2. No dives may be conducted to depths greater than 150 fsw (45 msw).

3. All dives must be conducted using EANx (maximum 40% oxygen). A higher EANx (maximum 50% oxygen) may be used at the decompression or safety stops.

4. All appropriate safety or required decompression stops must be performed.

5. Mandatory decompression stops are limited to a maximum of 15 minutes.

6. No dives made me made with a PO2 greater than 1.6.

G. Water Skills Development

1. A confined water session must be completed before conducting any OW dives.

2. Demonstrate proficiency in a variety of dive techniques and employ precision buoyancy control.

a. Swim in a simulated out-of-air situation (without breathing, and exhaling slowly) without a mask for a distance of at least 45 feet (15 meters), and commence gas sharing; or appropriate Rebreather gas management drill for out-of air diver. While gas sharing, swim for 3 minutes, then replace and clear mask.

PSI/PCI, Inc. OXYGEN POLICY AND STANDARDS FOR ENRICHED AIR NITROX (EANx) CYLINDER HANDLING AND INSPECTION

OXYGEN POLICY AND STANDARDS FOR ENRICHED AIR NITROX (EANx) CYLINDER HANDLING AND INSPECTION

Cylinders and valves intended for Enriched Air Nitrox (EANx) service require special cleaning and inspection procedures. This standard addresses the handling, inspection and cleaning of EANx Cylinders. It does not address the important ramifications of handling or transporting high oxygen concentrations.

1. OXYGEN POLICY

A. PSI/PCI, Inc. adheres to Compressed Gas Association (CGA) recommendations concerning oxygen service. These recommendations establish that cylinders containing 23.5% oxygen content, or greater, shall be cleaned and serviced in accordance with CGA pamphlet G-4.1 part 11.2.6.

B. As gas blending is a common method by which EANx cylinders are filled, the oxygen content in any EANx cylinder may reasonably be expected to, at some time, exceed the 23.5% threshold. Therefore, it is PSI, Inc., policy that all EANx cylinders must be cleaned for oxygen service.

2. EANx CYLINDER HANDLING

A. Normal compressed air shall not be introduced into any cylinder marked for EANx service.

1) Any EANx cylinder receiving normal compressed air shall either have its EANx marking removed or be set aside for a formal inspection and oxygen cleaning prior to filling with EANx.

B. Normal scuba cylinders shall not be filled with EANx unless they have been properly prepared for EANx use. This includes:

1) A new formal visual inspection
2) Oxygen cleaning and servicing of the valve
3) Oxygen cleaning of the cylinder
4) Marking the cylinder for EANx service

C. EANx cylinders shall be secured for transportation to minimize cylinder damage.

D. For prolonged storage, EANx cylinders shall be drained to no more than 50 psig and secured in a vertical position.

E. EANx cylinders must be conspicuously marked as to the specific gas mix (oxygen percentage) inside.

3. CYLINDER INSPECTIONS

A. INFORMAL INSPECTION OF EANX CYLINDERS:

1) All EANx cylinders shall receive an informal inspection prior to filling. This informal inspection consists of:

a) Cylinder is within 5 year hydrostatic test/retest period.

b) Cylinder is within maximum 1 year formal visual inspection period.

c) Cylinder codes are valid.

d) Cylinder is examined for external signs of damage. Any found damage is within CGA and PSI limits.

e) Cylinder is properly marked as having been cleaned for EANx use.

2) Cylinders which fail to comply with any part of 3A 1) above shall be drained, valve closed, and set aside for a formal inspection by a trained visual cylinder inspector.

B. FORMAL INSPECTION OF EANX CYLINDERS:

1) A formal visual cylinder inspection constitutes a complete examination in accordance with the PSI, Inc. 18 Step Protocol for the visual inspection of compressed air cylinders, with the following modifications:

2) When discharging pressure from EANx cylinders, keep all combustible materials, including grease, oil and other hydrocarbons away.

3) Do not allow clothing to become saturated with the contents of the discharging cylinder.

4) Probes or other objects inserted into the cylinder shall be free of contaminants, petroleum products and body oils.

5) Cylinder valves shall be lubricated with a small amount of oxygen compatible lubricant, such as Crytox or Crystolube MCG111 to the lower valve threads. Dow Corning 111 (or similar product) and petroleum based lubricants SHALL NOT be applied to the valve.

6) The valve o-ring shall be of a material intended for oxygen service, such as Viton A.

7) Cylinder shall be oxygen cleaned in accordance with CGA pamphlet G-4.1 prior to reassembly and filling.

8) In addition to normal visual inspection procedures using a bright white light, an EANx cylinder shall also be visually inspected with an ultraviolet (black) light to determine the presence of unacceptable hydrocarbons. Repeatedly oxygen-clean the cylinder until no hydrocarbons are detected.

9) Cylinder shall be conspicuously marked as to its intended service and content.

1. A safety or decompression gas cylinder (if used) rigged as either a pony or stage cylinder. Gas cylinders must be oxygen clean and oxygen serviceable where needed.

F. Program Limits

1. There may be no more than 4 students per Instructor. This ratio may be increased by 2 students for each assisting IANTD Divemaster, up to a maximum of 8 students with 2 IANTD Divemasters per class session.

2. No dives may be conducted to depths greater than 150 fsw (45 msw).

3. All dives must be conducted using EANx (maximum 40% oxygen). A higher EANx (maximum 50% oxygen) may be used at the decompression or safety stops.

4. All appropriate safety or required decompression stops must be performed.

5. Mandatory decompression stops are limited to a maximum of 15 minutes.

6. No dives made me made with a PO2 greater than 1.6.

G. Water Skills Development

1. A confined water session must be completed before conducting any OW dives.

2. Demonstrate proficiency in a variety of dive techniques and employ precision buoyancy control.

a. Swim in a simulated out-of-air situation (without breathing, and exhaling slowly) without a mask for a distance of at least 45 feet (15 meters), and commence gas sharing; or appropriate Rebreather gas management drill for out-of air diver. While gas sharing, swim for 3 minutes, then replace and clear mask.

IANTD Recreational Trimix Class - Klamath Falls OR - August 2006

An International Association of Nitrox and Technical Divers (IANTD) Recreational Trimix Class is going to be held in Klamath Falls Oregon in August 2006.

This Program is designed to provide Sport Divers with a breathing medium for extending their dives to Sport Diving Depths by using ENDs in the 40 to 80 fsw (12 to 24 msw) depth ranges. The diver may elect to dive the "mix" on tables or computers.

The IANTD Recreational Trimix Diver qualification may be taught as a single program or combined with a variety of the IANTD Advanced or Specialty Diver Programs.

The Program covers the use of Recreational (Rec) diving mixes in the range of 28 to 40% oxygen with Helium content to provide an END no greater than 80 fsw (24 msw).

The program qualifies divers to do no stop required dives using Recreational Trimix Gas mixtures to a depth of 100 fsw (30 msw) or deeper up to students previous qualification level.

Prerequisites: Must be a qualified Advanced Open Water diver or equivalent and EANx Diver or take the EANx Diver course in conjunction with the Recreational Trimix Diver course.
