sentences:  In most cases diving for citizen science purposes is not considered occupational diving and therefore does not fall under the occupational heath and safety regulations, as each diver is autonomous and personally responsible for the planning and execution of their dives.Any agreement between two dive buddies regarding mutual duty of care should follow established legislation for that purpose, if it exists in the relevant jurisdiction.If the diver is under the direction of a person appointed by an organisation, this exclusion may fall away as the appointed person becomes responsible for health and safety at the dive site, and the organisation assumes the duty of care of an employer.
