In all the processes carried out by a person as a result of life, there is the risk of threats to the environment and human life and health.
This is known as a potential danger.
The potential hazard - the likelihood of human exposure to harmful and life-threatening factors that could cause injury, sudden and drastic violations of health.
Characteristics of the potential danger
The potential danger - it is universalHuman interaction with the environment property and its components. Her character changes from natural and natural factors of human life to all kinds of negative anthropogenic factors, often associated with scientific and technical progress (electricity, all kinds of radiation, high and low temperature, power grid).
Work environment is complemented by morepowerful technology and technical systems that facilitate human labor, making it more productive, and in some cases eliminate the need altogether without human intervention. However, the more high-tech environment with which people interact, the greater the potential danger for him. All production processes are potentially dangerous to health and can cause death of a person.
The potential danger and risk
The probability of the potential hazard can be assessedby risk. In practice, complete security is unattainable as long as there is a source of danger. However, you can reduce the risk of danger to a minimum, ensuring maximum safety. As a consequence, the risk of a long period of time remains unfulfilled or may occur in the form of an accident.
The main characteristic of the level of security -the permissible (residual) risk to humans. Using various statistical data, it is possible to pre-evaluate the risk in the various spheres of human activity. For example, the risk of suffering in a car accident can be characterized as follows: for 1 year of 10 people at risk to get into a car accident.
Acceptable risk is established practice inaccording to the reached in the most prosperous similar systems' technical system - a man. " For example, the probability of a severe accident, nuclear power must not exceed 10 (10 for 1 reaktorogod). Acceptable risk is necessary to provide a set of necessary activities (technological, technical, organizational), that will minimize the likelihood of danger.
