Trestøv i arbeidsmiljøet

Behov for ny kunnskap

Problemet med trestøv er knyttet til HMS og innånding av støvpartikler. Trestøvprosjektet utvikler ny kunnskap om hvordan ventilering, oppvarming og produksjon henger sammen med trestøveksponering for arbeidstakere i produksjonsbedrifter som bearbeider trebaserte materialer

Trestøv er et problem for all industri med bearbeiding av trebaserte materialer. Trestøvet må fjernes fra luften, og frisk luft tilføres. I tillegg er det ofte behov for at luften i produksjonslokalene har stabil temperatur og fuktighet for at trevirke ikke skal slå seg. Når avtrekksvolumet normalt er mye større enn nødvendig volum for friskluft for arbeidstakerne blir dette en krevende situasjon. Løsningen for mange bedrifter har derfor vært å filtrere og resirkulere luften i produksjonslokalene for å unngå kostbare og overdimensjonerte ventilasjonsanlegg og for å holde oppvarmingskostnadene nede.

Trestøvprosjektet ble etablert i et samarbeid mellom byggenæringens IA-program, Arbeidstilsynet, Statens arbeidsmiljøinstitutt (STAMI), LO og bransjeorganisasjonene Norske Trevarer og Boligprodusentenes Forening. Formålet med prosjektet er å bidra til ny kunnskap om forekomst av trestøv i trebearbeidende industri.

Et tredvetalls industribedrifter er tilknyttet prosjektet og gjennomfører sine egne målinger av trestøv som blir tilgjengelig for forskerne i STAMI. Det er særlig interesse knyttet til eventuelle effekter som følge av resirkulering av luft i produksjonslokaler, siden dette er en mye brukt løsning for å spare energi i vintersesongen.

Data om trestøv i industriproduksjonen blir innhentet dels ved at bedriftene som deltar i prosjektet gjør sine måleresultater tilgjengelig for STAMI og dels ved at STAMI gjennomfører egne målinger i et utvalg av bedriftene.

 

 

Erfaringene fra prosjektet vil danne grunnlag for eventuelle endringer i regelverket etter arbeidsmiljøloven. Ta gjerne kontakt med Trestøvprosjektet. Du finner kontaktpersoner på prosjektets hjemmeside: https://www.norsketrevarer.no/om-oss/prosjekter/trestov/
