Overview
EN 145:1997 (CEN) - Respiratory protective devices - Self-contained closed-circuit breathing apparatus compressed oxygen or compressed oxygen‑nitrogen type - Requirements, testing, marking - specifies minimum requirements for self-contained closed‑circuit breathing apparatus (closed‑circuit SCBA) of the compressed oxygen (O2) and compressed oxygen‑nitrogen (O2–N2) types. The standard applies to respiratory protective devices used for work and rescue operations, excluding escape apparatus and diving apparatus. EN 145:1997 includes provisions for design, performance and laboratory and practical performance tests to verify compliance, and sets requirements for marking and documentation.
Key Topics
- Scope and definitions relevant to closed‑circuit self‑contained breathing apparatus (SCBA closed‑circuit).
- Minimum performance requirements for devices using compressed oxygen or oxygen‑nitrogen mixtures.
- Compliance testing: the standard requires laboratory and practical performance tests to assess conformity with requirements.
- Marking and documentation obligations to ensure traceability, user safety information and conformity evidence.
- Design and safety considerations covering functional reliability, user interface and maintenance aspects (as required for respiratory protective devices).
Applications and Users
EN 145:1997 is primarily used by organizations involved in the specification, manufacture, testing and procurement of closed‑circuit breathing apparatus:
- Manufacturers and designers of closed‑circuit SCBA who need to demonstrate compliance with European minimum requirements.
- Testing and certification bodies that perform laboratory and practical assessments against standard criteria.
- Procurement officers and safety managers in emergency services, industrial plants, rescue teams and hazardous materials operations selecting respiratory protective devices.
- Regulatory and compliance teams ensuring that supplied equipment meets European standardization requirements.
This standard helps ensure that self‑contained closed‑circuit breathing apparatus perform reliably, are properly marked, and can be assessed through standardized testing - supporting safer use in professional respiratory protection applications.
