Task loading

Task loading in scuba diving is a term used to refer to a multiplicity of responsibilities leading to an increased risk of failure on the part of the diver to undertake some key basic function which would normally be routine for safety underwater.[1][2]

Common examples[edit]

Common examples of activities which can cause task loading are:

Task loading represents an elevated risk when a new activity is undertaken by an inexperienced diver. A diver learning how to use a drysuit, or starting underwater photography, will need to dedicate considerably more attention to the proper functioning of the new and unfamiliar piece of equipment which leads to the elevated risk of neglect of other responsibilities. Those risks will normally diminish with experience.

Common examples of routine functions that can be overlooked as a result of task loading are:

Task loading is often identified as a key component in diving accidents, although statistically it is difficult to monitor because divers of differing levels of experience can cope with a more complex array of tasks and equipment.[6] Whilst simply getting used to using a drysuit can call for great levels of attention in an inexperienced diver, it would be a routine piece of equipment for an experienced technical diver to use, whilst carrying a camera and also penetrating a cave or wreck at depth or using a DPV.
