Hais txog tej nkev uas tsis zoo, kev faib tawm, IIB, thiab IIC denote txawv hom roj: IIA corresponds rau propane, IIB rau ethylene, thiab IIC rau hydrogen. Qauv xws li Exd IIA, Exd IIB, thiab Exd IIC yog suitable rau roj hazardous Zones 1 Thiab 2. Conversely, Ib qho khoom NL IIC yog txwv kom peb nyob tsam 2 Xwb.
