Mechanic repairman categories according to etc. Profession Repairman (6th category) in the Unified Tariff Qualification Directory. Unified tariff and qualification directory

Introduction

This edition of the Unified Tariff and Qualification Directory of Work and Professions of Workers (ETKS) was developed on the basis of the previously existing ETKS, issue 2, approved by Resolution of the State Committee for Labor of the USSR and the Secretariat of the All-Union Central Council of Trade Unions dated January 16, 1985 N 17/2-54. Its development was caused by changes in production technology, the increasing role and scientific and technological progress in production activities and, on the basis of this, increased requirements for the level of qualifications, general education and special training of workers, quality, and competitiveness of products in the domestic and foreign markets; as well as changes in the content of labor.

The categories of work are established according to their complexity without taking into account working conditions (with the exception of extreme cases that affect the level of complexity of work and increase the requirements for the qualifications of the performer).

The tariff and qualification characteristics of each profession have two sections. The section "Characteristics of work" contains a description of the work that the worker must be able to perform.

The “Must Know” section contains the basic requirements for the worker in terms of special knowledge, as well as knowledge of regulations, instructions and other guidance materials, methods and means that the worker must use.

The tariff and qualification characteristics provide a list of jobs that are most typical for a given category of worker’s profession. This list does not exhaust all the work that a worker can and should perform. The administration may develop and approve, in agreement with the trade union committee or other representative body authorized by employees, an additional list of works corresponding in complexity to those contained in the tariff and qualification characteristics of the professions of workers of the corresponding categories.

In addition to the work provided for in the section "Characteristics of work", the worker must perform work on the acceptance and delivery of shifts, cleaning the workplace, devices, tools, as well as maintaining them in proper condition, maintaining established technical documentation.

Along with the requirements for theoretical and practical knowledge contained in the section, the worker must know: rules and regulations on labor protection, industrial sanitation and fire safety; rules for using funds personal protection; requirements for the quality of work (services) performed; types of defects and ways to prevent and eliminate them; industrial alarm; requirements for the rational organization of labor in the workplace.

A worker of higher qualifications, in addition to the work listed in his tariff and qualification characteristics, must be able to perform work provided for by the tariff and qualification characteristics of workers of lower qualifications, as well as supervise workers of lower grades of the same profession. In this regard, the work listed in the tariff and qualification characteristics of professions of lower grades is, as a rule, not included in the characteristics of higher grades.

The general provisions of the Unified Tariff and Qualification Directory of Work and Professions of Workers are included in the ETKS,
