Foreword
This document (prEN 115:2005) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators
and moving walks”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 115:1995.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA,, which is an integral part of this document.
Considering that EN 115:1995 had given rise to requests for interpretation and this standard did not fully
comply with EN 414 (today CEN Guide 414 "Safety of machinery - Rules for the drafting and presentation of
safety standards"), CEN/TC 10 asked its working group 2 to revise EN 115:1995: This task was completed by
CEN/TC 10/WG 2 in 2005 after 19 working meetings by
taking into account the interpretations;
taking over the agreed upon points from the work carried out by ISO/TC 178/WG 5;
adapting the requirements to the state of the art using the risk assessment methodology as given in
ISO/TS 14798:2000;
improving the references to other standards according to the progress in that field;
covering the requirements of CEN Guide 414 by creating a new structure which addresses the safety
rules for the machine and provides requirements in the normative annexes and information in the
informative annexes;
increasing the measures against foreseeable misuse;
reviewing the safety requirements for escalators and moving walks.
The date of withdrawl (DOW) of EN 115:1995 and its amendments EN 115/A1:1998 and EN 115/A2:2004
shall be 2 years after the date of availability (DAV) of the revised standard.

Introduction
This standard is a Type C Standard as stated in EN ISO 12100-2.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this standard.
When the provisions of this C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines
that have been designed and built according to the provisions of this type C standard.
The purpose of this standard is to define safety requirements for escalators and moving walks in order to
safeguard people and objects against risks of accidents during installation, operation, maintenance and
inspection work.
It is assumed that negotiations have been made for each contract between the customer and the
supplier/installer (see also Annex A) about:
a) intended use of the escalator or moving walk;
b) environmental conditions;
c) civil engineering problems;
d) other aspects related to the place of installation.
(0.5.2) If escalators or moving walks are intended to be operated under special conditions, such as directly
exposed to the weather or explosive atmosphere, or in exceptional cases serve as emergency exits,
appropriate design criteria, components, materials and instructions for use should be used that satisfy the
particular conditions.
(0.8) An Interpretation Committee has been established to clarify, if necessary, the spirit in which the clauses
of the standard have been drafted and to specify the requirements appropriate to particular cases. (new)The
formats of an interpretation request and the interpretation are given in Annex K.

4 List of significant hazards
This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with
in this standard, identified by risk assessment as significant for escalators and moving walks and which
require action to eliminate or reduce the risk. These significant hazards are based upon EN 1050.
4.1 Mechanical hazards
Mechanical hazards on escalators and moving walks and in their immediate vicinity can occur because of the
design of the machine or access to it.
These include:
contact with moving machinery parts (e.g. driving unit, handrail drive) normally not accessible to the
public;
crushing of fingers between handrail and balustrade;
10
---------------------- Page: 11 ----------------------
prEN 115:2005 (E)
impact on bodies caused by collision with building structures (wall, roof, criss-cross arrangement), or with
persons on adjacent escalators/moving walks;
drawing-in at handrail entry into the balustrade;
trapping between skirting and steps, between comb and step/pallet;
trapping between step and step or pallet and pallet.
4.2 Electrical hazards
Electrical hazardous situations can occur due to:
contact of persons (workers) with live parts;
inadequate emergency stops;
wrong assembly of electrical components;
electrostatic phenomena;
external influences on electrical equipment.
4.3 Radiation hazards
4.3.1 Electromagnetic radiation generated by the machine
Electromagnetic radiation can be emitted by the escalator or moving walk during normal operation.
4.3.2 Electromagnetic radiation received from outside
Immission of low frequency radiation, radio frequency radiation, and microwaves can occur.
4.4 Fire hazard
Fire hazards can be generated by accumulation of combustible material inside the truss, by the isolation
material for cables and overloading of drives.
4.5 Hazards generated by neglecting ergonomic principles in machinery design
Hazardous situation can occur because of:
neglecting ergonomic dimensions for the users (e.g. height of balustrade, width of handrail);
inadequate lighting in the working places and access to it;
insufficient space in working places;
missing lifting equipment for heavy loads.
4.6 Failure of control circuit
Hazardous situation can occur because of:
no stopping in case of dangerous situations;
11
---------------------- Page: 12 ----------------------
prEN 115:2005 (E)
short circuit of electrical wiring;
overload of electrical wiring;
unexpected start of machine after an interruption;
unexpected reversal of drive;
excessive speed;
excessive deceleration during stopping.
4.7 Break-up during operation
Even if the design of an escalator or moving walks follows the requirements of EN 115, there are specific
hazards which can occur due to
greater than specified user and structural loads on the truss;
loads greater than specified onto the balustrade;
loads greater than specified on the steps/pallets by unforeseeable misuse;
loads greater than specified on the drive unit.
4.8 Slip, trip and fall of persons
Most of the dangerous situations on escalators and moving walks are caused by slipping and falling of
persons.
This includes:
slipping on steps/pallets/belt, on the comb plate;
falling caused by handrail speed deviation (incl. standstill);
falling caused by change of the direction of movement;
falling caused by increased acceleration/deceleration;
falling caused by unexpected start or over-speed of the machine;
falling caused by inadequate lighting at the landings.
4.9 Particular hazards in combination with this type of machine
Many hazards are specific for that type of machine. These include
missing steps or pallets after maintenance/repair work;
misuse by transporting others items than persons (e.g. shopping or luggage trolleys);
climbing on the outside of the balustrade;
climbing over the balustrade;
12
---------------------- Page: 13 ----------------------
prEN 115:2005 (E)
surfing on the handrail;
storage of merchandise adjacent to the balustrade,
creation of traffic jam at blocked landings or intermediate exits of consecutive escalators or moving walks;
disturbance of the person flow in connected escalators/moving walks;
lifting by the handrail at the newel ends and falling over adjacent fixed barrier or the balustrade of the
escalator/moving walk.
5 Safety requirements and/or protective measures
5.1 General
Escalators and moving walks shall comply with the safety requirements and/or protective measures of this
clause. In addition, escalators and moving walks shall be designed according to the principles of
EN ISO 12100-2 for relevant but not significant hazards, which are not dealt with by this standard (e.g. sharp
edges).
Where, for elucidation of the text, an example is given this shall not be considered as the only possible design.
Any other solution leading to the same result is permissible if it is ensured that with an equivalent function the
same safety level exists.
Certain escalators and moving walks are subject to special operational and environmental conditions. For
these cases some additional recommendations are defined (see Annex G.2).
5.2 Supporting structure (truss) and enclosure
5.2.1 General
5.2.1.1 All mechanically moving parts of the escalator or moving walk shall be completely enclosed within
imperforate 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. Apertures for ventilation are permitted (see also
5.2.1.5)
5.2.1.2 The exterior panels shall withstand a force of 250 N at any point at right angles on an area of
25 cm². The supporting structure and fixing points shall be designed in that way to carry at least twice the
dead load of the enclosure.
