Enriched Air Nitrox Course - Sydney - Alexandria

This course is designed to train certified divers to safely

• Use nitrox breathing gas with an oxygen percentage ranging from 22 percent to 40 percent.
• Plan dives within modified No Decompression units using a programable personal nitrox dive computer or by using dive planning software.
• Describe the hazards of handling high-oxygen gas mixtures, and the basic requirement for cleaning scuba gear for high-oxygen environments (i.e. mixes up to 40% oxygen)
• Calculate the Maximum Operating Depth of an analyzed nitrox breathing gas at a target depth between 6 meters/20 feet and 40 meters/130 feet and a partial pressure of oxygen between 1.0 and 1.6 bar.
• Understand the relationship between oxygen partial pressure and NOAA time limits to determine oxygen CNS loading.
• List the signs and symptoms of Central Nervous System oxygen toxicity.
• Understand how to calibrate a simple oxygen analyzer and use it to measure O2 percentage in a cylinder and to familiarize themselves with the standard procedures for gas analysis.
• Demonstrate how to label an analyzed diving cylinder properly.
