Around 500 staff from Dublin Fire Brigade, waste management services, parks, housing and local area offices are involved in this year's Halloween operation to ensure people celebrate the festivities safely.

The overall cost to the council is about €750,000, including fire call outs, events, damage to parks and stockpiling operations.

Dublin Fire Brigade says it had more than 700 calls last year, and seized more than 1,000 tonnes of material intended for illegal bonfires.

Plastic surgeon Odhran Shelley of the National Burns Unit at St James's Hospital said the unit sees injuries from fireworks and bonfires every year.

In Dublin there are events being held in areas including Finglas, Ballymun, Ballyfermot, Inchicore and Darndale.

Local authorities say there are lots of festivals and community events organised around the country.

Children are being urged to stay safe and only attend supervised bonfires.
