SIST EN 115-1:2009

Some individuals, in particular older people, might have more than one impairment. Some individuals are not able to use an escalator or moving walk independently and rely on assistance/support being provided by a companion. Furthermore some individuals can be encumbered by objects or be responsible for other persons, which can affect their mobility. The extent to which an individual is incapacitated by impairments and encumbrances often depends on the usability of products, facilities and the environment. The use of wheelchairs on escalators and moving walks can lead to dangerous situations which cannot be mitigated by machine designs and therefore should not be permitted. The use of lifts is the preferred method of vertical travel for most people with disabilities and in particular wheelchair users and persons with guide dogs. Additional signs should be provided to indicate the location of other facilities, these facilities should be in close proximity to the escalators and moving walks and easy to find.
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. 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.
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. Interpretation Requests can be sent to the National Standard Bodies which will contact the responsible Technical Committee CEN/TC 10. The formats of an interpretation request and the interpretation are given in Annex L. SIST EN 115-1:2009

4 List of significant hazards 4.1 General 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 ISO 14121-1 [2]. SIST EN 115-1:2009

Electromagnetic radiation can be emitted by the escalator or moving walk during normal operation (see 5.11.1.2.3, 5.12.1.2.1.5). 4.4.2 Electromagnetic radiation received from outside Immission of low frequency radiation, radio frequency radiation, and microwaves can occur (see 5.11.1.2.3, 5.12.1.2.1.5). SIST EN 115-1:2009

4.7 Hazard generated by failure of control circuit Hazardous situation can occur because of:  no stopping in case of dangerous situations (see 5.11.2, 5.12.1);  short circuit of electric wiring (see 5.11.1.4, 5.11.6);  overload of electric wiring (see 5.11.3, 5.11.5, 5.4.1.5, 5.12.1, 5.12.2);  unexpected start of machine after an interruption (see 5.4.1.5, 5.12.2);  unexpected reversal of drive (see 5.4.2.3, 5.12.1);  excessive speed (see 5.4.2.3, 5.12.1);  excessive deceleration during stopping (see 5.12.1). 4.8 Hazards generated by break-up during operation Even if the design of an escalator or moving walks follows the requirements of EN 115-1, there are specific hazards which can occur due to  greater than specified user and structural loads on the truss (see 5.2.5);  loads greater than specified onto the balustrade (see 5.5.2.3, 5.5.2.4);  loads greater than specified on the steps/pallets by unforeseeable misuse (see 5.3.3);  loads greater than specified on the drive unit (see 5.4.1.3, 5.4.3, 5.4.4).
4.9 Slipping, tripping and falling hazards Most of the dangerous situations on escalators and moving walks are caused by the slipping and falling of persons. These include: SIST EN 115-1:2009

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 without breakage or deflection resulting in any gap. The fixing shall be designed in that way to carry at least twice the dead load of the enclosure. 5.2.1.3 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. 5.2.1.4 Accumulation of materials (e.g. grease, oil, dust, paper) represents a fire risk. Therefore it shall be possible to clean the inner part of the escalator/moving walk.
5.2.1.5 Ventilation apertures shall be built or arranged in such a way to comply with EN ISO 13857:2006, Table 5. However it shall not be possible to pass a straight rigid rod 10 mm in diameter through the enclosure and to touch any moving part through a ventilation aperture. 5.2.1.6 Any exterior panels which are designed to be opened (e.g. for cleaning purposes) shall be provided with an electric safety device according to Table 6 n). 5.2.2 Angle of inclination The angle of inclination α of the escalator shall not exceed 30°, but for rises h13 not exceeding 6 m and a nominal speed not exceeding 0,50 m/s the angle of inclination is permitted to be increased up to 35° (see α in Figure 2). The angle of inclination of moving walks shall not exceed 12°. 5.2.3 Access to the interior Machinery spaces inside the truss shall only be accessible to authorised persons (e.g. by key, access control). 5.2.4 Inspection covers and floor plates Inspection covers and floor plates shall be provided with a control device according to Table 6 n). It shall only be possible to open inspection covers and floor plates 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. Inspection covers and floor plates shall be imperforate. Inspection covers shall conform to the same conditions as required for the location where they are installed. 5.2.5 Structural design The supporting structure shall be designed in a way that it can support the dead weight of the escalator or moving walk plus a rated load of 5 000 N/m2. It shall be calculated in accordance with EN 1993-1-1. NOTE Load carrying area = (nominal width z1 (see Figure 3) of the escalator or moving walk) x (distance l1 between the supports) (see Figure 2).

NOTE 6 000 N/m2 is derived from a static load of 5 000 N/m2 (see 5.2.5) plus an impact factor of 1,2. To establish the dimensions of the belt and its supporting system, an area of effective width x 1,0 m length shall be taken as a basis for this corresponding load (in addition the requirements of 5.3.3.2.4 shall be complied with). Assembled steps and pallets shall be designed such that all component parts e.g. inserts or fixings are securely attached and do not become loose during their life cycle. The inserts and fixings shall withstand the reaction force of operating the comb/comb plate electric safety device (Table 6 g)). 5.3.3.2 Static test 5.3.3.2.1 Steps The step shall be tested for deflection with a single force of 3 000 N (including weight of the plate) applied perpendicular to the tread surface on a steel plate 0,20 m x 0,30 m in size and at least 25 mm thick, in the centre of the tread surface. The edge of the plate being 0,20 m long shall be arranged parallel to the front edge of the step, the edge of the plate being 0,30 m long at right angles to the front edge of the step. During this test, the deflection measured at the tread surface shall be not more than 4 mm. There shall be no permanent deformation (initial setting tolerances are permitted). The step shall be tested as a whole together with rollers (not rotating), axles or stub shafts (if existing) in a horizontal position (horizontal support) and at the maximum inclination (inclined support) for which the step is to be applied. For all inclinations smaller than the maximum inclination permitted, a new test is not required. A test of the installed step
