The shorthand convention, later introduced to simplify identification of the organic fluorides for a systematic search, is used today as the numbering system for refrigerants.

  • Flammable Refrigerants Firefighter Training
    Flammable refrigerants firefighter training: Hazard assessment and demonstrative testing FINAL REPORT BY: Noah L. Ryder, P. E. Stephen J. Jordan Fire & Risk Alliance, LLC. Rockville, Maryland, USA. Peter B. Sunderland, Ph.D. University of Maryland Department of Fire Protection Engineering College Park, Maryland, USA. May 2019 © 2019 Fire Protection Research Foundation 1 Batterymarch Park, Quincy, MA 02169-7417, USA Email: [email protected] | Web: nfpa.org/foundation ---page intentionally left blank--- —— Page ii —— FOREWORD The ongoing push toward sustainability of refrigeration systems will require the adoption of low global warming potential (GWP) refrigerants to meet the shift in environmental regulations. Fire safety is a lingering issue with the new age of flammable refrigerants being adopted and first responders may not be familiar with the change in material hazards or the appropriate response procedures required to safely handle these fire scenarios. This project is part of the overall two-year project with a goal to enhance firefighter safety and reduce potential injury by providing training on the hazards from appliances with flammable refrigerants. It will document the information about flammable refrigerants technologies and the hazards to emergency responders and develop interactive training modules to transfer the knowledge to the fire service. This report is focused to develop material documenting the hazards associated with flammable refrigerant technologies and the risks posed to the first responders. The material documentation included a literature review, Task 1, identifying baseline information on flammable refrigerants, their existing usage and implementation into products, potential integration into future technologies, and finally any existing guidance and best practices on response and tactics.

  • Product Stewardship Summary Carbon Tetrachloride
    Product Stewardship Summary Carbon Tetrachloride May 31, 2017 version Summary This Product Stewardship Summary is intended to give general information about Carbon Tetrachloride. It is not intended to provide an in-depth discussion of all health and safety information about the product or to replace any required regulatory communications. Carbon tetrachloride is a colorless liquid with a sweet smell that can be detected at low levels; however, odor is not a reliable indicator that occupational exposure levels have not been exceeded. Its chemical formula is CC14. Most emissive uses of carbon tetrachloride, a “Class I” ozone-depleting substance (ODS), have been phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol). Certain industrial uses (e.g. feedstock/intermediate, essential laboratory and analytical procedures, and process agent) are allowed under the Montreal Protocol. 1. Chemical Identity Name: carbon tetrachloride Synonyms: tetrachloromethane, methane tetrachloride, perchloromethane, benzinoform Chemical Abstracts Service (CAS) number: 56-23-5 Chemical Formula: CC14 Molecular Weight: 153.8 Carbon tetrachloride is a colorless liquid. It has a sweet odor, and is practically nonflammable at ambient temperatures. 2. Production Carbon tetrachloride can be manufactured by the chlorination of methyl chloride according to the following reaction: CH3C1+ 3C12 —> CC14 + 3HC1 Carbon tetrachloride can also be formed as a byproduct of the manufacture of chloromethanes or perchloroethylene. OxyChem manufactures carbon tetrachloride at facilities in Geismar, Louisiana and Wichita, Kansas. Page 1 of 7 3. Uses The use of carbon tetrachloride in consumer products is banned by the Consumer Product Safety Commission (CPSC), under the Federal Hazardous Substance Act (FHSA) 16 CFR 1500.17.

  • Toxicological Profile for Carbon Tetrachloride
    CARBON TETRACHLORIDE 175 5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 5.1 PRODUCTION Carbon tetrachloride is produced by exhaustive chlorination of a variety of low molecular weight hydrocarbons such as carbon disulfide, methane, ethane, propane, and ethylene dichloride (HSDB 2004). It is also produced by thermal chlorination of methyl chloride (HSDB 2004). Carbon tetrachloride is a feedstock for chlorofluorocarbon gases, such as dichlorodifluoromethane (F-12) and trichlorofluoro­ methane (F-11), which were used as aerosol propellants in the 1950s and 1960s (Holbrook 1991). Following this, the growth rate for the production of carbon tetrachloride averaged 10.7% per year from 1960 to 1970 (Holbrook 1991). This rate slowed to 7.2% per year from 1970 to 1974, when the production of this chemical was at its peak, as other forms of propellants became commercially available (Anonymous 1981; Holbrook 1991). The FDA banned the sale of carbon tetrachloride in any product used in the home and the EPA regulated the use of chlorofluorocarbon gases as aerosols or propellants. Since then, production of carbon tetrachloride has declined at approximately 8% a year from 1974 to 1994 (Anonymous 1995; Holbrook 1991). Carbon tetrachloride is currently manufactured in the United States by Vulcan Materials Company at two plants: Geismar, Louisiana and Wichita, Kansas, with a combined 130 million pound capacity (HSDB 2004; SRI 2004). It should be noted, however, that these capacities are flexible, since other chlorinated solvents are made using the same equipment (SRI 2004). This recent decline in production is due to the adoption of an international agreement (the Montreal Protocol) to reduce environmental concentrations of ozone-depleting chemicals (including carbon tetrachloride), and to the provisions of Title VI of the Clean Air Act Amendments of 1990 addressing these chemicals.
