Mumakamuri akachena emicroelectronics uye kugadzirwa kwemishonga, zvakasiyana-siyana acidic uye alkaline zvinhu, organic solvents, general magasi, uye magasi anokosha anowanzoshandiswa kana kugadzirwa mukugadzira;mune allergenic zvinodhaka, mamwe steroid Mukugadzirwa kwezvinodhaka zvinodhaka, zvinonyanya kushanda uye zvine chepfu zvinodhaka, zvinoenderana nezvinhu zvinokuvadza zvichabudiswa kana kudonhedzwa muimba yakachena.Naizvozvo, michina yekugadzira michina kana maitirwo anogona kubudisa zvakasiyana-siyana zvinokuvadza zvinhu, magasi kana guruva muimba yakachena yekugadzirwa kwezvinhu zviri pamusoro Gadzira mudziyo wepamhepo wepopotera kana yakazara kamuri yekupopota mudziyo.Zvinoenderana nerudzi rwemarara gasi anoburitswa panguva yekugadzira, iyo exhaust mudziyo (system) inogona kukamurwa kuita anotevera marudzi.
