This article discusses the problem of classification and features of the use of urgent instruments of crisis management of enterprises. As a result of this research, the article provides a classification of such tools on a number of classification criteria: existing (source of origin, place in the management system, cost, the scale of changes envisaged in respect of the object, orientation, types of activities addressed by the tools, the conditions of formation and use, key objectives, coverage, subjective composition of the executors) and new (content, level of novelty for the business environment, the level of individualization for the enterprise, the level of formalization of the tool). Developed classification of urgent crisis management tools deepens understanding of such tools, provides their integrity, as well as specifies processes and driving forces of elimination or reduction of negative influence of crisis phenomena on economic situation of enterprise and provision of its further effective development.
