Iipayipi ezifakwe intsimbi engagqwali zisetyenziswa kakhulu kubunjineli bokuhombisa imimandla yasezidolophini; kwicandelo lemizi-mveliso elula, amayeza, ukwenza iphepha, unyango lwelindle, unikezelo lwamanzi, oomatshini, njl.njl., kukwakho nenxalenye enkulu; kwicandelo leekhemikhali, izichumisi, iikhemikhali kunye nezinye izimboni, iinkcukacha ngokubanzi yi-Φ159mm. Iipayipi ezithwala uxinzelelo oluphakathi noluphantsi ngasentla; isixhobo sokuvala iimoto sisebenzisa iipayipi ezifakwe intsimbi engagqwali.

Iipayipi ezingenamthungo zentsimbi engagqwaliyo zisetyenziswa kakhulu kwi "khemikhali ezintathu" (iikhemikhali, isichumisi, iifayibha zeekhemikhali), ipetroliyam, iibhoyila zamandla ombane, oomatshini, inqwelo moya, imboni yenyukliya, imboni yokhuselo lwesizwe kunye neminye imimandla.
