NOAA Oxygen Exposure Chart
The NOAA Oxygen Exposure Limits chart is used primarily for avoiding CNS Oxygen Toxicity problems while diving. The first columm represents the maximum oxygen partial pressure exposure in atmospheres. The second column gives the maximum duration, in minutes, a diver may safely remain in the water at that exposure with the third column representing the maximum allowed exposure in a 24 hour period.
This table is commonly used by divers trained in the use of Enriched Air Nitrox and/or Trimix. Diver's who have not completed training in the use of these specialized gases should not attempt to execute dives using them. The NOAA Oxygen Exposure Limit chart is provided for informational purposes only.
