Full title and description

PB 09-170-97 — General rules on explosion safety for explosive- and fire-hazardous chemical, petrochemical plants and oil refineries. This regulatory document sets out principles and mandatory rules intended to prevent and mitigate explosion and fire risks at chemical, petrochemical and petroleum refining facilities.

Abstract

PB 09-170-97 (ПБ 09-170-97) provides general requirements for identifying explosion and fire hazards, classifying hazardous areas, and applying technical and organisational measures (design, equipment, ventilation, grounding, monitoring, and emergency response) to reduce the risk of vapour-, gas- and dust-air explosive mixtures in chemical, petrochemical and oil‑refining operations. The rule was approved in 1997 and later withdrawn from force when replaced by a newer code.

General information

• Status: Not effective; withdrawn by resolution of the Gosgortekhnadzor of the Russian Federation on 25 July 2003.
• Publication date: Approved 22 December 1997 (entered into force 22 Dec 1997).
• Publisher: Gosgortekhnadzor of the Russian Federation (Federal supervisory authority for industrial safety).
• ICS / categories: Environmental protection / fire protection and explosion protection — ISO classifier codes referenced (fire protection 13.220 and explosion protection 13.230).
• Edition / version: First edition, 1997 (original approval date 22 December 1997).
• Number of pages: 41 pages (PDF).

Scope

Applies to newly designed, under-construction, reconstructed and existing enterprises, organisations and facilities of the chemical, petrochemical, oil and gas processing industries, and other objects where substances that form vapour-, gas- and dust‑air explosive and fire‑hazardous mixtures are present. The document covers technical design, operational measures and supervisory requirements intended to control explosion/fire risk across the lifecycle of facilities.

Key topics and requirements

• Hazard identification and classification of premises and outdoor installations (zones for vapour/gas/dust atmospheres).
• Design and layout measures to separate, contain and ventilate hazardous processes and equipment.
• Requirements for electrical equipment, ignition-source control and explosion‑proof installations in classified areas.
• Grounding, bonding and protection against static electricity and electrostatic discharges.
• Safe selection, installation and operation of process equipment (pumps, compressors, storage vessels, piping).
• Monitoring, alarm, fire suppression and emergency shutdown systems.
• Organisational measures: operating procedures, maintenance, training, documentation and incident investigation.

Typical use and users

Used by process safety engineers, plant designers, safety and HSE managers, regulatory compliance teams, certifying bodies and technical auditors involved in chemical, petrochemical and refinery projects. It served as a regulatory reference for designers and operators to meet explosion‑safety obligations under Russian industrial‑safety supervision.
