Uyilo lwe-flameproof lubonisa ukuthunga endaweni yezinto ezifakelwayo. Izixhobo zodidi C zibonelela ngemigangatho emide engatshiyo kunye nezikhewu ezicuthekileyo ezidubulayo. Ihydrogen, iacetylene, kunye ne-carbon disulfide ifuna ukusetyenziswa kweklasi ye-IIC, whereas other substances are adequately served by IIB class.
