That was the advice issued yesterday by the St John Ambulance Brigade of Ireland, which has drawn up a 17-point Ultimate Survival Guide for music-lovers.
The brigade’s advice comes as fans flock to events like the Rolling Stones at Slane Castle in Co Meath, the Electric Picnic at Stradbally, Co Laois, and concerts at Dublin’s Marlay Park.
With no sign of a break from summer’s dismal weather, the organisation is also urging fans to carry a black bin-liner with them in case they need a makeshift raincoat.
The St John guide also advises revellers to drink enough water to avoid dehydration, protect themselves from sunstroke and charge their mobile phone up before leaving home.
“Much of our Ultimate Survival Guide is common sense but we have found that common sense often goes out the window while safety takes a back seat on big days out,” said brigade assistant commissioner Patrick K Plunkett.
“We never cease to be surprised by the incidents that occur simply because people forget to consider the basics when attending public events.”
The St John Ambulance sends volunteers and its fleet of vehicles to a host of summer events with specialists including first aiders, paramedics, and doctors.
Among the advice is a warning not to accept a drink that has not been handed to them personally by a bar tender.
Other tips includes bringing a pack of baby wipes for hygiene, remembering to bring sun cream and enough money to buy water.
Concert-goers, both male and female, are also urged to beware of accepting lifts from strangers.
