Isicima-mlilo sokuqala sasinelungelo elilodwa lomenzi wekhemisti u-Ambrose Godfrey ngo-1723. Ukususela ngoko, iindidi ezininzi zokucima umlilo ziye zaqanjwa, zatshintshwa zaza zaphuhliswa.
Kodwa into enye ihlala ifana nokuba ithini na ixesha - izinto ezine kufuneka zibekho kwi-aumlilo ukuba ubekho. Ezi zinto ziquka ioksijini, ubushushu, amafutha kunye nokusabela kweekhemikhali. Xa ususa enye yezinto ezine kwi “unxantathu womlilo,” umlilo unokucinywa.
Nangona kunjalo, ukuze ucime ngempumelelo umlilo, kufuneka usebenzise iisicima-mlilo esichanekileyo.

AMANQAKU ENXULUMENEYO
Kutheni izixhobo zokucima umlilo, ii-ambulensi zifuna izicima-mlilo eziphathwayo
Izifundo ekusebenziseni isicima-mlilo
Indlela yokuthenga izixhobo zokucima umlilo
Ezona ntlobo zixhaphakileyo zezicimi-mlilo ezisetyenziswa kwiintlobo ezahlukeneyo zezibaso zomlilo zezi:
- Isicimi-mlilo samanzi:Izicima-mlilo zamanzi zicima imililo ngokususa ubushushu obukunxantathu womlilo. Zisetyenziselwa imililo yodidi A kuphela.
- Isixhobo sokucima umlilo esinekhemikhali eyomileyo:Izitshizi zokucima imichiza eyomileyo ziwucima umlilo ngokuphazamisana nekhemikhali kanxantathu womlilo. Zisebenza kakhulu kwimililo yodidi A, B kunye no-C.
- I-CO2 yokucima umlilo:Izicima-mlilo zekharbhon diokside zithatha inxalenye yeoksijini ekunxantathu womlilo. Baphinde basuse ubushushu ngokukhupha okubandayo. Zingasetyenziswa kwimililo yodidi B noC.
Kwaye ngenxa yokuba yonke imililo ibaswa ngokwahlukileyo, kukho iintlobo ngeentlobo zezinto zokucima umlilo ezisekelwe kuhlobo lomlilo. Ezinye izicima-mlilo zinokusetyenziswa kwiindidi ezingaphezu kolunye lomlilo, ngoxa ezinye zilumkisa nxamnye nokusetyenziswa kwezicimi-mlilo zodidi oluthile.
Nalu ulwahlulo lwezicimi-mlilo ezihlelwe ngokodidi:
| Izicima-mlilo ezihlelwe ngokodidi: | Izinto zokucima umlilo zisetyenziselwa ntoni: |
| Udidi A isicima-mlilo | Ezi zicimi-mlilo zisetyenziselwa imililo ebandakanya izinto eziqhelekileyo ezinokutsha, ezifana neenkuni, iphepha, amalaphu, inkunkuma neeplastiki. |
| Isicima-mlilo seClass B | Ezi zicimi-mlilo zisetyenziselwa imililo equka ulwelo olunokutsha, njengegrisi, ipetroli neoli. |
| Isitshizi somlilo seClass C | Ezi zicimi-mlilo zisetyenziselwa imililo ebandakanya izixhobo zombane, ezinjengeenjini, iitransformer kunye nezixhobo zombane. |
| Class D isicima-mlilo | Ezi zicimi-mlilo zisetyenziselwa imililo ebandakanya iintsimbi ezinokutsha, ezifana nepotassium, isodiyam, ialuminiyam kunye nemagnesium. |
| Udidi K lokucima umlilo | Ezi zicimi-mlilo zisetyenziselwa imililo equka ioli yokupheka negrisi, njengamafutha ezilwanyana nawemifuno. |
Kubalulekile ukukhumbula ukuba umlilo ngamnye ufuna isicimi-mlilo esahlukileyo ngokweemeko.
Kwaye ukuba uza kusebenzisa isicima-mlilo, khumbula nje i-PASS: tsala isikhonkwane, ujongise umlomo okanye umbhobho kwisiseko somlilo, cofa inqanaba lokusebenza ukukhupha isixhobo sokucima kwaye utshayela umbhobho okanye umbhobho ukusuka kwelinye icala ukuya kwelinye. ude ucime umlilo.
