If local laws/standards exist, what might be required for equipment used with enriched air?

When dealing with enriched air, also known as nitrox, it is essential that the equipment used is compatible with higher oxygen content. This is particularly critical because the presence of increased oxygen can create risks such as increased fire hazards and potential damage to equipment not rated for enriched air use.

Special fittings or cleanings ensure that the equipment, including tanks and regulators, is specifically designed or treated to handle the properties of enriched air. Equipment might require special oxygen-cleaning processes to remove contaminants that could ignite in the presence of higher oxygen levels. Additionally, fittings that do not easily allow for the exchange of enriched air can be required to prevent accidental mixing with regular air.

Thus, ensuring that the equipment is equipped with the right fittings and has undergone proper cleaning is vital for safe and effective use of enriched air during dives.
