A free class by Weston EMS on recognizing medical emergencies, hands-only CPR, and how to use a defibrillator. Participants practice on Smart Manikins. 70 percent of out-of-hospital cardiac arrests happen at home. Only 10 percent survive, but immediate CPR doubles or triples that rate. Sign up here. More sessions coming on January 14 and February 4.

As an opportunity to honor Dr. Martin Luther King Jr.’s legacy, help fill snack bags to complement weekend meal bags distributed by Filling in the Blanks to children in need throughout Fairfield, Westchester and Putnam Counties.
