Desain flameproof biasane duwe threading tinimbang komponen sing bisa dilebokake. Piranti kelas C nyedhiyakake lumahing flameproof sing luwih dawa lan celah bledosan sing luwih sempit. hidrogen, asetilena, lan karbon disulfida mbutuhake panggunaan kelas IIC, whereas other substances are adequately served by IIB class.
