This bill requires the administrator of all "public buildings", as defined in the bill, to maintain a supply of naloxone, inside the building's first aid kit, if any, and in the same location as the building's automated external defibrillator (AED), if any. The building is required to make all reasonable efforts to notify occupants that there is naloxone on the property, where to find it, and to call emergency personnel if naloxone is administered.
