This European Standard specifies minimum requirements for fresh air hose breathing apparatus for use with a full face mask, a half mask or mouthpiece assembly as a respiratory protective device. Two classes of apparatus are covered; the differentiation resulting from mechanical performance and not respiratory protection. Escape and diving apparatus and that used in abrasive blasting operations are not covered by this standard. Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
Atemschutzgeräte - Frischluft-Schlauchgeräte in Verbindung mit Vollmaske, Halbmaske oder Mundstückgarnitur - Anforderungen, Prüfung, Kennzeichnung
Diese Europäische Norm enthält Mindestanforderungen für Frischluft-Schlauch- geräte als Atemschutzgerät, die in Verbindung mit einer Vollmaske, Halbmaske oder Mundstückgarnitur verwendet werden. Zwei Geräteklassen sind vorgesehen, wobei der Unterschied in der mechanischen Ausführung und nicht im Atemschutz liegt. Flucht- und Tauchgeräte sowie Geräte, die bei Strahlarbeiten eingesetzt werden, sind nicht Gegenstand dieser Norm. Die Norm enthält Laborprüfungen und praktische Leistungsprüfungen, um die Übereinstimmug mit den Anforderungen feststellen zu können.
Appareils de protection respiratoire - Appareils de protection respiratoire à air libre avec masque complet, demi-masque ou ensemble embout buccal - Exigences, essais, marquage
La présente norme européenne fixe les exigences minimales des appareils de protection respiratoire à air libre utilisés avec masques complets, demi-masques ou ensembles embouts buccaux en tant qu'appareils de protection respiratoire. Deux classes d'appareils sont couvertes, la différenciation étant fonction des performances mécaniques et non pas de la protection respiratoire offerte. Les appareils destinés à l'évacuation, à la plongée et ceux utilisés dans les opérations de projection d'abrasifs ne sont pas couverts par cette norme.

Overview
EN 138:1994 (CEN) is a European standard that specifies minimum requirements for fresh air hose breathing apparatus intended for use with a full face mask, half mask, or mouthpiece assembly. The standard defines two classes of apparatus distinguished by mechanical performance (not by level of respiratory protection), and sets out requirements for testing, marking, and conformity assessment. Not covered are escape and diving apparatus or equipment used in abrasive blasting operations. The standard includes both laboratory and practical performance tests to assess compliance.
Key topics and requirements
- Scope and application
- Devices covered: fresh air hose breathing apparatus used with full face masks, half masks, or mouthpiece assemblies.
- Exclusions: escape apparatus, diving apparatus, and abrasive blasting equipment.
- Classification
- Two classes based on mechanical performance characteristics; classification does not imply different respiratory protection levels.
- Performance requirements
- Minimum mechanical and functional requirements to ensure safe operation of hose-fed breathing systems.
- Testing
- Laboratory tests and practical performance tests are specified to verify compliance with performance requirements.
- Marking
- Requirements for durable and legible marking so users and inspectors can identify compliant equipment, class designation, and relevant information.
- Conformity assessment
- Procedures for assessing whether an apparatus meets the standard through the prescribed tests.
Applications
EN 138:1994 is intended to guide the design, manufacture, testing, and selection of fresh air hose breathing apparatus in workplaces and operational settings where a continuous supply of breathing air via hose is used. Typical practical uses include:
- Industrial environments where hose-fed systems supply clean air for maintenance or inspection tasks
- Confined-space entry where supplied-air systems (with full face or half masks) are used to protect workers
- Maintenance and safety programs in chemical plants, manufacturing, and similar facilities that use supplied-air respirators
Who uses this standard:
- Manufacturers designing hose-fed breathing apparatus
- Testing laboratories conducting laboratory and practical performance evaluations
- Health & safety professionals and procurement officers specifying compliant respiratory protective equipment
- Regulatory and certification bodies assessing conformity with European requirements
Related standards
- Other EN/CEN standards address different types of respiratory protective devices (for example, escape apparatus, diving equipment, and abrasive blasting respirators) - these are outside EN 138’s scope and should be consulted where applicable.
