A Study on Total Heat Loss of Clothing Materials for Firefighters’ Protective Clothing
Clothing is often made of materials that impede the flow of heat and moisture from the skin to the environment. Consequently, people may suffer from heat stress or cold stress when wearing clothing in different environmental conditions. Therefore it is important to quantify the thermal resistance and evaporative resistance of clothing materials and to consider these properties when selecting ma...
متن کاملPrediction of WBGT-based clothing adjustment values from evaporative resistance
Wet bulb globe temperature (WBGT) index is used by many professionals in combination with metabolic rate and clothing adjustments to assess whether a heat stress exposure is sustainable. The progressive heat stress protocol is a systematic method to prescribe a clothing adjustment value (CAV) from human wear trials, and it also provides an estimate of apparent total evaporative resistance (Re,T...
متن کاملA Heat Transfer Model for Firefighters’ Protective Clothing, Continued Developments in Protective Clothing Modeling
In the year 2000, a paper entitled ‘‘A Heat Transfer Model for Firefighters’ Protective Clothing’’ was published in Volume 36, No. 1, of Fire Technology, and it received the 2001 Harry C. Bigglestone Award for Excellence in Written Communication of Fire Protection Concepts from The Fire Protection Research Foundation. Since the publication of this paper, there has been additional development of...
متن کاملMaximum allowable exposure to different heat radiation levels in three types of heat protective clothing
To determine safe working conditions in emergency situations at petro-chemical plants in the Netherlands a study was performed on three protective clothing combinations (operator's, firefighter's and aluminized). The clothing was evaluated at four different heat radiation levels (3.0, 4.6, 6.3 and 10.0 k∙W∙m-2) in standing and walking posture with a thermal manikin RadMan™. Time till pain thres...
متن کاملHeat gain from thermal radiation through protective clothing with different insulation, reflectivity and vapour permeability.
The heat transferred through protective clothing under long wave radiation compared to a reference condition without radiant stress was determined in thermal manikin experiments. The influence of clothing insulation and reflectivity, and the interaction with wind and wet underclothing were considered. Garments with different outer materials and colours and additionally an aluminised reflective ...
