Procedure for the assessment of the exposure to electromagnetic fields of workers bearing active implantable medical devices - Part 1: General

This European Standard provides a procedure to assess the risk to workers bearing one or more active
implantable medical devices from exposure to electric, magnetic and electromagnetic fields at a workplace. It
describes how a general risk assessment should be performed and determines whether it is necessary to
carry out a detailed risk assessment.
NOTE 1 This European Standard does not cover indirect effects caused by non active implants.
NOTE 2 The risk of human exposure to EMF considered is only due to malfunctioning of AIMD. Possibilities of AIMD
contribution to the risk, e.g. local modification of the distribution of EMF produced by external source or production of
own EMF, are covered by the respective product standards for the AIMD.
Based on specific workplace standards it can be determined whether preventive measures/actions need to
be taken to comply with the provisions of Directive 2013/35/EU. The work situation covered is considered to
be under normal working conditions including normal operation, maintenance, cleaning and other situations
being part of the normal work.
The frequencies covered are from 0 Hz to 300 GHz.
The European Parliament and Council Directive 2013/35/EU will be transposed into national legislation in all
the EU member countries. It is recommended that users of this standard consult the national legislation
related to this transposition in order to identify the national regulations and requirements. These national
regulations and requirements may have additional requirements that are not covered by this standard and
take precedence.
NOTE 3 Performance requirements with respect to active implantable medical devices are excluded from the Scope
of this standard. These are defined in the relevant particular standards for active implantable medical devices.
The risk assessment described in this standard is only required if an AIMD-Employee is present.
Active Implantable Medical Devices (AIMDs) are regulated by Directive 90/385/EEC and the amendments to
it.
NOTE 4 Product standards EN 45502–1 and of the EN 45502–2-X series describe the product requirements for
different kinds of AIMDs. Different kinds of AIMDs are e.g. pacemaker (EN 45502–2–1), implantable cardioverter
defibrillators (EN 45502–2–2), cochlear implants (EN 45502–2–3), implantable neurostimulators (ISO 14708-3),
implantable infusion pumps (ISO 14708-4).
In situations where the risk assessment following this standard does not lead to a conclusion,
complementary provisions for the assessment of workers exposure for different kinds of AIMDs are given in
particular standards for these specific AIMDs (see Figure 1).

Postopek ocenjevanja izpostavljenosti delavcev z aktivnimi medicinskimi vsadki elektromagnetnim poljem - 1. del: Splošno

Ta evropski standard določa postopek za oceno tveganja za delavce, ki imajo enega ali več aktivnih medicinskih vsadkov, v povezavi z izpostavljenostjo električnim, magnetnim in elektromagnetnim poljem na delovnem mestu. Opisuje način izvajanja splošnega ocenjevanja tveganja in določa, ali je treba izvesti podrobno ocenjevanje tveganja.
OPOMBA 1: Ta evropski standard ne zajema posrednih vplivov, ki jih povzročajo neaktivni vsadki.
OPOMBA 2: Obravnavano je tveganje izpostavljenosti osebe elektromagnetnemu polju, ki je izključno posledica okvare aktivnega medicinskega vsadka. Možnosti aktivnega medicinskega vsadka za povečanje tveganja, npr. lokalne spremembe porazdelitve elektromagnetnega polja, ki jih povzroči zunanji vir, ali ustvarjanje lastnega elektromagnetnega polja, so zajete v ustreznih standardih za aktivne medicinske vsadke. Na podlagi posameznih standardov za delovna mesta je mogoče ugotoviti, ali so za namene skladnosti z določbami Direktive 2013/35/EU potrebni preventivni ukrepi/dejanja. Zajete delovne razmere se obravnavajo kot običajni delovni pogoji, vključno z običajnim delovanjem, vzdrževanjem, čiščenjem in drugimi okoliščinami, ki so del običajnega opravljanja dela.
Zajet frekvenčni razpon je od 0 Hz do 300 GHz.
Direktiva 2013/35/EU Evropskega parlamenta in Sveta bo prenesena v nacionalno zakonodajo vseh držav članic EU. Priporočljivo je, da uporabniki tega standarda upoštevajo nacionalno zakonodajo, povezano s tem prenosom, ter se seznanijo z nacionalni predpisi in zahtevami. Ti nacionalni predpisi in zahteve lahko vključujejo dodatne zahteve, ki niso zajete v tem standardu, in imajo prednost.
OPOMBA 3: Zahtevane lastnosti v zvezi z aktivnimi medicinskimi vsadki so izključene s področja uporabe tega standarda in so opredeljene v ustreznih standardih za aktivne medicinske vsadke.
Ocena tveganja, opisana v tem standardu, je zahtevana samo, če je prisoten uporabnik aktivnega medicinskega vsadka.
Aktivne medicinske vsadke (AIMD) ureja Direktiva 90/385/EGS in njena dopolnila.
OPOMBA 4: Standard za proizvode EN 45502-1 in skupina standardov EN 45502-2-X opisujejo zahteve za različne vrste aktivnih medicinskih vsadkov. Različne vrste aktivnih medicinskih vsadkov so npr. srčni spodbujevalnik (EN 45502-2-1), kardioverter defibrilatorji za vsaditev (EN 45502-2-2), polžasti vsadki (EN 45502-2-3), nevrostimulatorji za vsaditev (ISO 14708-3), infuzijske črpalke za vsaditev (ISO 14708-4).
Če ocena tveganja v skladu s tem standardom ne privede do zaključka, so v posameznih standardih za ustrezne aktivne medicinke vsadke podane dodatne določbe za oceno izpostavljenosti delavcev za te vrste aktivnih medicinskih vsadkov (glej sliko 1).

SIST EN 50527-1:2017
EN 50527-1:2016 (E)

The human exposure to electromagnetic fields (EMF) is regulated at European level in a twofold way. For the

general public, Council Recommendation 1999/519/EC stipulates maximum exposure limits based on the

ICNIRP guidelines. Nevertheless, Article 153 of the European treaty grants the member states the right to

set stricter limit values in their obligation to govern public health and safety.

For Occupational Exposure Directive 2013/35/EU as individual physical agents directive issued under the

Occupational Health and Safety Framework Directive 89/391/EEC sets the minimum health and safety

requirements based on the maximum occupational exposure limits of the ICNIRP guidelines.

Common to the European Recommendation and Directive limiting human exposure to EMF and to the

ICNIRP guidelines is the fact that their limit values are based on direct effects of EMF exposure to the human

body. For the low frequency range the induced current density in the nervous system or induced voltages

across membranes are the limiting factors whereas in the higher frequency area tissue heating by absorption

needs to be limited.

The Occupational Exposure Directive 2013/35/EU in Article 4.5 additionally obliges the employer to

investigate during the risk assessment process indirect effects like interference with medical electronic

equipment and devices (including cardiac pacemakers and other implanted devices).

Risks to the bearer may be caused by different effects:

— a conductive implant may directly cause an increase of current density in the body tissue surrounding

the implant, or

— the behaviour of the device may be interfered with (for examples see D.8 in Annex D of this standard).

The possibility of interference to the device depends on the EMF exposure level and the electromagnetic

performance of the device, its settings and the method of implantation. The clinical relevance of interference

may depend on the duration of exposure.

The main objective of this standard is to describe how a risk assessment for an employee bearing one or

more active implantable medical devices (AIMD-Employee) in electromagnetic fields may be performed. A

first step consists of a simplified risk analysis, followed where necessary, by a more extensive risk

assessment.

Directives 90/385/EEC and 2007/47/EC on medical devices requires that AIMDs are designed and

manufactured in such a way as to remove or minimize as far as possible risks connected with reasonably

foreseeable environmental conditions such as magnetic fields, external electromagnetic interference effects,

and electrostatic discharge.

EN 50499 originally introduced a concept of identifying equipment not likely to cause exposure to EMF

above the limit values. This standard follows this approach but some of the identified equipment for general

purpose assessment needs further analysis for AIMD-Employee. For higher frequency exposures, human

body tissue has a time constant with respect to heating effects and a high immunity to pulsating exposure,

whereas the electronic circuitry of an implant may be interfered with even by short pulses.

1 Scope

This European Standard provides a procedure to assess the risk to workers bearing one or more active

implantable medical devices from exposure to electric, magnetic and electromagnetic fields at a workplace. It

describes how a general risk assessment should be performed and determines whether it is necessary to

carry out a detailed risk assessment.

NOTE 1 This European Standard does not cover indirect effects caused by non active implants.

NOTE 2 The risk of human exposure to EMF considered is only due to malfunctioning of AIMD. Possibilities of AIMD

contribution to the risk, e.g. local modification of the distribution of EMF produced by external source or production of

own EMF, are covered by the respective product standards for the AIMD.

Based on specific workplace standards it can be determined whether preventive measures/actions need to

be taken to comply with the provisions of Directive 2013/35/EU. The work situation covered is considered to

be under normal working conditions including normal operation, maintenance, cleaning and other situations

being part of the normal work.
The frequencies covered are from 0 Hz to 300 GHz.

The European Parliament and Council Directive 2013/35/EU will be transposed into national legislation in all

the EU member countries. It is recommended that users of this standard consult the national legislation

related to this transposition in order to identify the national regulations and requirements. These national

regulations and requirements may have additional requirements that are not covered by this standard and

take precedence.

NOTE 3 Performance requirements with respect to active implantable medical devices are excluded from the Scope

of this standard. These are defined in the relevant particular standards for active implantable medical devices.

The risk assessment described in this standard is only required if an AIMD-Employee is present.

Active Implantable Medical Devices (AIMDs) are regulated by Directive 90/385/EEC and the amendments to

it.

NOTE 4 Product standards EN 45502–1 and of the EN 45502–2-X series describe the product requirements for

different kinds of AIMDs. Different kinds of AIMDs are e.g. pacemaker (EN 45502–2–1), implantable cardioverter

defibrillators (EN 45502–2–2), cochlear implants (EN 45502–2–3), implantable neurostimulators (ISO 14708-3),

implantable infusion pumps (ISO 14708-4).

In situations where the risk assessment following this standard does not lead to a conclusion,

complementary provisions for the assessment of workers exposure for different kinds of AIMDs are given in

particular standards for these specific AIMDs (see Figure 1).

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated references,

the latest edition of the referenced document (including any amendments) applies.

EN 45502-1:2015, Implants for surgery — Active implantable medical devices — Part 1: General

requirements for safety, marking and for information to be provided by the manufacturer

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
AIMD-Employee
employee bearing one or more AIMDs
3.2
interference distance

distance identified for a piece of equipment, outside of which distance an AIMD-Employee can work normally

Note 1 to entry: This is also used in the same way to identify the closest distance an item of portable equipment can

be, while the AIMD-Employee can work normally. At closer distances the AIMD-Employee may still be allowed to work

normally, but this requires a specific assessment for that situation; or transient exposure may be possible provided no

warnings against this have been received by the AIMD-Employee.

Note 2 to entry: Sometimes this distance is quoted as a “safety distance” but it should not be confused with the safety

distances identified for general EMF exposure of all employees in the workplace. At these general EMF safety distances

the fields may be high enough to cause response changes or other effects to an AIMD.

3.3
medical device

instrument, apparatus, appliance, software, material or other article, whether used alone or in combination,

together with any accessories, including the software intended by its manufacturer to be used specifically for

diagnostic and/or therapeutic purposes and necessary for its proper application, intended by the

manufacturer to be used for human beings for the purpose of:
• diagnosis, prevention, monitoring, treatment or alleviation of disease,

• diagnosis, monitoring, treatment, alleviation of or compensation for an injury or handicap,

• investigation, replacement or modification of the anatomy or of a physiological process,

• control of conception,

and which does not achieve its principal intended action in or on the human body by pharmacological,

immunological or metabolic means, but which may be assisted in its function by such means

[SOURCE: Directive 2007/47/EC]
3.4
active medical device

medical device relying for its functioning on a source of electrical energy or any source of power other than

that directly generated by the human body or gravity

3.6
responsible physician

physician responsible for the implantation and/or follow up monitoring of the AIMD

3.7
transient exposure
exposure to electromagnetic fields in the order of seconds which:
• is not continuous; i.e. comes to an end or reduces to non-influential levels;
• does not damage the AIMD;

• only leads to acceptable response of the AIMD based on the advice from the responsible physician (for

example by general guidance or by a specific warning) and/or described in the documentation

accompanying the AIMD

Note 1 to entry: Such exposure may be caused by the electromagnetic field being temporary or by the exposed person

moving within, or through, an electromagnetic field.
3.8
workplace

location where workers have access as part of their duties or during their breaks and all pathways that need

to be used to reach these
4 Risk assessment
4.1 Risk assessment procedure
4.1.1 Introduction

The Occupational Health and Safety Framework Directive 89/391/EEC requires in Article 15 about Risk

groups:

“Particularly sensitive risk groups must be protected against the dangers which specifically affect them.”

The interference of EMF with an implanted AIMD is identified as being an indirect effect causing particular

risk within the scope of Article 4.5 of Directive 2013/35/EU.
Figure 2 gives a schematic overview of the risk assessment process.

For some types of workplaces the EMF risk assessment is covered by a specific workplace standard. If such

a standard is used for risk assessment then the presentation of the result should normally be done in

accordance with that standard.

Special considerations are often needed when it comes to the assessment of work that takes place outside

the employer’s premises. It is generally advised that the employer trains AIMD-Employees to be aware of

particular risks that they might encounter during their work. This could be, for example, in situations where

craftsmen like bricklayers, plumbers and carpenters do maintenance work on chimneys, rooftops, etc. where

radio transmission or other transmitting antennas could be installed.

AIMD-Employees should be instructed on how to deal with such equipment in a safe manner. Generally this

means that AIMD-Employees are informed about the interference distances or zones of such equipment. If

the safety information is not provided in a sign at the site, it can be requested from the owner of the

---------------------- Page: 10 ----------------------
SIST EN 50527-1:2017
EN 50527-1:2016 (E)

equipment. However, it is the employer’s responsibility that AIMD-employees have the right information on

every workplace that they visit.
4.1.2 Workplace equipment
