Abstract

Leta 2010 je bila narejena raziskava obremenitev gozdnih delavcev z ropotom pri različnih delovnih fazah gozdne proizvodnje. Raziskovalni objekti so se nahajali na območju visokega krasa na GGO Kočevje. Obremenitve z ropotom pri klasični sečnji in spravilu ter strojni sečnji in spravilu so bile merjene pri delu z motorno žago, zgibnim traktorjem, strojem za sečnjo ter zgibnim polprikoličarjem. V raziskavi so obravnavane obremenitve z ropotom po delovnih operacijah, izračunane modelne 8-urne vrednosti obremenitve z ropotom, ki so primerjane z veljavno zakonodajo. Ugotovitve kažejo, da obremenitve z ropotom pri sečnji z motorno žago (95,6 dB(A)) ter spravilu lesa z zgibnim traktorjem (83,8 dB(A)) presegajo spodnjo opozorilno mejo dnevne izpostavljenosti (80 dB(A)), pri sečnji z motorno žago pa tudi zgornjo opozorilno izpostavljenost ropotu. Nasprotno pa pri strojni sečnji (68,2 dB(A)) in spravilu lesa (66,9 dB(A)), obremenitve z ropotom ne presegajo dnevnih opozorilnih vrednosti izpostavljenosti.

Secondary title:	Noise loads of workers at forest operations
Secondary abstract:	Researches were made in year 2010 on chainsaw operator, tractor driver, harvester operator and forwarder operator. Objects were located at the area of Slovenian high carst in GGO Kočevje. Noise loads were measured by felling on chainsaw and harvester and by timber harvest on skidder and forwarder. This gradual thesis presents overall structure of loads by noise by working operations and modular loads (8h). Calculated modular loads by noise were compared with valid standards. The analyzes of results show us that noise loads emited by chainsaw (95,6 dB(A)) and by tractor (83,8 dB(A)) were above lower day limit of noise exposure (80 dB(A)). On the other hand, harvester operator (68,2 dB(A)) and forwarder operator (66,9 dB(A)) were not over loaded by noise.
