“…More recently, intumescent fire retardant coatings have been used for protection of wood and steel in buildings, chemical plants and other facilities [7][8][9]. Intumescent coatings are composed of three main fire retardant additives: (i) an acid source (such as ammonium polyphosphate, APP), which is usually a carbonized accelerator or a dehydrating agent generating acid compounds in situ; (ii) a blowing agent (such as melamine, MEL), which is an important ingredient for production of gases when heated; and (iii) a carbon source (pentaerythritol, PER), which is the char forming agent insulating the underlying substrate and maintaining structural integrity [10][11][12][13].…”

In this work, intumescent coatings were prepared for protection of wood from fire. The fire-retardant chemical ammonium polyphosphate (APP) is known to have poor resistance to water and high humidity as it is hygroscopic in nature. To improve the water resistance, durability and fire resistance of the intumescent coating, APP was modified using a hybrid organic-inorganic polysiloxane encapsulation shell prepared by the sol–gel method. The physical and chemical properties of the intumescent mix containing microencapsulated ammonium polyphosphate (EAPP) particles were characterized by X-ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), water absorption, dynamic vapor sorption (DVS) and thermogravimetric analysis (TGA). The EAPP mix showed 50% reduction in water absorption, 75% reduction in water vapor sorption and increased thermal stability when compared to the APP mix. The intumescent coatings were applied on wood samples, and their fire performance was evaluated using a cone calorimeter test. The intumescent coatings containing EAPP mix showed better fire retarding properties with longer time to ignition, lower heat release rate and shorter heat release peak when compared to the coating without EAPP mix. The prepared intumescent coating shows higher resistance to water and moisture, and it has great potential to be used in bio-based construction industry for enhancing the fire resistance of wood.

“…The basis of the terminological system presented in the article was formed by the concepts widely used in the field of fire protection, to which, in order to give the system a clear structure and logical completeness, new ones were added (constructive method of fire protection, combined method of fire protection [5][6][7]). As a way of combining the concepts that make up the conceptual field, we used relations similar to those established in the classification of fire protection means by composition and properties.…”

The paper considers a variant of combining the terms used in the field related to the study of fire protection means into a terminological system. The correct definition of terms is also crucial in technological and manufacturing processes. That is why it was decided to form and describe the terminological system in the field of fire protection and fire retardant materials. The terms in terminological system are to be related between each other, and to be expressing the relationship between the concepts that they denote. Such a system does not yet exist in the field of fire protection, so the authors aim was to create its basis. The types of relations between the terms defining the structure of the system have been established, a diagram that illustrates the distribution and coordination of terms in the system has been developed. On the basis of the relations between the terms established in the terminological system, the existing definitions were assessed with subsequent, if necessary, adjustments to meet the requirements for the terms of unambiguity, compliance with the expressed concept and elimination of synonymy.

“…The fire protection of process units used in the upstream and midstream production and shipping of oil, natural gas, and petroleum products and the protection of bearing structures of road and railroad tunnels and bridges have recently become increasingly urgent. A fire occurring in a tunnel or under a bridge involving a burning vehicle carrying petroleum products, or a fire on an offshore platform, or at an oil and gas asset to be protected, entails severe local fire impact on the bearing structure and is most often described using a hydrocarbon fire curve [1][2][3][4][5][6], as stipulated in EN 1363-2:1999 [7] (Figure 1). One of the crucial design indicators defining the fire safety assurance level for buildings and facilities is the structural fire resistance rating, i.e., the time since the fire impact starts (minutes, standard testing conditions) or the calculated time period until either one or a sequence of limit state indicators are reached (R, E, I) [8].…”

In a situation where a fire occurs either in a tunnel with a burning vehicle carrying petroleum products, at an offshore platform, or at an oil and gas asset to be protected, such a case is commonly described using a hydrocarbon fire curve. Therefore, it is extremely important to design construction, which can maintain stability and bearing capacity both under the standard and hydrocarbon fire modes. The purpose in this work is to hold a behavior simulation of a steel structure with fireproofing ensured through lightweight concrete slabs reinforced with fiber glass as well as a validation of the outcomes by assessing the experimental findings obtained from the relevant fire tests. A fire resistance study was carried out here for steel structures with a profile ratio of 156 mm−1 for the cases of a standard fire and of a hydrocarbon fire. A constant static load of 687 kN (70 tf) was taken for standard fire and 294 kN (30 tf) for hydrocarbon fire; the column was under vertical compression with one end resting on a hinged support and the other end rigidly fixed. The specimen design incorporated single-layer box-section cladding made of Pyro-Safe Aestuver T slabs, 40 mm thick and of a 650 kg/m3 density, pre-cut to fit the column size. The column strength loss (R) ultimately occurred after 240 min in the standard fire case and after 180 min in the hydrocarbon fire case. As the breach in the fireproofing structural integrity (E) or the installation accuracy cannot be considered, the limit state indicators may show certain discrepancies. According to the simulation performed using SOFiSTiK software, the design fire resistance rating of the structure in a hydrocarbon fire case was 58% higher than the figure obtained by holding fire tests due to the slabs cracking during the experiment session; the discrepancy between the outcomes of the session and the simulation in a standard fire case was as much as 15%.
