Ikibaho cya PVC gifitemo inyungu nyinshi, kandi gifatwa nkibishoboka cyane "gusimbuza ibikoresho gakondo byibiti" mumahanga.Imikorere yibicuruzwa nayo iratandukanye ukurikije ahantu hatandukanye hasabwa.Kurugero, "guteza imbere urugo PVC" byita cyane kubikorwa byumutekano no kurengera ibidukikije, gukora neza no gukora ibidukikije bidasanzwe, mugihe "ubuyobozi bwa PVC bwubucuruzi" bwita cyane kuramba, imikorere yubukungu, gukora isuku no kubungabunga.Hano haribintu bitatu byunvikana muburyo abantu basobanukiwe nibibaho bya PVC:
1. Kurinda umuriro ntabwo "bidashya";
Abantu bamwe bakeneye gukoresha itara kugirango batwike ikibaho cya PVC kugirango barebe niba gishobora gutwikwa.Uku ni ukutumvikana.Leta isaba ko igipimo cyumuriro cyibibaho bya PVC cyujuje ubuziranenge bwa Bf1-t0.Ukurikije igipimo cy’igihugu, ibikoresho bidashya bishobora gushyirwa mu rwego rwa A, nk'amabuye, amabati, n'ibindi. Ibikoresho bya tekinike yo mu rwego rwa Bf1-t0 flame retardant ni umupira w'ipamba ufite diameter ya mm 10, winjijwe muri alcool, ugashyirwa hasi ya PVC kugirango utwike bisanzwe.Umupira wipamba umaze gutwikwa, bapima diameter yumurambararo wa PVC watwitse, niba munsi ya 50mm aribwo Bf1-t0 flame retardant.
2. Kutangiza ibidukikije ntabwo bishingiye ku "kunuka";
Ibikoresho bya PVC ubwabyo ntabwo birimo fordehide, kandi ntabwo byemewe gukoresha fordehide mugikorwa cyo gukora hasi ya PVC.Ibibaho bimwe bya PVC byateye imbere bizakoresha calcium nshya ya karubone.Bizatera ingaruka mbi kumubiri wabantu utarinze gutuma abantu bumva bamerewe nabi.Bizatatana nyuma yo guhumeka mugihe runaka.
3. "Kurwanya Abrasion" ntabwo "bidashushanyijeho igikoresho gityaye";
Igihe abantu bamwe babazaga ubuzima bwa serivisi no kurwanya abrasion ya PVC ifuro, bafashe ibikoresho bikarishye nkicyuma cyangwa urufunguzo hanyuma bashushanya hejuru yubutaka bwa PVC.Niba hari ibishushanyo, batekereza ko bitarwanya abrasion.Mubyukuri, ikizamini cyigihugu cyo kurwanya abrasion yo hasi ya PVC ntabwo gishushanyije hejuru gusa nigikoresho gityaye, ahubwo kigenwa byumwihariko nikigo cyigihugu gishinzwe ibizamini.
