When diving with nitrox, which method enhances safety margins?

• A. Using recreational dive tables
• B. Diving alone without a buddy
• C. Using the same tools as when diving on air
• D. Performing deeper dives

Answer: (C)

When diving with nitrox, using the same tools as when diving on air enhances safety margins because the fundamental principles of dive planning, monitoring, and safety remain applicable. While nitrox provides a higher percentage of oxygen, which can reduce nitrogen absorption, divers still need to follow standard diving practices including managing exposure times, understanding oxygen toxicity limits, and adhering to specific no-decompression limits. Utilizing familiar tools and methods ensures that the diver is following established procedures for safe diving, including the use of dive computers or tables specifically designed for nitrox. This continuity in approach aids in effectively managing the diver’s exposure to both nitrogen and oxygen during dives. In contrast, relying solely on recreational dive tables designated for air, diving alone without a buddy, or performing deeper dives could compromise safety. Recreational dive tables may not accurately account for the different gas mixes, diving alone removes the critical safety aspect of having a partner for assistance, and deeper dives increase risk exposure due to potential higher partial pressures of oxygen.
