Terms of use
In accordance with the current legislation of the Russian Federation and the standards established on the territory of our country, personal protective equipment must be issued to the following categories of workers:
- foremen and foremen performing the duties of a foreman;
- any construction and production workers whose duties in one way or another involve the risk of injury.
If an employee at the enterprise combines several specialties at once or performs various functions, he is equipped with personal protective equipment provided for each of these professions.
We draw your attention to the fact that any ZFO has its own operational period, it starts counting from the moment of their actual issue. The duration of this period is established by a decree of the Ministry of Labor of the Russian Federation and current industry standards and depends on the type of work performed.
The period of wearing workwear also includes the period of storage of winter clothing in a warm season.
Overview of types and classes of protection of workwear
There are several types and classes of protective clothing, depending on the type of threats.
Thermal - assumes protection from high temperatures, such a ZFO is especially relevant for welders and metallurgists. Commonly used in this area are overalls made of fire-resistant materials that cover the entire body of the worker.
Overalls can be like this:
Signal. Such ammunition is used by traffic police officers, as well as representatives of road services. Reflective stripes are the main element of such workwear, thanks to which maximum visibility is ensured in the dark.
Peculiarities
The ZFO was originally developed to protect employees of industrial and construction professions, whose work duties are fraught with danger to health and life.
- Loose fit - overalls, trousers and jackets should not restrict movement, an employee, performing his job duties, should not feel discomfort.
- Functionality - protective clothing can be additionally equipped with straps, carabiners, patch or built-in pockets to improve ergonomics.
- Good physical characteristics - the ZFO should be easy to clean, have dirt-repellent properties and not get wet in the rain.
- Thermal conductivity - when working in winter, the fabric should protect a person from heat loss, and in the summer it should absorb and remove all excess moisture, while maintaining full air exchange.
- Durability - any workwear should be sewn from durable materials that will protect the employee from minor injuries and mechanical damage.
- Unlike everyday clothes, overalls are sewn in such a way that one identical suit can be worn by two people of different builds, so visually they are usually “oversized”.
The main categories of the Western Federal District include the following.
Jumpsuits, jackets and trousers - they can be used both indoors and outdoors. Winter models are available from insulated materials, as well as options from lightweight fabrics.

Main conclusions
The classification of personal protective equipment is a very voluminous topic, since each group includes a number of subgroups, but knowing its industry, it is necessary to determine the degree of exposure to harmful substances on the human body and, based on this, begin the selection.
It is not advisable to reduce the level of protection of personal protective equipment, because during the production of hazardous work, a negative impact can lead to the development of occupational diseases, injuries or deaths.
And the use of protective equipment should provide the employee with the necessary protection and be safe in itself, and the latter is confirmed by the passage of mandatory certification TR CU 019/2011.
I wish you safe and efficient work!
