The Divers Alert Network (DAN) is the diving industry's largest association dedicated to scuba diving safety. Serving scuba divers for more than 30 years, DAN provides emergency assistance, medical information resources, educational opportunities and more.

DAN provides coverage to help sick or injured divers. There are two components: DAN Membership providing Worldwide Emergency Evacuation Coverage, and DAN Dive Injury Insurance, covering treatment costs associated with a covered diving incident.

One of DAN's best-known resources is the Emergency Hotlines that are available 24-hours, 7-days a week to help scuba divers in need. DAN also offers a number of non-emergency resources, including DAN Doc, a dedicated diving medical issues website.
