Ta evropski standard določa načrtovanje in izdelavo polnilnikov večetažnih peči, ki so v uporabi v prehrambeni industriji, pekarnah, izdelavi peciv, itd. Ti stroji so uporabljeni za prenos kosov testa na posamezno etažo večetažnih peči in za odstranitev pečenih proizvodov iz posamezne etaže. Ta oprema je lahko: - ročna; - polavtomatska (nekateri pomiki gnani, nekateri pomiki potrebujejo ročno moč). Evropski standard zajema tehnične zahteve za varnost in higieno za načrtovanje, namestitev, nastavitev, delovanje, čiščenje in vzdrževanje te opreme. Ta evropski standard obravnava velike nevarnosti, nevarne situacije in primere, ki se tičejo polnilnikov večetažnih peči, kadar se uporabljajo, kot predvideno, in pod pogoji napačne uporabe, ki jih razumno predvidi proizvajalec (glej Klavzulo 4). Hrup iz polnilnikov večetažnih peči ne šteje za veliko nevarnost. To ne pomeni, da je proizvajalec stroja oproščen zmanjševanja hrupa in priprave deklaracije o hrupu. Zato je preskusna koda hrupa podana v Dodatku A. Izvzeta je naslednja oprema: - preskusna oprema in oprema, ki jo razvija proizvajalec; - polnilniki za peči s transportnim jermenom; - polnilniki, vgrajeni v peči; - popolnoma samodejni polnilniki večetažnih peči. Ta evropski standard ne velja za polnilnike večetažnih peči, ki so bili izdelane pred datumom, ko je CEN objavil ta evropski standard.

Before using this document it is important to carry out a risk assessment of the fixed deck oven loaders to check that it has the hazards identified in this clause. 4.2 Mechanical hazards The significant mechanical hazards are: abrasion hazard; shearing hazard; crushing hazard; impact hazard; drawing-in hazard; loss of stability. Zone 1: range of movement of loading device and its belt in relation to its support: fixed table (abrasion and shearing hazards). Zone 2: range of lifting movement of oven loader (shearing hazard due to access to scissors mechanism and crushing hazards for mast systems). Zone 3: space below oven loader when lifting: deck oven loader support, oven loader and belt (crushing and impact hazards in the event of failure and falling). Zone 4: range of movement of the castors (crushing and impact hazards). Zone 5: oven deck loader drive mechanisms (type 2 and 3 oven deck loaders), lifting movement mechanisms (type 3 and 4 deck oven loaders), shifting movement mechanisms (type 5 deck oven loaders only): crushing, shearing and drawing-in hazards. Zone 6: range of movement of the equipment (crushing and impact hazards including in the event of the loss of stability or failure). Figure 2a (scissors system) and Figure 2b (mast system) show the danger zones. SIST EN 13591:2006+A1:2010

a) Danger zones – Scissors system
b) Danger zones – Mast system Figure 2 — Danger zones for scissors and mast systems 4.3 Electrical hazards Hazard of electric shock from direct or indirect contact with live components. Hazard from external influences on electrical equipment (e.g. cleaning with water, dust). During the movements of the equipment, there is a risk due to the damaging of the supply cable (e.g. short circuit). 4.4 Hazard generated by neglecting hygienic design principles The neglect of hygienic principles can create unacceptable modification of foodstuff and therefore a risk to human health, i.e. through physical, chemical or microbial pollution. SIST EN 13591:2006+A1:2010
EN 13591:2005+A1:2009 (E) 12 4.5 Hazards generated by neglecting ergonomic principles During operation, cleaning and maintenance there is a risk of injury or chronic damage to the body resulting from awkward body postures. Working on an oven deck loader may involve various repetitive hand and arm movements (loading the dough pieces, positioning and moving the equipment, as well as loading in the oven), which may cause repetitive strain injury. 4.6 Pneumatic and hydraulic equipment Pneumatic and hydraulic equipment presents crushing, shearing, ejection of parts, explosion and injection of fluids hazards. Stored energy in pneumatic or hydraulic systems may cause mechanisms to move unexpectedly even when power supplies are disconnected. 5 Safety and hygiene requirements and/or protective measures 5.1 General Machinery shall comply with the safety and hygiene requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges). NOTE For hazards which are to be reduced by the application of type B standards such as EN 574, EN 614-1, EN 953, !EN ISO 13849-1", EN 982, EN 983, EN 1037, EN 1088and EN 60204-1, the manufacturer should carry out a risk assessment to establish the requirements of that standard which are to be applied. This specific risk assessment is part of the general risk assessment of the machine.
Where the means of reducing the risk is by the physical arrangement or positioning of the installed machine, the manufacturer shall include in the information for use a reference to the reduction means to be provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification.
Where the means of reducing the risk is by a safe system of working the machinery, the manufacturer shall include in the information for use details of the system and of the elements of training required by the operating personnel. 5.2 Mechanical hazards 5.2.1 General !The safety related parts of the control systems shall present at least a performance level c defined in accordance with EN ISO 13849-1:2008. Unless otherwise specified, interlocking guards shall be at least interlocking without guard locking as defined in EN 1088:1995, 4.2.1 and they shall comply with EN 1088:1995, Clauses 5 and 6. When fixed guards, or parts of the machine acting as such, are not permanently fixed e. g. by welding, their fixing systems shall remain attached to the guards or to the machinery when the guards are removed." 5.2.2 Zone 1: Range of movement of oven loader and its belt, in relation to its support 5.2.2.1 Type 1 and 4 fixed deck oven loaders: Manual loading in the oven The gap between the oven loader (L2 in Figure 3) handle and any fixed part of the frame shall be greater than or equal to 40 mm. SIST EN 13591:2006+A1:2010
EN 13591:2005+A1:2009 (E) 13 NOTE EN 349:1993, Table 1 recommends 25 mm in order to avoid crushing fingers. Since the operator may wear gloves, this is not considered sufficient for the abrasion hazard. Additionally, if the oven loader handle is on the side of the oven loader, its minimum length shall be 150 mm and a guard with a minimum diameter of 50 mm shall be placed between the handle and the frame (see Figure 3), in order to keep the hand (including the thumb) well away from the frame.
L1 ≥ 150 mm L2 ≥ 40 mm D ≥ 50 mm Figure 3 — Oven loader handle 5.2.2.2 Type 2 and 3 oven deck loaders: Mechanically operated loading in the oven The oven loading control shall require the use of both hands. This can be achieved by using a two hand control device in accordance with type II of EN 574. It shall not be possible to actuate both push-buttons with one hand. This could be achieved by ensuring that a distance greater than or equal to 260 mm separates the two push-buttons (e.g. see 8.2 or equivalent solutions according to Annex A of EN 574:1996). Figure 4a illustrates this solution. Access to the in-running nip of the loading device shall be prevented, e.g. by a guard such as the one marked (c) in Figure 4b. SIST EN 13591:2006+A1:2010
