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).
---------------------- Page: 7 ----------------------
SIST EN 115-2:2021
EN 115-2:2021 (E)
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

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.

“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.
---------------------- Page: 12 ----------------------
SIST EN 115-2:2021
EN 115-2:2021 (E)
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

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).
---------------------- Page: 7 ----------------------
oSIST prEN 115-2:2020
prEN 115-2:2020 (E)
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 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.

"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.
