level certification for most recreational divers advises them to dive only in conditions similar to those in which they were trained, and to a maximum depth of 18 m, with no decompression obligation. This also encourages the diver to attend further training if they wish to achieve more than minimum competence. The training is short, convenient, and minimal. The cost is low in absolute terms, but accumulates with further training, for those few who undertake it. Professional diver training, and the associated assessment and certification of competence, are usually based on occupational health and safety legislation, and also covered by the employer's duty of care. The training standards are usually aligned with internationally recognised standards, and are expected to follow quality assurance procedures. The professional diver with entry level qualification is expected to perform duties as working diver, diver's attendant, and standby (rescue) diver, and must be competent and fit to perform all these tasks, as well as the basic skills of staying alive underwater and not getting injured, and the work involved in setting up the site and demobilisation after the job.

20: 894: 932: 218: 2046: – Diver accompanying another diver in a reciprocal assistance arrangement. Recreational divers are expected to act as in-water standby divers to their dive buddies on a reciprocity system: Each diver should be capable of assisting their buddy in any reasonably predictable contingency that may occur on the planned dive. Standard recreational diver training includes some assistance skills relevant to the expected range of contingencies that may be experienced by divers who dive within the limitations specified in their certification, at the skill level indicated by their certification, and under conditions in which they have appropriate experience, assuming that not too much competence has been lost due to lack of practice in the relevant skills, and that both divers follow the recommended procedures. This system can work very well when the dive buddies are familiar with each other's equipment, skills and behaviour, and have prepared for the dive effectively. 831: 1267:

employer to ensure that their employees are competent to do the job for which they are hired, and for the contractor to ensure that they deploy personnel who are competent to do the job for the client. IMCA provides guidance for assessment of several key offshore diving competences, which are transferable between IMCA member employers, but is not directly involved in the assessments. Some of these competences are renewable periodically, to ensure that the diver is currently competent. Portfolio of evidence based systems are used where the diver keeps a record of assessments, verification records and evidence in the form of competence appraisal forms, work records and testimonials by competent witnesses. Where competence is shown by records of formal education and training by a reputable organisation this may be recognised, but a significant part of training may be on the job.

1573: 902: 2081:, also known as diving systems technician – Person who maintains, repairs and tests diving and support equipment. Equipment technicians are generally primarily trained as mechanical or electrical engineering technicians, with specialisation training in specific diving equipment. The technician training is usually through a regular trade school, technical college or similar establishment, and the specialisation training is generally through training courses and workshops run by the equipment manufacturers or their agents. There are also some training courses run by commercial diving schools which cover a range of skills for maintenance and repair of commonly used and generic diving and support equipment. 1352: 2058:– A diver who acts in support of a technical dive team or a record attempt. The support diver is an informal equivalent of a stand-by diver, with a role specific to the dive, which may include availability to assist in case of an emergency, transport decompression gases to divers in the water, carry messages between divers and the surface group. A support diver will usually have rescue diver certification, and whatever other certification is appropriate to the depth and environment of the part of the dive they will support. Complex and high-risk expeditions may use several support divers for the various stages of the dives. There is no specific training for this role. 1286: 797:, which includes exercise of important existing skills in a stressful and distracting environment to develop the ability to perform them reliably in spite of the circumstances, can be used to prepare divers to function effectively under high-stress conditions. This is done after the diver has mastered the skills in a benign environment under conditions conducive to learning and retention of the skills. This form of training is generally not used in recreational diver training, and is more likely to be encountered in military and other professional diving, and occasionally in technical diver training. It is not usually required by the training standards. 567:, can be as formal, detailed and extensive as most professional dive plans. A professional diving contractor will be constrained by the code of practice, standing orders or regulatory legislation covering a project or specific operations within a project, and is responsible for ensuring that the scope of work to be done is within the scope of the rules relevant to that work. A recreational (including technical) diver or dive group is generally less constrained, but nevertheless is almost always restricted by some legislation, and often also the rules of the organisations to which the divers are affiliated. 1877: 295: 2052: – Recreational scuba certification emphasising emergency response and diver rescue. Rescue diver training provides the recreational diver with some of the assistance skills provided as standard in most professional entry-level diver training. These may include basic first aid with CPR, emergency oxygen administration for diving accidents, and managing a panicked or unresponsive diver underwater or at the surface. One or more rescue divers may be part of the surface support team for a major technical dive, but mostly the training is a prerequisite for divemaster and instructor training. 553:

dives, but the complexity and detail considered may vary enormously. In most professional diving, dive planning is mainly the responsibility of the supervisor, but the diver is expected to understand the process sufficiently to know when it has been done correctly, and what variations might be acceptable. In recreational diving, unless under training, the diver is generally considered equally responsible for the planning of any dive they participate in, along with the other involved divers, so dive planning at the level of certification is an important aspect of recreational diver training.

for-profit agencies, which maximise profit and customer convenience by providing a larger number of shorter courses with less content and fewer skills per course. The more advanced skills and knowledge, including courses focusing on key diving skills like good buoyancy control and trim, and environmental awareness, are available by both routes, but a large number of divers never progress beyond the entry level certification, and only dive on vacation, a system by which skills are more likely to deteriorate than improve due to long periods of inactivity. This may be mitigated by

These may be specified in the training standard associated with the specific registration, but training standards can change over time and the skills required for original registration may no longer correspond in all details to the current standard, particularly where equipment use in the industry has changed over time. A diver who has been consistently employed can be reasonably expected to remain up to date with industry developments, but there may be cases where divers and supervisors do not keep up with developments. Periodical

2034: – Person who trains and assesses underwater divers. Similar to recreational diving certification systems, but requires membership and registration with the certification organisation. Cross-over training is usually available, and multiple certification and membership is common. Instructor training is generally a relatively intensive program run by a diving instructor registered by the training agency as a course director, or some similar title. The training programmes tend to have titles like "Instructor Development Course" (PADI) or "Instructor Training Course" (NAUI). 823: 439:

psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short-term survival. Other equipment allows the diver to operate in relative comfort and efficiency, or to remain healthy over the longer term. The performance of the individual diver depends on learned skills, many of which are not intuitive, and the performance of the team depends on competence, communication, attention and common goals.

347: 1565: 1212:(IDSA) was formed in 1982 with the primary purpose of developing common international standards for commercial diver training. The association is concerned with offshore, inshore and inland commercial diving and some specialist non-diving qualifications such as diving supervisors, diving medical technicians and life support technicians. It has published international diver training standards based on the consensus of members which provide a basic standard of comparison for commercial diver training standards, with the stated intention of: 530:

equipment. Most further training provides knowledge and skills allowing diving in acceptable safety in the expanded range of conditions, and with the equipment associated with the specific training programme. Prerequisite competences are stipulated to ensure that the diver has the skills and knowledge to seamlessly continue with further training without critical gaps in competence or understanding, which could lead to unsafe diving. Skill retention and improvement depend on practicing the skills sufficiently after initial training.

2075: – Person who blends breathing gas mixtures for scuba diving and fills diving cylinders. Recreational (technical) diving gas blenders may be trained and certified by a recreational diver training agency. This does not necessarily indicate legal competence to blend gas or to fill for other people, particularly in a commercial environment. Recreational mixed gas users are generally trained to analyse the gases they may use for diving within the scope of their diving certification, but blending is beyond this scope. 545: 1975: – Professional diving team leader responsible for safety. Usually regulated by the same legislation as for professional divers. Diving supervisor candidates are generally selected from the pool of competent, reliable and experienced divers with leadership and management potential employed by a contractor to receive specialised additional training and assessment in dive planning, risk assessment, site management and emergency management by a commercial diving school. 1613: 1469: 1411: 1310: 1138: 1098: 2017: – Person who trains and assesses underwater divers. Usually regulated by the same legislation as for professional divers. Diving instructor candidates are generally selected from the supervisors employed by a diving school who have shown a high level of understanding of diving theory and practice, and the ability to teach. They are given further training in adult and occupational education, before the school can apply for registration for the instructor candidate. 2069: – Person who operates a diving air compressor. Most professional divers are trained in the operation of high pressure breathing air compressors within the scope of diving operations, but may not be legally competent to operate the same equipment as a vendor. Surface-supplied divers are generally trained in the operation of low pressure diving air compressors, but this is not specifically a diving skill, and a competent non-diver may be employed in this role. 14523: 1655: 14593: 1930:(BSAC) training has always had a technical element to its higher qualifications, however, it has recently begun to introduce more technical level Skill Development Courses into all its training schemes by introducing technical awareness into its lowest level qualification of Ocean Diver, for example, and nitrox training will become mandatory. It has also recently introduced trimix qualifications and continues to develop closed circuit training. 671: 14581: 957:– the knowledge about things, which is more important to the instructor. This is generally indicated in the assessment criteria and tools for divers who must safely dive, and supervisors and instructors who already know how to dive safely, but must be able to recognise and assess the hazards of a specific dive plan and manage the dive or explain the hazards and procedures of diving and their possible consequences to the learner diver. 14547: 923:

skills used underwater are more complex and difficult to learn than diving skills – it is quicker to train a skilled welder to dive well than to train a skilled diver to weld well. This principle holds particularly for professional skills. A marine scientist or archaeologist may require 3 to 5 years full-time university study to become competent in their chosen field, but can be trained to do the relevant diving in about a month.

and to build confidence in their equipment and themselves. Diver practical training starts with simple but essential procedures, and builds on them until complex procedures can be managed effectively. This may be broken up into several short training programmes, with certification issued for each stage, or combined into a few more substantial programmes with certification issued when all the skills have been mastered.

management, situational awareness, communicating with the dive team, buoyancy and trim control, mobility in the water, ascent, emergency and rescue procedures, exit from the water, unkitting after the dive, cleaning and preparation of equipment for storage and recording the dive, within the scope of the diver's certification. Some of these skills affect the diver's ability to minimise adverse environmental impact.

988:– Documents which define the minimum levels of competence acceptable for a person to be registered as a diver against the specified standard. As a general rule, there will be a number of safety critical skills which must always be demonstrated as competent, and other skills and knowledge which require general competence, but where some leeway can be tolerated. 1003:– Periodical re-assessment of the competence of training staff and adequacy of staff, equipment, documentation and venues, by personnel authorised by the certification agency or registration authority. These requirements may be specified in the training standard or a code of practice or similar document provided by the certification or registration authority. 1522:. These represent the minimum level of training and competence required to allow scientists to participate freely throughout the countries of the European Union in underwater research projects diving using scuba. Certification or registration by an authorized national agency is a prerequisite, and depth and breathing gas limitations may apply. 279:. Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment. All of these may affect diver performance and safety. 1461:

legal duty of care to other divers. The duty of care to a recreational dive buddy is poorly defined and with some exceptions, the diver is not legally obliged to dive with a buddy unless they choose to.
