Course Overview
TDI O2 Service Tech teaches the procedures required to prepare and maintain scuba equipment for oxygen exposure and technical mixed gases. The official TDI page describes oxygen equipment service as a critical responsibility in diving operations, with emphasis on oxygen cleaning, material compatibility, contamination control, and safe procedures that reduce fire risk. This is a practical equipment-service course, not a diving skills course.
The course is for dive shop employees, equipment technicians, and divers interested in advanced equipment cleaning, servicing, and care. TDI lists minimum age 18 and proof of several prerequisites, including TDI Nitrox Gas Blender or equivalent, VIP certification through a recognized agency, regulator clinic certification where required, and employment or intent to work with a recognized scuba-related facility, manufacturer, or distributor. Cylinder-only service has a narrower regulator requirement.
Training covers the responsibility of the service technician, oxygen handling, compatible components, lubricants, O-rings, cleaning chemicals, cleaning procedures for cylinders, valves, regulators, and system components, service documentation, and practical proficiency. In High Springs, Florida, it is valuable for operations supporting nitrox, oxygen, and technical mixed-gas diving. Successful graduates may prepare scuba equipment according to their certification level, including equipment or cylinder O2 service technician ratings.
