Introduction
Background of this document
More than 136 500 escalators and moving walks are in use today in the European Union (EU) and
European free Trade Association (EFTA) and almost 50 % were installed more than 20 years ago.
However, this document compares the safety level of escalators and moving walks installed after 1970
with those within EN 115-1:2017. This recognizes that the first attempt to have a common standard for
escalators and moving walks was the CIRA Recommendation 28 [1]. Escalators and moving walks were
installed to the safety level appropriate at that time. This level is less than today’s state of the art for
safety.
New technologies and social expectations have led to today's state of the art for safety. This has led to the
situation today of different levels of safety across Europe causing accidents. However, users and
authorized persons expect a common acceptable level of safety.
Furthermore, the life cycle of escalators and moving walks is longer than most other transportation
systems and building equipment, which therefore means that the design, performance and safety can fall
behind modern technologies. If all existing escalators and moving walks are not upgraded to today's state
of the art of safety the number of injuries will increase (especially in areas which can be accessed by the
general public, recognizing the change of behaviour and changing attitudes towards safety in general). If
escalators or moving walks were installed before 1970 on the base of manufacturer's and national
standards or were installed after 1970 but not in accordance with CIRA Recommendation 28, then they
should be the subject of a separate risk assessment in addition to the recommendations of this document
to determine whether a safety upgrade or a full replacement is appropriate.
Approach of this document
This document:
— categorizes various hazards and hazardous situations, each of which has been analysed by a risk
assessment (see in particular Annex A);
— is intended to provide corrective actions to progressively and selectively improve, step by step, the
safety of all existing escalators and moving walks towards today’s state of the art for safety (see
Clause 5);
— enables each escalator and moving walk to be audited and safety measures to be identified and
implemented in a step by step and selective fashion according to the frequency and severity of any
single risk (see Table B.2);
— lists the high, medium and low risks and corrective actions which can be applied in separate steps in
order to mitigate the risks (see Table B.2).

Use of this document
This document can be used as a guideline for:
a) national authorities to determine its own programme of implementation in a step by step process via
1
a filtering process (see Annex A) in a reasonable and practicable way based on the level of risk (e.g.
high, medium, low) and social and economic considerations;
b) owners to follow their responsibilities according to existing regulations (e.g. use of Work Equipment
Directive);
c) maintenance companies and/or inspection bodies to inform the owners on the safety level of their
installations;
d) owners to upgrade the existing escalator or moving walk on a voluntary basis in accordance with c)
if no regulations exist.
In making an audit of an existing escalator or moving walk installation Annex B can be used to identify
the hazards and corrective actions in this document. However, where a hazardous situation is identified
which is not covered in this document a separate risk assessment should be made. This risk assessment
should be based on ISO 14798 [4].
The need for replacement was based on the revision of EN 115-1, which was published in 2017.
1
“Reasonable and practicable” is defined as follows: “In deciding what is reasonably practicable the seriousness
of a risk to injury should be weighted against the difficulty and cost of removing or reducing that risk. Where
the difficulty and costs are high, and a careful assessment of the risk shows it to be comparatively unimportant,
action may not need to be taken. On the other hand where the risk is high, action should be taken at whatever
cost.”.

5 Safety requirements and/or protective measures
5.1 General
The following requirements and/or protective measures shall not be considered as the only possible
solution. Alternatives are permitted, provided they lead to an equivalent safety level.
A risk assessment shall be made on a case by case basis to identify hazards or hazardous situations not
covered in this document.
Where the requirements of this document cannot be met technically and a residual risk remains, or
cannot be avoided, the level of risk shall be reduced as far as it is practicable. When residual risk remains
the use of appropriate procedures such as signs, instructions and training should be considered.
Harmful materials such as asbestos in brake linings, contactor shields, cladding including machinery
spaces and separate machine rooms or control cabinet locations, etc. shall be replaced by materials which
ensure the same performance level.
These should be considered in relation to national requirements.
For specific requirements such as accessibility, the conditions in the building shall be assessed to
determine what is practical to be applied for escalators and moving walks.
If an escalator or moving walk has been upgraded by one of the measures described in this document, the
consequences to other parts of the escalator or moving walk shall be considered with special regard to
EN 115-1:2017.

5.2 Supporting structure (truss) and enclosure
5.2.1 General
All mechanically moving parts of the escalator or moving walk shall be completely enclosed within panels
or walls. Exempt from this are the accessible steps, the accessible pallets, the accessible belt and that part
of the handrail available for the user. Ventilation apertures in compliance with EN ISO 13857:2019,
Table 5 are permitted.
Exterior panels which are designed to be opened (e.g. for cleaning purposes), inspection covers and floor
plates shall be provided with an electric safety device according to EN 115-1:2017, Table 8 M). For
inspection covers and floor plates it shall only be possible to open them by a key or a tool suited for that
purpose.
If rooms behind inspection covers and floor plates can be entered, it shall be possible to open them from
the inside without a key or a tool even when locked.
It is permissible to omit an enclosure of the mechanically moving parts if other measures (such as rooms
with locked doors accessible to authorized personnel only) make a hazard to the public impossible.
5.2.2 Fire hazard
5.2.2.1 Accumulation of combustible material inside the truss due to the daily environmental
pollution can generate a fire hazard. Therefore, the inner part of the escalator/moving walk shall be
cleaned regularly.
5.2.2.2 Depending on the maintenance conditions, e.g. access, fire protection systems shall be
installed.
5.3 Steps, pallets and belt
5.3.1 Tread surfaces for escalators and moving walks shall provide a secure foothold taking into
consideration the operational and environmental conditions.
5.3.2 Demarcation (e.g. groove in the step tread) shall be provided to highlight at the landings the rear
edge of the steps.
5.3.3 The lateral displacement of the steps or pallets out of their guiding system shall not exceed 4 mm
at either side and 7 mm for the sum of clearances measured at both sides.
The vertical displacement shall not exceed 4 mm for steps and pallets and 6 mm for belts.
5.3.4 Clearances for steps with cleated risers and pallets with meshing front and rear edges shall not
exceed 6 mm between two consecutive steps or pallets in any usable position measured at th

Introduction
Background of this standard
More than 136 500 escalators and moving walks are in use today in the European Union (EU) and
European free Trade Association (EFTA) and almost 50 % were installed more than 20 years ago.
However, this standard compares the safety level of escalators and moving walks installed after 1970
with those within EN 115-1:2017. This recognizes that the first attempt to have a common standard for
escalators and moving walks was the CIRA Recommendation 28 [1]. Escalators and moving walks were
installed to the safety level appropriate at that time. This level is less than today’s state of the art for
safety.
New technologies and social expectations have led to today's state of the art for safety. This has led to the
situation today of different levels of safety across Europe causing accidents. However, users and
authorized persons expect a common acceptable level of safety.
Furthermore the life cycle of escalators and moving walks is longer than most other transportation
systems and building equipment, which therefore means that the design, performance and safety can fall
behind modern technologies. If all existing escalators and moving walks are not upgraded to today's state
of the art of safety the number of injuries will increase (especially in areas which can be accessed by the
general public, recognizing the change of behaviour and changing attitudes towards safety in general). If
escalators or moving walks were installed before 1970 on the base of manufacturer's and national
standards or were installed after 1970 but not in accordance with CIRA Recommendation 28, then they
should be the subject of a separate risk assessment in addition to the recommendations of this standard
to determine whether a safety upgrade or a full replacement is appropriate.
Approach of this standard
This standard:
— categorizes various hazards and hazardous situations, each of which has been analysed by a risk
assessment (see in particular Annex A);
— is intended to provide corrective actions to progressively and selectively improve, step by step, the
safety of all existing escalators and moving walks towards today’s state of the art for safety (see
Clause 5);
— enables each escalator and moving walk to be audited and safety measures to be identified and
implemented in a step by step and selective fashion according to the frequency and severity of any
single risk (see Table B.2);
— lists the high, medium and low risks and corrective actions which can be applied in separate steps in
order to mitigate the risks (see Table B.2).

Use of this standard
This standard can be used as a guideline for:
a) national authorities to determine its own programme of implementation in a step by step process via
1)
a filtering process (see Annex A) in a reasonable and practicable way based on the level of risk (e.g.
high, medium, low) and social and economic considerations;
b) owners to follow their responsibilities according to existing regulations (e.g. use of Work Equipment
Directive);
c) maintenance companies and/or inspection bodies to inform the owners on the safety level of their
installations;
d) owners to upgrade the existing escalator or moving walk on a voluntary basis in accordance with c)
if no regulations exist.
In making an audit of an existing escalator or moving walk installation Annex B can be used to identify
the hazards and corrective actions in this standard. However, where a hazardous situation is identified
which is not covered in this standard a separate risk assessment should be made. This risk assessment
should be based on ISO 14798 [2].
The need for replacement was based on the revision of EN 115-1, which was published in 2017.
1)
"Reasonable and practicable” is defined as follows: “In deciding what is reasonably practicable the seriousness
of a risk to injury should be weighted against the difficulty and cost of removing or reducing that risk. Where the
difficulty and costs are high, and a careful assessment of the risk shows it to be comparatively unimportant, action
may not need to be taken. On the other hand where the risk is high, action should be taken at whatever cost.”.

1 Scope
This document gives rules for improving the safety of existing escalators and moving walks with the aim
of reaching an equivalent level of safety to that of a newly installed escalator and moving walk by the
application of today’s state of the art for safety.
NOTE Due to situations such as the existing machine or building designs, it may not be possible in all cases to
reach today’s state of the art for safety. Nevertheless the objective is to improve the level of safety wherever
possible.
This document includes the improvement of safety of existing escalators and moving walks for:
a) users;
b) maintenance and inspection personnel;
c) persons outside the escalator or moving walk (but in its immediate vicinity);
d) authorized persons.
This document is not applicable to:
a) safety during transport, installation, repairs and dismantling of escalators and moving walks;
b) spiral escalators;
c) accelerating moving walks.
However, this document can usefully be taken as a reference basis.

5 Safety requirements and/or protective measures
5.1 General
The following requirements and/or protective measures shall not be considered as the only possible
solution. Alternatives are permitted, provided they lead to an equivalent safety level.
A risk assessment shall be made on a case by case basis to identify hazards or hazardous situations not
covered in this document.
Where the requirements of this document cannot be met technically and a residual risk remains, or
cannot be avoided, the level of risk shall be reduced as far as it is practicable. When residual risk remains
the use of appropriate procedures such as signs, instructions and training should be considered.
Harmful materials such as asbestos in brake linings, contactor shields, cladding including machinery
spaces and separate machine rooms or control cabinet locations, etc. shall be replaced by materials which
ensure the same performance level.
These should be considered in relation to national requirements.

---------------------- Page: 12 ----------------------
oSIST prEN 115-2:2020
prEN 115-2:2020 (E)
For specific requirements such as accessibility, the conditions in the building shall be assessed to
determine what is practical to be applied for escalators and moving walks.
If an escalator or moving walk has been upgraded by one of the measures described in this standard, the
consequences to other parts of the escalator or moving walk shall be considered with special regard to
EN 115-1:2017.
5.2 Supporting structure (truss) and enclosure
5.2.1 General
All mechanically moving parts of the escalator or moving walk shall be completely enclosed within panels
or walls. Exempt from this are the accessible steps, the accessible pallets, the accessible belt and that part
of the handrail available for the user. Ventilation apertures in compliance with EN ISO 13857:2008,
Table 5 are permitted.
Exterior panels which are designed to be opened (e.g. for cleaning purposes), inspection covers and floor
plates shall be provided with an electric safety device according to EN 115-1:2017, Table 8 M). For
inspection covers and floor plates it shall only be possible to open them by a key or a tool suited for that
purpose.
If rooms behind inspection covers and floor plates can be entered, it shall be possible to open them from
the inside without a key or a tool even when locked.
It is permissible to omit an enclosure of the mechanically moving parts if other measures (such as rooms
with locked doors accessible to authorized personnel only) make a hazard to the public impossible.
5.2.2 Fire hazard
5.2.2.1 Accumulation of combustible material inside the truss due to the daily environmental
pollution can generate a fire hazard. Therefore, the inner part of the escalator/moving walk shall be
cleaned regularly.
5.2.2.2 Depending on the maintenance conditions, e.g. access, fire protection systems shall be
installed.
5.3 Steps, pallets and belt
5.3.1 Tread surfaces for escalators and moving walks shall provide a secure foothold taking into
consideration the operational and environmental conditions.
5.3.2 Demarcation (e.g. groove in the step tread) shall be provided to highlight at the landings the rear
edge of the steps.
5.3.3 The lateral displacement of the steps or pallets out of their guiding system shall not exceed 4 mm
at either side and 7 mm for the sum of clearances measured at both sides.
The vertical displacement shall not exceed 4 mm for steps and pallets and 6 mm for belts.
5.3.4 Clearances for steps with cleated risers and pallets with meshing front and rear edges shall not
exceed 6 mm between two consecutive steps or pallets in any usable position measured at the tread
surface.
Clearances for steps with plain risers and pallets without meshing shall not exceed 5 mm between two
consecutive steps or pallets in any usable position measured at the tread surface.
In the area of the transition curves of moving walks with meshed front edges and rear edges of the pallets,
this clearance is permitted to be increased to 8 mm.
