The DAN Foundation is a 501(c)(3) tax-exempt nonprofit corporation. ID#56-1696689 MISSION DAN helps divers in need of medical emergency assistance and promotes dive safety through research, education, products and services. Divers Alert Network ® (DAN ® ), a nonprofit organization, exists to provide expert medical information for the benefit of the diving public. DAN’s historical and primary function is to provide timely information and assistance for underwater diving injuries, to work to prevent injuries and to promote dive safety. Second, DAN promotes and supports underwater dive research and education, particularly as it relates to the improvement of dive safety, medical treatment and first aid. Third, DAN strives to provide the most accurate, up-to-date and unbiased information on issues of common concern to the diving public, primarily — but not exclusively — for dive safety. ALERT DIVER’S PHILOSOPHY Alert Diver ® is a forum for ideas and information relative to dive safety, education and practice. Any material relating to dive safety or dive medicine is considered for publication. Ideas, comments and support are encouraged and appreciated. The views expressed by contributors are not necessarily those advocated by Divers Alert Network. DAN is a neutral public service organization that attempts to interact with all diving-related organizations or persons with equal deference. Alert Diver is published for the use of the diving public, and it is not a medical journal. The use and dosage of any medication by a diver should be under the supervision of his or her physician. DAN does not sell, lease or trade its mailing lists. The appearance of an advertisement in Alert Diver does not imply endorsement by DAN of any product or service shown. Individuals who reply to advertisements in Alert Diver understand that they are volunteering their information to the advertisers and are, therefore, subject to that company‘s mailing policies. 4 | WINTER <strong>2017</strong>
