SIST EN 115-2:2010
EN 115-2:2010 (E) 5 Introduction Background of this standard More than 75 000 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 115-1:2008. This recognises 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 authorised 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
categorises 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 a filtering process (see Annex A) in a reasonable and practicable1) way based on the level of risk (e.g. high, medium, low) and social and economic considerations;
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.”. SIST EN 115-2:2010
EN 115-2:2010 (E) 6 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].

EN 115-2:2010 (E) 11 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 standard. Where the requirements of this standard 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. NOTE 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 standard, the consequences to other parts of the escalator or moving walk shall be considered with special regard to
EN 115-1:2008+A1:2010. 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 115-1:2008+A1:2010, Table 6 n). 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 authorised 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. SIST EN 115-2:2010
EN 115-2:2010 (E) 12 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. 5.3.5 A missing step/pallet shall be detected and the escalator/moving walk stopped before the gap (resulting from the missing step/pallet) emerges from the comb. This shall be ensured by a device according to
EN 115-1:2008+A1:2010, Table 6 k), provided at each driving and return station. 5.3.6 The step/pallet chains and the belt shall be tensioned continuously. The escalator/moving walk shall be stopped automatically before the tensioning device moves excessively (see EN 115-1:2008+A1:2010, 5.4.3.3 and Table 6 e) and f)). Springs working in tension are not permitted for the tensioning device. When weights are used for tensioning they shall be safely retained should their suspension break. 5.4 Drive units 5.4.1 Driving machine Stopping the escalator or moving walk by means of the electric safety devices shall be effected as follows: The supply shall be interrupted by two independent contactors, the contacts of which shall be in series in the supply circuit. If, when the escalator or moving walk is stopped, one of the main contacts of one of the contactors has not opened, starting shall be impossible. If a hand winding device is provided it shall be easily accessible and safe to operate. If the hand winding device is removable an electric safety device shall be actuated when or before the hand winding device is put on the machine. Crank handles or perforate hand wheels are not permitted. 5.4.2 Braking system 5.4.2.1 If the design does not prevent excessive speed, escalators and moving walks shall be equipped in such a way that they stop automatically before the speed exceeds a value of 1,2 times the nominal speed. Where speed control devices are used for this purpose they shall have switched off the escalator or moving walk before the speed exceeds a value of 1,2 times the nominal speed and shall be provided with an electrical safety device in accordance with EN 115-1:2008+A1:2010, Table 6 c). 5.4.2.2 Escalators and inclined (α ≥ 6°) moving walks shall be equipped with an electrical safety device in accordance with

Introduction
Background of this standard
More than 75 000 escalators and moving walks are in use today in EU and 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 from EN 115-1:2008. This recognises 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 authorised 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
categorises 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
eliminate the risks (see Table B.2).
Other designs to previous national regulations or standards, providing they have an equivalent safety level, may be
acceptable.
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 a filtering
1)
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);
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.”

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/TS 14798 [2].

1 Scope
1.1 This European Standard 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.
1.2 This standard 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 their immediate vicinity);
d) authorised persons.
1.3 This standard 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 standard 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 for safety items not covered in this standard.

---------------------- Page: 11 ----------------------
oSIST prEN 115-2:2009
prEN 115-2:2009 (E)
Where the requirements of this standard 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.
NOTE These should be considered in relation to national requirements.
For specific requirements such as accessibility, the conditions in the building shall be checked to see 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 115-1:2008.
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 Table 5 of EN ISO 13857:2008 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 115-1:2008, Table 6 n). 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 moved parts if other measures (such as rooms with
locked doors accessible to authorised 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. Written Instructions
and checks shall be available.
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 surrounding environment.
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.

---------------------- Page: 12 ----------------------
oSIST prEN 115-2:2009
prEN 115-2:2009 (E)
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.
5.3.5 A missing step/pallet shall be detected and the escalator/moving walk stopped before the gap (resulting
from the missing step/pallet) emerges from the comb. This shall be ensured by a device according to
EN 115-1:2008, Table 6 k), provided at each driving and return station.
5.3.6 The step/pallet chains and the belt shall be tensioned continuously. The escalator/moving walk shall be
stopped automatically before the tensioning device moves in excess (see EN 115-1:2008, Table 6 e) and f)).
Springs working in tension are not permitted for the tensioning device. When weights are used for tensioning they
shall be safely retained should their suspension break.
5.4 Drive units
5.4.1 Driving machine
Stopping the escalator or moving walk by means of the electric safety devices shall be effected as follows:
The supply shall be interrupted by two independent contactors, the contacts of which shall be in series in the
supply circuit. If, when the escalator or moving walk is stopped, one of the main contacts of one of the contactors
has not opened. Starting shall be impossible.
If a hand winding device is provided it shall be easily accessible and safe to operate. If the hand winding device is
removable an electric safety device shall be actuated when or before the hand winding device is put on the
machine. Crank handles or perforate hand wheels are not permitted.
5.4.2 Braking system
5.4.2.1 If the design does not prevent excessive speed, escalators and
