Hawaii Revised Statutes Division 4. Courts and Judicial Proceedings § 663-1.55

Any volunteer firefighter who in good faith renders firefighting services shall not be liable for any civil damages resulting from the person's acts or omissions occurring during the course of firefighting, except for such damages as may result from the person's gross negligence, or wanton acts or omissions.

For purposes of this section, volunteer firefighter means any person who trains as a volunteer firefighter and who, of the person's own free will, provides firefighting services in a fire emergency without remuneration or expectation of remuneration.

For purposes of this section, good faith includes, but is not limited to, a reasonable opinion that the immediacy of a fire is such that the rendering of firefighting service should not be postponed.
