Umehluko phakathi Kokubiyelwa Kobufakazi Bokuqhuma kanye Nendlela Yokuvikela Ngaphakathi

Izindawo eziyingozi njengezindawo zokuhluza uwoyela, izitolo zikapende nezitshalo zamakhemikhali zinamandla amakhulu okuqhuma. Endaweni enjalo, inhlansi encane yanele ukubangela ukuthungela.

Njengoba lokhu kuqhuma okuyingozi kungase kwenzeke ngisho nobuchwepheshe obukhethekile obukhona, kubaluleke kakhulu ukuthi ngesikhathi sokuklanywa kwefektri, izinto zikagesi akufanele zibekwe kulezi zindawo eziyingozi.

Sengikushilo lokho, kubalulekile ukuqaphela ukuthi lezi zindawo zidinga amathuluzi akhethekile afakwe ukuze kuvikelwe abasebenzi nabanye abantu abasendaweni ngokumelene nanoma yiziphi iziqhumane. Le mishini eyenziwe ngokukhethekile iwela ngaphansi kwezigaba ezimbili okuyilezi:

1. Okuphephile ngaphakathi

2. Ubufakazi bokuqhuma

I-Intrinsically Safe Technique

Le ndlela yenziwe ngendlela yokuthi uma kwenzeka kuba nephutha kumjikelezo kagesi, akukho ukuthungela noma ukuqhuma okungenzeka. Izintambo zenziwa ngendlela yokuthi ngaphansi kwesimo zingakwazi ukukhuphukela emazingeni okushisa aphezulu ngokwanele ukukhuthaza ukuthungela. Umthamo wamandla walolu cingo ulawulwa kusetshenziswa izithiyo zokuphepha zangaphakathi. Ibizwa nangokuthi indlela yokuvimbela.

Ezinye izimiso zayo yilezi:

· Ukufakwa kwayo kulula njengoba kusetshenziswa izinto ezijwayelekile nezilula ekwakhekeni kwayo.

· Izesekeli zishibhile

· Uma ukulinganisa noma ukulungiswa kuyadingeka, ugesi akudingeki unqanyulwe.

· Noma yibaphi abasebenzi abanekhono bangasinakekela.

· Indlela ayidingi izindlela zokufaka izintambo eziqondile.

Imikhawulo yendlela ephephile yangaphakathi:

· Isetshenziswa kangcono kuphela kumadivayisi asebenzisa amandla aphansi kakhulu ekusebenzeni kwawo.

· Ukusetshenziswa kwayo kukhawulelwe ezinhlelweni ezimbalwa kuphela njengoba imishini eminingi zisebenzisa amandla ombane aphezulu.

· Ayikwazi ukuqukatha noma yikuphi ukuqhuma noma ukumelana nezimo zemvelo ezinzima.

· Kulinganiselwe uhlobo izinzwa ukuthi angazisebenzisa.

I-Explosion Proof Technique:

Kuphinde kubizwe ngokuthi indlela yokuvimbela ukuqhuma. Iklanywe ngendlela yokuthi ingavumela ukuqhuma ukuba kwenzeke endaweni evalelwe. Lokhu kudinga ukuthi ukwakhiwa kwendawo ebiyelwe kwenziwe kusetshenziswa izinto ezisindayo njengensimbi noma i-aluminium enekhono lokuqukatha ukuqhuma. Yilona elisetshenziswa kakhulu ezinhlelweni eziningi ezidinga ukusetshenziswa kwamazinga aphezulu wamandla.

Izimiso zokuklama kwayo:

· Indawo ebiyelwe kufanele iqine.

· Kumele ikwazi ukumelana nokuqhuma.

· Ukuseviswa kwalawa madivaysi kwenziwa kuphela ngabasebenzi abaqeqeshiwe futhi kwenziwa ngamathuluzi afanele.

· Zisinda futhi ziningi.

· Izinsimbi ezisetshenziswa kakhulu i-aluminium nensimbi.

Imikhawulo yobuchwepheshe bobufakazi bokuqhuma:

· Izindleko zensimbi engagqwali noma i-aluminium esetshenziselwa ukwenza izivalo ziyabiza.

· Uma umkhathi unomswakama kakhulu, kungase kuphakame izinkinga phakathi kwezivalekile ngenxa yokujiya.

· Ngenxa yesisindo esinzima sezindawo ezivalekile, kungase kube nezinkinga ngesikhathi sokufakwa kohlelo.

· Ubuqotho bemishini yohlelo yibo obunquma izinga lokuphepha kwalolu hlelo. Uma ukuhlolwa kungenziwanga ngezikhathi ezibekiwe, ukuphepha kuba sengozini.

· Ukwenziwa kwanoma yiziphi izinguquko ohlelweni kunzima ukukufeza.

Izinto ezibalulekile okufanele uzicabangele lapho ukhetha ukuthi iyiphi indlela ozoyisebenzisela isitshalo sakho noma imboni:

· Inani lamandla asetshenziswa embonini. Uma iphezulu, khona-ke inketho yakho engcono kakhulu indlela yokuqinisekisa ukuqhuma, uma iphansi ungakhetha indlela yangaphakathi.

· Isabelomali sakho; uma uphoqelekile futhi ungakwazi ukukhokhela izesekeli ezibizayo ezisetshenziswa endleleni yobufakazi bokuqhuma, inketho yakho kungaba indlela yangaphakathi.

· Hlala uqinisekisa ukuthi umkhiqizo owusebenzisayo uqinisekisiwe ukuthi uzowusebenzisa endaweni osebenza kuyo ukuze ungazifaki ezinkingeni ngomthetho.
