Iimpawu zeipleyiti yentsimbi isakhiwo sokudubula umatshini wokuqhumisa:
2. Isiphumo sokususa umhlwa silungile, kwaye izinga lokususa i-rust lifikelela ku-SA2.5 okanye ngaphezulu.
3. Ukuvelisa uburhabaxa obufanayo kunye nokwandisa ukunamathela kwepeyinti.
4. Ukusebenza kakuhle komsebenzi kuphezulu, insimbi ifakwe kwi-roller conveyor, kunye nokusebenza komgca wendibano kunokucoca ngesantya se-1 ukuya kwi-3 yeemitha ngomzuzu. Ngokuqinisekileyo, isantya esiphezulu sokucoca sinokuyilwa kwaye silungiselelwe ngokwendawo yomsebenzisi.
5. Igcina abasebenzi kunye nezinto eziphathekayo kwaye inokusebenza xa ixhunyiwe kumbane.
6. Isixhobo sixhotyiswe ngomqokeleli wothuli, ukukhuselwa kwendalo kunye nomsebenzi ongenabungcoliseko, kwaye ukukhutshwa komoya kufikelela kumgangatho wesizwe wokukhuselwa kwendalo. Sisixhobo sokukhusela indalo esingqongileyo.
