What type of certification should a qualified enriched air blender have?

A qualified enriched air blender should have a certification such as Tec Gas Blender because this certification provides the necessary skills and knowledge to safely blend and handle enriched air (nitrox) tanks. The Tec Gas Blender course covers essential topics such as calculating the correct partial pressures of oxygen and nitrogen, understanding the risks associated with handling high oxygen concentrations, and maintaining equipment. This specialized training ensures that the blender is equipped to prevent potential hazards and ensure the safety of the divers who will be using the enriched air for their dives.

In contrast, while having basic diving credentials may be necessary for a fundamental understanding of diving principles, it does not specifically address the skills needed for blending gas. The status of being an instructor may not automatically imply proficiency in gas blending techniques. A license from a local authority might be required for regulatory compliance, but it does not guarantee the technical expertise required for safe gas blending.
