Meg Haskell, left, a volunteer with the Stockton Springs Community Library, and Charles “Chas” Hare, director of ambulance services for Stockton Springs and Prospect, demonstrate how to fit Ellie, a Labrador Retriever, with a special oxygen mask in cases of smoke inhalation or other toxic exposures. The library recently donated a set of three masks to the ambulance service in appreciation of the crew’s participation in health literacy programing.
