The purpose of this study was to examine the risk factors for injuries on a beach. It is important to know all the risk factors for injuries that can happen in a beach to prevent accidents. Risk factors were grouped in four main categories: beach morphology (BM), beach equipment (BE), lifeguard service (LS), and miscellaneous aspects (MA). All of them were evaluated according to their importance using a survey by Spanish and International experts. Descriptive analysis showed that LS is the main mechanism by which to reduce injuries on a beach. Lifeguard service in-service train-ing is very important as are the affluence and activities developed by the beach patrons, the influences of weather and climate on the beach, and other infrastructures as risk factors for dangers on beaches. The interest in aquatic activities is a social phenomenon that has increased in recent years, due to the increases in leisure time, according to the Spanish National Statistics Institute (2004). Over the last 10 years, Spanish people have spent around 48 min per day in sport practice or physical activities. During that same period, the number of people involved in the national federation of aquatic activi-ties increased from 194,013 in 1993 to 267,125 in 2003. The leisure time increases during holidays lead to a higher involvement in aquatic activities, especially during the summer and spring seasons due to the favorable climate conditions in Spain. This same increase in aquatic participation also can explain the increase in aquatic accidents (American Red Cross, 1995; Branche & Stewart, 2001; Brewster, 1995; Edmonds & Walker, 1999; Graver, 2004; Grenfell, 2002; Thanel, 1998: YMCA, 2001). An accident is defined as an important damage or injury to humans that is associated with high economic costs in some cases and that could have been prevented (Girsek, 1999; Langley, 2004; Saluja et al., 2004). According to the World Health Organization (2003), the most negative effects on health associated with the practice of aquatic activities are eye injury, lacerations, slipping and falling injuries, spinal cord injuries leading to paralysis, head injuries, and drowning. Drowning, defined as the impossibility to breathe due to immersion in water, is the most serious problem related to beach and water use (Bierens, 2005; OMS, J.
