GOST 12.1.007-76 PDF

Full title and description

GOST 12.1.007-76 — "Система стандартов безопасности труда. Вредные вещества. Классификация и общие требования безопасности" / "Occupational safety standards system. Noxious substances. Classification and general safety requirements". The standard establishes a classification of harmful (noxious) chemical substances by degree of hazard and sets general safety, sanitary and organizational requirements for their production, use, storage, control and neutralization in industrial environments.

Abstract

GOST 12.1.007-76 defines terms and a four-class hazard classification for noxious substances, specifies basic preventive and protective measures for workplaces where such substances occur, and sets general requirements for technological design, ventilation and sanitation, air monitoring, labeling/documentation, decontamination and medical surveillance of personnel. It applies to harmful substances present in raw materials, products, intermediates and production wastes, and excludes radioactive and complex biological agents.

General information

• Status: Active / generally applied as a national/interstate occupational-safety standard (originally USSR standard; retained in collections and national practice, see national standards bodies for country-specific legal standing)
• Publication date: Approved 10 March 1976; introduced 1 January 1977 (often cited as GOST. .-76).
• Publisher: Approved by the State Committee for Standards of the Council of Ministers of the USSR (Gosstandart USSR); maintained / reissued in later compilations by national standards bodies (e.g., Rosstandart / interstate standards bodies).
• ICS / categories: 13.100; 13.300 (occupational safety / protection against dangerous goods and related safety categories).
• Edition / version: Original designation GOST 12.1.007-76 with Amendments No.1 (Sept. 1981) and No.2 (Mar. 1989); reissues and reprints have appeared (notably reissues/compilations in the 1990s and 2000s).
• Number of pages: Typically 7 pages (varies by reprint/format; some commercial copies list 7–8 pages).

Scope

The standard applies to noxious chemical substances contained in raw materials, products, semi‑products and production wastes and establishes general safety requirements for their manufacture, application and storage. It does not cover radioactive substances or biological agents (complex biological systems, bacteria, microorganisms). The scope includes classification by degree of hazard, rules for limiting airborne concentrations (normative references), and general control and protective measures for workplace safety and health.

Key topics and requirements

• Classification of noxious substances into four hazard classes (extremely dangerous, highly dangerous, moderately dangerous, slightly dangerous) with examples and criteria.
• Definitions and explanatory terms related to toxicology, lethal doses/concentrations, acute and chronic action zones, and biological exposure indices.
• General safety requirements for technological processes: substitution, closed-cycle processes, automation, wet processing to reduce dust, and other engineering controls to minimize releases.
• Requirements for ventilation, capture and neutralization systems, waste handling, recovery and disposal to prevent excess release into workplace air.
• Sanitary limitations and references to permissible (limit) concentrations in workplace air and methods for air monitoring and control (links to related workplace air standards).
• Organizational measures: labeling and documentation, work instructions, training and medical surveillance (pre‑employment and periodic examinations) for workers exposed to noxious substances.
• Personal protective equipment and emergency/first‑aid measures, including decontamination and neutralization procedures for vessels and equipment that contain hazardous classes 1–4 substances.

Typical use and users

Used by occupational health and safety specialists, industrial hygienists, process and plant engineers, chemical manufacturers, environmental and safety compliance officers, regulatory inspectors and designers of ventilation/containment systems. It is a reference for establishing workplace safety policies, drafting local safety instructions, and for inclusion in technical specifications and permits where GOST standards are applicable.

Related standards

Commonly referenced in conjunction with other SSBТ/GOST documents such as GOST 12.1.005 (air of the working zone — permissible concentrations and measurement), GOST 12.0.003 (dangerous and harmful production factors), and related occupational-safety and chemical‑hazard standards (ventilation, sampling and measurement methods, protective equipment and fire/explosion safety standards). National and sectoral rules and sanitary regulations also cross‑reference this standard.

FAQ

Q: What is this standard?

A: GOST 12.1.007-76 is an occupational‑safety standard that classifies harmful (noxious) chemical substances by hazard degree and sets general safety, sanitary and organizational requirements for their production, use, storage and control in industrial settings.

Q: What does it cover?

A: It covers terminology, a four‑class hazard classification (from extremely dangerous to slightly dangerous), basic safety and engineering controls, requirements for ventilation and capture systems, sanitary limits for workplace air (by cross-reference), monitoring and measurement principles, labeling/documentation, protective equipment and medical surveillance measures. It excludes radioactive and biological agents.

Q: Who typically uses it?

A: Occupational health & safety officers, industrial hygienists, plant/process engineers, regulatory bodies, inspectors, environmental/safety consultants and manufacturers in industries handling hazardous chemicals.

Q: Is it current or superseded?

A: The standard was approved in 1976 and introduced 1 January 1977; it has been maintained in later reissues and amended texts and continues to appear in national/intrastate compilations and references. National legal applicability or whether a newer national regulation supersedes it depends on the country and the national standards/regulatory authority—consult the relevant national standards body or regulator for definitive current legal status in your jurisdiction.

Q: Is it part of a series?

A: Yes — it is part of the SSBТ (System of Standards for Labour Safety / occupational safety standards) series (GOST 12.0.xxx and GOST 12.1.xxx families). It is intended to be used together with more specific GOSTs on workplace air measurements, protective equipment, fire/explosion safety and other sectoral safety standards.

Q: What are the key keywords?

A: harmful/noxious substances; hazard classification; workplace air; permissible concentration; industrial hygiene; occupational safety; decontamination; ventilation; GOST.
