No school district, member of a school board, or school district employee shall be liable in a suit for damages as a result of any act or omission related to a pupil’s use of an inhaler if the provisions of N.H. Rev. Stat. § 200:46 have been met, unless the damages were caused by willful or wanton conduct or disregard of the criteria established in that section for the possession and self-administration of an asthma inhaler by a pupil.
