Criteria and rules for choosing safe and environmentally friendly building materials
Most know that any material for the construction of residential buildings requires attentive sanitary control and the availability of appropriate certificates as confirmation of it as confirmation. Let’s try to consider what methods the safety of building materials is evaluated.
The basis of the safety of any material is the thorough normalization of all substances that make up. There are more than a hundred volatile chemical compounds in the air of each dwelling, and some of them are of a significant danger to human health. Most of these substances fall into the air precisely by discharge from building materials. So, the selection of suitable building materials requires the use of a particularly thorough approach, because they are one of the elements that form the living space of a person where he spends most of his life.
The basis of hygienic rationing is the special concept of MPC – maximum concentrations, which are permissible to the concentration of harmful substances in the air. Danger is only such an amount of substances that exceeds the MPC. The final document, which is the main one for the consumer, is recognized as a certificate or conclusion of competent experts.
A hygienic certificate should be issued by a special service that works in the field of sanitary and epidemiological supervision. There are three main types of such a certificate-an expert opinion on certain products, a certificate of hygiene for this type of activity and the conclusion of the sanitary and epidemiological service for the technical conditions of production.
