I-1, Ukulungiswa kwexesha elinye.Izikhonkwane ze-Twister zinokulungisa iimveliso zeplastiki kunye nezikhonkwane ze-twister kanye, ukuphepha ilahleko ebangelwa ukulungiswa okungahambi kakuhle, ukutsalwa ngokuphindaphindiweyo kunye nokubethelela ngaphakathi.
I-2, Sisebenzisa izinto ze-carbon steel ukwenza, umphezulu ufakwe i-galvanised, i-corrosion resistant, inokwandisa ukusetyenziswa kwexesha.
3, Ngokusebenza kweendleko eziphezulu, izikhonkwane ze-twister ezithengiswayo ngoku emarikeni luhlobo lwesikhonkwane esisetyenziselwa ukulungisa iithayile zeasbestos, imarike igcwele kakuhle, ke ngoko, izikhonkwane ezijijekileyo lolona khetho lubalaseleyo lokulungisa iplastiki kunye neemveliso zeasbestos. .
Zonke iimveliso eziveliswe yinkampani ziye zahlolwa ngokungqongqo lisebe lolawulo lomgangatho kwaye zikumgangatho obalaseleyo. Uvavanyo oluvunyiweyo oluvunyiweyo lweemveliso, ezithengisa kwihlabathi liphela ukufumana indumiso yabasebenzisi abaninzi.
