Ukukhethwa Kwezisetshenziswa Zokugeza Amehlo

Ukukhethwa kwezinto zokusebenza kufanele kusekelwe phezu kwengozi.Cabangela inani labantu, imvamisa
yemisebenzi, uhlobo lwemisebenzi, izinhlayiya, namakhemikhali asetshenziswayo.Ngenjwayelo:

1. Usayizi ogcweleamashawa kanye neziteshi zokugeza amehlokufanele isetshenziswe ezindaweni zokusebenza lapho kwenziwa imisebenzi yansuku zonke ekhiqiza izinhlayiya noma kusetshenziswa amakhemikhali ayingozi kakhulu (okungukuthi amanani amakhulu namakhemikhali ayingozi agxilile).
2. Ukufakwa kwepayipi lokumanzisa elinezinhloso ezimbili kanye nokufakwa kokugeza amehlo kufanele kusetshenziswe ezindaweni eziyingozi ngokusesilinganisweni lapho kwenziwa imisebenzi yansuku zonke noma engajwayelekile (okungukuthi, amanani amancane nezisombululo ezincibilikayo noma amakhemikhali angenabungozi kangako).
3. Izinto zokugeza amehlo ezifakwe ngompompi kanye namapayipi okumanzisa kufanele kusetshenziswe ezindaweni zokusebenza ezinobungozi obuncane kanye nemisebenzi eyenzeka njalo (okungukuthi amanani amancane noma amakhemikhali ayingozi encane).
4. Amapayipi okumanzisa umlomo wombhobho owodwa ahloselwe ukwengeza izindawo zokugeza amehlo neshawa ezikhona futhi azithathwa njengezokuthatha indawo esikhundleni sezinto ezifanele zokugeza amehlo nomzimba.
5. Iziteshi zokugeza amehlo ze-gravity noma ibhodlela le-squirt kufanele zicatshangelwe kuphela ngomsebenzi wasensimini noma ukufakwa kwesikhashana lapho zizoshintshwa khona amapayipi amanzi.Izixazululo zokugeza amehlo kufanele zishintshwe ngokuvumelana nezincomo zomenzi.
