GOST 12.2.056-81 PDF

Full title and description

GOST 12.2.056-81 — Система стандартов безопасности труда. Электровозы и тепловозы колеи 1520 мм. Требования безопасности. (English: Occupational safety standards system. Electric and diesel locomotives for 1520 mm gauge. Safety requirements.)

Abstract

Interstate (originally USSR) safety standard that sets mandatory design and ergonomic safety requirements for electric and diesel locomotives built for the 1520 mm (Russian broad) gauge. The standard addresses hazards to locomotive crews and maintenance personnel and covers cab layout and equipment, access, platforms, handholds, seating, placement of major pressure and battery systems, thermal and acoustic conditions in the cab, and provisions to ensure safe operation, maintenance and repair of newly designed locomotives (and, by agreement, some newly manufactured units).

General information

• Status: Active / in force (applied as an interstate standard with subsequent amendments; parts have been updated or replaced by later GOSTs in specific measurement methods).
• Publication date: Approved 27 May 1981 (Gosstandart USSR decision); commonly listed with a publication/effective date 01 January 1983 in commercial catalogues and reprints.
• Publisher: Approved by the USSR State Committee for Standards / issued as an interstate (MGS) standard (now maintained in national/eaeu libraries and databases).
• ICS / categories: Railway engineering / rolling stock (ICS 45 — Railway engineering; relevant subgroup: 45.060 Railway rolling stock) and labour safety/occupational safety classification used in the GOST SSBT system.
• Edition / version: Original designation ГОСТ 12.2.056-81 with amendments (Amendments Nos. 1, 2, 3 and later editorial/technical changes). Some annex measurement methods were later replaced by newer GOSTs (see Related standards). A reissue/republishing is recorded (2002 reprint).
• Number of pages: 27 pages (typical published PDF and print copies).

Scope

GOST 12.2.056-81 establishes safety requirements for the design and arrangement of electric and diesel locomotives for 1520 mm track gauge. It applies primarily to newly designed locomotives and, where agreed between manufacturer and customer, to units being manufactured. The standard excludes in-service (already operated) locomotives, specialized traction units intended for industrial or special technological transport, and certain export-dedicated designs unless specifically referenced. Several annexes specify measurement methods for cabin microclimate, noise and vibration and test procedures; some of those measurement methods have been later superseded by separate GOSTs.

Key topics and requirements

• General safety of design — protection of locomotive crews from hazardous and harmful production factors and provision of safe access for operation, maintenance and repair.
• Cab ergonomics and crew workplace — detailed requirements for driver’s seat dimensions, adjustability, seating angles, armrests and instructor seats; layout to ensure visibility and control accessibility.
• Placement and exclusion zones — requirement that main air reservoirs and batteries be installed outside the driver’s cab (not under the cab floor or above the ceiling).
• Platforms, steps, handrails and inter-section passages — minimum widths, heights and guarding provisions for safe crew movement and inspection walks.
• Thermal, acoustic and vibration conditions in the cab — limits and measurement-method requirements for microclimate, noise and whole-body vibration; note that methods in specific annexes were later replaced by newer standards.
• Lighting, signaling, external audible and visible warnings — requirements to ensure visibility, safe coupling and shunting operations.
• Maintenance and servicing access — safe and convenient access to major aggregates and components to reduce risk during servicing and repair.
• Protective measures and guards — requirements for enclosures, shields and protective devices to prevent contact with moving or energized parts, in line with the SSBT system of labour safety standards.

Typical use and users

Primary users are locomotive designers and manufacturers, railway operators, technical safety and ergonomics engineers, certification and conformity assessment bodies, and national/regional standards organizations in countries applying CIS/EAEU GOST standards. The standard is used to define design checklists, acceptance criteria for new locomotive builds, and to inform workplace safety documentation for crews and maintenance personnel.

Related standards

GOST 12.2.056-81 cross-references and has been used alongside other national and interstate standards for rolling stock and occupational safety. Notable related documents and later replacements (for specific measurement methods or parameters) include: GOST R 55364-2012 (general technical requirements for electric locomotives), GOST 33661-2015 (method for cabin heat-transfer coefficient — replaced that annex), GOST 33463.1-2015 and GOST 33463.2-2015 (methods for microclimate and for noise and vibration measurements in cabs), and other SSBT (GOST 12.0.xxx) series standards referenced for hazard limits and testing methods. The standard also appears in lists used when implementing TR CU / EAEU technical regulation requirements for railway rolling stock.

FAQ

Q: What is this standard?

A: It is an interstate (originally USSR) occupational safety standard that defines safety and ergonomic requirements for electric and diesel locomotives built for the 1520 mm gauge.

Q: What does it cover?

A: The standard covers design- and layout-related safety requirements for driver’s cabs and locomotive body, placement of pressure vessels and batteries, access platforms and handholds, seating and ergonomic provisions, environmental (thermal, acoustic, vibration) conditions in the cab, guarding of hazardous parts, and requirements that support safe operation, maintenance and repair. Certain annex measurement methods (noise, vibration, cabin heat transfer, microclimate) have been updated or moved to later GOSTs.

Q: Who typically uses it?

A: Locomotive designers and manufacturers, railway operators, safety and ergonomics engineers, conformity and certification bodies, and standards/Regulatory authorities in countries that apply CIS/EAEU GOST documents.

Q: Is it current or superseded?

A: The core standard (designation ГОСТ 12.2.056-81) remains an authorized interstate labour-safety standard, but specific annexes and measurement-methods have been superseded by later GOSTs (for example methods for cabin heat-transfer, microclimate, noise and vibration). Users should check the latest national/eaeu normative indices to confirm which parts are current for regulatory or contractual use.

Q: Is it part of a series?

A: Yes — it is part of the GOST “Система стандартов безопасности труда” (SSBT) series of occupational safety standards (the GOST 12.x family), and it cross-references other GOSTs for measurement methods and hazard limits within the railway engineering / rolling stock group.

Q: What are the key keywords?

A: Locomotive safety, driver’s cab ergonomics, 1520 mm gauge, SSBT, noise measurement, vibration, microclimate, maintenance access, batteries and reservoirs placement.
