FNiP No. 533 dated 15.12.2020 PDF

Full title and description

FNiP No. 533 dated 15.12.2020 — Order of the Federal Service for Environmental, Technological and Nuclear Supervision (Rostechnadzor) approving the Federal norms and rules in the field of industrial safety titled "General rules on explosion safety for explosion‑ and fire‑hazardous chemical, petrochemical and oil‑refining productions". The document establishes requirements for design, construction, operation, reconstruction, technical re‑equipment, maintenance and liquidation of hazardous production facilities in the chemical, petrochemical and oil‑refining sectors to prevent explosions and fires and to minimize their consequences.

Abstract

This Order (No. 533, 15 December 2020) codifies federal norms and rules for explosion protection applicable to chemical, petrochemical and oil‑refining facilities that handle flammable gases, vapours, liquids and combustible dusts. It defines hazard classification, mandatory safety measures across the lifecycle of facilities (projecting, construction, operation, reconstruction and decommissioning), requirements for protective systems and equipment, documentation and emergency planning, and the roles and responsibilities of operators and designers to ensure industrial explosion safety.

General information

• Status: Active / in force (approved by Order No. 533 of Rostechnadzor).
• Publication date: 15 December 2020 (Order No. 533).
• Publisher: Federal Service for Environmental, Technological and Nuclear Supervision (Rostechnadzor), Russian Federation.
• ICS / categories: Industrial/process safety; explosion and fire protection; chemical, petrochemical and petroleum refining industries; regulatory requirements for hazardous production facilities.
• Edition / version: Original issue approved by Rostechnadzor — Order No. 533 (15.12.2020).
• Number of pages: 128 (electronic/pdf format as published in the official text distribution copies).

Scope

The rules apply to design, engineering, construction, commissioning, operation, reconstruction, technical re‑equipment, repair, conservation and liquidation of hazardous production facilities (chemical, petrochemical and oil‑refining) where explosive or fire‑hazardous atmospheres may occur. They also cover manufacture, installation, adjustment, maintenance and repair of technical devices used at such facilities, and procedures for industrial safety expertise of documentation and safety justifications for technical changes or decommissioning.

Key topics and requirements

• Classification of explosion‑ and fire‑hazardous areas and assignment of hazard categories for process units and storage areas.
• Requirements for inherently safer design measures and process‑engineering safeguards to reduce explosion risks.
• Rules for selection, installation and maintenance of equipment, piping, ventilation and electrical installations in hazardous zones.
• Design and performance requirements for detection, alarm, control and automatic protection systems (including requirements that interface with functional safety standards and safety instrumented systems).
• Operational rules: process safety management, technological regulations, safe operating procedures, maintenance, testing and inspection regimes.
• Obligations for preparation and approval of safety documentation: project documentation, declarations and justifications of industrial safety, emergency response and mitigation plans (including plans for localization and elimination of accident consequences).
• Requirements for risk assessment, hazard analysis and demonstration of compliance when introducing technical re‑equipment or reconstruction.
• Training, qualifications and responsibilities of operating personnel, designers, contractors and supervisory bodies.
• Requirements for special facilities and activities (e.g., storage/transfer terminals, reservoir parks, pipeline transfer sites) and exceptions/limitations where some provisions do not apply.
• Provisions governing application of the rules to existing facilities and transitional arrangements for facilities commissioned before the rules entered into force.

Typical use and users

Primary users are regulatory compliance teams, HSE and process safety engineers, plant designers and project organizations, consulting firms performing industrial safety expertise, construction and maintenance contractors, emergency planners, auditors and legal departments of companies operating chemical, petrochemical and oil‑refining facilities. The document is used when preparing project documentation, safety justifications, performing risk assessments, specifying equipment for hazardous zones, and developing operational and emergency plans.

Related standards

Closely related regulatory and normative documents include other Rostechnadzor FNiP/FNIP orders addressing industrial safety and facility‑type rules; legacy national explosion‑safety rules (previous PБ documents replaced or supplemented by the Order); functional safety standards and guidance such as the national adoptions of IEC 61508 / IEC 61511 (for safety instrumented systems); relevant GOST standards for equipment and materials; and governmental acts and decrees governing industrial safety oversight and emergency preparedness. Users commonly apply these documents together when designing and certifying safety systems and preparing safety expertise.

FAQ

Q: What is this standard?

A: FNiP No. 533 (Order of Rostechnadzor dated 15 December 2020) is a set of federal norms and rules that establish mandatory explosion‑safety requirements for chemical, petrochemical and oil‑refining production facilities in the Russian Federation.

Q: What does it cover?

A: It covers classification of hazardous zones, design and engineering safeguards, equipment and installation requirements for hazardous areas, operational and maintenance rules, requirements for safety documentation and risk assessment, and emergency preparedness and mitigation measures for explosion and fire hazards across the facility lifecycle.

Q: Who typically uses it?

A: Regulators, plant owners and operators, process and safety engineers, designers, industrial safety experts, contractors, and auditors use it to ensure regulatory compliance and to design, operate and maintain facilities safely.

Q: Is it current or superseded?

A: The Order was approved on 15 December 2020 (Order No. 533) and is the controlling federal regulation for the subject matter from that date. Users should verify whether any later amendments, implementing orders or consolidated editions have been issued after 15 December 2020 when applying the rules.

Q: Is it part of a series?

A: Yes — it is one of a series of Federal norms and rules (FNiP / FNiP‑style orders) issued by Rostechnadzor that together form the regulatory framework for industrial safety in various sectors and for different facility types. It is used alongside other sector‑specific FNiP orders, national standards (GOSTs) and adopted international functional safety standards.
