This book was released on 1992 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emergency spill response activities often require protective clothing that is an effective barrier to a wide range of chemicals and chemical mixtures. The U.S. Coast Guard Chemical Response Suit uses fluoropolymer film-based Challenge® materials as the encapsulating suit material to achieve high barrier. The results of over 300 permeation tests previously conducted by the U.S. Coast Guard indicate that these materials are excellent barriers to many chemicals and mixtures, however, several chemicals do permeate them. An empirical model or rule system was developed using this data set to predict whether permeation will be detected within three hours at 25°C at a detection sensitivity of 0.05 ?g/cm2-min. The model predicts permeation based on the structure and size of the chemical, and when applied to the existing data base, correctly predicts the permeation behavior for 93% of the chemicals tested. A computerized version of the permeation data base and prediction model was developed for Macintosh® computers using SuperCard® for use by personnel with minimal permeation or chemistry training. The computer system provides capabilities to search the existing permeation database and make predictions using the empirical model.

Download or read book Selection and Use of Molecular Parameters to Predict Permeation Through Fluoropolymer Based Protective Clothing Material written by CM. Hansen and published by . This book was released on 1992 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simple molecular parameters, describing affinity and size, are shown to model permeation of Challenge 5100R and Challenge 5200R materials (fiber-reinforced fluoropolymers). Solubility parameter eodels based on permeation test data are described, and shown to be very similar for the two materials. Figures combining both solubility parameter affinities and size parameters are presented as potential predictive models for the barrier effectiveness of the materials. The size parameter and the presence of double bonds are shown to have a profound influence on permeation. The results from this model are described, and evaluated using data obtained before and after model development. The model is compared with a different empirical model developed by Arthur D. Little, Inc. (ADL). The ADL model uses a rule system to predict permeation through the fluoropolymer materials based on the structure and size of the challenge chemical. Both approaches correctly describe the permeation behavior in about 90% of the cases in the present data set.

This book was released on 1988 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approaches for predicting the permeation resistance of chemical protective clothing polymers were investigated and assessed for accuracy and applicability to the Premanufacture Notification (PMN) review process of the U.S. Environmental Protection Agency (EPA) Office of Toxic Substances (OTS). The approaches emphasize the prediction of cumulative permeation and include: (1) a predictive model based on Fickian diffusion theory and (2) test methods for directly assessing permeation resistance.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, interest in and testing of chemical protective clothing has increased significantly. Permeation and immersion testing have produced large amounts of breakthrough time, permeation rate, and weight-change information on clothing materials. This information has been compiled into a relational data base system which operates on a personal computer and is available as a commercial product, CPCbase. Also included in the system are descriptions of the clothing materials tested, their sources, and the literature references for the data. The system is menu-driven with fixed search routines and produces formatted reports. In addition, the user can add new or proprietary information and can tailor searches and reports to meet specific needs.

Download or read book Protective Clothing written by F. Wang and published by Elsevier. This book was released on 2014-08-04 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protective clothing protects wearers from hostile environments, including extremes of heat and cold. Whilst some types of protective clothing may be designed primarily for non-thermal hazards (e.g. biological hazards), a key challenge in all protective clothing remains wearer comfort and the management of thermal stress (i.e. excessive heat or cold). This book reviews key types of protective clothing, technologies for heating and cooling and, finally, modeling aspects of thermal stress and strain. Explores different types of protective clothing, their uses and their requirements, with an emphasis on full-scale or prototype clothing, including immersion suits, body armour and space suits Considers novel and commercial technologies for regulating temperature in protective clothing, including phase change materials, shape memory alloys, electrically heated clothing and air and water perfusion-based cooling systems Reviews the human thermoregulatory system and the methods of modelling of thermal stress in protective clothing through various conditions, including cold water survival and firefighting
