Isicima-mlilo sokuqala sanikwa ilungelo lobunikazi yingcali yekhemisti u-Ambrose Godfrey ngo-1723. Ukususela ngoko, iintlobo ezininzi zezicima-mlilo ziye zaveliswa, zatshintshwa zaza zaphuhliswa.
Kodwa kukho into enye ehlala ifana nokuba lixesha lini na — izinto ezine kufuneka zibe khona kwixeshaumlilo uza kubakhoEzi zinto ziquka ioksijini, ubushushu, amafutha kunye nempendulo yamakhemikhali. Xa ususa enye yezinto ezine kwi "unxantathu womlilo,” umlilo ungacinywa emva koko.
Nangona kunjalo, ukuze ucime umlilo ngempumelelo, kufuneka usebenziseisicimi-mlilo esichanekileyo.

AMANQAKU AFANELEKILEYO
Kutheni izixhobo zokucima umlilo, ii-ambulensi zifuna izixhobo zokucima umlilo eziphathekayo
Izifundo zokusetyenziswa kwezicimi-mlilo
Indlela yokuthenga izicimi-mlilo
Iindidi eziqhelekileyo zezicima-mlilo ezisetyenziswa kwiintlobo ezahlukeneyo zezibaso zomlilo zezi:
- Isicima-mlilo samanzi:Izicima-mlilo zamanzi zicima imililo ngokususa ubushushu obukwinxantathu yomlilo. Zisetyenziselwa imililo yeKlasi A kuphela.
- Isicima-mlilo esomileyo sekhemikhali:Izicima-mlilo ezomileyo zicima umlilo ngokuphazamisa indlela esebenza ngayo ikhemikhali kunxantathu womlilo. Zisebenza kakhulu kwimililo yeClass A, B kunye neC.
- Isitshizi-mlilo se-CO2:Izicima-mlilo ze-carbon dioxide zisusa i-oxygen element ye-fire triangle. Zikwasusa ubushushu ngokukhupha okubandayo. Zingasetyenziswa kwimililo yeClass B kunye neC.
Kwaye ngenxa yokuba yonke imililo ivuthiswa ngokwahlukileyo, kukho iintlobo ngeentlobo zezicimi-mlilo ezisekelwe kuhlobo lomlilo. Ezinye izicimi-mlilo zingasetyenziswa kwiindidi ezahlukeneyo zomlilo, ngelixa ezinye zilumkisa ngokusetyenziswa kwezicimi-mlilo zeklasi ethile.
Nantsi inkcazo yezixhobo zokucima umlilo ezihlelwe ngokweentlobo zazo:
| Izicimi-mlilo zahlulwe ngohlobo lwazo: | Izinto ezisetyenziselwa izicima-mlilo: |
| Isitshizi-mlilo seKlasi A | Ezi zicima-mlilo zisetyenziselwa imililo equka izinto eziqhelekileyo ezivuthayo, ezifana neenkuni, iphepha, ilaphu, inkunkuma kunye neeplastiki. |
| Isicima-mlilo seKlasi B | Ezi zicima-mlilo zisetyenziselwa imililo equka ulwelo oluvuthayo, njengegrisi, ipetroli kunye neoyile. |
| Isitshizi-mlilo seKlasi C | Ezi zicima-mlilo zisetyenziselwa imililo equka izixhobo zombane, ezinje ngeemoto, iitransformer kunye nezixhobo. |
| Isicima-mlilo seKlasi D | Ezi zicima-mlilo zisetyenziselwa umlilo oquka iintsimbi ezitshayo, ezifana ne-potassium, i-sodium, i-aluminium kunye ne-magnesium. |
| Isitshizi-mlilo seKlasi K | Ezi zicima-mlilo zisetyenziselwa umlilo oquka iioyile zokupheka kunye neegrisi, ezifana namafutha ezilwanyana kunye nemifuno. |
Kubalulekile ukukhumbula ukuba umlilo ngamnye ufuna isicima-mlilo esahlukileyo ngokweemeko.
Kwaye ukuba uza kusebenzisa isicima-mlilo, khumbula nje UKUDLULA: tsala iphini, ujolise umlomo okanye ipayipi ezantsi komlilo, cima inqanaba lokusebenza ukuze ukhuphe isixhobo sokucima umlilo kwaye utshayele umlomo okanye ipayipi ukusuka kwelinye icala ukuya kwelinye ude umlilo ucime.
