Which potential hazard should Nitrox divers be aware of related to equipment?

Nitrox divers need to be particularly aware of the compatibility of their equipment with oxygen-rich gas mixtures. When diving with Nitrox, which has a higher percentage of oxygen than regular air, it is crucial that all equipment, including tanks, regulators, and other gear, is rated for high-oxygen environments. Certain materials, such as some plastics and oils, can become hazardous when exposed to high levels of oxygen, potentially leading to equipment failure or a fire risk.

Properly oxygen-compatible equipment ensures the safety and integrity of the diver's gear, maintaining effective operation under the specific conditions of Nitrox diving. This is foundational knowledge for ensuring safe diving practices and avoiding incidents related to equipment malfunction caused by compatibility issues.
