based on available umbilical length and the ability of the diver to drag it along and the ability of the tenders to drag it back during exit, and can become snagged on obstructions or diverted through line traps. It may need one or more in-water tenders or guide hoops to avoid these problems, and it may not be possible for the standby diver to reach the diver within an acceptable time in an emergency. Another possible problem is hydrodynamic drag in a current.

In some cases the gap between the ship and the bottom or the jetty or dock can be quite small and the visibility may be poor. Fatal accidents have occurred when a diver has run out of air trying to find the way out from under a large flat-bottomed vessel in low visibility.

70:. Confinement can influence diver safety and the ability of the diver to perform the required task. Some types of confinement improve safety by limiting the ability of the diver to move into higher risk areas, others limit the ability of the diver to maneuver, to perform the task of the dive, or to escape to a place of safety in an emergency. The usual types of recreational penetration diving are

and monitored by an attendant. Surface supplied equipment inherently provides a tether, and reduces the risks of regulator first stage freezing as the first stage can be managed by the surface team, and the breathing gas supply is less limited. For the surface support team, the hazards include freezing temperatures and falling through thin ice.
276:. Because diving under ice places the diver in an overhead environment typically with only a single entry/exit point, it requires special procedures and equipment. Ice diving is done for purposes of recreation, scientific research, public safety (usually search and rescue/recovery) and other professional or commercial reasons.

Skills and procedures have been developed for managing the hazards and foreseeable contingencies associated with different circumstances of penetration diving and the equipment suitable for use in each environment. These are generally learned in training for diving in those specific environments, but

The underside of the hull is an overhead environment with no direct vertical access to the surface. As such it constitutes an entrapment hazard, particularly under large vessels where it may be too dark due to low natural light or turbid water to see the way to the side of the hull.

For scuba diving, the risk of getting lost and running out of breathing gas is real and significant. These are the most common factors recorded in diving deaths in penetration diving.

The main generic hazards of penetration diving are being unable to navigate back to the surface and running out of breathing gas before reaching the surface. Both of these hazards are well mitigated by the use of surface supplied breathing equipment, but at the cost of seriously reduced mobility and

The most obvious hazards of ice diving are getting lost under the ice, hypothermia, and regulator failure due to freezing. Scuba divers are generally tethered for safety. This means that the diver wears a harness to which a line is secured, and the other end of the line is secured above the surface

Surface supplied diving reduces the risk of getting lost under an overhead, as the umbilical provides a reliable guideline back to the entry point, and a reliable source of breathing gas with a low risk of out of air incidents, but it can be cumbersome, only allows a limited penetration distance

Cavern diving is an arbitrarily defined, limited scope activity of diving in the naturally illuminated part of underwater caves, where the risk of getting lost is small, as the exit can be seen, and the equipment needed is reduced due to the limited distance to surface air. It is defined as a

Clearance diving, the removal of obstructions and hazards to navigation, is closely related to salvage diving, but has a different purpose, in that the objects to be removed are not intended to be recovered, just removed or reduced to a condition where they no longer constitute a hazard or
