No physician or other person who, in good faith, renders emergency care at the scene of an emergency is liable for harm resulting from an act or omission in providing such care unless the person's act or omission was meant to cause harm or is grossly negligent. Persons hired for such care, such as ambulance drivers, are not protected from liability arising from their operation of the vehicle (PA Stat. Tit. 42 Sec. 8331, Sec. 8332).
