Effective tourism safety risk prevention and control can reduce the incidence of tourism safety accidents, so that tourism enterprises and tourists can avoid losses caused by tourism safety accidents. Based on the concept of risk chain proposed by Merkhofer, the causes of tourism safety accidents were analyzed, and the model of accident causation chain was constructed, and it was pointed out that the ideas of tourism safety risk prevention and control can be divided into three types: risk avoidance, risk prevention and risk reduction. Therefore, to better protect the life and property safety of tourists, we should fully consider and understand the safety risk factors that may be encountered during the travel itinerary, improve travel safety awareness, and learn and master travel safety risk prevention and control methods and coping skills.
