In the presence of small sources of fire (smoldering cigarette butts, matches, a short circuit in the electrical, etc.) fire wood and fire spread in protected structures is not happening. The deep impregnation of wood, carried out in the impregnating cylinder under pressure and hot-cold baths, provides good protection from fire. In this case, impregnated with fire retardant wood, regardless of the source of the fire is not ignited, but only a char and not able to spread the fire. The mechanism of protection from fire retardants has not been studied in detail. It is known that at high temperatures, depending on the type of flame retardant may occur following physical changes: a flame retardant melts at a temperature below the point fire wood to form a glaze that covers it and the connection with the oxygen of the air, fire-resistant substance decomposes under the influence of high temperatures, highlighting the large amount of inert gases, these gases reduce the relative content of volatile pyrolysis products from the wood surface, because of this hot mixture is not ignited, in the process of melting and evaporation retardant consume a large amount of heat in result, the temperature of the surface layers of the timber does not reach the limit values, at which its ignition, flame retardant material, located on the wood surface, which hinders access of oxygen to the source .Produkty decomposition of wood, in violation of a protective film, the pressure released to the environment and burn at some distance from her and because of this fire Wood is not happening. Based on these provisions, the best flame retardants are substances that are under the influence of high temperatures decompose with the release of inert gases and form a protective film on the surface timber. For example, ammonium phosphate when heated allocates ammonia, which does not support burning wood, and phosphoric acids, covering the wood (or coal) with a protective film.

Fire resistance of building structures characterized by a time during which a fire they are capable of withstanding the required loads without being destroyed. Unprotected wooden structures have a relatively high fire resistance, 20-70 minutes. But big disadvantage of wooden structures in the fact that they are able to further the spread of fire and can serve themselves a source of fire. As a result, the protective treatment of wood fire-retardant wood designs can be improved by 3-4 times. In this case, flame retardants impregnated wood, exposed to fire, slowly smolders without letting the flame, after removing the source of fire wood is quickly extinguished.

Intelligent Enterprise system, is a system of organization whose purpose is to achieve the full and continuous satisfaction of the present and future needs of the customer, through the consolidation of the added value and creating new value, by its collaborators and leaders, in the substantive activities of the company, using his intellect and his art; Thus, the economic continuity of the Organization, and providing human capital to the country. Among its multiple aspects of benefit, is the de re-alfabetizar functionally their activities to persons of the company or organisation concerned. Autocatalytic autocatalytic learning learning is phases above in the evolution of the learning of persons, laque generated their own knowledge. That is, after going through learning obtained in previous phases, that start with the traditional training where the teacher explains and the student listens, continuing with other types of teaching and learning in which gradually the person arrives to learn on their own, although in a very basic way, and then lies on the autocatalytic. This concept is described to details in the book intelligent enterprise system, a proposal to the world about how should be the company was of the knowledge (2005), by Anibal Basurto Amparano, Editorial company smart, Mexico; and hence exposes how it evolves the generation and transmission of knowledge, i.e. in the following phases of the learning of persons: 1st. The traditional courses, 2nd.

Ubiquitous courses, 3rd.Hard self-learning, 4th.Directed interactive self-learning, 5th.Auto-catalitico learning, 6th. Constructivist learning and 7th. Constructivist work. In the intelligent enterprise system, the above-mentioned phases are developed through the Ateneo, which is defined as: powerful school of learning and self-learning, whose ultimate goal is that the person learn to work and work learning in place of work, managing to generate, to structure and disseminate useful knowledge for the achievement of the mission and vision of the organization. The impulse to autocatalytic learning, is suitable for any organization, company of private or public institution, by the various benefits it generates, this is both for the Organization and for its customers or users and for staff of the same. There are cases in which the effectiveness of the aforementioned type of learning, has been tested as in the Commission Federal electricity (CFE) of Mexico, which were created technological universities specifically intended for their workers.

People who come to the stage of learning-autocatalytic, acquire the capacity to generate knowledge from reading books, and can thus write other books and came to prepare courses for the transmission of their knowledge to other people who are at earlier stages of learning. In this way, the organization in which occurs the above, encourages the creation, preservation and increase intellectual capital in the same. The book intelligent enterprise system, sets out that persons will be preparing to enter in the synthetic phase of the system which is the so-called network of microbusiness in this phase of learning.
