Rostechnadzor Order No. 217 dated 03.06.2016 PDF

Full title and description

Order of the Federal Service for Environmental, Technological and Atomic Supervision (Rostechnadzor) No. 217 dated 3 June 2016: "On approval of the Safety Guidance 'Methods for justifying blast resistance of buildings and structures in explosions of fuel–air mixtures at hazardous production facilities'". The document approves a guidance that provides recommendations and calculation procedures for assessing blast loads and justifying the blast resistance of buildings and structures affected by fuel–air mixture (FAM) explosions arising from industrial accidents at hazardous production facilities.

Abstract

This Rostechnadzor guidance gives methodological recommendations for identifying explosion scenarios, calculating zones of overpressure and shock-wave impact from fuel–air mixture clouds, performing quantitative risk assessment for building damage, and establishing criteria for blast resistance of structures at hazardous production sites. It includes definitions, indicators of explosivity, a method for quantitative risk estimation, worked calculation examples and appendices with tables and terms. The guidance is intended to support compliance with related federal industrial safety rules and declarations of industrial safety.

General information

• Status: Approved by Rostechnadzor (Order No. 217 of 03.06.2016). Public databases list the guidance as adopted; some catalogues indicate later cataloguing metadata that the entry was "replaced" in their systems — users should verify current legal status in official registers before use.
• Publication date: Approved 3 June 2016 (entered into force with the approving order).
• Publisher: Approved by the Federal Service for Environmental, Technological and Atomic Supervision (Rostechnadzor); published in print by specialized technical publisher (editions in bibliographic databases show ZAO NTC PB as the print publisher for 2016).
• ICS / categories: Regulatory / industrial safety guidance for explosion protection and risk assessment at hazardous industrial facilities (no single ICS code explicitly listed in primary sources).
• Edition / version: Version approved by Rostechnadzor Order No. 217 (03.06.2016). Subsequent cataloguing entries may record later editorial metadata — check the authoritative register for updates.
• Number of pages: Bibliographic records list approximately 28–30 pages depending on the edition/printing (catalogue entries vary).

Scope

The guidance is intended for use when substantiating the blast resistance of buildings and structures exposed to explosions of fuel–air mixtures formed in the atmosphere during industrial accidents at hazardous production objects. It provides procedures for determining shock‑wave zones, computing the risk indicator of structural failure, and applying the method of quantitative risk assessment for explosion scenarios. It is recommended for use during design, construction, reconstruction, major repair, technical re‑equipment and operation (including decommissioning) of hazardous production facilities. The guidance explicitly does not cover assessment of internal explosions inside vessels or apparatus.

Key topics and requirements

• Definitions, abbreviations and terms relevant to explosion risk and blast resistance (appendices with terms and notation).
• Identification and classification of accident scenarios that produce fuel–air clouds, including probabilities of ignition and delayed ignition scenarios.
• Methods for calculating blast parameters (overpressure on shock‑wave front), maximum range of shock effects and zones of destruction for given scenarios.
• Procedure for quantitative evaluation of explosion risk and computing a risk indicator for structural damage; comparison with admissible risk criteria to justify blast resistance measures.
• Recommendations for selecting calculation scenarios, meteorological and release parameters, and for accounting for cascade accidents and different physical manifestations (BLEVE, jet fires, pool fires where relevant).
• Worked examples and tables for main explosivity indicators, plus sample calculations for zones of destruction and risk estimates (appendices).

Typical use and users

Primary users are industrial safety engineers, structural engineers, risk analysts, designers of hazardous facilities, independent safety consultants and regulatory inspectors. Typical uses include substantiating structural resistance in safety documentation (declarations of industrial safety), supporting design and retrofit decisions, developing special technical conditions for construction, and performing quantitative risk assessments for accident scenarios involving fuel–air mixtures.

Related standards

The guidance is intended to be used together with federal norms and rules cited in the order, notably the Federal rules "General explosion‑safety rules for explosion‑fire‑hazardous chemical, petrochemical and oil‑refining productions" (Rostechnadzor order No. 96 of 11.03.2013) and "General requirements for justification of safety of a hazardous production facility" (Rostechnadzor order No. 306 of 15.07.2013), as well as other Rostechnadzor methodological guides on modelling releases and consequences of accidental explosions and fires. Users should cross‑reference those documents when preparing calculations and safety substantiation.

FAQ

Q: What is this standard?

A: It is a Rostechnadzor safety guidance (approved by Order No. 217 of 3 June 2016) titled "Methods for justifying blast resistance of buildings and structures in explosions of fuel–air mixtures at hazardous production facilities" that provides methodological recommendations and calculation procedures for assessing blast effects and justifying structural resistance.

Q: What does it cover?

A: It covers identification of explosion scenarios involving fuel–air mixtures, calculation of shock‑wave parameters and zones of impact, a quantitative method to estimate the risk of structural damage, criteria for allowable risk, and example calculations and tables. It does not cover internal explosions inside equipment or vessels.

Q: Who typically uses it?

A: Industrial safety specialists, structural and design engineers, risk assessment consultants, and regulatory inspectors working with hazardous production facilities use the guidance to substantiate structural safety measures and to prepare or review industrial safety documentation.

Q: Is it current or superseded?

A: The document was approved on 3 June 2016 by Rostechnadzor (Order No. 217). Public catalogues and legal databases show the approved guidance in their records; some library/cataloguing entries mark the item as "replaced" in their own systems. Because status entries vary between databases, users who require authoritative legal certainty should check the current register or the official Rostechnadzor statements for any later amendments or superseding orders before relying on the guidance for compliance decisions.

Q: Is it part of a series?

A: Yes — it is one of several Rostechnadzor methodological/safety guides dealing with assessment of consequences and risks at hazardous production facilities (for example, related guides on modelling releases and consequence assessment are referenced in the text). The guidance is intended to be used alongside other Rostechnadzor federal rules and methodological guides cited in the order.

Q: What are the key keywords?

A: Blast resistance; fuel–air mixture (FAM); explosion scenarios; overpressure; shock‑wave; quantitative risk assessment; hazardous production object; Rostechnadzor Order No. 217; industrial safety guidance.
