A certified scuba diver using air or other breathing mixtures should be aware of the risks associated with diving, and he is fully responsible for his actions. Scuba divers should not engage in diving and try to use air or other breathing mixtures if they do not want to completely complete the preparatory course, pass the assessment exams for a certificate, constantly maintain their skills and knowledge at the proper level through active participation in dives, and be responsible for any injury or death that may occur during diving.
