GN 2.2.5.1313-03 PDF

Full title and description

GN 2.2.5.1313-03 — "Предельно допустимые концентрации (ПДК) вредных веществ в воздухе рабочей зоны" (Maximum allowable concentrations (MAC) / Permissible exposure limits of hazardous substances in workplace air). This hygienic standard establishes PDK (MAC) values, hazard classes and related guidance for assessing and controlling airborne chemical exposures in occupational settings within the Russian Federation.

Abstract

GN 2.2.5.1313-03 is a comprehensive regulatory table and methodology for maximum allowable concentrations of hundreds of chemical substances in the air of working zones. It defines limit values (shift-average and instantaneous), hazard classification for substances, general principles for applying PDKs in industry, and forms the basis for workplace air monitoring, risk assessment and occupational hygiene controls in Russia. The document has been supplemented by a sequence of official additions (amendments) since its approval in 2003.

General information

• Status: In force as a base hygienic standard with multiple official supplements / amendments (remains the principal PDK reference with later additions published).
• Publication date: Approved 27 April 2003; entered into force 15 June 2003 (registered in the Ministry of Justice 19 May 2003, registration No. 4568).
• Publisher: Approved by the Chief State Sanitary Doctor of the Russian Federation (Ministry of Health framework); commonly distributed via Standards Publishing House / official regulatory repositories.
• ICS / categories: 13.100 Occupational safety. Industrial hygiene; related to 13.040 Air quality (ICS classification for occupational exposure and air quality management).
• Edition / version: Original GN 2.2.5.1313-03 (2003) with official supplements (examples: GN 2.2.5.1827-03 — Addendum No.1, and later additions such as GN 2.2.5.2439-09, GN 2.2.5.2730-10).
• Number of pages: Published editions available from official and commercial distributors list the work in the range commonly cited as ~161 pages in standard print distribution (cataloguing varies by vendor/format).

Scope

The standard sets hygienic normative values (PDKs/MACs) for harmful chemical substances present in the air of the working zone, specifying concentration limits for different exposure scenarios, classification of substances by hazard class, instructions for applying PDK values in workplaces (including aggregate state and predominant exposure forms), and guidance used by sanitary authorities, occupational hygienists and employers to assess compliance and to plan exposure controls. It covers industrial and occupational environments across sectors and is applicable to routine eight‑hour shift exposures and exceptional (short‑term) limits.

Key topics and requirements

• Tabulated PDK (MAC) values for a large list of chemical substances with CAS identifiers and units (mg/m3) for working‑zone air.
• Definitions of exposure metrics (average shift, short‑term/instantaneous values) and hazard class assignment for each substance.
• Procedures and rules for application of PDKs in mixed exposures and for aggregate states (gas, vapor, dust, aerosol).
• Requirements for monitoring, recordkeeping and employer responsibility for ensuring compliance with PDKs through engineering controls, administrative measures and PPE.
• Mechanism for official updates: the standard is maintained by issuing numbered additions (supplements) that add new substances or revise values.

Typical use and users

Primary users: occupational hygienists, industrial safety specialists, environmental health and safety (EHS) managers, regulatory inspectors, laboratory analysts, plant managers and consultants working in Russian industry or on projects governed by Russian sanitary legislation. Typical uses include selecting control measures, setting monitoring programs, interpreting workplace sampling results, regulatory compliance checks and health risk assessment.

FAQ

Q: What is this standard?

A: GN 2.2.5.1313-03 is a Russian hygienic standard that establishes maximum allowable concentrations (PDK / MAC) for hazardous chemical substances in the air of the working zone and provides the normative basis for occupational air quality and exposure control in workplaces.

Q: What does it cover?

A: It covers tabulated PDK/MAC values for many substances, exposure metrics (shift/short‑term), hazard class assignments, rules for applying the limits (including mixed exposures and aggregate state considerations), and is used for monitoring, compliance and control planning. The document is issued with official additions that expand or amend substance lists and values.

Q: Who typically uses it?

A: Occupational hygienists, EHS professionals, employers and regulatory authorities operating under Russian sanitary legislation, plus analytical laboratories and consultants who perform workplace measurements and compliance assessments.

Q: Is it current or superseded?

A: The original GN 2.2.5.1313-03 was approved in 2003 and entered into force on 15 June 2003; it remains a foundational PDK reference but has been issued with multiple official additions and updates (numbered supplements published in subsequent years). Users should consult the latest official supplements and regulatory bulletins to ensure they apply the current values.

Q: Is it part of a series?

A: Yes — GN hygienic normative documents form a series of related standards addressing PDKs, OBUV (orientational safe exposure levels), PDU for surfaces and other environmental/hygienic limits; GN 2.2.5.1313-03 is the central table for workplace air and is linked to other GN documents and sectoral GOSTs.

Q: What are the key keywords?

A: PDK, MAC, workplace air, occupational exposure limit, hazardous substances, hygienic norms, GN 2.2.5.1313-03, industrial hygiene, sanitary regulation.
