It's the busiest night of the year for fire brigades around the island and indeed the world - and that includes Dublin.
Dublin Fire Brigade had already responded to plenty of calls about bonfires, firework accidents and other dangerous incidents as people prepared to celebrate both the Bank Holiday weekend and Halloween.
As we moved into Monday night, the grim weather warning in place from Met Eireann didn't seem to dampen anyone's spirits.
Some took it too far though, as DFB had to respond to calls after a bonfire was lit in the middle of a road in Drimnagh
A DFB spokesperson said: "Lissadel Road in Drimnagh is temporarily blocked as firefighters extinguish a bonfire in the middle of the road. We hope to be clear soon."
Dublin City Council have also chimed in with their tips for what to do if you're heading along to a celebration on Monday evening.
In a handy guide on their website, they say:
- Bonfires are illegal, however, we have to be realistic. It is Halloween after all.
- Only attend organised events, this way you can be confident that the bonfire will be well built and not contain anything nasty.
- Over Halloween, and especially on the 31st, we will receive hundreds of 999/112 calls to report bonfires. This is because someone has a genuine concern.
- Bonfires can contain some nasty material such as car tyres, gas cylinders, aerosol cans, oils, plastics and household rubbish. The smoke from these types of fires is extremely toxic. The smoke can cause complications with people already suffering from breathing problems.
- Don’t get too close to a bonfire. If you feel the heat from a fire, then you are too close. Clothes or costumes are at risk of catching fire. Remember STOP, DROP & ROLL.
- Bonfires by their nature are destructive and bonfires built too high will collapse. Don’t be the one that it falls on. Stand well clear.
- Grass burned by bonfires will contain sharp and nasty debris for younger children or animals to injure themselves on. The grass will take over a year to recover.
- Don’t try to run through or jump over a bonfire. You’ll fall and give yourself serious irreversible injuries. Don’t give in to peer pressure.
- Don’t consume alcohol or other intoxicant around a bonfire.
