Ban told reporters he may propose the zones to the UN Security Council if UN inspectors confirm the chemical weapons use in an attempt to overcome the 15-nation council's "embarrassing paralysis" over the two and half years of conflict in Syria.
"I'm considering urging the Security Council to demand the immediate transfer of Syria's chemical weapons and chemical precursor stocks to places inside Syria where they can be safely stored and destroyed."
"And I urge again [that] Syria should become party to the OPCW [Organisation for the Prohibition of Chemical Weapons]," Ban told reporters in his first interaction on his return from St Petersburg, Russia where he had gone for the G-20 Summit.
The UN head said "I have already been considering certain proposals that I could make to the Security Council when I present the investigation team's report. For a number of days already, I have been considering our proposals in particular."

He said it would be proper for Syria to hand over control of its stock pile of chemical weapons to the international community.
"First and foremost, Syria must agree positively to this," he said.
Ban said the UN Security Council needs to give a united response and act if the inspectors report concluded that chemical weapons was used in Syria.
Noting that the two and half years of conflict in Syria have produced only "embarrassing paralysis" in the Security Council, Ban said that if the UN inspectors' report confirm the use of chemical weapons, this would surely be something around which the Security Council could unite in response.
