Emergency services across the country are urging parents and guardians to adhere to safety advice this Halloween.
Tomorrow night is traditionally one of the busiest times of the year for fire and ambulance services, with burns and traumas to limbs from fireworks, the most reported injuries.
Nearly 300 ambulance calls were received by emergency services on Halloween night alone last year.
Dublin Fire Brigade said it attended more than 600 call outs in a 24-hour period.
To ensure a safe and fun Halloween, the National Ambulance Service is urging parents and guardians to keep themselves and children visible to motorists when out trick or treating and to stay together in groups.
To prevent trips and falls, children's costumes should also be checked to make sure they are not too long or have too much loose fabric.
If attending bonfires, children should always be accompanied by an adult and never stand too close to the flames.
Although Halloween is tomorrow night, already the emergency services say they have been called to tend to bonfires.
Last night three units of Dublin Fire brigade attended a fire at Basin Street flats in Dublin, which affected the Luas Red line for a time.
A spokesperson for Dublin Fire Brigade has said, although bonfires are illegal they will only extinguish those that pose a risk to people and property.
They have also asked that members of the public allow the fire brigade to carry out their jobs unhindered.
