heavy equipment, being supervisor or standby diver, will only be allotted to those who have the competence and necessary qualifications for that task.
In other instances, regulations can be prohibitive for integration of those ‘at work’ and those who one would like to integrate for their recreation. It is then often possible to have two separate procedures for two separate teams, operating under different regulations and different chains of command, but, for instance, still referring to the same safety backup. Preparing a safety policy for such a situation is a somewhat more daunting task, in which employer responsibility, liability and insurance need to get as much extra attention as the division of tasks and the avoidance of interference of one team with the other.
Mixed-team diving can thus be complicated due to different organizational embedding of the parti- cipants, and different levels of expertise or standards of training received by team members in a country with varying requirements for recreational and professional divers. In some settings, this might even be further complicated if the project has a team comprised of international members. Nevertheless, international cooperation is very desirable (see Chapter I, Rule 8), and so is the involvement of local and recreational divers (Chapter XIV).
The inclusion and basic requirements of non- archaeologists will vary from country to country, and be determined by the regulating authority or those overseeing the project or dive operations. In order for the non-archaeologists to be included in a form of ‘responsible participation’, their skills and level of technical expertise must be taken into consideration. This is best facilitated by establishing their participation in the project dive plan, which should be specific to mixed teams. In all instances, communication procedures and agreement upon signals used should be clear, and operating and safety standards must be maintained at the same level for all participants. In some instances, particular codes of practice can offer a basic set of standards that guides the participants or projects with mixed teams (see applicable legislation).
