Isicisha-mlilo sokuqala sanikwa ilungelo lobunikazi ngusokhemisi u-Ambrose Godfrey ngo-1723. Kusukela ngaleso sikhathi, izinhlobo eziningi zezicisha-mlilo ziye zasungulwa, zashintshwa futhi zathuthukiswa.
Kodwa into eyodwa ihlala ifana kungakhathaliseki ukuthi inkathi injani — izinto ezine kumele zibe khonaumlilo uzoba khonaLezi zinto zifaka umoya-mpilo, ukushisa, uphethiloli kanye nokusabela kwamakhemikhali. Uma ususa enye yezinto ezine ku-“unxantathu womlilo,” umlilo ungacinywa-ke.
Nokho, ukuze ucime umlilo ngempumelelo, kufanele usebenziseisicisha-mlilo esifanele.

IZIHLOKO EZIHLOBENE
Kungani imishini yokucima umlilo, ama-ambulensi edinga izicisha-mlilo eziphathekayo
Izifundo zokusebenzisa izicisha-mlilo
Indlela yokuthenga izicisha-mlilo
Izinhlobo ezivame kakhulu zezicisha-mlilo ezisetshenziswa ezinhlotsheni ezahlukene zamafutha omlilo yilezi:
- Isicisha-mlilo samanzi:Izicisha-mlilo zamanzi zicima imililo ngokususa isici sokushisa sonxantathu womlilo. Zisetshenziselwa imililo yeSigaba A kuphela.
- Isicisha-mlilo samakhemikhali omile:Izicisha-mlilo zamakhemikhali ezomile zicima umlilo ngokuphazamisa ukusabela kwamakhemikhali konxantathu womlilo. Zisebenza kahle kakhulu emililweni yeSigaba A, B kanye no-C.
- Isicisha-mlilo se-CO2:Izicisha-mlilo ze-carbon dioxide zisusa i-oxygen element yonxantathu womlilo. Zisusa nokushisa ngokukhipha okubandayo. Zingasetshenziswa emililweni ye-Class B ne-C.
Futhi ngenxa yokuthi yonke imililo ivuselelwa ngendlela ehlukile, kunezinhlobo ezahlukene zezicisha-mlilo ngokusekelwe ohlotsheni lomlilo. Ezinye izicisha-mlilo zingasetshenziswa ezinhlotsheni ezingaphezu kweyodwa zomlilo, kanti ezinye zixwayisa ngokusetshenziswa kwezicisha-mlilo zeklasi ethile.
Nasi uhlu lwezicisha-mlilo ezihlukaniswe ngohlobo lwazo:
| Izicisha-mlilo ezihlukaniswe ngohlobo: | Izinto ezisetshenziswayo zokucima umlilo: |
| Isicisha-mlilo sekilasi A | Lezi zicisha-mlilo zisetshenziselwa imililo ehlanganisa izinto ezivamile ezivuthayo, njengokhuni, iphepha, indwangu, udoti kanye nepulasitiki. |
| Isicisha-mlilo sekilasi B | Lezi zicisha-mlilo zisetshenziselwa imililo equkethe uketshezi oluvuthayo, njengamafutha, uphethiloli kanye namafutha. |
| Isicisha-mlilo sekilasi C | Lezi zicisha-mlilo zisetshenziselwa imililo ehlanganisa imishini kagesi, njengezinjini, ama-transformer kanye nezinto zikagesi. |
| Isicisha-mlilo sekilasi D | Lezi zicisha-mlilo zisetshenziselwa imililo ehlanganisa izinsimbi ezivuthayo, njenge-potassium, i-sodium, i-aluminium kanye ne-magnesium. |
| Isicisha-mlilo sekilasi K | Lezi zicisha-mlilo zisetshenziselwa imililo ehlanganisa amafutha okupheka namafutha, njengamafutha ezilwane nemifino. |
Kubalulekile ukukhumbula ukuthi umlilo ngamunye udinga isicisha-mlilo esihlukile kuye ngezimo.
Futhi uma uzosebenzisa isicisha-mlilo, khumbula nje UKUDLULA: donsa iphini, uqondise umlomo noma ipayipi phansi komlilo, cindezela izinga lokusebenza ukuze ukhiphe into yokucisha bese ushanela umlomo noma ipayipi kusukela kolunye uhlangothi kuya kolunye kuze kube yilapho umlilo ucima.
