This article deals with the reaction of the female body to the use of an insulation chemical protective clothing combined with working - thermal and mental stress to which the female is exposed. The article provides a concise overview of protective chemical clothings and factors affecting their comfort; it describes the regularities corresponding to the physiological reaction, important for the body’s reaction to the use of a chemical protective clothing. Further, the article contains a description of the measurement and evaluation of physiological parameters of non-acclimated women during testing of these clothings and, finally, comparison with the results for males under the same stress which is unfavourable for women.

Based on long-term experiences cooperation between the Laboratory of Toxic Compounds at the National Institute for Nuclear, Chemical and Biological Protection and the Nuclear, Chemical and Biological Defence Institute of the University of Defence in Brno an interlaboratory double-sided comparison has been established in recent time. The interlaboratory comparison of methods is one of several quality management tools according to ČSN EN ISO/IEC 17 025:2005. In the Czech Republic a commercial available comparison system for breakthrough time determination of chemical warfare agents through protection material actually does not exist. In fact the methods are somewhat narrowly focused. Several procedures for evaluation of protection materials properties to drops and steams of soman or sulphur mustard under static conditions have been performed. Detection of chemical warfare agents has been realized by using suitable chromogenic indicator. This article summarises evaluation of the realised interlaboratory comparison

The adsorption of permeating chemical compounds on the textile materials active surface is one of many principles of personal protection against dangerous chemical compounds including chemical warfare agents. The adsorption principle is generally known. However, its effective application especially in connection with the enhancing protection efficacy follows certain significant rules. A development of new textile materials based on the application of adsorbents in the combination with nanofibrous materials is the main topic of contemporary research in this area. This contribution sums up the theoretical basis of adsorption-based protective efficacy and also brings new experimental results of sorption and permeation of live CWA agents and their simulants through different samples of layered composite materials. Results are related to the basic structural parameters of nanotextiles and applied adsorbents.
