Is the statement "The MOD for EAN32 is 30 m/99 ft" true or false?

The statement "The MOD for EAN32 is 30 m/99 ft" is false. The Maximum Operating Depth (MOD) for EAN32 (Enriched Air Nitrox with 32% oxygen) is calculated based on the percentage of oxygen in the mixture and the maximum allowable partial pressure of oxygen for safe diving. Generally, for recreational diving, the maximum partial pressure of oxygen should not exceed 1.4 ATA (atmospheres absolute).

Using the formula for MOD:

[

\text{MOD} = \frac{(O2% \times 10)}{(1.4 - \frac{(O2%)}{100})}

]

Substituting in EAN32 gives:

[

\text{MOD} = \frac{(32 \times 10)}{(1.4 - \frac{32}{100})} \approx 34 meters (or about 112 feet).

]

This shows the MOD for EAN32 is approximately 34 meters, which clearly exceeds the claimed maximum depth of 30 m/99 ft in the statement. Therefore, the statement is classified as false based on the correct scientific calculations for MOD.
