MR 2.2.7.2129-06 PDF

Full title and description

MR 2.2.7.2129-06 — "Work and rest schedule of working people during the cold season outdoors or in unheated rooms" (Методические рекомендации). Provides recommended regimes of work and rest, exposure limits and practical guidance for organizing safe labour in cold outdoor conditions or in unheated premises.

Abstract

This methodological recommendation sets out criteria and example schedules for work and rest for employees exposed to cold environments (outdoors or in unheated rooms). It includes regional zoning by climatic regions, criteria for permissible thermal state for specified exposure durations, guidance on required thermal insulation of personal protective equipment (headwear, footwear, gloves and full ensembles), and tables of equivalent temperatures to assess combined effects of low air temperature and wind.

Scope

Applies to the organization of labour for workers exposed to cold during the cold season when working in open areas or in buildings that are not heated. The document defines exposure-duration dependent limits, safe combinations of ambient temperature and wind speed, recommended scheduling of work and rest periods, and minimum thermal insulation requirements for clothing and accessories by climatic zone. It is intended to be used as a basis for local normative acts and workplace rules addressing cold-weather working conditions.

Key topics and requirements

• Criteria for permissible thermal state (lower limits) for cold exposure with different maximum durations (e.g., up to one hour, up to three hours) and corresponding safety thresholds.
• Recommended schedules of work and rest (time-in-cold vs. recovery periods) by temperature/wind combinations and type/intensity of work.
• Regional climatic zoning scheme to adapt recommendations to different parts of the Russian Federation.
• Requirements for thermal insulation of personal protective equipment and clothing ensembles (headwear, footwear, gloves, full sets) by climatic zone.
• Tables of equivalent temperatures to assess the combined effect of air temperature and wind on exposed body parts.

Typical use and users

Used by occupational health and safety specialists, industrial hygienists, employers and HR managers responsible for outdoor or unheated-workplace operations, safety engineers, workplace physicians, trade unions and regulators when developing local rules, shift schedules and protective clothing specifications for cold-weather work.

Related standards

Related national and international documents include other MR 2.2.7 series guidance on physiology and ergonomics, GOST/GOST R documents on protective clothing and cold stress, and international guidance such as ISO 11079 (Ergonomics of the thermal environment — determination and interpretation of cold stress when using required clothing insulation — IREQ).
