A duly licensed physician or a registered nurse or a person acting under his direction, or any other person who renders emergency care at the scene of an emergency occurrence, may use reasonable physical force for the purpose of administering a recognized and lawful form of treatment which is reasonably adapted to promoting the physical or mental health of the patient if:

(a) The treatment is administered with the consent of the patient or, if the patient is a minor or an incompetent person, with the consent of his parent, guardian or other person entrusted with his care and supervision except as otherwise provided by law; or

(b) The treatment is administered in an emergency when the person administering such treatment reasonably believes that no one competent to consent can be consulted and that a reasonable person, wishing to safeguard the welfare of the patient, would consent.
