Personal safety — Personal protective equipment — Guidelines on compatibility testing of PPE
This document describes compatibility for ensembles of personal protective equipment (PPE) to be used by personnel where operating situations and processes require more than one piece of PPE. Where there is more than one risk to health and safety, it is necessary to wear or use more than one item of PPE at the same time. Such equipment should be compatible and continue to be effective to minimise the risks. This document includes examples of interactions between items of PPE, between PPE and the operating environment and the effects of PPE on the correct functioning of integrated sensors and electronic devices. This document provides suggestions of test procedures to assess the effects of any interactions and identify unacceptable restrictions to safe operations. NOTE The principles of this document are also applicable to assessment of interactions with other items in an ensemble that are necessary to the work and that are not PPE, for example cap lamps, instruments, tools. This document is also intended to be a general guideline for writers of performance requirements standards and test methods for PPE. This document can also be used by PPE manufacturers, distributors, solutions providers, purchasers, wearers and employers as guidance in PPE design and selection.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction
When, following a risk assessment, users are required to wear more than one type of personal protective
equipment (PPE) to minimise the risk to their safety, health and well-being, it is important that there
are no negative interactions between wearers and the PPE, between the items of PPE and between the
PPE and other necessary items to the operations and processes.
Any item of PPE introduces some barrier between part(s) of the body and the environment. This barrier
is essential for protection, but it is recognized that this can have unwanted side-effects on the wearer
in terms of imposing additional physical effort, hindering movement, impairing sensory perception or
causing discomfort. Such side-effects can reduce the efficiency and accuracy of task performance and/
or discourage the user from wearing the PPE and, consequently compromising the level of protection
afforded.
This document deals with the identification of issues and provides guidance for test procedures to
assess the compatibility of items of PPE worn together in an ensemble and between the PPE and the
operating environment and processes.
International standards for PPE and requirements and test methods are generally related to individual
items of PPE and only a few, for instance ISO 10333-1, ISO 16073-2 and ISO/TS 11999-2, include the
assessment of interactions with other items of PPE. For instance, the interface between PPE items at
the neck, wrist and ankle needs to provide the appropriate coverage and functionality to protect the
wearer from hazards.
The ultimate responsibility for protective equipment is with the wearers’ employer, however there
may be different levels of shared responsibility with manufacturers and/or wearers themselves. The
employer is also the authority on their individual operating environment and processes
Since it is expected that a wide range of equipment may be used by personnel, it is important to note
that most PPE are not approved as an ensemble. It is the responsibility of those selecting the equipment
to determine if the selected PPE items are compatible and do not impair the performance of other
PPE nor impede the ability of the wearer to conduct their activities safely. Given the importance of
compatibility, those selecting the PPE ensemble should also be responsible for, or in close coordination
with those responsible for the respiratory protection program. Suitability factors should include, but
not be limited to issues such as correct use of each item of PPE, mobility, dexterity, field of view and
clarity of vision. Heat stress is an issue too but it is not addressed in this document.

4 Compatibility
4.1 General
Compatibility is an issue when different types or combinations of PPE in an ensemble are worn together.
This may mean that each item of PPE will not be compatible with each other or may interfere with each
other. This may lead to protection being compromised and/or restrictions caused by the PPE that may
impede the ability to carry out the tasks. When considering compatibility of items of PPE, there are
three main criteria that need to be evaluated in the interest of safety:
— Interfaces – interface between PPE need to ensure that whatever the movement of the person (see
Clause 6) does not cause a movement restriction or a lack of protection.
— Performance – the PPE that is used needs to provide the same minimum protection and it is necessary
to identify the weakest item of PPE in the ensemble and how this may affect the user (can he/she
realise when an item of PPE is about to fail). There are different tests that exist to permit testing of
a full ensemble to understand the weakest link (for example chemical, heat and flame). (See 4.4 and
4.5).
— Use condition are related not just to the expected movements of the user but also related to the
length of time the PPE is intended to be worn, the spatial conditions the wearer is in, but also the
climatic conditions (humidity, temperature, rain, etc.) of the use environment.
Compatibility is also an issue when PPE forms an interface with the user, the environment in which it is
used and any integrated and external devices used including electronic.
While product standards can address the first two, the third remains an important consideration in the
application of a dynamic risk assessment process and the safe use of PPE. These considerations need to
cover the PPE and any ancillary or associated equipment, which is used in conjunction with each other
for the holistic and overall protection of the user.
This document and other documents that cover at least partially compatibility, like ISO 16073-2,
ISO 17723-1, ISO 18639-1, ISO/TS 11999-2, can only address the issue in general terms as guidance. The
compatibility of a particular PPE ensemble can only be assessed by personnel familiar with the needs,
processes and use conditions at which the tasks are carried out and set of activities. This will require
an assessment of the required components of an ensemble and the potential compatibility issues, based
on a risk assessment of the tasks and processes involved.
Any user, manufacturer or any test laboratory, that wishes to assess compatibility of a particular
ensemble in a specific application under specific use conditions or compare the functioning of different
ensembles, will need to be guided on the selection and design of appropriate test protocol(s) that ensure
reproducibility of the results, but also includes hazards and risks to which the user is exposed including
the use conditions in which the tasks and activities are carried out.
4.2 Combination of items of PPE known to create problems
The compatibility of the combination of PPE items should be tested. The easiest way to assess
compatibility of your PPE items is to undertake an audit. The compatibility test should cover the items
of PPE required and be cross-referenced against users’ needs, use conditions at which the tasks are
carried out, and the set of activities. A comprehensive audit will optimise user acceptance and wearing
time. Table 1 identifies the interfaces known to create potential problems (identified as “x”).

4.3 Multiple hazard compatibility
Establish whether a combination of PPE (for example, harness, RPD) has the potential for a negative
effect on other items of PPE (for example, garment) and the protection that the other PPE needs to
provide (for example, chemical, heat and flame) or presents other risks due to compression, creation of
folds, etc.
4.4 Consideration of environmental compatibility
— Establish appropriate PPE compatibility in the use environment based on an environmental risk
assessment to achieve a sufficient level of protection.
— In the case of using a combination of PPE in a certain use environment, establish that each item
of PPE and/or combination of PPE meets the appropriate level of protection to avoid interference
between items of PPE and with the use environment.
— Combinations of items of PPE should be ergonomically appropriate (not too hot, not too humid, not
too heavy, etc.) for the wearer to complete the mission objective or practical performance test
4.5 Thermal protection compatibility
The thermal protective properties of a different PPE should be reviewed so that the overall protection is
not disproportional for one part of the body or cause a risk of failure of critical equipment. In addition,
overprotection of certain body parts would increase the thermal physiological impact of the PPE on
the wearer. Wearers should also be aware of the materials of the underclothing when using protective
clothing against heat and flame to consider the probable melting properties of underwear.
ISO 13506-1 and ISO 13506-2 can be used to assess heat and flame ensembles to identify any weaknesses
to the full system.
4.6 Chemical protection compatibility
The chemical protective properties of the outer layer are critical in providing chemical protection for
the user whether this is purely chemical or dual protection (for example, chemical in combination with
heat and flame).
Repellency of chemicals, in garment such as for structural firefighting, station wear, rescue clothing,
needs to be ensured after cleaning through re-impregnation. If not, the garment could absorb or let
through chemicals during an incident or cleaning operations. Some chemicals (for example, solvent, oil)
may have a negative impact the heat and flame protection of the garment, glove, boot, etc.
Wear and tear, and specifically abrasion, can negatively impact the chemical protection of boots, gloves
and garments. Helmets may lose their robustness if exposed to chemicals (for example, solvents, acids).
Chemical protection of the ensemble needs to ensure that, if one part for example, gloves, protect
against a specific chemical, set of chemicals or mixtures, then the other parts (for example, boots,
garments, RPD, visor) provide smaller protection.
— ISO 17491 series can be used to assess chemical protection of ensembles against liquids, gases and
particulates to identify weaknesses in the full system.
— ISO 17491-1 for gas ingress.
— ISO 17491-2 for particulates testing.
— ISO 17491-3 Liquid jet resistance.
— ISO 17491-4 (Method B) Liquid spray (high level spray) resistance.
— ISO 17491-4 (Method A) Liquid mist (low level spray) resistance.
— ISO 17491-5 Manikin liquid spray resistance.
These tests should not be seen as being hierarchical. Tests from ISO 17491-3 through ISO 17491-5 are
water-based tests at various pressures, liquid volumes, angles and surface tensions.
4.7 Mechanical protection compatibility
The mechanical protective properties of the outer layer are critical to providing protection of user. The
mechanical properties can have different functions:
— Mechanical protection;
— Longevity of the PPE (maintaining the integrity of the PPE);
— Avoidance of snagging.
Therefore, the specific function of the mechanical properties is critical when assessing them as a user.
4.8 Examples of issues
4.8.1 General
It is important that each item of PPE complies with the relevant requirements in the specific product
standard(s) and is selected and used in accordance with the relevant document(s) (if published).
ISO 11999-1, ISO 16073-1, ISO/TR 21808 refer to PPE in general and Table 2 contains examples of
standards and documents published by ISO and IEC applicable to components of an ensemble. This list
is not guaranteed to be exhaustive nor current.

NOTE Users of this document should check that these documents are current or if further relevant standards
have been created since publication.
For some applications, there are other guidance documents related to compatibility that should be read
in conjunction with this document. These include ISO 16703-2, ISO 17723-1, and ISO/TS 11999-2.
If there is an issue that donning and doffing the PPE with appropriate convenience and speed, it may
require the creation of instructions on the method and, in particular, the orders of donning or doffing
the PPE.

4.8.2.1 Electronic safety equipment
Item of PPE with electronic safety equipment, sensors and/or actuators should be reliable and not
hinder the wearer. The PPE worn should not hinder the transmission of signals of the sensors. Any
power supply (for example batteries) for the sensors and actuators should not hinder or harm the
wearer.
EXAMPLE If location information is sent to the wearer by tactile signals, it is necessary that the sense of the
skin will detect the tactile signals:
— Electronic devices and resistance to heat, or chemical
— Effect of fast temperatures change
— Thermal safety of electronics (temperature during operation against skin)
— Electrical safety (for example, electric shock IEC 60598-2-4)
— Resistance to water/humidity – IEC 60529 IP rating 44 to 47 is recommended (see classification
based on the second digit). Possible, there are more areas of application in which a requirement, for
example, to a higher IP protection class, an explosion-proof design or resistance to salty moisture is
required.
— Batteries, in particular Lithium ion, secondary batteries placed on the market should comply with
IEC 62133-2. Battery housings should meet IP protection class 44
— Sinusoidal vibrations
— Safety towards electromagnetic fields (for example, EN 50527 series)
— Explosive zones – A risk assessment is to be carried out according to CEN/TR 16832 to determine
the level of protection needed due to the type of atmosphere (particulate or gas). IEC 60079 series
for intrinsic safety
— Fail safe attributes of electronics
— Other considerations
In addition, for integrated smart textiles and non-textile devices which do not or do not solely
interact with the user but with an external monitoring system (for example, a command centre),
there are, among others, several ethical questions that might need to be assessed by the end user or
the employer, which are outside the scope of this document, including but not limited to:
— any communication to stop worker from acting,
— any disobedience to such orders, any psychological effects of these,
— the effect if worker goes too far and is injured (who has the responsibility for the injury)
— how the insurance companies or the law will view any of this information in the event of any
injury.
4.9 Applicability of test methods to ensembles
4.9.1 General
The applicability of guidelines for PPE test methods should be assessed with any ensemble to ensure
compatibility so that the wearers can don and doff within an appropriate time, perform their donning
to doffing movements, maintain health and safety and/or use the PPE as intended. The list of applicable
test method guidelines is given in Table 3 and Table 4.
