CITY authorities are on the hunt for stockpiles of wood and rubber ahead of the Halloween weekend.
Dublin Fire Brigade and the City Council have warned that all bonfires are illegal as they launched a new 'Be Safe -- Be Seen' campaign.
So far this year the council has taken over 500 tonnes and will be running inspections and carrying out stockpiling raids over the coming days.
Lord Mayor Oisin Quinn said: "Bonfires and fireworks at Halloween are extremely dangerous and can cause a lot of injuries and damage.
"All bonfires are illegal and our message is: do not go to them and if you are aware of any material being stockpiled please report it to us in confidence."
The fire service responded to 639 call-outs between in just 16 hours last Halloween night.
Since 2009, the number of calls Dublin Fire Brigade receives has reduced by more than a quarter on Halloween Night.
As part of the latest awareness campaign Dublin Fire Brigade has sent a Halloween Safety Pack with leaflets and posters to all primary schools in Dublin advising children how to act responsibly and avoid danger over Halloween.
