5 Situations for using RPD

RPD is considered to be at the bottom of the hierarchy of control measures and should only be used

after an acceptable case for its use has been established by way of an appropriate risk assessment. RPDs

are used to further reduce inhalation exposures to hazardous atmospheres:
— when sufficient engineering and administrative controls are lacking;

— when these controls are not reasonably practical (maintenance, escape or rescue work);

— prior to implementing or improving a control measure.
6 RPD programme
6.1 General

The RPD programme includes processes for selecting, using and maintaining RPD to ensure adequate

protection to the wearer.

Prior to using RPD, it is essential to establish a written RPD programme. The RPD programme needs to

be understood by all persons within the organization, as appropriate.
6.2 RPD programme elements
The RPD programme consists of the following elements:
a) roles and responsibilities (see 6.3);
b) RPD programme implementation (see 6.4);
c) risk assessment (see Clause 7);
d) selection procedures (see Clause 7);
e) medical assessment (see 7.3.3.2);
f) fit testing (see 7.4);
g) training (see 7.5);
h) use (see 7.6);
i) maintenance procedures (see 7.7);
j) storage (see 7.8);
k) programme review (see 7.9);
l) records and record keeping (see 7.10).

---------------------- Page: 10 ----------------------
ISO/TS 16975-1:2016(E)
6.3 Roles and responsibilities
6.3.1 General

All persons involved in the respiratory protection programme shall be competent in their area of

responsibility within the RPD programme and maintain the appropriate knowledge, experience and

training to effectively carry out their duties.
6.3.2 Employer
The employer shall
— be responsible for the entire RPD programme,
— define, implement and document the RPD programme,

— provide adequate resources and organization to ensure the programme’s continued effectiveness, and

— assign an RPD programme administrator.
The employer and the programme administrator may be the same person.
6.3.3 RPD Programme administrator

The programme administrator shall be responsible for effective management of the entire RPD

programme.
6.3.4 Wearer
The wearer shall be responsible for
— using the RPD in accordance with the instructions and training received,
— reporting of any damage, defects or non-function of the RPD provided, and

— reporting any physical or medical limitations or changes that can impact their ability to wear and

use the RPD correctly.
6.4 RPD programme implementation

The RPD programme shall be implemented, evaluated and updated as necessary to reflect those

changes in workplace conditions that affect RPD use.
7 Risk assessment and RPD selection
7.1 General

A risk assessment is essential for the correct selection and use of RPD. It shall be conducted by a

competent person before RPD is used for routine work, emergency work, rescue (including response to

catastrophic incidents) or escape.
The risk assessment shall be conducted
— prior to the start of all new work processes,
— if the work conditions change,
— for new wearers, not covered by the existing suitability assessments, and

— periodically thereafter, at least annually or in accordance with national or local regulations.

---------------------- Page: 11 ----------------------
ISO/TS 16975-1:2016(E)

The RPD selection procedure, shown in the following flow charts in 7.2 and described in 7.3, uses the

information gathered from the risk assessment which shall include the following.

a) The Hazard Assessment flow charts identify the nature of the hazard, e.g. oxygen deficiency,

contaminant level, Immediately Dangerous to Life or Health (IDLH).

b) The Adequacy Assessment flow chart determines the protection level required for the hazard.

c) The Suitability Assessment flow charts identify the factors to consider when selecting the RPD that

meets the needs of the wearer and is appropriate for the task and the environment.

d) The special application flow chart identifies the minimum work rates and the minimum protection

classes of the various classes within the special applications.

This is an example of a navigation marker. These navigation markers precede text and are cross

referenced in the flow charts. All markers are listed sequentially in 7.3. In addition, a flow chart may

contain markers out of sequence. Follow the flow charts in the order given above and always begin at

the top block. Read the contents of each block in sequence and follow the decision logic.

The diamond shape indicates that a decision shall be made in order to proceed. Answer each with

a “Yes” or “No” response and follow the arrow to the next block.

The rhomboid shape provides data that leads to the final specification and class of suitable RPD.

The “wave shape” is an instruction to document the output of the suitability assessment.

The irregular pentagon is an instruction to go to the next flow chart.
The cylinder is an indication of the mode of operation.

Record the outcome of the selection procedure in accordance with ISO/TS 16975-2. The example of

the selection record sheet can be used (see Annex J). Where the table in Annex J recommends seeking

professional advice RPD manufacturers/suppliers and safety consultants are a good source of

information.

7.3 Selection procedure
7.3.1 Hazard assessment
7.3.1.1 General

The hazard assessment shall identify the nature of the hazard(s) present for which respiratory

protection may be required.
7.3.1.1.1 Oxygen deficiency

The potential for oxygen deficiencies shall be considered. When national or local regulations that

relate to oxygen deficiency levels exist, these should be followed.
7.3.1.1.2 Identification of contaminants

The contaminant(s) likely to be present as gas, vapour or particle shall be identified.

All materials used, produced or stored, including raw materials, end products, by-products and wastes,

should be reviewed by assessing the work process and by referring to the safety data sheets (SDS).

From this review, the contaminant(s) that may be present in the workplace shall be identified.

National or local regulations that relate to specific contaminants (e.g. asbestos, lead, benzene) shall be

followed. If the contaminant is unknown and if there is a national or industry guidance document that

is specific to the task, then the assigned protection factors (APF) or the recommended Protection Level

shall be chosen.

When the contaminants cannot be identified and no guidance is available, the hazard is considered

unknown and the atmospheres shall be considered IDLH, and only breathable gas supplying RPD with

the highest APF or protection class shall be selected.

The foreseeable worst-case airborne exposure concentrations of contaminants in the atmosphere

shall be determined. If the contaminant concentration is unknown and if there is a national or industry

guidance document that is specific to the task, then the assigned protection factors (APF) or the

recommended Protection Level shall be chosen.

The occupational exposure limits or the safe exposure levels shall be identified for contaminants

where available. Where no OEL is published for the contaminant and there are no national or local

regulations that relate to the contaminant, then control-banding method may offer a solution; see C.1.3.

If the control banding method cannot be used, then select an RPD with the highest protection class.

Does the potential for IDLH conditions exist? An IDLH atmosphere is one that poses an immediate

threat to life, would cause irreversible adverse health effects, or would impair an individual’s ability to

escape. It is an atmosphere where the potential exists where one could not escape without the aid of an

5 Situations for using RPD

RPD is considered to be at the bottom of the hierarchy of control measures and should only be used

after an acceptable case for its use has been established by way of an appropriate risk assessment. RPDs

are used to further reduce inhalation exposures to hazardous atmospheres:
— when sufficient engineering and administrative controls are lacking;

— when these controls are not reasonably practical (maintenance, escape or rescue work);

— prior to implementing or improving a control measure.
6 RPD programme
6.1 General

The RPD programme includes processes for selecting, using and maintaining RPD to ensure adequate

protection to the wearer.

Prior to using RPD, it is essential to establish a written RPD programme. The RPD programme needs to

be understood by all persons within the organization, as appropriate.
6.2 RPD programme elements
The RPD programme consists of the following elements:
a) roles and responsibilities (see 6.3);
b) RPD programme implementation (see 6.4);
c) risk assessment (see Clause 7);
d) selection procedures (see Clause 7);
e) medical assessment (see 7.3.3.2);
f) fit testing (see 7.4);
g) training (see 7.5);
h) use (see 7.6);
i) maintenance procedures (see 7.7);
j) storage (see 7.8);
k) programme review (see 7.9);
l) records and record keeping (see 7.10).

---------------------- Page: 10 ----------------------
ISO/TS 16975-1:2016(E)
6.3 Roles and responsibilities
6.3.1 General

All persons involved in the respiratory protection programme shall be competent in their area of

responsibility within the RPD programme and maintain the appropriate knowledge, experience and

training to effectively carry out their duties.
6.3.2 Employer
The employer shall
— be responsible for the entire RPD programme,
— define, implement and document the RPD programme,

— provide adequate resources and organization to ensure the programme’s continued effectiveness, and

— assign an RPD programme administrator.
The employer and the programme administrator may be the same person.
6.3.3 RPD Programme administrator

The programme administrator shall be responsible for effective management of the entire RPD

programme.
6.3.4 Wearer
The wearer shall be responsible for
— using the RPD in accordance with the instructions and training received,
— reporting of any damage, defects or non-function of the RPD provided, and

— reporting any physical or medical limitations or changes that can impact their ability to wear and

use the RPD correctly.
6.4 RPD programme implementation

The RPD programme shall be implemented, evaluated and updated as necessary to reflect those

changes in workplace conditions that affect RPD use.
7 Risk assessment and RPD selection
7.1 General

A risk assessment is essential for the correct selection and use of RPD. It shall be conducted by a

competent person before RPD is used for routine work, emergency work, rescue (including response to

catastrophic incidents) or escape.
The risk assessment shall be conducted
— prior to the start of all new work processes,
— if the work conditions change,
— for new wearers, not covered by the existing suitability assessments, and

— periodically thereafter, at least annually or in accordance with national or local regulations.

ISO/TS 16975-1:2016(E)

The RPD selection procedure, shown in the following flow charts in 7.2 and described in 7.3, uses the

information gathered from the risk assessment which shall include the following.

a) The Hazard Assessment flow charts identify the nature of the hazard, e.g. oxygen deficiency,

contaminant level, Immediately Dangerous to Life or Health (IDLH).

b) The Adequacy Assessment flow chart determines the protection level required for the hazard.

c) The Suitability Assessment flow charts identify the factors to consider when selecting the RPD that

meets the needs of the wearer and is appropriate for the task and the environment.

d) The special application flow chart identifies the minimum work rates and the minimum protection

classes of the various classes within the special applications.

This is an example of a navigation marker. These navigation markers precede text and are cross

referenced in the flow charts. All markers are listed sequentially in 7.3. In addition, a flow chart may

contain markers out of sequence. Follow the flow charts in the order given above and always begin at

the top block. Read the contents of each block in sequence and follow the decision logic.

The diamond shape indicates that a decision shall be made in order to proceed. Answer each with

a “Yes” or “No” response and follow the arrow to the next block.

The rhomboid shape provides data that leads to the final specification and class of suitable RPD.

The “wave shape” is an instruction to document the output of the suitability assessment.

The irregular pentagon is an instruction to go to the next flow chart.
The cylinder is an indication of the mode of operation.

Record the outcome of the selection procedure in accordance with ISO/TS 16975-2. The example of the

selection record sheet can be used (see Annex J).

7.3 Selection procedure
7.3.1 Hazard assessment
7.3.1.1 General

The hazard assessment shall identify the nature of the hazard(s) present for which respiratory

protection may be required.
7.3.1.1.1 Oxygen deficiency

The potential for oxygen deficiencies shall be considered. When national or local regulations that

relate to oxygen deficiency levels exist, these should be followed.
7.3.1.1.2 Identification of contaminants

The contaminant(s) likely to be present as gas, vapour or particle shall be identified.

All materials used, produced or stored, including raw materials, end products, by-products and wastes,

should be reviewed by assessing the work process and by referring to the safety data sheets (SDS).

From this review, the contaminant(s) that may be present in the workplace shall be identified.

National or local regulations that relate to specific contaminants (e.g. asbestos, lead, benzene) shall be

followed. If the contaminant is unknown and if there is a national or industry guidance document that

is specific to the task, then the assigned protection factors (APF) or the recommended Protection Level

shall be chosen.

When the contaminants cannot be identified and no guidance is available, the hazard is considered

unknown and the atmospheres shall be considered IDLH, and only breathable gas supplying RPD with

the highest APF or protection class shall be selected.

The foreseeable worst-case airborne exposure concentrations of contaminants in the atmosphere

shall be determined. If the contaminant concentration is unknown and if there is a national or industry

guidance document that is specific to the task, then the assigned protection factors (APF) or the

recommended Protection Level shall be chosen.

The occupational exposure limits or the safe exposure levels shall be identified for contaminants

where available. Where no OEL is published for the contaminant and there are no national or local

regulations that relate to the contaminant, then control-banding method may offer a solution; see C.1.3.

If the control banding method cannot be used, then select an RPD with the highest protection class.

Does the potential for IDLH conditions exist? An IDLH atmosphere is one that poses an immediate

threat to life, would cause irreversible adverse health effects, or would impair an individual’s ability to

escape. It

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 editorial rules of the

ISO/IEC Directives, Part 2. www.iso.org/directives

Introduction

This part of ISO 16975 contains the essential requirements for establishing and implementing a complete

respiratory protective device (RPD) programme for respiratory protective devices that meet the requirements

of the performance standards. It contains information on risk assessment, selection procedure, training, use

and maintenance.

Informative annexes provide additional guidance on how to implement such a programme.

The following definitions apply in understanding how to implement an ISO International Standard and other

normative ISO deliverables (TS, PAS, IWA).
 “shall” indicates a requirement
 “should” indicates a recommendation
 “may” is used to indicate that something is permitted

 “can” is used to indicate that something is possible, for example, that an organization or individual is able

to do something

3.3.1 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a requirement as an "expression in the

content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed and

from which no deviation is permitted."

3.3.2 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a recommendation as an “expression in

the content of a document conveying that among several possibilities one is recommended as particularly

suitable, without mentioning or excluding others, or that a certain course of action is preferred but not

necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated but

not prohibited.”

utilisés pour réduire au minimum les expositions par inhalation dans des atmosphères dangereuses,

par exemple:

— en l’absence de mesures de prévention techniques et administratives suffisantes;

— lorsque ces mesures de prévention ne sont pas raisonnablement possibles (travaux de maintenance,

d’évacuation, de sauvetage);
— avant la mise en œuvre ou l’amélioration d’une mesure de prévention.

6.3 Rôles et responsabilités
6.3.1 Généralités

Toutes les personnes impliquées dans le programme de protection respiratoire doivent être

compétentes dans leur domaine de responsabilité, tel que le définit le programme APR, et maintenir le

niveau de connaissances, d’expérience et de formation nécessaire pour mener à bien leur mission.

6.3.2 Employeur
L’employeur doit:
— assurer la responsabilité de l’intégralité du programme APR;
— définir, mettre en œuvre et documenter le programme APR;

— fournir les ressources et l’organisation adéquates pour garantir l’efficacité durable du programme; et

— désigner un administrateur de programme APR.
L’employeur peut assurer lui-même le rôle d’administrateur du programme.
6.3.3 Administrateur du programme APR

L’administrateur du programme doit assurer la responsabilité de la gestion efficace de l’ensemble du

programme APR.
6.3.4 Porteur
Le porteur doit être tenu:

— d’utiliser l’APR conformément aux instructions et à la formation qu’il a reçues;

7 Évaluation du risque et choix de l’APR
7.1 Généralités

Une évaluation de risque est indispensable pour garantir un choix et une utilisation appropriés de

l’APR. Cette évaluation doit être menée par une personne compétente avant que l’APR ne soit utilisé

dans le cadre d’activités courantes ou d’interventions d’urgence, de sauvetage (y compris en réponse à

des événements catastrophiques) ou d’évacuation.
L’évaluation du risque doit être effectuée:
— avant le démarrage de tout nouveau procédé de travail;
— en cas de changement des conditions de travail;

— dans le cas de nouveaux porteurs non couverts par les évaluations d’adaptation existantes; et

— périodiquement ensuite, au moins à une fréquence annuelle ou selon les réglementations nationales

ou locales applicables.

La procédure de sélection d’APR, illustrée dans les diagrammes du paragraphe 7.2 ci-après et décrite

en 7.3, s’appuie sur les informations recueillies à l’issue de l’évaluation du risque, qui doit couvrir les

points suivants:

a) Les diagrammes d’évaluation du danger identifient la nature du danger, par exemple,

appauvrissement en oxygène, niveau de contaminant, danger immédiat pour la vie ou la

santé (IDLH).

b) Le diagramme d’évaluation de l’adéquation détermine le niveau de protection requis en fonction

du danger.

c) Les diagrammes d’évaluation de l’adaptation identifient les facteurs à prendre en compte lors du

choix d’un APR capable de répondre aux besoins du porteur tout en étant approprié à la tâche et à

l’environnement.

d) Le diagramme des applications particulières identifie les rythmes de travail minimaux et les

classes de protection minimales des différentes classes d’applications particulières.

Ce symbole constitue un exemple de marqueur de navigation. Ces marqueurs de navigation

précèdent le texte et sont référencés dans les diagrammes. Tous les marqueurs sont décrits, par

séquence, au paragraphe 7.3. De plus, un diagramme peut contenir des marqueurs hors séquence.

Suivre les diagrammes dans l’ordre indiqué ci-dessus veillant toujours à commencer par le haut. Lire le

contenu de chaque bloc dans l’ordre en suivant la logique décisionnelle.

Le losange indique qu’une décision doit être prise avant de poursuivre. Répondre par «Oui» ou par

«Non» et suivre la flèche jusqu’au bloc suivant.

Le parallélogramme fournit des données qui conduisent à la spécification finale et à la classe de

l’APR approprié.

La forme «ondulée» indique qu’il faut documenter le résultat de l’évaluation de l’adaptation.

Les pentagones irréguliers indiquent qu’il faut passer au diagramme suivant.
Le cylindre est une indication du mode de fonctionnement.

Enregistrer le résultat de la procédure de sélection conformément à l’ISO/TS 16975-2. Il est possible

d’utiliser pour cela l’exemple de fiche de sélection (voir Annexe J). Si le tableau de l’Annexe J recommande

de demander l’avis d’un spécialiste, les fabricants/fournisseurs d’APR et les conseillers en santé et

sécurité constituent une bonne source d’information.
