Overview

EN 145:1997/A1:2000 is a European standard published by CEN addressing the requirements for respiratory protective devices, specifically self-contained closed-circuit breathing apparatus. This amendment to the original EN 145:1997 standard provides updated specifications related to devices using compressed oxygen or compressed oxygen-nitrogen mixtures. The document outlines essential criteria for design, testing, and marking of these respiratory devices to ensure safety and reliability in various working environments.

The standard is crucial for manufacturers, testing laboratories, and end-users involved in respiratory protection, particularly for applications requiring autonomous breathing support with closed-circuit systems.

Key Topics

• Scope and Application
  Targets self-contained closed-circuit breathing apparatus that utilize compressed oxygen or oxygen-nitrogen gas mixtures. It defines the technical and safety requirements needed for effective respiratory protection.

• Device Requirements
  Specifies construction features, performance criteria, and safety features that the breathing apparatus must fulfill to comply with European safety regulations.

• Testing Procedures
  Describes mandatory testing protocols to verify the functionality, durability, and reliability of the breathing apparatus under operational and stress conditions.

• Marking and Identification
  Outlines clear marking guidelines to ensure traceability and compliance information is visible on the equipment, facilitating easy identification and certification validation.

• Amendment Details
  This document serves as an amendment to the original EN 145:1997, updating and refining requirements based on technological advancements and feedback from practical usage.

Applications

• Industrial Safety
  Vital for workers operating in hazardous environments where toxic gases or oxygen-deficient atmospheres are present, such as chemical plants, mining, or confined spaces.

• Firefighting and Emergency Response
  Used by firefighters and rescue teams requiring reliable closed-circuit breathing apparatus that provide extended autonomy without external air supply dependency.

• Military and Defense
  Applicable in defense scenarios requiring sophisticated respiratory protection against chemical or biological threats with enhanced mobility and endurance.

• Diving and Underwater Operations
  Enables safe underwater breathing through closed-circuit systems that recycle exhaled gases with oxygen replenishment, extending dive duration and minimizing bubbles.

Related Standards

• EN 137 - Respiratory Protective Devices - Self-Contained Open-Circuit Breathing Apparatus
  For devices relying on compressed air rather than oxygen-based mixtures.

• EN 136 - Respiratory Protective Devices - Full Face Masks
  Covers masks compatible with closed-circuit and other breathing apparatus.

• ISO 23269 - Respiratory Protective Devices
  International guidelines complementing European standards on testing and performance.

• EN 143 - Particle Filters for Respiratory Protective Devices
  Details filtration requirements when used alongside breathing apparatus.
