Ocenjuje se, da je pribli\u017eno 3 milijone zaposlenih v EU izpostavljenih lesnemu prahu. Dolgotrajna exposure lesnemu prahu lahko povzro\u010di raka na nosu in obnosnih votlinah. IARC uvr\u0161\u010da lesni prah med rakotvorne snovi skupine 1, kar pomeni, da velja za zanesljivega povzro\u010ditelja raka pri ljudeh.<\/p><\/blockquote>\n

Kje se pojavljajo tveganja<\/h2>\n

Najvi\u0161je ravni exposure so na splo\u0161no pri poklicih, povezanih z obdelavo in predelavo lesa, kot so upravljavci brusilnikov, poklici za tiskarska dela v industriji lesnih izdelkov in upravljavci stru\u017enic. Vendar se lahko exposure lesnemu prahu pojavi pri katerem koli delu ali postopku, ki sestavlja \u017eivljenjski cikel lesnih izdelkov, od se\u010dnje do vgradnje in kon\u010dne obdelave. Primeri exposure so gradbeni\u0161tvo stavb in ladij, gozdarstvo in mizarstvo.<\/p>\n

Ve\u010d o snovi<\/h2>\n

Lesni prah nastane, ko se stroji ali orodja uporabljajo za rezanje ali oblikovanje trdega lesa. Velike koli\u010dine lesa pra\u0161kov na primer nastajajo v \u017eagah. Ve\u010dji pra\u0161ni delci se zadr\u017eujejo v nosu in nosnih dihalnih poteh ter lahko povzro\u010dijo raka na nosu. Manj\u0161i delci lahko prodrejo globlje v plju\u010da in povzro\u010dijo astmo, alveolitis in druge plju\u010dne patologije. Ta zelo fini prah nastaja predvsem med bru\u0161enjem ali rezanjem in je najbolj nevaren. Droben prah se pri rezanju \u0161iri tudi naprej. Koli\u010dina in vrsta spro\u0161\u010denega lesnega prahu sta odvisni od lesa, ki se obdeluje, stroja, ki se uporablja, in name\u0161\u010denih ukrepov za obvladovanje tveganja.<\/p>\n

V veljavi je zavezujo\u010da poklicna meja exposure EU 2 mg\/m\u00b3 (\u010dasovno tehtano povpre\u010dje).<\/p>\n

Nevarnosti, ki se lahko pojavijo<\/h2>\n

Ko zaposleni vdihujejo lesni prah, se ta odlaga v nosu, grlu in drugih dihalnih poteh. Exposure lesnemu prahu lahko povzro\u010di bolezni dihal, dra\u017eenje o\u010di, ko\u017ene bolezni in v primeru dolgotrajne exposure raka. Dodatno tveganje pri obdelavi lesa je, da lahko leseni predmeti vsebujejo druge nevarne snovi. Pri izdelavi ve\u010dine plo\u0161\u010d se na primer uporabljajo smole, ki vsebujejo formaldehid. So\u010dasna exposure lesnemu prahu in formaldehidu pove\u010da tveganje za nazofaringealni rak.<\/p>\n

Latenca med exposure in rakom nosu, povezanim z lesnim prahom, je ocenjena na vsaj 20 let.<\/strong><\/p>\n

Kaj lahko storite<\/h2>\n

Exposure se lahko zmanj\u0161a z zavestnim izborom vrst lesa, opreme in delovnih tehnik. Lokalizirane ekstrakcijske naprave je treba redno preverjati. Idealno bi bilo uporabljati stroje za obdelavo lesa z integriranimi ekstrakcijskimi sistemi. Stroji bi morali imeti tudi program preventivnega vzdr\u017eevanja, da se zagotovi pravilno delovanje skozi celotno \u017eivljenjsko dobo sistema. Redno izvajajte ustrezne meritve exposure, da boste vedeli, kdaj in kje je treba ukrepati. Preverite, ali zaposleni poro\u010dajo o respiratornih simptomih, in vklju\u010dite zdravnika medicine dela. Najbolj\u0161a re\u0161itev je nadzor exposure z oblikovanjem in in\u017eenirskimi spremembami, kot je namestitev izpu\u0161nega prezra\u010devalnega sistema z zbiralniki, name\u0161\u010denimi na mestih, kjer nastaja prah.<\/p>\n

Higiena na delovnem mestu, kot je odstranjevanje prahu z miz in tal, je pomemben in klju\u010den organizacijski ukrep. \u010ci\u0161\u010denje prahu je treba izvajati tako, da se prepre\u010di exposure in \u0161irjenje prahu z uporabo industrijskih sesalnikov s filtri HEPA in vedno izogibanjem suhemu pometanju in uporabi stisnjenega zraka.<\/p>\n

Zaposlene nenehno ozave\u0161\u010dajte o u\u010dinkih exposure. Poleg tega zaposlene usposobite o nevarnostih, varnih delovnih praksah in u\u010dinkovitih higienskih ukrepih. Osebna varovalna oprema, kot so respiratorji, je kratkoro\u010dna re\u0161itev za zmanj\u0161anje exposure in se sme uporabljati le kot zadnja mo\u017enost.<\/p>\n
