Abstract. The article considers the environmental economic model of risk management and the costs associated with them. In the field of eco-friendly construction and labor safety, it is customary to allocate occupational hazards and hazards, expressed by quantitative or qualitative parameters of occupational risk. Risk management or environmental risk means the recognition and analysis of risks, the development and implementation of management decisions to reduce the likelihood of adverse situations, as well as the possible reduction of material or other losses. Risk management helps to get out of the zone of uncertainty into a situation with more or less predictable results. The methodology for applying the environmental economic model under consideration is a cyclic order of performing interrelated practical actions known as the Deming-Shewhart cycle, which is inextricably linked to the process approach and the quality management system. Synthesis of the principles of the quality management system and mechanisms for managing environmental risks and costs ensures high adaptability to any external and internal stress situations, reveals professional risks in a timely manner, optimizes processes and, as a result, reduces costs.

Abstract. Extinguishing fires of petroleum products during emergency spill at industrial facilities of capital construction, transport, gas stations and the destruction of oil tanks is most effective when using foamers. Classification of foaming agents intended for extinguishing of fires of oil products, which is based on the structure of spreading coefficient of water foam-forming solution over hydrocarbon surface is presented. Results of experimental studies using various foaming agents with different structure of spreading coefficient are given. It is determined which of homologs of a number of sodium primary alkylsulfates differ in foaming capacity and fire extinguishing efficiency. It is revealed that decrease of interfacial tension value leads to reduction of extinguishing time of a heptane flame.
