Full title and description

FNiP No. 420 dated 20.10.2020 — Federal norms and rules in the field of industrial safety: "Rules for conducting industrial safety expertise" (Russian: Федеральные нормы и правила в области промышленной безопасности «Правила проведения экспертизы промышленной безопасности»). This federal regulation establishes requirements and procedures for conducting expert examinations (expertise) of industrial safety for hazardous production facilities and their technical devices, buildings and structures.

Abstract

This document prescribes the scope, procedure, and formal requirements for organizing and performing industrial-safety expertise (экспертиза промышленной безопасности) of objects and technical devices subject to the Federal Law on industrial safety of hazardous production facilities. It defines obligations for expert organisations and experts, the contents and form of expert conclusions, requirements for inspections, documentation and registry entries, and provisions for post-expertise measures. The rule entered into force at the start of 2021 and has since been amended.

Scope

The Rules apply to the conduct of industrial‑safety expertise for objects listed in article 13 of Federal Law No. 116‑FZ (hazardous production facilities) and to technical devices, buildings and structures on such facilities where an expertise is required by law, by project documentation or when safety documentation lacks reliable data (for example, missing service-life data). The document sets boundaries for when and how expertise must be performed and specifies cases that are excluded (e.g., certain insurer reviews).

Key topics and requirements

• Definitions and types of industrial‑safety expertise and the objects subject to examination (technical devices, buildings, structures, systems).
• Qualification, composition and responsibilities of expert organisations and individual experts; rules for appointment and conflict-of-interest controls.
• Procedures for on-site inspection, non‑destructive testing, technical diagnostics and required investigative actions during expertise.
• Required content, structure and formal requisites of the expert conclusion; conditions for issuing positive, conditional or negative conclusions and mandatory corrective measures.
• Obligations to enter expert conclusions into the official registry (timelines and recordkeeping requirements are specified in amended editions).
• Rules for repeat expertise, circumstances triggering re‑examination (after accidents, expiry of safe‑operation periods, major repairs or design changes).

Typical use and users

Used by: expert organisations and individual experts performing industrial-safety expertise; operating organisations of hazardous production facilities (owners/users) that must commission expertise; state supervisory authorities and auditors; designers and constructors preparing documentation; insurance and legal professionals involved in compliance and incident investigations. Typical use cases include initial and periodic expertise, post-incident re‑examination, assessment of equipment with unknown service life, and verification of corrective actions following an expert conclusion.

Related standards

Key related normative acts and standards include Federal Law No. 116‑FZ "On industrial safety of hazardous production facilities" (1997), other Rostechnadzor federal norms and rules (e.g., regulations on explosion safety and pipeline safety), and applicable construction and technical standards (SNiP/GOST/technical regulations) referenced in the Rules. The Rule itself has been amended by subsequent Rostechnadzor orders (see Edition / version).
