experience. The minimum value of Cf observed at the age of 33 years and thereafter
slightly increased.
2. Time. Most injuries observed between 3 and 5 o'clock in the morning - it's
hard to focus. After a weekend rate of injury increases slightly

3. Gender. The frequency of injuries in women is less than in men.

 Topographical method

This method is based on the fact that on the map of the enterprise (the
company) should be marked the place where the accident occurred. This allows you
to clearly see the places with high risk, requiring careful examinations and preventive
measures.

 Monographic method

It consists of detailed research of production equipment, production
environment to identify hazardous and harmful factors that can lead to accidents. In
this case, the team conducts medical exams, analyze the technical condition of
equipment, analyze of industrial hygiene, etc.

The probability of accidents is determined by mathematical statistics, where
the hazard is rated by category:
1) probable;
2) possible;
3) unlikely.
This method can detect not only the causes of accidents but also, more
importantly, helps identify potential dangers and hazards that can affect the people.
This method can also be used to develop measures of occupational labour for
manufactures (enterprises), which is only projected.

 Economic methods

The economic method is based on determining the economic damage caused
by accidents. This method is aimed to clarify the economic efficiency costs of
development and implementation measures of occupational health and safety.
Material costs are determined by the formula:

M = P + E + S
where P - the cost of production due to accidents;
E - economic costs (for the development and implementation of measures to
prevent accidents, occupational diseases);
S - the social costs (for the victims) in accordance with the collective
agreement.

 Technical method
