The HSE and the Road Safety Authority (RSA) have warned parents and young people to be extra vigilant when taking part in Halloween activities this evening.
The Halloween period is one of the busiest times of the year for emergency services and every year children end up hurt or scarred for life as a result of not taking simple safety precautions, the HSE said.
Dr Patricia Eadie, clinical director of the burns unit at St James's Hospital and consultant plastic surgeon said: "Fireworks are always a cause for concern. Every year we have to treat children who have significant injuries caused by varying types of Halloween activities.
She said: “There have already been several children who have been admitted to hospital in the run up to this busy period."
Although most fireworks, except those used licensed displays, are illegal here, many are still on sale in markets or from street vendors.
The HSE said the majority of these fireworks and bangers on sale are sub-standard and liable to cause injury.
It also warned that bonfires often contain highly combustible materials that can cause respiratory problems and burns.
Parents were also advised to check their children’s collections, as nuts and boiled sweets can cause obstruction and choking.
The RSA today also urged motorists to take extra care when driving home and to watch out for children out trick or treating.
"With Halloween falling on a work day, and with children on mid-term break from school, more children than usual are likely to be on the streets and roads in the early evening, dressed in dark costumes or wearing masks, making it difficult for them to see and be seen," the RSA said.
The Dublin Society for the Prevention of Cruelty to Animals has also warned pet owners that Halloween a very distressing time for animals.
The society advised people to keep their pets quiet place and away from exit doors. “Putting a radio or television on in the room can also be effective,” it said.
