Abstract. This article is devoted to fireproof processing of steel structures. The main task is to consider different types of sections of rod elements and to choose the most effective section for a steel column from the point of view of fire protection. For the solution of this task the steel columns with various cross sections working in identical entry conditions were considered. All necessary calculations for all types of sections were carried out. Results of calculations were presented in the summary table according to which the comparative analysis was made. At the end of work the conclusion that the compound section from four equal corners is the most effective from the point of view of fire protection.

For the rational decision of colors on the different building objects it is recommended to use optimal colors to create the best climate at industrial enterprises. For this purpose the appropriate building codes are developed. Building constructions in the industrial enterprises, which are applied fire-retardant paint, also painted in the appropriate color with tinting paste, or applying the finishing coat with that color. It is shown, that the introduction of tinting paste in the fire-retardant paint as overcoating of the fire-retardant paint leads to chaotic effect on height of foam of the intumescing coatings. The conclusions about invalidity of coloring with the fire-retardant paints in saturated tones used tinting paste without preliminary testing on the fire retardant efficiency are made. Similar conclusions are applied to the paint systems for an intumescing fire protective coatings using surface finishing.

Abstract. The paper aims at researching fire resistance of a prototype facade system "Technocom" (type Alucobond A2). Experimental and theoretical research of fire hazard facade system is carried out. The objectives of the study are to determine compliance with the applicable front of special technical requirements. The status of problem reducing fire hazard facade system is reviewed. The method developed by compensatory measures is applied.
