device where the container is opened
4 Description
An oxygen escape device is designed and constructed so that exhaled breathing gas is ducted from the
facepiece into a circuit which contains a cartridge and a breathing bag where it is available for re-breathing.
device -
The cartridge contains chemicals which absorb exhaled carbon dioxide and - in case of a KO
2
humidity and generates also oxygen.
In case of a NaClO device, a chemical oxygen source (NaClO candle) generates the oxygen to be needed.
3 3
In case of a compressed oxygen device, oxygen is fed into the circuit at a suitable point by means of a
constant flow device or by a lung governed demand valve or by a suitable combination of both.
The breathing gas flow may be of the pendulum or loop type and excess gas is ejected via a relief valve.
5 Classification
5.1 General
Oxygen escape devices are classified according to their oxygen source and rated working duration in types
and classes.
5.2 Types of oxygen escape devices
Type C NaClO device;
3
Type D Compressed oxygen device;
Type K KO device.
2
5.3 Classes of oxygen escape devices
Oxygen escape devices are classified according to the rated working duration (see 6.19.1) which is defined by
performing a breathing machine test in accordance with 7.9.1 after the device is being exposed to shock in
accordance with 7.5.1 and vibration in accordance with 7.5.2.
Rated working duration will be defined in increments of 5 min up to and including duration of 30 min and
thereafter in steps of 10 min.
6 Requirements
6.1 General
All test specimens shall meet all requirements.
Where it is required in a specific clause the manufacturer shall declare that a failure modes and effect analysis
(FMEA) has been conducted.
The FMEA shall at least cover the following areas

prEN 13794:2014 (E)
The manufacturer shall maintain a copy of the FMEA in their records for a time period of at least 10 years or
for 5 years after the device ceases production whichever is the longest.
NOTE Further information is given in EN 60812 [1].
6.2 Design
The device shall be of reliable construction and as compact as possible.
The device shall be designed so as not to interfere with work activities when being carried. It shall be used in
accordance with the information supplied by the manufacturer.
The device shall be so designed that there are no protruding parts or sharp edges likely to be caught on
projections in narrow passages.
The surface of any part of the device likely to be in contact with the wearer shall be free from sharp edges and
burrs.
The device shall be so designed and constructed as to prevent ingress of external atmosphere within the
limits specified in this European Standard.
The device shall be so designed that the outside of the container can be easily cleaned.
The device shall be so designed as to prevent the chemical from entering the wearer's respiratory tract and
that saliva or condensate shall not interfere with the function of the device or cause any harmful effect to the
wearer.

It shall not be possible to initiate a quick start system inadvertently, if fitted.
It shall not be possible to don the device without initiating the quick start system, if fitted.
Devices for special use, i.e. in mining, shall meet the requirements specified in Annex A when tested in
accordance with Annex A.
Devices for training purposes only shall meet the requirements specified in Annex C when tested in
accordance with Annex C.
Training may also be carried out with the device specified in this standard.

corrosion. The materials used shall be able to withstand temperatures and mechanical stress to be expected
whilst being carried on the person as well as being stored on machines and vehicles.
Check in accordance with 7.3, test in accordance with 7.8.1 and 7.14.
Exposed parts, i.e. those which can be subjected to impact during use of the device, shall not be made of
aluminium, magnesium, titanium or alloys containing such proportions of these metals as will, on impact, give
rise to frictional sparks capable of igniting flammable gas mixtures.
Check in accordance with 7.3.
Any container or carrying container using such materials shall be adequately protected.

If national regulations allow the use of such containers or carrying containers then when tested for impact and
scraping no metal shall be exposed.
Non-metallic carrying containers shall be antistatic.
If the device is required to be antistatic during escape, materials used shall be antistatic.
11
Exposed parts shall have a surface resistance of lower than 10 Ω measured in accordance with
IEC 60079-32-2, 4.2. Exposed parts that do not meet this criterion may also be used if the maximum
transferred charge tested in accordance with IEC 60079-32-2, 4.10 does not exceed the maximum acceptable
values for the appropriate explosion group given in IEC 60079-32-1, Table 4 .
A general decision process for evaluating and testing plastic materials is given in Figure 1 (compare cited
documents).
Figure 1 — General decision process
Materials which come into direct contact with the wearer's skin shall not be known to be likely to cause
irritation or any other adverse effect to health.
Check in accordance with 7.3 and test in accordance with 7.14.
Care shall be taken in selecting materials that may come into contact with oxygen to ensure that no oxygen
ignition take place.
Devices using oxygen generating chemicals shall be known not to ignite or combust due to the elevated
temperatures of the device (caused by the exothermic chemical reaction) as a result of foreseeable use
addressed by a FMEA.
Check in accordance with 7.3.
6.4 Cleaning and disinfecting
All parts requiring cleaning and disinfecting shall be able to withstand cleaning and disinfecting agents and
procedures recommended by the manufacturer.
This shall be addressed in the FMEA.
