According to this requirements of GOST Р 22.9.09-2005 adopted in July, 1st, 2005, are, in our opinion, more rationalistic and meeting real needs. First, this document lists DCS needed to provide protection of respiratory apparatus not only on fires but also in cases of man-caused disasters. Second, the standard assumes PSERA with different protective properties: 1st,2nd,3rd classes of protection /2/. In other words, between products with the maximal protective characteristics (SPI-20, GDZK) and fabric bandages according to this document there should be set PSERA with intermediate levels of protective properties. At such approach the consumer has an opportunity to choose those products that have full meeting of his/her needs.

Presence of the wide range of the self-rescuers differing under protective characteristics, to weight and dimensions, convenience of using and the price, will undoubtedly lead, on the one hand, to growth of number of manufacturers of these items, on another - to more flexible satisfaction of inquiries of consumers, and finally - to real increase of a level of chemical safety of the population of the Russian Federation. Thus the goal of corresponding departments consists of proving and regulating recommendations where and in what situations it is enough to use a face bandage and where products of this or that class of protection are necessary. The problem of gradation of objects and situations by levels of their danger and definition of necessary and sufficient levels of protection is complex and demands efforts of many experts and organizations. It is much easier to establish for all of them unified maximum level of protection as it is made in /1/, or to recommend absolutely opposite - the elementary and improvised means with abysmal protective properties /3/. Such simplified approach can be only a brake on the way of "provision of the population with portable personal safety equipment of respiratory apparatus in order to reduce risk of chemical and biological contaminations at man-caused and natural disasters, terrorist actions" /4/.

In summary on the first question it is necessary to notice that putting self-rescuers for the population into the separate class of PSERA is not end in itself but should lead to development of legal documents concerning the maintenance and structured system of self-rescuers, requirements to this system and its separate elements, standards and order of use of each product from the general system of equipment.
