Notwithstanding any inconsistent provision of any general, special or local law, any certified athletic trainer who voluntarily and without the expectation of monetary compensation renders first aid or emergency treatment at the scene of an accident or other emergency, outside a hospital, doctor’s office or any other place having proper and necessary athletic training equipment, to a person who is unconscious, ill or injured, shall not be liable for damages for injuries alleged to have been sustained by such person or for damages for the death of such person alleged to have occurred by reason of an act or omission in the rendering of such first aid or emergency treatment unless it is established that such injuries were or such death was caused by gross negligence on the part of such athletic trainer. Nothing in this section shall be deemed or construed to relieve a certified athletic trainer from liability for damages for injuries or death caused by an act or omission on the part of an athletic trainer while rendering professional services in the normal and ordinary course of his or her practice.
