People are being urged to report stockpiles of bonfire material in their local areas, as Dublin Fire Brigade warns of the dangers of unregulated bonfires in the run up to Halloween.
Assistant Chief Fire Officer Greg O'Dwyer said crews are removing stockpiles that they find.
Dublin Fire Brigade said all bonfires are prohibited.
Speaking on RTÉ's Morning Ireland, he said unregulated bonfires are extremely dangerous and can contain materials that can explode and cause serious injuries.
"There could anything in there from gas cylinders, aerosols, anything like that, and fireworks themselves being put on the bonfires. And they ... come out of the bonfire like missiles in any direction, uncontrollable and can injure people".
He also said such fires cause environmental damage "on a green field pitch or whatever", with some areas taking a year or more to recover.
He urged people to attend organised events which are listed on local authority websites.
"They're safe organised events, some with legal fireworks and so on. And there's great activities there for kids, an awful lot more fun than standing around a bonfire. The message we're trying to get out there is, bonfires are, you know, obviously they're illegal, but they're extremely dangerous."
Dublin Fire Brigade has issued the following advice:
If you find yourself near an unauthorised bonfire or fireworks display:
Never use fireworks under the influence of alcohol or drugs
Keep children at a safe distance.
Stay well back from fires and fireworks.
Never return to a lit firework - wait 20 minutes and soak it in water.
Never throw fireworks.
