recognised by the local communities to be worth more in good condition than degraded by inappropriate use, which encourages conservation efforts. During the 20th century recreational scuba diving was considered to have generally low environmental impact, and was consequently one of the activities permitted in most marine protected areas. Since the 1970s diving has changed from an elite activity to a more accessible recreation, marketed to a very wide demographic. To some extent better equipment has been substituted for more rigorous training, and the reduction in perceived risk has shortened minimum training requirements by several training agencies. Training has concentrated on an acceptable risk to the diver, and paid less attention to the environment. The increase in the popularity of diving and in tourist access to sensitive ecological systems has led to the recognition that the activity can have significant environmental consequences.

reaches the cochlea independently, by bone conduction. Some sound localisation is possible, though difficult. Human hearing underwater, in cases where the diver's ear is wet, is less sensitive than in air. Frequency sensitivity underwater also differs from that in air, with a consistently higher threshold of hearing underwater; sensitivity to higher frequency sounds is reduced the most. The type of headgear affects noise sensitivity and noise hazard depending on whether transmission is wet or dry. Human hearing underwater is less sensitive with wet ears than in air, and a neoprene hood causes substantial attenuation. When wearing a helmet, hearing sensitivity is similar to that in surface air, as it is not greatly affected by the breathing gas or chamber atmosphere composition or pressure. Because sound travels faster in heliox than in air, voice

General physical fitness requirements are also often specified by a certifying agency, and are usually related to ability to swim and perform the activities that are associated with the relevant type of diving. The general hazards of diving are much the same for recreational divers and professional divers, but the risks vary with the diving procedures used. These risks are reduced by appropriate skills and equipment. Medical fitness to dive generally implies that the diver has no known medical conditions that limit the ability to do the job or jeopardise the safety of the diver or the team, that might get worse as an consequence of diving, or unacceptably predispose the diver to diving or occupational illness.

resulting in a pressure difference between the tissues and the gas space, and the unbalanced force due to this pressure difference causes deformation of the tissues resulting in cell rupture. Barotraumas of ascent are also caused when the free change of volume of the gas in a closed space in contact with the diver is prevented. In this case the pressure difference causes a resultant tension in the surrounding tissues which exceeds their tensile strength. Besides tissue rupture, the overpressure may cause ingress of gases into the adjoining tissues and further afield by bubble transport through the circulatory system. This can cause blockage of circulation at distant sites, or interfere with the normal function of an organ by its presence.

Estimating the number of active scuba instructors in the US and internationally is also difficult. Over 300 individual certifying agencies train and certify divers, dive leaders, and instructors, but there are also an unknown number of instructors who are registered with more than one agency. PADI reported 137,000 professional members (instructors and divemasters) worldwide in 2019. On the assumption that PADI represents 70% of the market share, the number of instructors globally may be about 195,000. 2240:, equipment misuse, entrapment, rough water conditions and pre-existing health problems. Some fatalities are inevitable and caused by unforeseeable situations escalating out of control, but the majority of diving fatalities can be attributed to human error on the part of the victim. During 2006 to 2015 there were an estimated 306 million recreational dives made by US residents and 563 recreational diving deaths from this population. The fatality rate was 1.8 per million recreational dives, and 47 deaths for every 1000 emergency department presentations for scuba injuries. 636: 1044: 2093: 1874:

cases, what might be a life-threatening emergency to an untrained or inadequately skilled diver, is a mere annoyance and minor distraction to a skilled diver who applies the correct procedure without hesitation. Professional diving operations tend to adhere more rigidly to standard operating procedures than recreational divers, who are not legally or contractually obliged to follow them, but the prevalence of diving accidents is known to be strongly correlated to human error, which is more common in divers with less training and experience. The

1459: 1019:(ROVs) can carry out some functions of divers. They can be deployed at greater depths and in more dangerous environments. An AUV is a robot which travels underwater without requiring real-time input from an operator. AUVs constitute part of a larger group of unmanned undersea systems, a classification that includes non-autonomous ROVs, which are controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications AUVs are often referred to as unmanned undersea vehicles (UUVs). 953: 2412: 2648: 2458:. Professional divers are generally legally obliged to carry out and formally record these measures, and though recreational divers are not legally required to do many of them, competent recreational divers, and particularly technical divers, generally perform them informally but routinely, and they are an important part of technical diver training. For example, a medical statement or examination for fitness, pre-dive site assessment and briefing, safety drills, thermal protection, equipment redundancy, 396: 2201:

operations are also constrained by the physical realities of the operating environment, and expensive engineering solutions are often necessary to control risk. A formal hazard identification and risk assessment is a standard and required part of the planning for a commercial diving operation, and this is also the case for offshore diving operations. The occupation is inherently hazardous, and great effort and expense are routinely incurred to keep the risk within an acceptable range. The

All of these modes are still in use and each has a range of applications where it has advantages over the others, though diving bells have largely been relegated to a means of transport for surface-supplied divers. In some cases combinations are particularly effective, such as the simultaneous use of surface orientated or saturation surface-supplied diving equipment and work or observation class remotely operated vehicles. 2153: 18996: 19066: 2131:, treatment of diving accident injuries and diving fitness. The field includes the effect on the human body of breathing gases and their contaminants under high pressure, and the relationship between the state of physical and psychological health of the diver and safety. In diving accidents it is common for multiple disorders to occur together and interact with each other, both causatively and as complications. Diving medicine is a branch of 19054: 19020: 2254:, it is usually the consequence of an uncontrollable series of events in which drowning is the endpoint because it occurred in water, while the initial cause remains unknown. Where the triggering event is known, it is most commonly a shortage of breathing gas, followed by buoyancy problems. Air embolism is also frequently cited as a cause of death, often as a consequence of other factors leading to an uncontrolled and badly managed 2364:

generally avoidable by a well-trained, intelligent and alert diver, working in an organised structure, and not under excessive stress, it was concluded that the low accident rate in professional scuba diving is due to this factor. The study also concluded that it would be impossible to eliminate all minor contraindications of scuba diving, as this would result in overwhelming bureaucracy and bring all diving to a halt.

19008: 8842: 469:, or inefficient removal, to the exacerbation of the toxic effects of contaminants in the breathing gas due to the increased concentration at high pressures. Hydrostatic pressure differences between the interior of the lung and the breathing gas delivery, increased breathing gas density due to ambient pressure, and increased flow resistance due to higher breathing rates may all cause increased 1566:, which suggested that decompression following schedules based on conventional models results in asymptomatic bubble formation which must then be re-dissolved at the decompression stops before it can be eliminated. This is slower than allowing the gas to be eliminated while it is still in solution, and indicates the importance of minimising bubble phase gas for efficient decompression. 988:, with elaborate joints to allow bending, while maintaining an internal pressure of one atmosphere. An ADS can be used for dives of up to about 700 metres (2,300 ft) for many hours. It eliminates the majority of physiological dangers associated with deep diving – the occupant does not need to decompress, there is no need for special gas mixtures, and there is no danger of 1642:, are environments of low risk, where it is extremely unlikely or impossible for the diver to get lost or entrapped, or be exposed to hazards other than the basic underwater environment. These conditions are suitable for initial training in the critical survival skills, and include swimming pools, training tanks, aquarium tanks and some shallow and protected shoreline areas. 1898:

A narrow field of vision caused by a small viewport in a helmet results in greatly reduced stereoacuity, and an apparent movement of a stationary object when the head is moved. These effects lead to poorer hand-eye coordination.

2258:, occasionally aggravated by medical conditions. About a quarter of diving fatalities are associated with cardiac events, mostly in older divers. There is a fairly large body of data on diving fatalities, but in many cases the data are poor due to the standard of investigation and reporting. This hinders research which could improve diver safety. 902:(TUP). Divers can breathe air or mixed gas at the bottom and are usually recovered with the chamber filled with air. They decompress on oxygen supplied through built in breathing systems (BIBS) towards the end of the decompression. Small bell systems support bounce diving down to 120 metres (390 ft) and for bottom times up to 2 hours. 841:. Decompression at the end of the dive may take many days, but since it is done only once for a long period of exposure, rather than after each of many shorter exposures, the overall risk of decompression injury to the diver and the total time spent decompressing are reduced. This type of diving allows greater work efficiency and safety. 111:
