Omkring 10.000 til 33.000 arbejdere i EU uds\u00e6ttes for akrylonitril p\u00e5 deres arbejdsplads. Ind\u00e5nding betragtes som den prim\u00e6re eksponeringsvej, selvom arbejdere ogs\u00e5 kan blive eksponeret ved hudkontakt, da akrylonitril let kan tr\u00e6nge igennem huden. <\/p>\n

Akrylonitril er klassificeret som carcinogen kategori 1B (i henhold til CLP-forordningen), hvilket betyder, at det formodes at have carcinogent potentiale for mennesker, baseret p\u00e5 dokumentation fra dyr. Eksponering for akrylonitril kan for\u00e5rsage lungekr\u00e6ft, og der er tegn p\u00e5, at akrylonitril kan for\u00e5rsage bl\u00e6rekr\u00e6ft. <\/p><\/blockquote>\n

Hvor risici opst\u00e5r<\/h2>\n

Den prim\u00e6re anvendelse af akrylonitril er som r\u00e5materiale til fremstilling af tekstilfibre af akryl og modakryl. Andre vigtige anvendelser omfatter fremstilling af kemikalier, gummiprodukter og plastprodukter; akrylonitril og styren bruges ogs\u00e5 sammen i produktionen af styren-akrylonitril (SAN) og akrylonitril-butadien-styren (ABS)-harpikser. <\/p>\n

Mere om stoffet<\/h2>\n

Ved normal temperatur og tryk er akrylonitril en klar, farvel\u00f8s v\u00e6ske, der har en stikkende lugt. Sm\u00e5 m\u00e6ngder akrylonitril frigives under forbr\u00e6nding af plantemateriale som biomasse, tr\u00e6 og tobak. Akrylonitril bruges i vid udstr\u00e6kning i fly-, forsvars-, rumfarts- og bilindustrien. <\/p>\n

Farer, der kan opst\u00e5<\/h2>\n

N\u00e5r det ind\u00e5ndes eller absorberes via hudkontakt, er det prim\u00e6re m\u00e5l for toksicitet centralnervesystemet.<\/p>\n

Akrylonitril kan ogs\u00e5 lokalt irritere hud, \u00f8jne og luftveje og give hudsensibilisering. En del af denne toksicitet skyldes metabolismen af akrylonitril til cyanid. <\/p>\n

Ved h\u00f8jere eksponeringsniveauer er Akrylonitril ogs\u00e5 forbundet med andre virkninger som svaghed i lemmerne, besv\u00e6ret vejrtr\u00e6kning, svimmelhed, nedsat d\u00f8mmekraft, cyanose og kvalme til kollaps, uregelm\u00e6ssig vejrtr\u00e6kning og kramper, afh\u00e6ngigt af dosis og varighed af eksponeringen.<\/p>\n

Akut ind\u00e5ndingseksponering for flydende eller dampformede akrylonitriler (ofte som f\u00f8lge af utilsigtet udslip) er blevet forbundet med en r\u00e6kke virkninger, herunder irritation af slimhinderne i n\u00e6se, \u00f8jne og \u00f8vre luftveje.<\/p>\n

Med hensyn til latenstiden mellem eksponering og Akrylonitril-relateret hjernekr\u00e6ft er der tale om en latenstid p\u00e5 30 \u00e5r.<\/strong><\/p>\n

Hvad du kan g\u00f8re<\/h2>\n

P\u00e5 arbejdspladsen er den mest effektive m\u00e5de at forhindre eksponering p\u00e5 at erstatte akrylonitril, f.eks. kan det ved fremstilling af ABS erstattes af methacrylonitril (2-methyl-2-propen-nitril). Hvis substitution af akrylonitril ikke er mulig, og brug af akrylonitril ikke kan undg\u00e5s, skal der tr\u00e6ffes foranstaltninger til at reducere eksponeringen. <\/p>\n

Den mest effektive m\u00e5de at undg\u00e5 eksponering for akrylonitril p\u00e5 er at udvikle og bruge lukkede systemer. Hvor dette ikke er muligt, skal tekniske foranstaltninger s\u00e5som effektiv lokal udsugning suppleret med god ventilation af arbejdspladsen samt kontrol af deres effektivitet implementeres for at sikre, at eksponeringen minimeres s\u00e5 meget som teknisk muligt. <\/p>\n

Gennemf\u00f8r regelm\u00e6ssige eksponeringsvurderinger for at kontrollere, om dine beskyttelsesforanstaltninger er effektive, eller om der skal tr\u00e6ffes yderligere foranstaltninger. Arbejderne skal v\u00e6re opm\u00e6rksomme p\u00e5 virkningerne af eksponering og b\u00f8r uddannes regelm\u00e6ssigt i de kontrolforanstaltninger, der er n\u00f8dvendige for at arbejde sikkert med Akrylonitril for at forhindre eksponering. Det anbefales at inddrage en arbejdsmediciner. <\/p>\n

S\u00f8rg for, at arbejderne har tilstr\u00e6kkelig personlig beskyttelse, f.eks. beskyttelsest\u00f8j og handsker, hvis det er n\u00f8dvendigt. Personlig beskyttelse b\u00f8r ikke bruges som den eneste forebyggende foranstaltning. S\u00e5 mange af de ovenn\u00e6vnte tekniske og organisatoriske foranstaltninger som muligt skal v\u00e6re gennemf\u00f8rt p\u00e5 forh\u00e5nd. S\u00f8rg for, at der bruges den rigtige personlige beskyttelse, f.eks. \u00f8jen- og ansigtsbeskyttelse, handsker, beskyttelsest\u00f8j og \u00e5ndedr\u00e6tsv\u00e6rn. Derudover skal der ved valg af udstyr tages hensyn til anatomien hos de arbejdere, der skal bruge det, og i tilf\u00e6lde af \u00e5ndedr\u00e6tsv\u00e6rn baseret p\u00e5 ansigtstilpasning anbefales det st\u00e6rkt, at der udf\u00f8res en tilpasningstest p\u00e5 hver person. Derudover skal alle arbejdere instrueres i at vaske deres h\u00e6nder ordentligt, f\u00f8r de holder pause eller g\u00e5r ind i et andet omr\u00e5de, og i at vaske sig selv og skifte t\u00f8j ved slutningen af hvert skift. <\/p>\n

Personlig beskyttelse b\u00f8r kun bruges som en sidste udvej og kun overvejes midlertidigt, efter at de mulige tekniske l\u00f8sninger er udt\u00f8mt. Arbejderne b\u00f8r modtage den n\u00f8dvendige uddannelse og information om korrekt brug og vedligeholdelse af personlige v\u00e6rnemidler. <\/p>\n
