List of UK caving fatalities

This is a list of recreational caving fatalities in the United Kingdom. It includes all verified deaths associated with the exploration of natural caves and disused mines in the modern era (post 1880). Deaths involving members of the general public who may have slipped down a shaft, or wandered into a cave without being aware of the risks, have been excluded.

There have been a total of 128 fatalities associated with recreational caving. The main causes of death have been drowning when cave diving, drowning as the result of flooding or negotiating deep water, injuries incurred from falling from a height, and injuries incurred as the result of rock falls. In ten cases the bodies have not been recovered.

The worst incident in UK caving history was the Mossdale Caverns incident in 1967 when six cavers were drowned following an unexpected cloud burst. There have been three incidents when three people have died. The first was when three cavers drowned in Langstroth Pot in 1976 when free-diving short sections of underwater passage as the result of the air in an air bell becoming foul. Three cavers were killed by a rock fall in Ease Gill Caverns in 1988, and three cavers were drowned in the Marble Arch system in 1995.

Porth yr Ogof, in South Wales, accounts for eleven fatalities, nine of which were the result of people drowning when negotiating the exit pool. Ease Gill Caverns and its associated entrances account for ten deaths; Alum Pot and its associated entrances account for six, as does Mossdale Caverns (all from the 1967 incident).

The only case of a caver dying in the UK as the result of becoming stuck was Neil Moss in Peak Cavern in 1959. The cause of death was foul air building up around him.

The following table summarises the major causes of fatality in UK caving by cause and by area. The commonest cause of fatality in the UK is drowning - accounting for a half the deaths when cave diving is included, and 43% when diving is excluded. The second major cause of fatality, when cave diving is excluded, is falling from height which accounts for 20% of fatalities, followed by rock fall which accounts for 14% of fatalities. The 'Other' category includes gas poisoning and asphyxiation.
