(1) Any person who gratuitously and in good faith renders emergency care or treatment by the use of or provision of an automated external defibrillator without objection of the person to whom care or treatment is rendered;

(2) The owner or operator of any premises or conveyance who installs or provides automated external defibrillator equipment in or on such premises or conveyance;

(4) Any person who provides training in the use of automated external defibrillator equipment as required by subparagraph (b)(1)(A) of Code Section 31-11-53.2, whether compensated or not. This Code section is not applicable to any training or instructions provided by the manufacturer of the automated external defibrillator or to any claim for failure to warn on the part of the manufacturer.

(b) Nothing in this Code section shall be construed so as to provide immunity to the manufacturer of any automated external defibrillator or off-premises automated external defibrillator maintenance or service providers, nor shall it relieve the manufacturer from any claim for product liability or failure to warn.
