Trimix Gas Blender Training
IANTD Trimix Gas Blender training teaches competent personnel how to handle oxygen safely and prepare trimix and heliox breathing mixtures. The current official IANTD page describes the program as a gas-blending course rather than an in-water diving course, with academic sessions and gas-blending sessions that include preparing multiple trimix mixes to specified oxygen and helium tolerances. The course is about accuracy, analyzer use, oxygen and helium handling, compatible equipment, and the discipline required when people will rely on the gas you prepare.
This course is useful for dive-center staff, technical divers, instructors, expedition support teams, and anyone responsible for producing mixed gas in a controlled environment. IANTD states that any person may take the class and does not have to be a diver, with a minimum age requirement. Students should still approach the course seriously, because blending errors can affect decompression planning, narcosis management, oxygen exposure, and the safety of every diver using the cylinders.
Training includes academic work and practical blending sessions using oxygen and helium analysis equipment. In High Springs, Florida, Trimix Gas Blender fits naturally alongside advanced nitrox, trimix, cave, and rebreather training. The expected outcome is practical skill in preparing, analyzing, and documenting trimix and heliox mixtures with a conservative respect for oxygen compatibility, helium accuracy, and the limits of the blending system.
