Selected cellulosic materials and their flammability from view of normalized method by oxygen index

Fire safety solutions are applied practically in each building structure (e.g. in technological and industrial structures, and other ones, too). It is caused by legislation in force with the goal to ensure sufficient protection level against fires, and protection of health and lives of people, property protection and the last, but not the least, environmental protection. Increasing level of fire safety level can be reached by application of selected fire-protecting elements, systems, and devices and by these means to minimize danger and probability of fire origin, fire extent and consequences. In a technology of cellulose products based on tissue paper, lots of flammable substances and materials are presented. In a technological production process of tissue products - hygienic toilet paper, hygienic napkins and handkerchiefs, the strong bleaching and oxidizing substance - hydrogen peroxide that in a contact with certain organic substances supports the burming process, is substituted by more suitable and in terms of fire safety more safe substance - the enzyme. Experimental investigation is oriented on verification and comparation of bleaching substances (hydrogen peroxide and an enzyme) effect on flammability of cellulose based materials. Subject of test are samples of input materials of tissue paper production - separated waste paper, pulp and intermediary products. The article is focused on determinatrion and comparation of oxygen index of cellulose materials using the standardized method STN EN ISO 4589-1:2001. Part 1. Plastics. Determination of burning behaviour by oxygen index. Experimental flammability determination of cellulose-based products contributes to new knowledge that can be utilized in practice for increasing fire safety in technologies of processing and production thereof as well as in other building structures (e.g. storage halls and others). Knowledge of fire and technical characteristics of input raw materials, intermediary products, auxiliary substances as well as output products enables, together with designs and carrying out effective preventive and fire safe measures, to minimize danger and risk of fires origin.
