Calls have been made to ban the use of electronic cigarettes in council-owned buildings and vehicles in Caerphilly.
This comes after the Welsh government recently announced plans to ban e-cigarettes in public places in response to concerns they normalise smoking.
If agreed, the move would see electronic cigarettes treated in the same way as conventional cigarettes.
Caerphilly council say the proposal was put forward "because of a number of incidents with employees wishing to use electronic cigarettes within council premises".
Caerphilly council also said that it had received complaints of taxi drivers smoking e-cigarettes in vehicles - a problem which has also been reported in Swansea.
Earlier this month, talking about a Wales-wide ban, Health Minister Mark Drakeford said: "I have concerns about the impact of e-cigarettes on the enforcement of Wales's smoking ban. That's why we are proposing restricting their use in enclosed public places.
"I am also concerned that their use in enclosed public places could normalise smoking behaviour."
The proposal must be agreed by a Caerphilly council cabinet before its introduction.
