What is the general recommendation for scuba equipment used with enriched air?

The recommendation that scuba equipment must meet oxygen service specifications is rooted in the unique properties of enriched air (also known as nitrox) and its interaction with materials used in traditional diving gear. Enriched air typically contains a higher percentage of oxygen than regular air, which increases the risk of fire or equipment failure if non-compliant materials are used.

Using equipment that meets oxygen service specifications ensures that all parts of the scuba system, such as regulators, tanks, and hoses, are constructed from materials that can safely handle higher concentrations of oxygen. This is crucial for maintaining safety and reliability while diving with enriched air, as compromised equipment can pose severe risks.

Having standard equipment without appropriate modifications may not provide the necessary safety assurance when diving with enriched air, and disregarding oxygen compatibility can lead to dangerous situations. Thus, adherence to oxygen service standards is essential for safe diving practices.
