Which of the following is NOT one of the five rules of accident analysis?

The statement "Trust all diving equipment" is not one of the five rules of accident analysis because it implies a level of complacency and blind faith in equipment that is contrary to safety practices in diving. In accident analysis, it is vital to maintain a critical perspective on all aspects of a dive, including equipment reliability. Proper protocols emphasize careful inspection and maintenance of diving gear to ensure its functionality and safety. This approach is essential in preventing accidents, as even high-quality equipment can fail if not correctly maintained or if it is improperly used.

In contrast, the other principles, such as seeking proper training, maintaining a continuous guideline, and using appropriate and well-maintained equipment, emphasize proactive measures in dive safety. They advocate for thorough preparation, use of reliable communication methods while diving, and ensuring that all gear is adequately serviced and fit for purpose to minimize risks associated with diving in cavern environments.
