The majority of Halloween fireworks are being given to children by their parents, an Assistant Chief Fire Officer with Dublin Fire Brigade has said.
Greg O'Dywer was speaking as the fire service received 244 fire calls, and 385 emergency medical calls, in a 24-hour period across Halloween.
Of the 244 calls, 190 of them were bonfire-related.
Mr O'Dywer told Newstalk Breakfast the numbers were quite similar to last year's.
"We've seen a steady decrease in Halloween activity over the last number of years, mostly down to the local authority organised events where people can go and have a fun and safe evening," he said.
"Also local authorities taking away stockpiles of bonfire materials, reducing the number of fires and making those that are there smaller.
"Of course, the weather played its part last night."
Mr O'Dywer said the fire brigade's busiest time was after-dark.
"Between the hours of say 4:30pm when it got dark till about 7pm we'd over 100 calls," he said.
"That was the busiest period.
"[There were] a lot of bonfires, most of them small in areas that weren't dangerous so we could just monitor them and leave those.
"Some of the bigger ones and more dangerous ones that were closer to buildings or telegraph poles, they had to be extinguished.
"Then we had a few firework-related injuries - not too many thank God - two children's hands were injured."
Mr O'Dywer said most of the fireworks in circulation in Ireland are given to children by their parents.
"It was obvious the increase in fireworks, it really was very noticeable last night," he said.
"What we're kind of despairing at is, most of the kid’s fireworks are coming from parents.
"Parents are going across the [border] or whatever and getting these fireworks.
"People are having these impromptu firework displays in their back gardens, or maybe for their street or even for their estate.
"They're really riding their luck," he added.
