When responding to a 911 emergency call received at a public safety answering point, public safety officers of public safety agencies may use reasonable and necessary means to enter any dwelling, dwelling unit, or other structure without the express permission of the owner when:
(1) The dwelling or structure is believed to be the geographical location of the telephone used to place the 911 emergency call as determined by an automatic locator or number identifier; and
(2) Only after reasonable efforts have been made to arouse and alert any inhabitants or occupants of their presence and the officers have reason to believe that circumstances exist which pose a clear threat to the health of any person or they have reason to believe there may be a person in need of emergency medical attention present in the dwelling or structure who is unable to respond to their efforts.
