ASSESSED HAZARDS Let us no linger in reporting the basic table of the standard while we will only list the hazards of the recently published version (2019) added to those already included in the 2003 version. 1.3 Inadequate firefighters lift 1.5 No or inadequate earthquake resistance 2.19 Too large distance between leading edges of car and landing doors 4.4 Inadequate strength of car doors 4.11 No or inadequate protective device (150 N) for re-opening of power operated doors other than sliding doors 4.21 No car door restrictor where the landing door locking device is accessible when the car door is opened outside of the door zone 5.9 No emergency lighting on the car roof 8.1 Inadequate machine brake (only one brake set) 9.5 No or inadequate stopping device at the machine in the machinery space 10.1 No earth fault protection in circuits with electric safety devices or in circuits controlling the brake or the down valve 10.5 No or inadequate inspection control station in the pit. CONCLUSIONS We suggest our kind readers a careful examination of EN 81-80:2019 Standard which, although not harmonised because it does not refer to new installations, is of considerable importance to help remove the disparity existing in our country with regard to the safety of lift users who, on a hypothetical scale from 1 to 10, may find lifts with a very low (towards zero) or - fortunately - very high (towards 10) level. The new version of the EN 81-80 European Standard can give an important contribution to the movement already existing, but never supported by the Authorities in our country, to remove from service those lifts which are not very safe and in any case with an absolutely insufficient level of safety. Reading the hazards foreseen by the standard brings information, analysis and answers to the issue. • PERICOLI ESAMINATI Non ci soffermiamo a riportare la tabella fondamentale della norma e ci limitiamo a indicare i rischi che la versione recentemente pubblicata (2019) ha aggiunto a quelli già previsti dalla versione del 2003. 1.3 Ascensore antincendio non adeguato 1.5 Comportamento antisismico non adeguato o non esistente 2.19 Eccessiva distanza orizzontale tra ante delle porte di cabina e di piano 4.4 Resistenza inadeguata delle porte di cabina 4.11 Protezione assente o inadeguata (150 N) per riapertura porte automatiche scorrevoli orizzontali 4.21 Assenza «RESTRICTOR» se serratura porta di piano è accessibile se porta di cabina aperta fuori della zona porte 5.9 Assenza di illuminazione di emergenza sul tetto della cabina 8.1 Freno non adeguato (solo 1 elemento) 9.5 Assenza o inadeguatezza dell’interruttore di arresto della macchina (nello spazio del macchinario) 10.1 Nessuna protezione contro guasto a terra in circuiti con DES o di controllo del freno o della valvola di discesa 10.5 Assenza o inadeguatezza del commutatore di ispezione nella fossa del vano di corsa. CONCLUSIONI Suggeriamo ai nostri cortesi lettori un attento esame della Norma EN 81-80:2019 che, pur non essendo armonizzata perché non riferita a nuove installazioni, riveste una notevole importanza per contribuire all’eliminazione della disparità che nel nostro Paese esiste per quanto riguarda la sicurezza degli utenti degli ascensori che, in un’ipotetica scala da 1 a 10, possono trovare ascensori con un livello molto basso (verso lo zero) oppure – fortunatamente – molto alto (verso il 10). La nuova versione della Norma europea EN 81-80 può dare un importante contributo al movimento già esistente, ma mai aiutato nel nostro Paese dalle Autorità, per eliminare dal servizio ascensori certamente poco sicuri e comunque con un livello di sicurezza assolutamente insufficiente. La lettura dei pericoli previsti dalla norma porta informazioni, analisi e risposte al problema. • Translated by Paola Grassi 60 ELEVATORIMAGAZINE.COM NOVEMBER | DECEMBER • NOVEMBRE | DICEMBRE
