4 Mechanical hazards — Safety philosophy
This clause addresses the most widely known mechanical hazards and is intended to provide guidance
when drafting standards for child care articles.
Anthropometric data and information on the abilities of children related to risks are given in
CEN/TS 13387-1:2024, Annex A. When using these data for setting requirements, adequate safety
margins should be considered. These data refer to static and not dynamic anthropometric data, therefore
care should be taken if using these data for anything other than static situations when drafting standards.
When drafting standards, conditions of use should be considered, bearing in mind the behaviour of
children. Also, it is to be considered whether the child is attended or unattended when using the product
and also the child’s access to hazardous features.
kSIST-TS FprCEN/TS 13387-3:2025
FprCEN/TS 13387-3:2025 (E)
For each mechanical hazard a rationale is given, explaining the potential hazard to the child.
Requirements, test equipment and test methods are also given. Where appropriate, these can be used
when drafting standards.
New technologies, e.g. fingerprint or face recognition or others, could be used for opening and closing a
mechanical device or for operating a product.
When developing technical standards for child care articles, if these new technologies are identified as a
possible option for use within a product category, specific requirements and test methods to assess their
safety should be defined.
5 Accessibility of mechanical hazards
5.1 General
Within the mechanical section no reference is made to specific areas of access, known as access zones. It
would be wrong for this guidance document to specify exact areas of access as these should be
determined in relation to the hazards and risks of individual products and risks when drafting the
standard. As a general guidance to the types of contact associated with mechanical hazards, the following
examples are given:
— the hazardous part is in reach of the child from the intended position of use in particular by head,
mouth, hands or feet and there is a high probability for frequent, intensive and/or prolonged contact.
Requirements need to address this primary contact;
— the hazardous part can be reached by the child or any other child beyond the intended position of
use. The product is considered to remain in its intended position(s). Access to hazardous parts is
gained by passing/moving around the product or when proceeding to the intended position. The risk
of harm deriving from frequent, intensive and/or pro-longed contact can be less probable;
— the hazardous part exists, but cannot be reached by any child.
Irrespective of the access category, the reasonably foreseeable conditions of use should always be
considered when designing children’s products and/or writing product standards.
5.2 Accessibility areas
Information for determination of accessibility areas in connection with age group is given in Table 1 and
Figure 1. These reach envelopes are based on a computer simulation; therefore, the dimensions should
be treated with care. If in the future experiments with children are undertaken, these figures in the table
can be determined more accurately.

5.3 Product information
In order to ensure mechanical safety, the information for the carer should include appropriate
instructions and warnings. For example:
— the need for restraint system and its adjustment;
— the opening and closing of products;
— the operation of safety locks for foldable parts;
— the method of attachment to fixed structures or to other products.
Instructions should also inform the carer of the need to inspect the product regularly and also to use only
replacement parts that are approved by the manufacturer/supplier.

6 Entrapment hazards
6.1 Introduction
To avoid entrapment of head, neck, fingers, feet, and hands, safety distances are recommended in relation
to the anthropometric data (see CEN/TS 13387-1:2024, Annex A) of the growing child. It is important to
take into account the intended age and/or development level of the child. As a priority, those parts of a
product which are accessible when a child is using the product as foreseeable should be considered. It
can also be appropriate for gaps and openings beyond these accessible areas to be addressed. Gaps and
openings which are inaccessible need not to be considered. However, V-shaped openings or V-shaped
arrangements of structural members should be avoided.
Important entrapment hazards are:
— entrapment of the neck in situations where the child is incapable of raising its body weight to relieve
the pressure (e.g.: crawling child on the outside of play pen, V shapes, etc.);
— entrapment of the neck in situations where the child slips through a gap feet first (e.g.: child slipping
between bars/slats);
— entrapment of fingers, which can cause loss of blood supply to the tips.
If it is possible to position a child care article next to other furniture or a wall and create an entrapment
hazard between them, an instruction should be included to warn carers of this possible entrapment
hazard. When considering entrapment hazards dynamic situations should be considered as well as static
hazards. The dynamic situation will increase the force being applied to a trapped torso or finger through
the weight, movement or momentum of the child which will increase the risk of injury.
To assist with this an entrapment matrix has been included, see Figure 2, which was based on work done
in ISO/IEC Guide 50. This entrapment matrix does not impart any hierarchy in the severity of the hazards
shown and the specific hazard clause should be referred to.

6.2 Entrapment of head and neck
6.2.1 Rationale
Head and neck hazards occur when the child is in a position where its body weight is supported by its
neck and the child is incapable of lifting its body weight to relieve pressure on its neck. When this occurs,
it will cause airways to close and restrict the blood flow, leading to brain damage.
The risk of head and neck entrapment increases as the child’s mobility and ability increases, enabling the
child to access a wider range of hazards and products. The hazard is directly related to the size of the
child’s head and hip.
The hazard can be avoided by limiting the size and shape of completely bound, partially bound and ‘V’
shaped openings (see definitions in 6.2.2).
6.2.2 Terms and definitions related to entrapment hazards
6.2.2.1 completely bound opening
opening that is continuously surrounded on all sides by the material of the product, see Figure 3
kSIST-TS FprCEN/TS 13387-3:2025
FprCEN/TS 13387-3:2025 (E)

6.2.2.2 partially bound opening
opening that is partially surrounded by the material of the product, see Figure 4

Figure 4 — Examples of partially bound openings
6.2.2.3 V shaped opening
opening where there is a slot that narrows towards the bottom, see Figure 5

Figure 5 — Examples of V shaped openings
6.2.2.4 irregular shaped opening
opening that does not have a symmetrical shape, see Figure 6
kSIST-TS FprCEN/TS 13387-3:2025
FprCEN/TS 13387-3:2025 (E)
Figure 6 — Example of an irregular shaped opening
6.3 Requirements
When tested in accordance with 6.5.1 or 6.5.2, if openings allow passage of the small probe, the large
probe should pass through. The opening that allows the large probe to pass completely through should
comply with the requirement for partially bound, V and irregular shaped openings when tested in
accordance with 6.5.3.
Partially bound, V and irregular shaped openings should be constructed so that:
a) portion B of the template does not enter the opening when tested in accordance with 6.5.3,
see Figure 11 and Figure 12; or
b) the apex of portion A of the template contacts the base of the opening when tested in accordance
with 6.5.3, see Figure 13.
6.4 Test equipment
6.4.1 Probe philosophy
To cover all aspects of head and neck entrapment four types of probes are required, the hip probe, the
small head probe, the large head probe and the template for partially bound and V-shaped openings. The
size of individual probes is determined to meet the age range of the child, see the figures and tables for
the various probes.
6.4.2 Hip probe
The hip probe, Figure 7, represents the hip of the smallest child in each age range. The probe size
corresponds to the size of the child as follows:
— dimension ‘A’ represents the hip breadth;
— dimension ‘B’ represents hip depth;
— dimension ‘C’ represents the radius C after calculation based on hip circumference.
The dimensions of the hip probe are based on the anthropometric data, see Table 2.

6.4.6 Selection and use of probes
6.4.6.1 Probe size
The correct size of probe should be selected from the ranges shown in Table 2 to Table 4, to suit the age
range of the child most at risk when considering the hazard.
By checking the opening with the large head probe, Figure 9 it is possible to ascertain whether the
opening is small enough to be a hazard to a child. If the opening is found to be hazardous the opening
should be tested to determine if it is large enough for the child to enter either feet first or head first by
using one of the appropriate small probes, Figure 7 or Figure 8, as indicated below.
6.4.6.2 Feet first openings
The hip probe, Figure 7 should be used to check if the opening is small enough to prevent passage of a
child’s hip. If it does not pass through the opening the risk of entrapment is reduced.
6.4.6.3 Head first openings
The small head probe, Figure 8, should be used to check if the opening is small enough to prevent passage
of a child’s head. If the small head probe does not pass through the opening the risk of head first
entrapment is reduced.
If the small head probe passes completely
