Foreword

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International

Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies

casting a vote.

In exceptional circumstances, when a technical committee has collected data of a different kind from

that which is normally published as an International Standard (‘state of the art’, for example), it may

decide by a simple majority vote of its participating members to publish a Technical Report. A Technical

Report is entirely informative in nature and does not have to be reviewed until the data it provides are

considered to be no longer valid or useful.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO/TR 18690 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 161, Foot and leg protectors, in collaboration with ISO Technical Committee ISO/TC 94, Personal

safety — Protective clothing and equipment, Subcommittee SC 3, Foot protection, in accordance with the

agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO/TR 18690:2006), which has been

technically revised.

6 Selection of PPE footwear
6.1 Risk assessment
6.1.1 General

Statistics show that slip is the most common hazard in most workplaces. Slip resistance should therefore

be the first property to be considered when selecting footwear as PPE.

Employers and self-employed people should assess the risks from their work activities. Every effort

should be made to reduce risks to a minimum before considering the use of PPE. If the risks cannot be

eliminated by other methods, personal protective equipment should be used. It is important to select the

correct type of PPE footwear in respect of the risk. The protection required in the work place determines

the type of footwear to be chosen. The properties of PPE Footwear can be combined to provide protection

against more than one hazard, for example footwear can have a toe cap and be slip resistant.

---------------------- Page: 16 ----------------------
SIST-TP CEN ISO/TR 18690:2013
ISO/TR 18690:2012(E)

Prior to the selection and use of PPE footwear or leg protector the employer should assess the working

conditions, especially the type and extent of the hazards, duration of the hazard and personal requisites

of the wearer.
6.1.2 Risk analysis

Generally, exposure to health and safety risks is always present in work activities. Therefore, the

implementation of collective protection systems is required, and when the residual risk cannot be

avoided and/or reduced, PPE has to be used.

Before selecting and using safety or occupational footwear, the employer should carefully evaluate the

working conditions, including:
— risk type and nature;
— risk duration and frequency;
— individual features of the worker to be protected.

In this context, the human factor-related risk is of particular importance. The term encompasses all risk

factors connected with the worker’s psycho-physical state, incapacity, recklessness, lack of training and,

in general, behaviour that is inappropriate in the work context. The absence of theoretical and practical

training, as well as the inability to handle certain work situations, are the most frequent human factor-

related causes of accidents. Human factor-related risks at work should be duly analysed so as to be

subsequently eliminated and/or reduced.
6.1.3 Types of risk

In his work activities, the worker is exposed to residual risks of various natures, which can be eliminated

or reduced to an acceptable level. The elimination or reduction of such risks should be performed through

the implementation of suitable safety footwear which should always be correctly used and maintained,

according to the manufacturer’s instructions, within qualitative limits that do not compromise the

protective characteristics of the footwear and in accordance with its intended use, so as not to incur

further risks derived from the footwear itself.
Risks covered by the use of safety footwear:
— mechanical;
— electrical;
— thermal;
— chemical.
Risks resulting from the use of inappropriate or damaged safety footwear:
— discomfort, interference with work activities;
— accidents and health risks;
— insufficient protection, etc.
6.1.4 Exposure to risks

Risk assessment should be able to identify the presence, at any time throughout the work day, of serious

health risks, that is risks that may incur death or permanent health damage and of which the worker

may not be opportunely aware, as well as any other health and safety risks.
© ISO 2012 – All rights reserved 7
---------------------- Page: 17 ----------------------
SIST-TP CEN ISO/TR 18690:2013
ISO/TR 18690:2012(E)

The exposure to risks at any time, throughout the work day and in particular to risks incurring death or

permanent health damage and of which the worker is not opportunely aware, should be null or limited

to the minimum.

The use of suitable safety footwear depends on the expected type of danger. Although the types of risk

may be known, it is not always possible to foresee an accident. For this reason, safety footwear should

be used as protection in all situations in which risks cannot be excluded.
6.1.5 Risk reduction

In order to reduce risks, priority should be given to technical-organizational actions aimed at the

elimination or sufficient reduction of risks at the source and at safeguarding the workers by means of

collective protection.

In cases where such collective means do not ensure the prevention and/or reduction of health and safety

risks to an acceptable level, suitable safety footwear or, in general, suitable PPE, should be used.

Work activities should be performed by qualified, informed and trained personnel, while the presence

of unauthorized individuals should be avoided. Particular attention should be paid to risks connected

with the human factor.

Figure 3 shows the methodology of identification, elimination and reduction of specific occupational risks.

Moreover, the PPE should:

— be suitable for the risks to be prevented, without constituting an additional risk itself;

— be suitable for the conditions in the workplace;
— be adequate to the worker’s ergonomic or health requirements;
— be adaptable to the user’s needs.

In the case of multiple risks requiring a simultaneous use of more PPE, such equipment should be

compatible and should maintain its individual efficacy in the face of respective risks.

NOTE 1 The methodological diagram is valid for the assessment of one specific risk only.

NOTE 2 The phrase ‘Danger identification and risk analysis’ includes the techniques of danger assessment and

risk analysis that provide reliable results.

NOTE 3 ‘Selection and adoption of organizational and/or technical measures’ and ‘Selection and adoption of

collective protection equipment’ can be performed both in parallel and in a series, and with an exchange of information.

identification, risk analysis, elimination, replacement, selection and adoption of protective

measures
6.1.6 Aid for risk assessment

The use of every item of footwear and leg protection should depend on the type of expected hazard (see

Table 8). Although the types of hazard are known, it cannot be predicted when they actually occur.

Prior to selection and use the employer should perform an assessment of the foot and leg protection

he/she has in mind to determine whether they:
a) are type tested (labelled with the appropriate symbol and other markings);

b) offer protection against the hazards to be averted without inherently presenting a greater hazard;

c) are suitable for the relevant workplace conditions;
d) fulfil the ergonomic requirements and the health requisite of the wearer;

e) can be adapted to the individual wearer.

The employer should ensure that every wearer is provided with his/her personal foot or leg protection

for his/her personal use.

While selecting PPE footwear, an optimal protection in respect of ergonomic features should be taken

into account. Over-protection should be avoided. Ergonomic features of the footwear for example. mass,

rigidity of soling, water-vapour permeability should be considered,
