Assessing flammable storage cabinets as sources of VOC exposure in laboratories using real-time direct reading wireless detectors
Norton AE , Doepke A , Nourian F , Connick WB , Brown KK . J Chem Health Saf 2018 25 (5) 2-9 Herein we present the results of measurements using wireless direct-reading photoionization detector-based gas sensors to quantify concentrations of vapors of volatile organic compounds (VOCs) in and around flammable storage cabinets containing common organic solvents, including acetone, dichloromethane, trichloroethylene, and benzene. Such cabinets are commonly employed in laboratories to contain flammable liquids. A sensor array was deployed in a series of flammable storage cabinets in working laboratories. Measurements in cabinets containing bottles of typical solvents demonstrate that vapor concentrations gradually increase upon closing the cabinet door. The results suggest that these storage units can be a source of vapors of VOCs in laboratories and the unnecessary exposure of laboratory workers to chemical vapors. Ventilation of cabinets tended to lower maximum concentrations of VOCs. However, the efficacy of this engineering control was found to depend on the quality of the cabinet door seal, as well as having debris-free flame arrestors. Opening cabinet doors resulted in release of vapors to the laboratory atmosphere, which represents an unnecessary exposure risk for workers. A countermeasure aimed at improving the seal of previously opened solvent bottles reduced measured concentrations of VOCs in cabinets below the detector's limit of detection. |
Articles published and downloaded by public health scientists: analysis of data from the CDC Public Health Library, 2011-2013
Iskander J , Bang G , Stupp E , Connick K , Gomez O , Gidudu J . J Public Health Manag Pract 2015 22 (4) 409-14 OBJECTIVE: To describe scientific information usage and publication patterns of the Centers for Disease Control and Prevention (CDC) Public Health Library and Information Center patrons. DESIGN: Administratively collected patron usage data and aggregate data on CDC-authored publications from the CDC Library for 3 consecutive years were analyzed. SETTING: The CDC Public Health Library and Information Center, which serves CDC employees nationally and internationally. PARTICIPANTS: Internal patrons and external users of the CDC Library. MAIN OUTCOME MEASURE(S): Three-year trends in full-text article publication and downloads including most common journals used for each purpose, systematic literature searches requested and completed, and subscriptions to a weekly public health current literature awareness service. RESULTS: From 2011 to 2013, CDC scientists published a total of 7718 articles in the peer-reviewed literature. During the same period, article downloads from the CDC Library increased 25% to more than 1.1 million, completed requests for reviews of the scientific literature increased by 34%, and electronic subscriptions to literature compilation services increased by 23%. CONCLUSIONS: CDC's scientific output and information use via the CDC Library are both increasing. Researchers and field staff are making greater use of literature review services and other customized information content delivery. Virtual public health library access is an increasingly important resource for the scientific practice of public health. |
