Shawn Deaton and published by . This book was released on 2020 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manikins have been used for almost 100 years to help understand the properties of clothing materials and garments. Data from sweating manikins also have been used within thermoregulation computer models to estimate the physiological responses of humans. In recent years, the development of the ManikinPC system has incorporated a thermoregulation model into a thermal sweating manikin system to provide a real-time analysis of predicted physiological response. This paper describes an experimental study that demonstrates the utility of this manikin-model system to predict the effects of three composite materials used in firefighter suits on human physiological response. This study addresses this question: Can ManikinPC emulate the physiological response of a controlled wear trial using three different sets of firefighter turnout gear in one environmental condition? The average core temperature, skin temperature, and sweat loss from human subjects are compared with the predicted values generated from the manikin coupled with the model. Results indicate similar trends and ranking of the three suits. The data revealed slightly higher predictive responses from the manikin-model system compared with the collected human data.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research studies relationships between measurements of heat loss through firefighter turnout ensembles measured using a sweating thermal manikin and a guarded sweating hot plate. Measurement techniques and results are compared. These two measures of heat loss are also compared on their ability to explain thermal heat stress. The assessments of thermal heat stress were provided in a report from an earlier physiological study where human responses were evaluated during wear trials of firefighter protective gear. The focus of this research was on the role of the instrumented sweating manikin as a supplemental tool in predicting heat stress. Its human form makes it a logical intermediary tool between a flat skin model (hot plate) and human subject testing. Thus, it was decided to investigate its role by using it to evaluate six firefighter turnout ensembles where there was existing data available for comparison to both hot plate and physiological test results. The results of this study indicate that sweating thermal manikin measurements provide a fuller explanation and prediction of heat stress assessments in physiological wear trials than provided by a sweating hot plate. This is attributed to the ability of manikin tests to evaluate the effects of garments' insulating air layers and the contribution of clothing design features to the total thermal burden. This research provides insights into the use of instrumented manikins as research tools and as means of providing information useful for predicting and explaining the results of physiological wear trials of firefighter protective clothing. Thermal manikins are also shown to be valuable tools for evaluating the distribution of heat loss through different areas of protective gear.

This book was released on 2012 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweating skin models and instrumented thermal manikins are commonly used to assess the heat stress potential of materials used in protective clothing. This research describes the relationship observed between heat loss through firefighter turnout ensembles measured using a sweating thermal manikin and that measured with a guarded sweating hot plate. Materials and garment level instrument measures are compared on the basis of their ability to predict human physiological responses related to heat stress in firefighter turnout systems. Sweating hot plate and manikin test results for selected firefighter turnout ensembles are compared to human wear studies in which firefighter turnout ensembles were worn in different environmental conditions. Sweating manikin tests are used to explain differences in the human physiological response and how these measures are related to turn-out heat transfer properties measured using a sweating hot plate. This study confirms the utility of sweating manikins in characterizing the effects of clothing design, fit, and layers on heat and moisture transfer. Thermal manikins are shown to be valuable tools for evaluating the distribution of heat loss through different areas of protective gear.

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

Available in PDF, EPUB and Kindle. Book excerpt: Manikins for Textile Evaluation is a key resource for all those engaged in textile and apparel development and production, and for academics engaged in research into textile science and technology. Creating garments that work with the human form, both stationary and in motion, is a complex task that requires extensive testing and evaluation. Manikins allow for performance testing of textiles in a safe, controlled, and appropriate environment, and are a key element in developing new textile products. Everyday apparel needs to be assessed for comfort, sizing and fit, and ergonomics, while technical and protective garments require extensive safety and performance testing. Manikins therefore range from simple representations of the human body to complex designs that simulate body temperature, sweating, and motion. Manikins are safe for use in hazardous testing environments, such as fire and flame protection, where wearer trials would be impossible. This book provides extensive coverage of manikin-based evaluation of protective, heat and flame resistant, medical, and automotive textile applications. The role of manikins in the development of day-to-day garments is also discussed, including fit, comfort, and ergonomics. The book is a key resource for all those engaged in textile and apparel development and production, and for academics engaged in research into textile science and technology. Delivers theoretical and practical guidance on evaluation using manikins that is of benefit to anyone developing textile products Offers a range of perspectives on high-performance textiles from an international team of authors with diverse expertise in academic research, and textile development and manufacture Provides systematic and comprehensive coverage of the topic from fabric construction, through product development, to the range of current and potential applications that exploit high-performance textile technology

This book was released on 2020 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Total heat loss (THL) in the National Fire Protection Association (NFPA) 1971, Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting , standard is the index used to evaluate the heat loss capability of firefighters' turnout gear. The true evaporative resistance (Ret) covered in ASTM F1868, Test Method for Thermal and Evaporative Resistance of Clothing Materials Using a Sweating Hot Plate , Part B is the other index used to predict the garment's breathability, which is not included in NFPA 1971. To explore the better index among these two values for predicting the human physiological response under warm conditions. This paper reported a human subject study to measure the physiological responses of firefighters conducting a designed protocol while wearing three different types of turnout garments in a warm condition. These three garments had similar THL indexes but different Ret. The results showed that firefighters dropped out only when they wore garments with the highest Ret value. A significant difference in the maximum change in heart rate was found between firefighters wearing garments with different Ret values. An apparent difference in core temperature when all firefighters were present was observed when wearing the garment with the highest Ret value. No obvious difference was found between subjects wearing different garments. The work demonstrated the need to evaluate the Ret in addition to the THL for heat strain evaluations of protective clothing.

This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological stress in fire fighters caused by a turnout suit with and without a water barrier composed of a microporous membrane was measured during simulated fire fighting work. Eight experienced fire fighters (23 - 47 years old) were randomly exposed to three wear trials consisting of a standardized treadmill test of 25 min of hard work at Ta of 50 °C, and P of 1440 W/m2, interrupted by a 25-min break at Ta of 22 °C, and followed by 30 min of moderate work at Ta of 40 °C, and P of 258 - 177 W/m2. Body temperatures and heart rate increased steadily during the work periods up to the individual heat tolerance limits. The body temperatures were higher when the suit with a membrane was worn. The difference in rectal temperature was not significant, but the difference in mean skin temperature was statistically significant at the end of the hard work (p=0.05). More sweat condensated in the underclothing, and the subjective evaluation of physical exertion, thermal discomfort and sensation were higher for the suit with the membrane, but only slight statistically significant differences were found. The corrected thermal insulation (ITcorr) and the water vapor permeability (Me) measured with the aid of a sweating thermal manikin were higher for the suit without the membrane.

This book was released on 2002 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The body protection of soldiers working in extreme climatic or tropical conditions requires a particular protective clothing that allows them to perform their mission. Protective suits, increasing insulation and reducing sweat evaporation, decrease their physiological capabilities and their ability to work in hot and wet environment. The instrumented thermal and sweating manikin is fitted to simulate human sweating characteristics. In addition to the measurement of vapour permeation, it also allows to quantity precisely the maximal sweat transfert of protective clothing. This measurement allows to underline the part of global insulation due to the wet exchange of the worn protective equipment. Different concepts of clothing are tested with the thermal and sweating instrumented manikin, in comparison with the sweat flow of the naked manikin skin: butyl, battle dress, NBC protective suit (charcoal foam and fabric), and different models of new generation permeable clothing. The test protocol allows to determine quickly the efficiency of sweat permeation through protective equipment. The sweat evaporation is strongly limited by the butyl suit, but in comparaison with naked manikin, NBC permeable protective clothing allow significant flow rate. This evaluation is a complementary and obligatory preliminary step before physiological test on human in laboratory and on the field.

Available in PDF, EPUB and Kindle. Book excerpt: Thermal Protective Clothing for Firefighters explores the materials, design, and usage of thermal protective clothing. The characteristics of fire hazards are discussed in detail, and the thermal environments faced by firefighters in these fire hazards are also examined. The different types of potential burn injuries and the heat stress that occurs to firefighters’ bodies when exposed to such thermal environments are analyzed. Furthermore, the development of various high performance fibers and fabrics for thermal protective clothing is discussed. The test methods and existing standards to evaluate the thermal protective and physiological comfort performances of the fabrics and clothing are critically reviewed. Recent developments in the field of fire- and heat-resistant materials have led to significant improvements in thermal protective clothing. In parallel with this, the complexity and risk levels of fires, especially in industrial-storage facilities, and developments in health and safety cultures have increased the demand for high-performance heat- and flame-resistant clothing and equipment, designed to mitigate skin burn injuries and reduce risk of death from fire hazards. Throughout the work, the gaps and limitations in existing test methods and standards are identified, and approaches are recommended for the development of enhanced test methods. Scenario modeling and its implications for firefighters’ protective clothing is discussed, and various factors affecting performance are established. Finally, various key issues related to thermal protective clothing are addressed to guide the future research in the field of thermal protective clothing for firefighters.

This book was released on 2000 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research studied the relationship between heat transfer measured using a guarded sweating hot plate test method and the actual comfort and heat stress performance of firefighter turnout clothing. Controlled environment wear trials were conducted using the climate chamber available at the Center for Research on Textile Protection and Comfort (T-PACC) in the College of Textiles at North Carolina State University. Seven professional firefighters participated in these studies. Two different wear test protocols were performed to simulate two levels of work activity, climate conditions, and clothing and equipment variables: One protocol featured light to moderate work activity in a mild climate (21°C, 65% RH). Subjective and objective measures of human psychological and physiological response were applied to quantify and rate performance in several categories. A separate study was conducted to determine the heat stress experienced by firefighters performing moderate work activities in a warm environment (39°C, 35% RH).
