NITROX Diver
TDI Certification Courses - Technical Diving
Introduction
This is the entry-level certification course for recreational
divers wishing to utilize enriched air Nitrox (EAN)
as a breathing gas. The objective of this course is
to train divers in the benefits, hazards, and proper
procedures for using Nitrox mixes from twenty two (22)
to forty (40) percent oxygen content.
Student Pre-Requisites
The student must:
1. Be a minimum age of fifteen (15).
2. Have a Minimum certification of Open Water Diver
or a current enrollment in an Open Water Diver course.
Course Structure, Duration and Training Materials
Open Water Execution:
1. Two (2) Nitrox dives are recommended but are not
required. However, optional dives are desirable to effectively
demonstrate the advantages of EAN use in practical field
use. If scheduled, no direct instructor supervision
is required but dives should not be conducted in environments
that may exceed the existing skill or depth levels of
the student.
Duration:
2. The suggested number of classroom hours is three
(3).
Required material:
1. TDI Understanding Nitrox diver manual
Optional Material
1. TDI Plastic EAD table
2. TDI Understanding Nitrox power point
Required Skill Performance and Graduation Requirements
Maximum training depths shall not exceed forty (40)
msw / one hundred thirty (130) fsw. The following open
water skills must be completed by the student during
all open water dives:
Pre-dive
1. Use TDI Tables to plan a Nitrox dive taking advantage
of EAD calculations. 2. Create a simple written dive
plan for a Nitrox dive to an appropriate depth (MOD
calculated with P02's between 1.3 and 1.6 depending
on environmental conditions).
3. Demonstrate correct use of oxygen analyzer.
4. Demonstrate correct tank management and labeling.
5. Conduct simple pre-dive briefing (may be simulated
if dives are not part of program).
6. Program Nitrox computer - if used -- with appropriate
oxygen percentage if used.
In order to complete this course, students must:
1. Satisfactorily complete the TDI Nitrox Course written
examination.
2. Demonstrate understanding of oxygen analysis for
Nitrox mixtures. |
