COMMUNICATION FROM THE COMMISSION

on the Guidelines on the assessment of the chemical, physical and biological agents and
industrial processes considered hazardous for the safety or health of pregnant workers and
workers who have recently given birth or are breastfeeding (Council Directive 92/85/EEC)

COMMUNICATION FROM THE COMMISSION

on the Guidelines on the assessment of the chemical, physical and biological agents and
industrial processes considered hazardous for the safety or health of pregnant workers and
workers who have recently given birth or are breastfeeding (Council Directive 92/85/EEC)

SUMMARY

Article 3(1) of Council Directive 92/85/EEC of 19 October 1992 (OJ L 348 of 28 November
1992, p. 1) on the implementation of measures to encourage improvements in the safety and
health at work of pregnant workers and workers who have recently given birth or are
breastfeeding (tenth individual Directive within the meaning of Article 16(1) of Directive
89/391/EEC) provides that:

“In consultation with the Member States and assisted by the Advisory Committee on Safety,
Hygiene and Health Protection at Work, the Commission shall draw up guidelines on the
assessment of
the chemical, physical and biological agents and industrial processes
considered hazardous for the safety or health of workers within the meaning of Article 2.

The guidelines referred to in the first subparagraph shall also cover movements and postures,
mental and physical fatigue and other types of physical and mental stress connected with the
work done by workers within the meaning of Article 2.”

Pursuant
to Article 3(2), the purpose of the guidelines is to serve as a basis for the
assessments referred to in Article 4(1), which in turn provides that “For all activities liable to
involve a specific risk of exposure to the agents, processes or working conditions of which a
non-exhaustive list is given in Annex I, the employer shall assess the nature, degree and
duration of exposure, in the undertaking and/or establishment concerned, of workers within
the meaning of Article 2, either directly or by way of the protective and preventive services
referred to in Article 7 of Directive 89/391/EEC, in order to:

–

–

assess any risks to the safety or health and any possible effect on the pregnancy or
breastfeeding of workers within the meaning of Article 2,

decide what measures should be taken”.

The Commission, in consultation with the Member States and assisted by the Advisory
Committee on Safety, Hygiene and Health Protection at Work, has prepared the Guidelines
set out below.

The Commission attaches the greatest importance to all measures designed to protect the
health and safety of workers, and notably certain groups of particularly vulnerable workers
such as is clearly the case of pregnant workers and workers who have recently given birth or
are breastfeeding - all the more so because the risks to which they may be exposed are liable
to damage not only their own health but also that of their unborn or newborn children, given
that there is a very close physiological and indeed emotional link between mother and child.

this Communication constitutes an effective and
Hence the Commission considers that
eminently practical tool which can serve as guidance in assessing the risks to the health and

2

safety of pregnant workers and workers who have recently given birth or are breastfeeding.
On the basis of this assessment it will be possible to take more effective measures.

For these reasons the Commission will see to it that these guidelines are disseminated as
widely as possible by the bodies and persons responsible for health and safety at work.

INTRODUCTION

Pregnancy should be regarded not as an illness but as part of everyday life. Protection of
health and safety in respect of pregnant women can often be achieved by applying
existing rules and procedures in the relevant areas. Many women work while they are
pregnant, and many return to work while they are still breastfeeding. However, some
hazards in the workplace may affect the health and safety of new and expectant mothers
and of their children. A pregnancy entails great physiological and psychological
changes. The hormonal balance is very sensitive and exposures capable of disrupting it
can lead to complication, possibly resulting, for example, in miscarriage.

Conditions which may be considered acceptable in normal situations may no longer be
so during pregnancy.

The approach to risk assessment

Risk assessment is a systematic examination of all aspects of work in order to identify
the probable causes of injuries or damage and to establish how these causes can be
contained in order to eliminate or reduce risks.

In accordance with the requirements of Directive 92/85/EEC, assessment must comprise
at least three phases:

1.

2.

3.

identification of hazards (physical, chemical and biological agents; industrial
fatigue; other
processes; movements and postures; mental and physical
physical and mental burdens);

identification of worker categories (exposed pregnant workers, workers who
have recently given birth or workers who are breastfeeding);

risk assessment in both qualitative and quantitative terms.

Hazard: the intrinsic property or ability of something (e.g. work materials, equipment,
methods and practices) with the potential to cause harm;

Risk: the likelihood that the potential for harm will be attained under the conditions of
use and/or exposure, and the possible extent of the harm.

As regards point 1 (identification of hazards), extensive data are already available in
respect of physical agents (including ionising radiation) and chemical and biological
agents.

With specific reference to chemical agents, Council Directive 67/548/EEC, as most
recently amended by Commission Directive 2000/33/EC on the approximation of the
laws, regulations and administrative provisions relating to the classification, packaging
and labelling of dangerous substances makes provision for the following risk phrases
for substances and preparations:

–
–
–

possible risks of irreversible effects (R40);
may cause cancer (R45);
may cause heritable genetic damage (R46);

6

–
–
–
–

may cause cancer by inhalation (R49);
may cause harm to the unborn child (R61);
possible risk of harm to the unborn child (R63);
may cause harm to breastfed babies (R64).

In connection with the assessment of existing substances and with the work of the
SCOEL (Scientific Committee for Occupational Exposure Limits), the Commission has
also produced a series of documents partly concerned with the subject.

Point 2 (identification of exposed worker category). Whereas there is no difficulty
targeting workers who have recently given birth or are breastfeeding, this does not apply
in the case of pregnant workers. There is a period of between 30 and 45 days during
which a worker may not be aware that she is pregnant and is therefore unable or
reluctant to inform her employer. However, some agents do exist, especially physical
and chemical agents, which may cause harm to the unborn child during the period
immediately following conception, which means that appropriate preventive measures
are essential. The problem is not easy to solve, in that it requires special care to be taken
in respect of all workers by reducing their exposure to these harmful agents.

Point 3 (qualitative and quantitative risk assessment) represents the most delicate phase
in the process, in that the person carrying out the assessment must be competent and
take due account of relevant information, including information from the pregnant
woman herself or her advisors, in applying appropriate methods in order to be able to
conclude whether or not the hazard identified entails a risk situation for workers.

Legal background

Article 3(1) of Council Directive 92/85/EEC of 19 October 1992 (OJ No L 348 of 28
November 1992, p. 1) on the introduction of measures to encourage improvements in
the safety and health at work of pregnant workers and workers who have recently given
birth or are breastfeeding (10th individual Directive within the meaning of Article 16(1)
of Directive 89/391/EEC) requires the Commission to draw up risk assessment
guidelines in consultation with the Member States and assisted by the Advisory
Committee on Safety, Hygiene and Health Protection at Work.

These guidelines will serve as a basis for the assessment referred to in Article 4(1) of
the same Directive, which is an integral part of the assessment of the risks referred to in
Article 9 of the “framework” Council Directive 89/391/EEC on the introduction of
measures to encourage improvement in the safety and health at workers at work, which
states that:

"For all activities liable to involve a specific risk of exposure to the agents, processes or
working conditions of which a non-exhaustive list in given in Annex I, the employer
shall assess the nature, degree and duration of exposure, in the undertaking and/or
establishment concerned, of workers within the meaning of Article 2, either directly or
by way of the protective and preventive services referred to in Article 7 of “framework”
Council Directive 89/391/EEC, in order to:

–

assess any risks to the safety or health and any possible effect on the pregnancy
or breastfeeding of workers within the meaning of Article 2,

7

–

decide what measures should be taken."

It should be noted that:

–

–

the employer is obliged to carry out a risk assessment for all female workers
who fulfil the criteria laid down in Article 2 of the Directive (see definitions on
page 7). This includes those in the armed forces, the police, and certain specific
activities in the civil protection services;

the risk assessment for pregnant workers is an additional risk assessment which
is to be carried out
in accordance with the provisions of the framework
Directive.
This risk assessment must take into account the preventive aspects of the
framework Directive and should also at least refer to the potential risks to
pregnant workers, in so far as such risks are known (e.g. risks related to certain
chemicals, etc).

Previous measures connected with the present action

In 1993-94 the Commission produced a document entitled "Guidance on risk
assessment at work" [ISBN 97-727-4278-9]. This document is intended for the Member
States, to be used or adapted for the purposes of providing guidelines for employers,
workers, and any other parties who may be confronted with the practical aspects of rules
on risk assessment laid down in Council “framework” Directive 89/391/EEC on the
introduction of measures to encourage improvements in the safety and health of workers
at work, particularly Articles 6(3)(a) and 9(1)(a).

This document, which was published in 1996, constitutes an ideal basis for the
preparation of the guidelines referred to in Article 3(1) of Directive 92/85/EEC.

Specific points to be stressed

–

–

–

–

In order to take the framework Directive’s principle of prevention into account,
if the work is reorganised the risk assessment should be revisited and workers
adequately trained in the new organisation.

It is clear that the risk assessment referred to in this Directive is of a special
nature, as it is designed for a continually changing state which varies according
to each individual. In addition, it does not only affect the woman herself, but
also the unborn child and the breast-feeding baby. In branches where hazards
for reproduction and for pregnancy can be expected it is necessary to inform all
workers of the potential risks.

A one-off assessment may not be enough, as pregnancy is a dynamic process
and not a static condition. Furthermore, not only during the various stages of a
pregnancy but also after delivery, different risks can affect a woman and her
unborn or new-born child to a varying extent. The same also applies where
there is a change in working conditions, equipment or machines.

Medical advice, reports and certificates should take working conditions into
consideration. This is of particular relevance to an individual’s conditions (e.g.

8

morning sickness, heightened sensitivity or smells such as tobacco smoke,
etc.), which must be dealt with in strict confidentiality. The confidentiality
concerning a woman’s ‘condition’ must also ensure that an employer cannot
make it known that a woman is pregnant if she does not wish it to be known or
it could lead to a
if she does not consent to it. Otherwise, for instance,
considerable psychological strain for a woman who has already had one or
more miscarriages.

In certain circumstances it may be necessary to take steps (including limited
disclosure) to protect the woman’s health, safety and welfare, but this should
be done with the woman’s agreement following consultation.

Risk assessments should take due account of medical advice and the concerns
of the individual woman.

In respect of chemical hazards, it should be noted that occupational exposure
limits are set for adult workers, and women working with hazardous substances
should therefore be made aware of the additional risks that these substances
might pose to a unborn or breastfed child.

The directive allows for some flexibility for both the Member States and the
women themselves concerning maternity leave after birth (it grants compulsory
maternity leave of only two weeks but a total of at least 14 weeks (divided
between the time before and after giving birth) are granted). The various risks
which could arise for pregnant women or women who have just given birth
should be recorded and assessed.

Since the first trimester of pregnancy is the most vulnerable period in terms of
causing permanent damage to the unborn child, all necessary protection to the
mother and the unborn child should be started as soon as possible.

GENERAL DUTIES FOR EMPLOYERS CONCERNING RISK ASSESSMENT

The Directives require employers to assess risks to all workers, including new and
expectant mothers, and to avoid or control
the risk
assessment the employer should take into account existing occupational exposure limits.
Exposure limits for hazardous substances and other agents are normally set at levels
which should not put a pregnant or breastfeeding worker or her child at risk. In some
cases, there are lower exposure levels for pregnant workers than for other workers.

those risks. In carrying out

The PWD specifically requires employers to take particular account of risks to new,
breastfeeding and expectant mothers when assessing risks in the work activity. If the
risk cannot be avoided by other means, there will be a need to change the working
conditions or hours, or offer suitable alternative work. If that is not possible the worker
should be exempted from normal duties for as long as necessary to protect her health or
safety or that of her child.

What must an employer do?

9

In addition to carrying out the general risk assessment required by the Framework
Directive and Directive 92/85/EEC, on receiving notification that an employee is
pregnant an employer must assess the specific risks to that employee and take action to
ensure that she is not exposed to anything which will damage either her health or that of
her developing child.

The employer must:

–

assess the risk;

this means that he must determine:

the risks to which the pregnant woman or new mother who has recently given

(a)
birth or is breastfeeding is exposed;

(b)

the nature, intensity and duration of the exposure.

[[[[Appendix 1 contains references to some aspects of pregnancy which may require
adjustments to the work or the organisation thereof]]]]

–

–

remove the hazard and avoid or reduce the risk;

act to ensure there is no damage to health.

Damage to health means for this purpose any disease or damage to a person’s physical
or mental condition, or any possible effect on the pregnancy or the unborn or new-born
infant, or to women who have recently given birth.

If the assessment reveals that there is a risk, the employer must inform the woman about
the risk and explain the measures to be taken to ensure that the health and safety of the
woman or the developing child is not adversely affected.

Identifying the hazards

Physical, biological and chemical agents, processes and working conditions which may
affect the health and safety of new or expectant mothers are set out in the chapter on
specific hazards (see below). They include possible hazards listed in the Annexes to the
Directive on the health and safety of pregnant workers.

Many of the hazards included in the table are already covered by specific European
health and safety legislation, for example Council Directive 90/394 EEC (and its
amendments) on carcinogens, Council Directive 90/679/EEC (and its amendments) on
biological agents, Council Directive 80/1107/EEC on chemical, physical and biological
agents, which will be repealed upon transposal by the Member States of Directive
98/24/EC (before 5 May 2001), Council Directive 82/605/EEC on lead, Council
Directive 97/43/EURATOM on ionising radiation, Directive 90/269/EEC on the manual
handling of loads and Directive 90/270/EEC on display screen equipment. If any of
these hazards are present in the workplace, the employers should refer to the relevant
legislation for information on what they should do. Hazards may be multifactorial in
their effects.

Deciding who might be harmed, and how

The risk assessment may show that there is a substance, agent or work process in the
workplace that could damage the health or safety of new or expectant mothers or their
children. There is a need to bear in mind that there could be different risks depending on
whether workers are pregnant, have recently given birth or are breastfeeding. The
definition of workers includes, for example, maintenance and cleaning staff and there
may need to be cooperation between employers where employees of one are working,
e.g. as contractors, on the premises of another.

Informing employees of the risk

If the risk assessment does reveal a risk, the employers should inform all employees
concerned of the potential risks. They should also explain what they intend to do to

11

make sure that new and expectant mothers are not exposed to risks that could cause
them harm. The information should be given also to employees' representatives.

If there is a risk, employers should inform employees of the importance of early
detection of pregnancy.

Avoiding the risk

If a significant risk to the health or safety of a new or expectant mother is identified, the
action to be taken to reduce this should be decided upon.

Keeping the risks under review

The employer will review the risk assessments for new or expectant mothers if he is
aware of any change. Although any hazards are likely to remain constant, the possibility
of damage to the unborn child as a result of a hazard will vary at different stages of
pregnancy. Furthermore, there are different risks to consider for workers who have
recently given birth or are breastfeeding.

Employers need to ensure that workers who are breastfeeding are not exposed to risks
that could damage health or safety for as long as they continue to breastfeed. The
Directive concerning the minimum safety and health requirements for the workplace
(89/654/EEC) requires appropriate conditions to be provided for pregnant women and
nursing mothers to rest.

Where workers continue to breastfeed for many months after birth, employers will need
to review the risks regularly. Where they identify risks, there is a need to continue to
follow the three steps to avoid exposure to the risks,
i.e. adjustment of working
hours/conditions, alternative work or exemption from normal duties, for as long as it
threatens the health and safety of a breastfeeding worker or her child. The main concern
is exposure to substances such as lead, organic solvents, pesticides and antimitotics, as
some of the substances are excreted through the milk, and the child is assumed to be
particularly sensitive. The most

exposure. Professional advice from occupational health specialists may be required in
special cases.

RISK ASSESSMENT OF GENERIC HAZARDS AND ASSOCIATED SITUATIONS

Generic hazards and associated situations which are likely to be met by most pregnant women, new/or breastfeeding mothers are listed below:

situations

legislation other
than Directive
92/85/EEC

It may be necessary to adjust working hours
temporarily, as well as other working conditions,
including the timing and frequency of rest breaks, and
to change shift patterns and duration to avoid risks.

With regard to night work, alternative day work should
be organised for pregnant women.

Long working hours, shift work and night work can have a
significant effect on the health of new and expectant
mothers, and on breastfeeding. Not all women are affected in
the same way, and the associated risks vary with the type of
work undertaken, working conditions and the individual
concerned. This applies especially to health care. Generally,
however, both mental and physical fatigue increases during
pregnancy and in the postnatal period due to the various
physiological and other changes taking place.

from increasing tiredness,

Because they suffer
some
pregnant and breastfeeding women may not be able to work
irregular or late shifts or night work, or overtime. Working
time arrangements (including provisions for rest breaks, and
their frequency and timing) may affect the health of the
pregnant woman and her unborn child, her recovery after
childbirth, or her ability to breastfeed, and may increase the
risks of stress and stress related ill health. Because of
changes in blood pressure which may occur during and after
pregnancy and childbirth, normal patterns of breaks from
work may not be adequate for new or expectant mothers.

*

The examples in this column are for guidance only. Other preventive measures exist for all the risks listed. It is up to individual employers to select the measures
most appropriate to their situation, while complying with applicable Community and national legislation.

13

Postural problems
connected with the
activity of new or
expectant mothers

Work at heights

Working alone

Fatigue from standing and other physical work has long been
associated with miscarriage, premature birth and low birth
weight.

It is hazardous working in tightly fitting workspaces or with
workstations which do not adjust sufficiently to take account
of increased abdominal size, particularly during the later
stages of pregnancy. This may lead to strain or sprain
of
injuries. Dexterity,
movement, reach and balance may also be impaired, and an
increased risk of accidents may need to be considered.

co-ordination,

agility,

speed

Ensure that the hours, volume and pacing of work are
not excessive and that, where possible, the employees
themselves have some control over how work is
organised.

Ensure that seating is available where appropriate.

Fatigue can be avoided or
reduced by making it
possible to take longer and more frequent breaks during
the work session.

Adjusting workstations or work procedures may help
remove postural problems and the risk of accidents.

It is hazardous for pregnant workers working at heights, for
example ladders, platforms.

The employer must ensure that pregnant workers are
not exposed to work at heights.

Pregnant women are more exposed to risk than others when
working alone, particularly if they fall or if urgent medical
attention is required.

and

Occupational stress

New and expectant mothers can be particularly affected by
occupational stresses, for various reasons:

-

-

hormonal, physiological and psychological changes
occur and sometimes change rapidly during and after
pregnancy, sometimes affecting susceptibility to stress,
or to anxiety or depression in individuals;

financial, emotional and job insecurity may be affected
by the changes in economic circumstances brought about
by pregnancy, especially if this is reflected in workplace
culture;

Protective measures may include adjustments

the necessary understanding, support and recognition is
there when the woman returns to work, whilst her
privacy is also respected.

Directive
89/391/EEC is
applicable.

-

-

it may be difficult to combine work and private life,
especially with long, unpredictable or unsociable
working hours or where other family responsibilities are
involved;

possible exposure to situations involving violence at the
workplace.

If a woman is exposed to the risk of violence at work
during pregnancy, when she has recently given birth or
while she is breastfeeding this may be harmful. It can lead
to detachment of the placenta, miscarriage, premature
delivery, underweight birth and it may affect the ability to
breastfeed.

This risk particularly affects workers in direct contact with
customers and clients.

Additional work-related stress may occur if a woman’s
anxiety about her pregnancy, or about
its outcome (e.g.
where there is a past history of miscarriage, stillbirth or other
abnormality) is heightened as a result of peer group or other
pressure in the workplace.

Stress is associated in some studies with increased incidence
of miscarriage and pregnancy loss, and also with impaired
ability to breastfeed.

Women who have recently suffered loss through stillbirth,
miscarriage, adoption at birth or neonatal death, will be
especially vulnerable to stress, as will women who have
experienced serious illness or trauma (including Caesarean
section) associated with pregnancy or childbirth. However,
in certain circumstances, returning to work after such events
may help to alleviate stress, assuming a sympathetic and
supportive work environment.

15

Standing activities

Sitting activities

Lack of rest and
other welfare
facilities

Physiological changes during pregnancy (increased blood
and systolic volume, general dilatation of blood vessels and
possible compression of abdominal or pelvic veins) promote
peripheral congestion while standing. Venous compression
may reduce the venous return from the pelvis which leads to
compensatory increases in the maternal heart rate and to
contractions of the uterus. If the compensation is insufficient,
this may lead to dizziness and faintness.

long periods
Continuous standing (and/or walking)
during the working day also contributes to an increased risk
of premature childbirth.

for

Pregnancy-specific changes in the coagulation factors and
mechanical compression of the pelvic veins by the uterus
pose a relatively high risk of thrombosis or embolism for
pregnant women. When sitting still during pregnancy, the
venous filling in the legs increases significantly and may
cause aching and oedema in the legs. The increase in lumbar
lordosis caused by the increase in abdominal circumference
can lead to muscular pain in the lumbar region of the spine,
which may be intensified by remaining in a specific position
for an excessively long period of time.

Rest is important for new and expectant mothers. Tiredness
increases during and after pregnancy and may be
exacerbated by work-related factors. The need for rest is
both physical and mental.

Cigarette smoke is mutagenic and carcinogenic and is a
known risk to pregnancy where the mother smokes. The
effects of passive smoking are less clear but are known to
affect the heart and lungs, and to pose a risk to infant health.
Cigarette smoke is also a respiratory sensitiser, and is known
to be associated with asthma, the onset of which is associated
in some cases with pregnancy.

The need for physical

intervals.

Council Directive
89/654/EEC
(health and safety
requirements for

Expectant mothers must be warned of the dangers of
smoking, including passive smoking. Where there is no
official ban on smoking in communal areas such as rest
rooms and canteens, the employer must take account of
the potential danger to pregnant women of exposure to
cigarette smoke; adopting, if necessary, preventive and
protection measures.

Hazards as a result
of inappropriate
nutrition

Without easy access to toilets (and associated hygiene
facilities) at work, due to distance, work processes or
systems, etc., there may be increased risks to health and
safety, including significant risks of infection and kidney
disease.

Because of pressure on the bladder and other changes
associated with pregnancy, pregnant women often have to go
to the toilet more frequently and more urgently than others.
Breastfeeding women may also need to do so because of
increased fluid intake to promote breast milk production.

Adequate and appropriate nutrition and liquid refreshment
(especially clean drinking water) at regular intervals is
essential to the health of the new or expectant mother and her
child(ren). Appetite and digestion are affected by the timing,
frequency and duration
and other
opportunities for intake of food and drink, and this also
affects the health of the unborn child. This is affected during
and after pregnancy by hormonal and physiological changes,
including those resulting in or affecting morning sickness
(usually in early pregnancy), the position of the unborn child
in the womb, the nutritional needs of the individual mother
and her unborn or breastfeeding child(ren), etc.

of meal breaks

Pregnant women may need more frequent meal breaks and
more frequent meal breaks and more frequent access to
drinking water or other light refreshments, and may also only
be able to tolerate food “little and often” rather than in larger
quantities at ‘normal’ mealtimes. Their eating patterns and
preferences may change, especially in early stages of
pregnancy, not only in response to morning sickness but also
due to discomfort or other problems in the later stages of
pregnancy.

Protective measures include:

- access to a private room in which to breastfeed or

express breast milk;

- use of

secure,

storing
expressed breast milk whilst at work, and facilities
for washing, sterilising and storing receptacles;

clean refrigerators

for

- time off (without loss of pay or benefits, and without

fear of penalty) to express milk or breastfeed.

Hazard due to
unsuitable or absent
facilities

Access to appropriate facilities for expressing and safely
storing breast milk for breastfeeding mothers, or to enable
infants to be breastfed at or near the workplace, may
facilitate breastfeeding by working women, and may
significantly protect the health of both mother and infant.

Evidence shows that breastfeeding can help to protect the
mother against cancer and helps protect
the child from
certain diseases in infancy. Obstacles to breastfeeding in the
workplace may significantly affect the health of both mother
and child.

RISK ASSESSMENT: SPECIFIC HAZARDS (AND WAYS OF AVOIDING RISKS*)

(INCLUDING PHYSICAL, CHEMICAL AND BIOLOGICAL AGENTS AND WORKING CONDITIONS LISTED IN ANNEX 1 AND 2 TO THE DIRECTIVE
92/85/EEC)

Working conditions can have important effects on the health, safety and welfare of new and expectant mothers. Sometimes it will be the
relationship between the different factors involved which determines the type of risk, rather than one factor on its own.

Since pregnancy is a dynamic state involving continuous changes and developments, the same working conditions may raise different health and
safety issues for different women at different stages of pregnancy, and again on returning to work after childbirth or whilst breastfeeding. Some
of these issues are predictable and apply generally (such as those listed below). Others will depend on individual circumstances and personal
medical history.

Shocks, vibration

Regular exposure to shocks, i.e. sudden severe blow to the
body or low frequency vibration, for example driving or
riding in off-road vehicles, or excessive movement, may
increase the risk of a miscarriage. Long-term exposure to
whole body vibration may increase the risk of premature
birth or low birth weight. Breastfeeding workers are at no
greater risk than other workers.

Work shall be organised in such a way that pregnant
workers and those who have recently given birth are

provisions

National
applying Council Directive
86/188/EEC must be respected. The employer must
ensure that workers who are pregnant, who have
recently given birth or who are breastfeeding are not
exposed to noise levels exceeding national exposure
limit values based on Directive 86/188/EEC.

It should be recognised that use of personal protective
equipment by the mother will not protect the unborn
child from the physical hazard.

As soon as a pregnant woman informs the undertaking
of her condition, the protection of the child to be born
must be comparable with that provided for members of
the public. The conditions for the pregnant woman in
the context of her employment are therefore such that
the equivalent dose to the unborn child will be as low
as reasonably achievable and that it will be unlikely
that this dose will exceed 1 mSv during at least the
remainder of the pregnancy.

Average exposure over 5 years for any worker may not
exceed 20 mSv per year (and may not exceed 50 mSv
in any one year).

The employer must inform female workers exposed to
ionising radiation of the need to declare the pregnancy
as soon as possible, having regard to the risks of
exposure for the unborn child and of contamination of
the breastfed child in the event of bodily radioactive
contamination.

Noise

Prolonged exposure to loud noise may lead to increased
blood pressure and tiredness.

Experimental evidence suggests that prolonged exposure of
the unborn child to loud noise during pregnancy may have an
effect on later hearing and that low frequencies have a
greater potential for causing harm.

There are no particular problems for women who have
recently given birth or who are breastfeeding.

Ionising radiation

Exposure to ionising radiation involves risks to the unborn
child; there are therefore particular provisions to limit the
exposure of the expectant mother and the unborn child.

The possibility cannot be excluded that electromagnetic or

and safety measures.

readily faint or be more liable to heat stress. The risk is
likely to be reduced after birth but it is not certain how
quickly an improvement comes about. Exposure to heat may
lead to adverse pregnancy outcomes.

Breastfeeding may be impaired by heat dehydration.

Working in extreme cold may be a hazard for pregnant
women and their unborn child. Warm clothing should be
provided.

The risks are increased particularly in the event of sudden
changes in temperature.

Compressed air: People working under high pressure are at
risk of developing the bends. This is due to free bubbles of
gas in the circulation.

It is not clear whether pregnant women are more at risk of
the bends but the unborn child could potentially be seriously
harmed by such gas bubbles.

For those who have recently given birth there is a small
increase in the risk of the bends.

There is no physiological reason why a breastfeeding mother
should not work under high pressure (although there would
be obvious practical difficulties).

Diving: Pregnant workers are advised not to dive at all
during pregnancy due to the possible effects of exposure to a
hyperbaric environment on the unborn child.

There is no evidence to suggest that breastfeeding and diving
are incompatible.

Pregnant workers should not be exposed to prolonged
excessive heat or cold at work .

Pregnant workers should not work in a high-pressure
atmosphere.

Framework
Directive

The employer must ensure that workers who are
pregnant are aware that pregnancy can constitute a
medical reason not to dive; and such workers should
inform the employer if there is any medical reason why
they should not dive, so that the employer can take
appropriate action.

How to deal with the risk

The substances are listed in Annex 1 of Directive
67/548/EEC and are labelled with the risk phrases:

R40: possible risk of irreversible effects;

R45: may cause cancer;

R46: may cause heritable genetic damage;

R49:may cause cancer by inhalation;

R61: may cause harm to the unborn child;

R63: possible risk of harm to the unborn child;

R64: may cause harm to breastfed babies.

The actual risk to health of these substances can only be
determined following a risk assessment of a particular
substance at
the place of work - i.e. although the
substances listed may have the potential to endanger
health or safety, there may be no risk in practice, for
example if exposure is below a level which might cause
harm.

Examples of preventive measures*

For work with hazardous substances, which include
chemicals which may cause heritable genetic damage,
employers are required to assess the health risks to
workers
and where

Mercury and
mercury derivatives

Organic mercury compounds could have adverse effects on
the unborn child. Animal studies and human observations
have demonstrated that exposure to these forms of mercury
during pregnancy can slow the growth of the unborn baby,
disrupt the nervous system, and cause the mother to be
poisoned.

Organic mercury is transferred from blood to milk. That may
pose a risk to offspring, if a woman is highly exposed before
and during pregnancy.

it is not appropriate to prevent the risk, control of
exposure may be by a combination of

technical measures

Chronic exposure of female workers should be avoided.
Even occasional exposure to CO could potentially be
harmful.

Pregnant workers should be informed about the dangers
of exposure to carbon monoxide during smoking.

Carbon monoxide

Carbon monoxide is produced by using petrol, diesel and
liquefied petroleum gas (LPG) as a source of power in
engines and in domestic appliances. Risks arise when
engines or appliances are operated in enclosed areas.

Pregnant women may have heightened susceptibility to the
effects of exposure to carbon monoxide.

Carbon monoxide readily crosses the placenta and can result
in the unborn child being starved of oxygen. Data on the
effects of exposure to carbon monoxide on pregnant women
are limited, but there is evidence of adverse effects on the
unborn child. Both the level and duration of maternal
exposure are important factors in the effect on the unborn
child.

There is no indication that breastfed babies suffer adverse
effects from their mother's exposure to carbon monoxide, nor
that the mother is significantly more sensitive to carbon
monoxide after giving birth.

Given the extreme risk of exposure to high levels of CO, risk
assessment and prevention of high exposure are identical for
all workers.

Risk assessment may be complicated by active or passive
smoking and/or ambient air pollution. If those sources lead
to a higher COHb than occupational exposure would, the
level of risk is determined by those outside sources, as the
effect on COHb is not cumulative.

However, careful documentation of such “outside” sources
may be required to avoid liability and litigation

28

Women with reproductive capacity must be subject to a
lower blood-lead suspension level than other workers,
to protect any developing unborn child.

Once their pregnancy is confirmed, women who are
subject to medical surveillance under the lead Directive
will normally be suspended from work which exposes
them significantly to lead.

European limit values are in the process of being
reviewed.

Because the elimination of lead from the body is a very
slow process, fertile women should be informed of this.
The employer must ensure that exposure to lead is
reduced and that women have the option of placement
elsewhere until this has been done.

Council Directive
82/605/EEC
(exposure to
metallic lead at
work) which will
be repealed upon
transposal by the
Member States of
Directive 98/24/EC
(by 5 May 2001).

In view of this, banning pregnant and breastfeeding
women from all lead-containing areas may be the only
acceptable option. This is particularly advisable if there
is exposure to organic lead compounds.

Lead and lead
derivatives - in so
far as these agents
are capable of being
absorbed by the
human organism

Historically, exposure of pregnant women to lead is
associated with abortions and miscarriages, but there is no
indication that
this is still relevant at current accepted
standards for exposure. There are strong indications that
exposure to lead, both intra-uterine and post-partum, leads to
developmental problems, especially of the nervous system
and the blood-forming organs. Women, new-born and young
children are more sensitive to lead than male adults.

Lead is transferred from blood to milk. This may pose a risk
to offspring if a woman is highly exposed before and during
pregnancy.

Indications of safe levels
Exposure to lead cannot safely be measured in terms of
airborne exposure levels, because of the different uptake
routes. Biological monitoring of blood lead levels (PbB) and
tests for zinc proto
biological effects monitoring (e.g.
porphyrin and levels of amino laevulinic acid in blood or
urine) are the best exposure indicators.

Risk assessment
A risk of exposure of pregnant and breastfeeding women to
lead is specifically prohibited under Article 6 of
the
Directive if the exposure might jeopardise safety or health.
The risk assessment
should be based upon both the
individual’s and the work group’s historical record of blood
lead levels or similar parameters, not on ambient air
monitoring. Where these are within the range of unexposed

Manual handling of
loads

What is the risk?

How to deal with the risk

Manual handling of heavy loads is considered to pose a risk
to pregnancy, such as risk of foetal injury and premature
birth. The risk depends on strain, i.e. the weight of the load,
how you lift and how often it occurs during work time.

As the pregnancy progresses, a pregnant worker is at greater
risk from manual handling injury. This is due to hormonal
relaxation of the ligaments and the postural problems of
advancing pregnancy.

There can also be risks for those who have recently given
birth, for example after a Caesarean section there is likely to
be a temporary limitation on lifting and handling capability.

Breastfeeding mothers may experience discomfort due to
increased breast size and sensitivity.

Examples of preventive measures*

The changes an employer should make will depend on
the risks
and the
identified in the assessment
circumstances of the business. For example, it may be
possible to alter the nature of the task so that risks from
manual handling are reduced for all workers, including
new or expectant mothers. Or it may be necessary to
address the specific needs of the worker and reduce the
amount of physical work, or provide aids for her in
future to reduce the risks she faces.

Where there is a risk particularly of back injury to
workers, Directive 90/269/EEC requires employers to:

-

-

-

avoid the need for hazardous manual handling;

assess the risks from those operations that cannot
be avoided; and

Movements and

The nature and extent of any risks of injury or ill health
resulting from movements or posture during and after

pregnancy progresses, especially if
awkward movements or long periods of standing or sitting in
one position where the body is exposed to risks of prolonged
static load or impaired circulation. These may contribute to
the development of varicose veins and haemorrhoids as well
as backache.

32

Backache in pregnancy may be associated with prolonged
work and poor working posture, as well as excessive
movement. A pregnant woman may need more workspace,
or may need to adapt the way she works (or the way she
interacts with the work of others or with her work
equipment) as pregnancy changes both her size and the ways
in which she can move, stand or sit still for a long time in
comfort and safety.

There may also be additional risks if a woman is returning to
work after a childbirth with medical complications such as a
Caesarean birth or deep vein thrombosis.

Travelling in the course of work, and to and from the
workplace, can be problematic for pregnant women,
involving risks including fatigue, vibration, stress, static
posture, discomfort and accidents. These risks can have a
significant effect on the health of new and expectant
mothers.

the physical agents described in this guidance are a regular

Work with display
screen equipment
(VDUs)

Although not specifically listed in Directive 92/85/EEC, the Advisory Committee and the Commission are aware that anxiety about radiation
emissions from display screen equipment and possible effects on pregnant women has been widespread. However, there is substantial evidence
that these concerns are unfounded. The advice below summarises scientific understanding.

In the light of the scientific evidence, pregnant women
do not need to stop working with VDUs. However, to
avoid problems caused by stress and anxiety, women
who are pregnant and are worried about working with
VDUs should be given the opportunity to discuss their
concerns with someone adequately informed of current
authoritative scientific information and advice.

Council Directive
90/270/EEC on
display screen
equipment

The levels of electromagnetic radiation which are likely to be
generated by display screen equipment are well below those
set out in international recommendations for limiting risk to
and the
human health created by such emissions,
Radiological Protection Board does not consider such levels
to pose a significant risk to health. No special protective
measures are therefore needed to protect the health of people
from this radiation.

There has been considerable public concern about reports of
higher levels of miscarriage and birth defects among some
groups of visual display unit (VDU) workers, in particular
due to electromagnetic radiation. Many scientific studies
have been carried out, but taken as a whole their results do
not show any link between miscarriages or birth defects and
working with VDUs. Research and reviews of the scientific
evidence will continue to be undertaken.

There may also be ergonomic risks from work with VDUs -
see above.

and personal
protective
equipment
(including clothing)

Work equipment and personal protective equipment is not
generally designed for use by pregnant women. Pregnancy
(and breastfeeding) involves physiological changes which
may make some existing work and protective equipment not
only uncomfortable but also unsafe for use in some cases -
for example, where equipment does not fit properly or
comfortably, or where the operational mobility, dexterity or
co-ordination of
temporarily
the woman concerned is
impeded by her pregnancy or recent childbirth.

The employer must carry out a risk assessment which
takes account of changes in risks as pregnancy
progresses.

the risk should be avoided by
Wherever possible,
adaptations or substitution e.g. of suitable alternative
equipment to allow the work to be conducted safely and
without risk to health. Where this is not possible, the
provisions of Directive 92/85/EC (Article 5) come into
effect. Unsafe working must not be allowed.

Directive
89/655/EEC (safety
and health
requirements for
the use of work
equipment by
workers at work)

Directive
89/656/EEC (safety
and health
requirements for
the use by workers
of personal
protective
equipment at the
workplace)
