L-i\u017coprin jintu\u017ca b\u0127ala monomeru fil-produzzjoni u l-ippro\u010bessar tal-polimeri. Barra minn hekk, jintu\u017ca b\u0127ala intermedju fis-sintesi ta\u2019 sustanzi kimi\u010bi. L-espo\u017cizzjoni tista\u2019 sse\u0127\u0127 ukoll waqt il-manifattura tal-isoprene jew meta jintu\u017ca b\u0127ala fjuwil sostenibbli g\u0127all-avjazzjoni.

Aktar dwar is-sustanza<\/h2>\n

L-i\u017coprin huwa likwidu fjammabbli bla kulur b’ri\u0127a \u0127afifa. G\u0127andu punt ta’ tog\u0127lija baxx ta’ 34\u00b0C biss u g\u0127alhekk pressjoni tal-fwar estremament g\u0127olja ta’ 634 hPa di\u0121\u00e0 f’21.1 \u00b0C. Dan ifisser li jevapora malajr f’temperatura tal-kamra. Il-fwar rilaxxat jista’ ji\u0121i inalat jew jo\u0127loq atmosfera splussiva. L-i\u017coprin huwa metabolit li jse\u0127\u0127 b’mod naturali f’\u0127afna pjanti, annimali u bnedmin. L-i\u017coprin ji\u0121i emess minn \u0127afna spe\u010bi ta’ si\u0121ar f’ammonti kbar (i\u017cda jiddegrada malajr, li jfisser li l-kon\u010bentrazzjonijiet ambjentali huma baxxi) u jista’ ji\u0121i skopert ukoll fin-nifs tal-bniedem. L-i\u017coprin nnifsu mhuwiex \u0121enotossiku, i\u017cda ji\u0121i metabolizzat fa\u010bilment g\u0127al mono- u diepossidu \u0121enotossiku, predominantement fil-fwied. Il-polimeri tal-i\u017coprin huma l-komponent ewlieni tal-gomma naturali. L-aktar prodotti komuni mag\u0127mula mill-isoprene huma t-tajers. <\/p>\n

L-og\u0127la potenzjal g\u0127al espo\u017cizzjoni relatati max-xog\u0127ol g\u0127all-i\u017coprin huwa permezz tal-inalazzjoni tal-fwar. Espo\u017cizzjoni wa\u0127da jew g\u0127al \u017cmien qasir g\u0127all-isoprene tista’ tikkaw\u017ca irritazzjoni tal-imnie\u0127er, il-ger\u017cuma u l-pulmuni, u tista’ twassal g\u0127al u\u0121ig\u0127 ta’ ras jew sturdament. Filwaqt li t-tossi\u010bit\u00e0 akuta hija baxxa (ji\u0121ifieri, huwa improbabbli \u0127afna li wie\u0127ed imut minn espo\u017cizzjoni wa\u0127da g\u0127al \u017cmien qasir), espo\u017cizzjoni fit-tul jew ripetuta g\u0127all-isoprene hija asso\u010bjata ma’ kan\u010ber tal-fwied, de\u0121enerazzjoni tal-epitelju olfattiv u de\u0121enerazzjoni tal-materja bajda tal-korda spinali. <\/p>\n

Dak li tista’ tag\u0127mel<\/h2>\n

L-aktar mod effettiv biex ti\u0121i evitata l-espo\u017cizzjoni huwa s-sostituzzjoni tal-i\u017coprin b’alternattivi aktar sikuri. Fejn is-sostituzzjoni tal-i\u017coprin ma tkunx possibbli u l-u\u017cu tal-i\u017coprin ma jistax ji\u0121i evitat, iridu jittie\u0127du mi\u017curi biex titnaqqas l-espo\u017cizzjoni. Fis-settur tal-manifattura ta’ prodotti petroliferi raffinati, li huwa responsabbli g\u0127all-produzzjoni u mhux g\u0127all-u\u017cu tal-isoprene, is-sostituzzjoni mhijiex applikabbli. Madankollu, l-u\u017cu ta’ monomeri o\u0127ra fl-industrija tal-gomma jista’ jkun g\u0127a\u017cla. It-tieni l-aktar mod effettiv biex ti\u0121i evitata l-espo\u017cizzjoni g\u0127all-isoprene huwa li ji\u0121u \u017cviluppati u u\u017cati sistemi mag\u0127luqa. Sistemi mag\u0127luqa jinstabu komunement fil-pro\u010bessi kollha ta’ produzzjoni kemm fir-raffinar kif ukoll fil-polimerizzazzjoni tal-i\u017coprin. <\/p>\n

Fejn is-sostituzzjoni jew pro\u010bess mag\u0127luq ma jkunux possibbli, g\u0127andhom ji\u0121u implimentati mi\u017curi tekni\u010bi b\u0127al ventilazzjoni lokali effettiva tal-eg\u017cost, jew ventilazzjoni tajba tal-post tax-xog\u0127ol kif ukoll il-verifika tal-effettivit\u00e0 tag\u0127hom biex ji\u0121i \u017cgurat li l-espo\u017cizzjoni ti\u0121i minimizzata kemm jista’ jkun teknikament possibbli. L-i\u017coprin \u0127afna drabi ji\u0121i ppro\u010bessat f’kabini ta’ kontroll bi pressjoni, li huma effi\u010bjenti \u0127afna fit-tnaqqis tal-evaporazzjoni. <\/p>\n

Implimenta evalwazzjonijiet regolari tal-espo\u017cizzjoni biex tivverifika jekk il-mi\u017curi protettivi tieg\u0127ek fis-se\u0127\u0127 humiex effettivi jew jekk hemmx b\u017conn li jittie\u0127du aktar azzjonijiet.

Huwa rakkomandat li tinvolvi tabib. <\/p>\n
