A new position is being added to the team of 70 physicians, nurses, paramedics and first responders will be volunteering at the AC/DC concert.

A sexual assault nurse examiner will be on site to remind concert goers that consent doesn't mix with alcohol.

Trena Brown is managing the Magnetic Hill concert site medical team and says the new position was added as a proactive move.

"Our goal is to keep everybody safe, and there's always been a little bit of lingering concern that certainly some of the behaviours that go with the hill increase your risk for certain things. You can't consent under the influence of anything so there's always been a little bit of concern there."

To the best of Brown's knowledge there's never been a reported incident of sexual assault during a Magnetic HIll concert before, and she hopes to keep it that way.

Most of the injuries the team tends to are minor.

"Sometimes bumps, bruises, we're lucky that the weather is decent. We had a very slippery experience with the Nickleback concert and it was wet, wet."

"The weather looks good, so we should have fewer of those slip/slide fracture events."

With fair weather come other concerns, like dehydration, sunburns and heat exhaustion.

"We're encouraging people to drink lots of water, dress in layers, wear some sun screen," said Brown.

"My best advice is to plan your day. It is the Maritimes, it might be 28 [Celcius] in the middle of the afternoon, but it's going to be 14 before you know it."

The medical team will be easy to identify with their vest and hats with a big red cross. The team will be stationed under large white helium balloons, but can also move through the crowd via a small all-terrain vehicle.

The concert promoter expects about 40,000 people to attend Saturday's concert.
