Wildfire firefighting is an extremely demanding occupation performed under hot environment. The use of personal ,protective clothing, (PPC) is needed to protect subjects from the thermal exposure. However, the additional use of PPC may increase the wildland firefighters' physiological strain, and consequently limit their performance. The aim of this study was to analyze the effect of four ...
PERSPIRATION POISONING OF ,PROTECTIVE CLOTHING, MATERIALS PART II ,MATHEMATICAL MODEL, FOR A COMPLEX ADSORPTION BED INTRODUCTION The ,mathematical modeling, of adsorption processes is well documented and the literature on the subject is extensive. One of the most complete and useful approaches is that proposed by Schneider and Smith1 for a bed
Models, based on computational fluid dynamics (CFD) have been developed to predict the performance of ,protective clothing, materials. Such ,models, complement testing by enabling property data from laboratory material testing to be used in predictions of integrated ,multilayer, garments under varying environmental conditions.

An alternative approach to ,modeling, was explored in which three dimensional (3-D) solubility parameters are used to obtain explicit estimates of solubility, and the solvent diffusion coefficient. These can then be used in Fickian diffusion equations to determine breakthrough times (BT) and steady state permeation rates (SSPR).

The method of calculating heat transfer in the "human - environment" system takes into account the variable thermal parameters and the geometric dimensions of the elements, the presence of internal heat sources and ...
The distribution of moisture in state-of-the-art firefighter ,protective clothing, was analyzed on a sweating torso. After one hour of sweating, only 35 % of moisture evaporated from the layers, but after another hour of drying out, only about 10 % of the supplied moisture remained in the ,clothing,.
