Protective Clothing: Clothing designed to protect the individual against possible exposure to known hazards.Clothing: Fabric or other material used to cover the body.Thermal Conductivity: The heat flow across a surface per unit area per unit time, divided by the negative of the rate of change of temperature with distance in a direction perpendicular to the surface. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Heat Stress Disorders: A group of conditions that develop due to overexposure or overexertion in excessive environmental heat.FiresSunscreening Agents: Chemical or physical agents that protect the skin from sunburn and erythema by absorbing or blocking ultraviolet radiation.ManikinsSweating: The process of exocrine secretion of the SWEAT GLANDS, including the aqueous sweat from the ECCRINE GLANDS and the complex viscous fluids of the APOCRINE GLANDS.Suntan: An induced skin pigment (MELANIN) darkening after exposure to SUNLIGHT or ULTRAVIOLET RAYS. The degree of tanning depends on the intensity and duration of UV exposure, and genetic factors.Heat Exhaustion: A clinical syndrome caused by heat stress, such as over-exertion in a hot environment or excessive exposure to sun. It is characterized by SWEATING, water (volume) depletion, salt depletion, cool clammy skin, NAUSEA, and HEADACHE.TextilesRescue Work: Activities devoted to freeing persons or animals from danger to life or well-being in accidents, fires, bombings, floods, earthquakes, other disasters and life-threatening conditions. While usually performed by team efforts, rescue work is not restricted to organized services.Gloves, Protective: Coverings for the hands, usually with separations for the fingers, made of various materials, for protection against infections, toxic substances, extremes of hot and cold, radiations, water immersion, etc. The gloves may be worn by patients, care givers, housewives, laboratory and industrial workers, police, etc.Steam: Water in its gaseous state. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Wind: The motion of air relative to the earth's surface.Body Temperature Regulation: The processes of heating and cooling that an organism uses to control its temperature.Protective Devices: Devices designed to provide personal protection against injury to individuals exposed to hazards in industry, sports, aviation, or daily activities.Sunburn: An injury to the skin causing erythema, tenderness, and sometimes blistering and resulting from excessive exposure to the sun. The reaction is produced by the ultraviolet radiation in sunlight.Materials Testing: The testing of materials and devices, especially those used for PROSTHESES AND IMPLANTS; SUTURES; TISSUE ADHESIVES; etc., for hardness, strength, durability, safety, efficacy, and biocompatibility.Humidity: A measure of the amount of WATER VAPOR in the air.Body Temperature: The measure of the level of heat of a human or animal.Hot Temperature: Presence of warmth or heat or a temperature notably higher than an accustomed norm.Occupational Exposure: The exposure to potentially harmful chemical, physical, or biological agents that occurs as a result of one's occupation.Cold Temperature: An absence of warmth or heat or a temperature notably below an accustomed norm.Warm Ischemia: A tissue or organ remaining at physiological temperature during decreased BLOOD perfusion or in the absence of blood supply. During ORGAN TRANSPLANTATION it begins when the organ reaches physiological temperature before the completion of SURGICAL ANASTOMOSIS and ends with reestablishment of the BLOOD CIRCULATION through the tissue.Occupational Health: The promotion and maintenance of physical and mental health in the work environment.Microclimate: The climate of a very small area.Skin Neoplasms: Tumors or cancer of the SKIN.
