Holy smoke! It could be responsible (6)
I believe the answer is:
censer
This clue might be a double definition.
'holy smoke' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'it could be responsible' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for censer that I've seen before include "Incense burner" , "may be used in church" , "Thurible" , "Church burner" , "Container in which incense is burned" .)
