Book Description
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 will help materials-textile engineers to develop high performance thermal protective clothing that can enhance the protection, safety, and comfort of firefighters. - Offers a helpful guide to the successful specification and design of high performance protective clothing to meet the high standards of today's regulatory framework - Introduces the new materials technical innovations that are transforming fire protective clothing - Explores the role of clothing from the operational perspective, including technical innovations - Offers a critical review of the test methods and existing standards to evaluate the thermal protective and physiological comfort performances of the fabrics and clothing

Book Description
The purpose of this research is to investigate numerically the heat and moisture transport in the firefighter protective clothing under the flash fire exposure. Numerical results help in understanding the basic mechanisms of the transient heat and moisture transport through the protective clothing, air gap, and human skin; and the effects of the moisture content on the thermo-physical properties of protective garments during the radiation heat exposure as well as during the cool-down period. Prediction of thermal performance of garment aids in designing and creating a new firefighter protective turnout gear in order to prevent and minimize tissue burns that result from the radiant energy produced by the fire and from the localized contact flame exposure. During fire extinguishing, firefighters often sweat profusely and are also exposed to the dousing water from a hose spray, which leads to accumulation of moisture in the turnout gear. Evaporation, condensation, desorption, and absorption of the moisture and energy associated with phase change can affect the temperature and energy flux to the skin. Traditional thermal protective garments rely passively on thermal properties of fabric and the entrapment of insulating air layers to resist heat flux from flash fire exposures. To improve the level of heat flux resistance of thermal protective garments, this research evaluates the feasibility of developing a novel garment system based on the utilization of a water-injection. For the intelligent garment investigated in this research, the liquid water will be injected in the outer layer of the garment through a capillary net composed of thin perforated tubes; the injection process will be activated by a temperature sensor embedded in the outer fabric layer. Therefore, the new turnout system augments this outer layer, by providing an active thermal barrier and acting as a thermal buffer against the high heat flux associated with the flash fire exposure while the remaining in.

Book Description
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
