These methods should be used comprehensively.

For statistical method risk is calculated by the formula:

whereR – the risk for the certain period of the time,

n – number of actual manifestations of risk (injuries, accidents, disasters)

N – theoretically possible number of dangers to this type of activity or object

EXAMPLE. In 1998 in Ukraine died in the domestic sphere 68,271 people. In production died 1550 people and injured - 47,530 people.

The total population as of 1998 - 50.1 million people are employed - 14.8057 million people.

The risk of fatal injuries in the home: Rdt. home. = 68271/50100000 = 1363 * .

The risk of fatal injury at work: Rdt.work. = 1550/14805700 = 104.7 * .

The risk of injury in the workplace: Rtr.wrkp. = 47530/14805700 = 3210 * .

Acceptable risk -the risk is normalized in the world ( .).

Acceptable risk - is a compromise between the level of security and the ability to achieve it.

Safety -a condition in which a certain probability (risk) is excluded realization of the potential dangers.

Providing the safety - a complex process, which can be divided into elementary components, assumptions, ideas, called principles.

Legal principles –fixed by the law rules that provide an acceptable level of safety.

Orienting principles - the fundamental ideas that define the search direction sound decisions and serve as a methodological and information base.

Technical principlesaimed at preventing the direct action of hazards and are based on the use of physical laws.

Managerial called principles governing the relationship and the relationship between the individual stages and phases of process safety. These include: planovist, control, management, feedback, staffing, responsibility.

Organizationalare the principles by which implemented the provisions involving science-based solutions. This incompatibility principles, ergonomics, rational organization of work and rest, compensation and others.

Conclusion.

- Identification of dangers - dangers identification with their quantitative characteristics and coordinates.

- Predictions manifestation dangers based on the theory of probability and statistics.

- Achieving an acceptable level of manifestation dangers.

- The prevention and elimination of negative incidents.

- Development and systematization of rules of life and activity.

Deep study, comprehensive investigation manifestation dangers detailed risk analysis and implementation of rules and regulations can reduce the negative impact on human system "man - machine - environment" and reduce security risks to an acceptable level.
