The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 24801-1 was prepared by the European Committee for Standardization (as EN 14153-1:2003) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 228, Tourism and related services, in parallel with its approval by the ISO member bodies. ISO 24801 consists of the following parts, under the general title Recreational diving services Safety related minimum requirements for the training of recreational scuba divers: Part 1: Level 1 Supervised diver Part 2: Level 2 Autonomous diver Part 3: Level 3 Dive leader Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 04/23/2007 01:17:19 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 24801-1:2007(E) © ISO 2007 All rights reserved v Introduction The International Standards relating to recreational diving services have been prepared by ISO/TC 228/WG 1 “Diving services”, with the aim of establishing a series of specifications for safety practices and the provision of services. Therefore these International Standards specify: necessary levels of experience and competency of scuba divers and scuba instructors, safety practices and requirements for recreational scuba diving service providers appropriate to the different diving levels. The requirements specified are minimal; they do not preclude the provision of additional training or the assessment by a service provider of additional competencies. These International Standards represent a tool for comparison of existing (or future) qualifications of scuba divers. In no way do they represent a course programme nor do they imply that course programs and scuba diver certifications issued by different nations or training organizations must necessarily correspond to these levels.

It also specifies conditions under which training has to be provided, in addition to the general requirements for recreational diving service provision in accordance with ISO 24803. This part of ISO 24801 applies only to contractual training and certification in recreational scuba diving. 2 Normative references The following referenced documents are indispensable for the application of this document.

Scuba divers at level 1 “Supervised diver” are qualified to dive within the following parameters: dive to a recommended maximum depth of 12 m, dive in groups of up to four level 1 scuba divers per dive leader, make dives which do not require in-water decompression stops, dive only when appropriate support is available at the surface, dive under conditions that are equal or better than the conditions where they were trained. NOTE If accompanied by a scuba instructor, a scuba diver at level 1 “Supervised diver” may gain progressive experience beyond these parameters and develop competency in managing more challenging diving conditions designed to lead to higher qualifications. Where further instruction is required this can only be provided by a suitably qualified scuba instructor. Where only further experience is required, this may be supervised by a dive leader. 5 Prerequisites for training 5.1 General The service provider shall ensure that the client fulfils the following prerequisites to take part in the training course envisaged. 5.2 Minors Documented parental or legal guardian consent shall be obtained when the applicant is a minor.

If the student is not examined by a physician the student shall be obliged to confirm by signature that he or she has understood written information given by the scuba instructor on diseases and physical conditions which may pose diving related risks. Students shall be advised of the importance of appropriate regular medical examinations. 6 Introductory information Information in accordance with ISO 24803 shall be made available to the students prior to, or during the first class meet
