TU-GAS-86 PDF

Full title and description

TU-GAS-86 — «Требования к установке сигнализаторов и газоанализаторов» (Requirements for installation of gas detectors and gas analyzers). The document sets mandatory technical requirements and practical rules for siting, selecting and interfacing stationary continuous gas detectors, alarm systems and sample‑taking arrangements for combustible and hazardous gases and vapors in industrial premises and open installations (primarily for oil, gas and petrochemical facilities).

Abstract

TU-GAS-86 is a 1986 technical specification issued for the oil‑refining and petrochemical sector that defines how to install stationary gas signal detectors and quantitative gas analyzers for both explosive (over‑limit combustible) and hygienic (maximum allowable concentration) monitoring. It covers detector categories for explosive zones, recommended sensor locations and heights, spacing and sampling arrangements, alarm actions (visual/acoustic and automatic protective actions), and includes illustrative appendices with layout examples and measurement units.

General information

• Status: Historically approved technical requirements for the oil/gas sector; referenced and offered in standards/databases for use, though not necessarily included in current mandatory national lists in all jurisdictions.
• Publication date: Approved 30 April 1986; came into force 1 January 1987.
• Publisher: Approved by the Ministry of Oil Refining and Petrochemical Industry of the USSR (Миннефтехимпром СССР).
• ICS / categories: Oil and gas equipment / instrumentation and safety for petroleum and petrochemical facilities (industry classification entries in vendor/standards catalogs point to 75.180 and related oil & gas equipment classes).
• Edition / version: TU‑GAZ‑86 (original 1986 text); some commercial repositories list a variant with Change No.1 and later re‑issued scans/compilations.
• Number of pages: Commercial copies and bibliographic listings show approximately 25–30 pages depending on edition/appendices.

Scope

Applies to newly designed and reconstructed facilities of the oil‑refining and petrochemical industries for the purpose of establishing the location, number and type of permanently installed continuous gas detectors (both for pre‑explosive concentrations and for hazardous substances at occupational exposure limits), placement of sampling points, alarm interfaces and automatic protective actions (for example, shutdown of equipment or activation of ventilation). The document addresses both indoor production spaces and open installations (tank farms, pump stations, loading areas) and contains specific prescriptions for mounting heights, distances, and grouping of detectors for typical storage and process configurations.

Key topics and requirements

• Definitions and classification of detector types (explosion‑limit/safety alarms vs. quantitative gas analyzers for hygienic monitoring).
• Rules for sensor placement: heights, distances, and number of detectors for rooms, pump stations, tank farms and open installations.
• Specification of detector categories and explosion‑protection groups required for hazardous zones.
• Requirements for alarm signalling (visual/acoustic) and automatic protective responses (ventilation start, equipment shutdown) tied to threshold levels.
• Sampling system and probe placement rules for gas analyzers and instructions for representative sampling points.
• Appendices with example layouts, measurement unit tables and recommended spacing diagrams for common plant configurations.

Typical use and users

Used by process and safety engineers, project designers, instrumentation and control specialists, facility operators and procurement teams in oil, gas and petrochemical industries when designing or upgrading plant gas‑detection and analyzer systems. Also used by manufacturers and integrators of gas detectors for guidance on installation practices in post‑Soviet markets or legacy facilities.

Related standards

Often used together with earlier TU‑GAZ series documents (e.g., TU‑GAZ‑75 which TU‑GAZ‑86 replaced), national fire‑safety rules and later regulatory acts governing industrial safety and explosion protection. Contemporary practice requires cross‑checking TU‑GAZ‑86 provisions against current national technical regulations, fire‑safety rules and updated industry standards before application.

FAQ

Q: What is this standard?

A: TU‑GAZ‑86 is a sector technical specification from 1986 titled «Требования к установке сигнализаторов и газоанализаторов», establishing requirements for installation and arrangement of stationary gas detectors and gas analyzers for oil, gas and petrochemical facilities.

Q: What does it cover?

A: It covers siting, sensor heights and spacing, detector categories for explosive/hazardous zones, sampling points for analyzers, alarm signalling and recommended automatic protective actions, plus illustrative appendices with layout examples.

Q: Who typically uses it?

A: Process and safety engineers, instrumentation designers, facility operators and suppliers of gas‑detection equipment working on oil/gas and petrochemical projects—particularly where legacy Soviet‑era technical rules remain in force or are used as reference.

Q: Is it current or superseded?

A: The original TU‑GAZ‑86 text dates from 30 April 1986 and came into force on 1 January 1987. It remains a widely cited technical document in commercial standards repositories, but its legal/mandatory status varies by country and it is not automatically part of contemporary mandatory national lists in many jurisdictions; users should verify current national regulations before applying it.

Q: Is it part of a series?

A: Yes—TU‑GAZ‑86 belongs to the TU‑GAZ family of technical requirements for gas instrumentation and replaced earlier TU‑GAZ‑75; related TU‑GAZ documents and later national rules should be consulted for a complete compliance picture.

Q: What are the key keywords?

A: Gas detectors, gas analyzers, signalizator, detector placement, explosion‑proof categories, alarm thresholds, oil & gas safety, TU‑GAZ‑86.
