Residents can sign up for public safety alerts on their smartphones, through free downloads. The connection is available through a contract with Emergency Communications Network LLC, according to Glenn Pratt, director of emergency management for Cohasset. “The new platform will serve as one additional tool to help inform the community and visitors about important information that may impact their safety,” Pratt said.
