Anecdotal reports suggest that:
- Fires, explosions, equipment incidents where combustion is believed to have occurred, burns, etc., are common in diving equipment using >40% oxygen. These take place despite widespread understanding of the risks, by people who believe they are using safe practices.
- Most of these incidents do not appear in DAN reports because they do not occur during the dive itself. Those that occur during a dive are usually not fatal, and are not reported to DAN for that reason.
- Oxygen is widely used for medical treatment, welding, and other industrial purposes. While fires etc. do occur with these uses, they are extremely rare on a per-cylinder-handled basis (with the exception of extremely common fires caused by individuals smoking cigarettes while using home oxygen)
