Cave and Technical Diving
DEFINITION: A Diving Incident is any error or unplanned event that could, or indeed did, reduce the safety margin for a diver on a particular dive. The error may have been made by anyone involved with the dive. It may also include equipment problems. The incident may have been preventable or unpreventable. Most incidents don't cause harm, but reporting such incidents will give valuable information when considered with other incidents. This form focuses on any incident occurring before, during or after a cave or technical dive*.

*Definition: Planned decompression, overhead environment, planned depth>40m, gas other than air or EANx 22-40% oxygen, use of rebreather.
