Full title and description

GOST R 53255-2019 — Firefighting equipment. Self-contained open-circuit compressed-air breathing apparatus. General technical requirements. Test methods. (Russian: ГОСТ Р 53255-2019 «Техника пожарная. Аппараты дыхательные со сжатым воздухом с открытым циклом дыхания. Общие технические требования. Методы испытаний»).

Abstract

This national standard establishes classification, general technical requirements and standardized test methods for self-contained open-circuit compressed-air breathing apparatus used by firefighters and related emergency responders to protect respiratory organs and vision in toxic, smoke-filled and otherwise non-breathable atmospheres. It covers performance, climatic and mechanical durability tests, breathing-resistance limits, rescue-device requirements and marking/identification.

• Publisher: Federal Agency on Technical Regulation and Metrology (Rosstandart) / national standard of the Russian Federation.
• ICS / categories: Protective devices — respiratory protective devices; national classification often shown as 13.340.30 (devices for respiratory protection).
• Edition / version: Edition 2019 (GOST R 53255-2019).
• Number of pages: Approx. 44 pages (published commercial/registry copies list 44 pages).

Scope

The standard applies to self-contained open-circuit compressed-air breathing apparatus intended for use in firefighting and related rescue operations. It specifies classification by intended use (general-purpose and special-purpose/climate versions), required operational performance across specified breathing regimes (examples: lung ventilation test regimes at about 30, 60 and 100 dm3/min), pressure and filling limits for supply cylinders, environmental/climatic endurance (including low- and high-temperature and high-humidity tests), mechanical resistance tests, and methods to assess protective time (duration of protective action) and breathing resistance. Optional features such as telemetry/communication modules and refill system interfaces are addressed where relevant.

Key topics and requirements

• Classification of apparatus (general-purpose and special-purpose/climatic versions) and corresponding operational temperature/humidity ranges.
• Performance test regimes including lung ventilation rates (30, 60 and 100 dm3/min) used to verify functional performance and rescue-device operation.
• Limits on breathing resistance and CO2 build-up, measured by specified test methods and acceptance criteria.
• Cylinder pressure and refilling system requirements (examples include design/operational pressures referenced in test procedures).
• Climatic and mechanical durability tests (cold, heat, humidity, vibration, shock) and sequence-of-tests protocols.
• Requirements and test methods for associated facepieces and sealing assemblies (often covered in companion standards).
• Marking, documentation, identification of protective time, maintenance and inspection requirements necessary for safe use and certification.

Typical use and users

Primary users include municipal and industrial fire brigades, emergency and rescue services, manufacturers and designers of breathing apparatus, testing and certification laboratories, conformity-assessment bodies and procurement authorities responsible for specifying and accepting firefighting respiratory protective equipment. The standard is used to design, test, certify and procure SCBA units for firefighting applications.
