Ibicuruzwa byiza nibihamye:
1.Uburozi buke cyane no gukira vuba uburozi, bityo birashobora gukoreshwa nka anesthetic. Kurakara kuruhu na mucus. Imbeba zikuze zikuze umunwa LD50: 1.6mL / kg. ikirere ntarengwa cyemewe cya 500 × 10-6. Igikorwa kigomba kwambara mask ya gaze, ugasanga uburozi bwahise bukurwa aho hantu, kuvura ibimenyetso. Nibura muri chloride ya metani. Umwuka ni anestheque cyane kandi guhumeka kwinshi bizatera uburozi bukabije hamwe nububabare bwamazuru, kubabara umutwe no kuruka. Uburozi budashira butera umutwe, umunaniro, kubura ubushake bwo kurya, impaired haematopoiesis no kugabanya selile zitukura. Liquid methylene chloride itera dermatite iyo ihuye nuruhu. Guhumeka umwuka wa 90.5g / m3 mu mbeba zishe mu minota 90. Amavuta ahumura ni 522mg / m3 hamwe nibishobora kwemerwa cyane kumurimo ni 1740mg / m3.
2. Guhagarara: Birahamye
3.Ibintu bibujijwe: Ibyuma bya Alkali, aluminium
4.Ibisabwa kugirango wirinde guhura: Umuyaga, umwuka mwiza
5.Polymerisation hazard: Non-polymerisation
Gusaba ibicuruzwa:
1. Usibye synthesis ngengabihe, iki gicuruzwa nacyo gikoreshwa cyane nka firime ya selile ya selile, pompe ya selile ya triacetate, kuvoma peteroli, gushiramo amavuta mu gukora aerosole na antibiotike, vitamine, ibibyimba bya steroidal, ndetse no gusukura lacquer hejuru yicyuma no kwangirika no kwangirika no gukuramo firime.
2.Yakoreshejwe muri fumigasi yintete no gukonjesha ibyuma bikonjesha bikabije hamwe nubushyuhe bwo guhumeka. Ikoreshwa nkibikoresho bifasha mugukora polyether urethane ifuro kandi nkibikoresho byo guhumeka polysulfone ifuro.
3.Yakoreshejwe nka solvent, ikuramo na mutagen. Ikoreshwa mubushakashatsi bwibinyabuzima.
4.Bifite ubwishyu bwiza, ni buke buke bwo gutekesha hamwe nuburozi buke no kudashya mumashanyarazi akunze gukoreshwa mumashanyarazi, kandi afite ubwishyu bwiza kubisigazwa byinshi, paraffine hamwe namavuta. Ahanini ikoreshwa nka stripper, peteroli dewaxing solvent, ikuramo ibintu bidahindagurika cyane, ikuramo lanoline mu bwoya hamwe namavuta aribwa muri cocout, solvent ya selile triacetate. Ikoreshwa cyane muri fibre acetate, vinyl chloride fibre fibre, gutunganya no kuzimya umuriro, firigo, urotropine nibindi bikorwa.
5.Bikoreshwa mu nganda za elegitoroniki. Mubisanzwe bikoreshwa nkibikoresho byoza amavuta.
6.Bikoreshwa cyane nka flame retardant solvent hamwe nigituba gito cyane. Usibye koza imashini zikoresha moteri yindege, imashini zisobanutse neza, nibindi, irashobora no gukoreshwa nkibikoresho byo kwambura amarangi, kandi irashobora no kuvangwa nandi mashanyarazi kugirango akoreshwe mu koza inganda zitandukanye.
7.Ikindi kandi gikoreshwa nka etyl ester fibre solvent, anesthetic y amenyo yaho, firigo hamwe nu kuzimya umuriro, nibindi, nibisanzwe byerekana gutandukanya chromatografique no gutandukanya ibishishwa bisanzwe.
8.Bikoreshwa nkibishishwa mubikorwa bya resin na plastike.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Bika ku bushyuhe butarenze 32 ° C n'ubushuhe bugereranije butarenga 80%.
4.Komeza ikintu gifunze.
5.Bigomba kubikwa bitandukanye nibyuma bya alkali hamwe nimiti iribwa, kandi ntibigomba na rimwe kuvangwa.
6.Yahawe ubwoko bukwiye nubwinshi bwibikoresho byo kurwanya umuriro.
7.Ahantu ho kubika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
