Chlorinated hydrocarbons are very often used and are relatively dangerous substances from healthy risk point of view. While manipulating with them, mainly in large volumes, individual protective equipment (IPE) must be used in a protection position. Users are supposed to know the construction material breakthrough time especially in case of long-term usage of personal IPE and in the situation when contamination of them is real. Studying connections between a chemical compound structure and the structure of IPE characterised by barrier materials enables us to understand present body protective devices protection quality and gives us an option to choose barrier materials with targeted properties. In this article there are results of breakthrough time of isolating protection folio with a butyl rubber barrier layer in relation to chlorinated ethanes. This material is used for protection of specialists of both Fire Rescue Brigades and the Czech Armed Forces Chemical Corps. The PIEZOTEST device has been used for detection of permeated chemicals. The Quartz Crystal Microbalance (QCM) sensor is a part of PIEZOTEST device.
