Whakatauranga pahū:
Ko nga taputapu pahū me te tohu CT4 ka tohua hei Exd IIC T4. Ko nga taputapu pahū BT4 kua tohua hei Exd IIB T4, he iti ake te whakatauranga pahūtanga i te taputapu CT4.

Te Whakamahinga:
Kei a CT te whānuitanga whanui o te whakamahinga.
Te taiao hau:
CT is an explosion-proof rating for acetylene and hauwai taumata. If there are gases like acetylene or hydrogen in the environment, CT-rated explosion-proof equipment is required. BT-rated equipment is not suitable for acetylene environments and is only considered a moderate explosion-proof level.
