Abstract

A physiological evaluation of modified models of impermeable/barrier chemical protective clothing

Project manager: Anna Marszałek Ph.D.

Project summary:

"The aim of the task was to improve the hygienic properties of impermeable protective clothing. Impermeable chemical protective clothing that is available on the market underwent physiological evaluation. Its modification was suggested. After another set of tests, the best solutions were selected, that is solutions that cause the lowest possible thermal strain during work in a hot environment.Two variants of chemical clothing protecting were tested: a two-part ensemble consisting of trousers and a jacket (L1) and a one-part boiler suit (L2). Control cotton clothing (B) - permeable to air and water vapour - consisted of two parts, a jacket and trousers.L2 clothing was modified; according to the tests it was slightly better than L1 clothing. Once prototype clothing was made, new physiological evaluation was conducted. The effectiveness of the changes was evaluated.All three types W1, W2, W3 make exercise in a hot environment possible, with lower physiological load and with better subjective sensations.The tests revealed that all the new models of protective clothing significantly improved work comfort, when compared with the basic model, i.e., L2 clothing. From among the new models, the model with forced ventilation (W3) made work in a hot environment with least physiological effort possible, it was tolerated best by the subjects and it made it possible to work 60% longer.The protective qualities of the newly produced prototypes of protective clothing were also tested for impermeability. All prototypes are impermeable to soaking with sprayed liquid and soaking with a stream of liquid."
