Andi-EuropeANDI was formed in February of 1989, in an effort to standardize Oxygen-Enriched-Air diving practices, and to formulate a standard teaching format for the training of Enriched-Air Nitrox (EAN) instructors. ANDI began to promote the use of EAN within the recreational diving realm. Since this 30 year-old practice was considered "experimental" by the established recreational training agencies, ANDI's first market was the newly emerging segment of the recreational community referred to as "technical divers". ANDI's first innovation was the world's first EAN instructor's teaching manual which clearly demonstrated how "SafeAir" diving could apply to all recreational diving activities and became the standard for others to emulate. ( Note: "SafeAir" is ANDI 's registered term for EAN that meets higher standards of purity. |

Why ANDI is saying since '88 that the “40% rule” is a myth !While Luxfer Cylinders can certainly be considered an authority on issues surrounding Oxygen equipment issues, Luxfer consulted heavily with ANDI for their specific experience within the SCUBA industry and because of ANDI’s reputation as having the only consistent message compatible with their’s and other industry experts that Luxfer does business with. As a matter of fact, the only Oxygen-service training program that Luxfer mentions on their site is that of ANDI’s! |

LevelsysteemIn order to better differentiate the many programs and their scope of training ANDI attaches a ”level of training”, 1 through 5 for every program. Involving diving skills. Non-diving oriented courses have no levels. Level 1courses will follow these same limitations: 30m max depth, No-Stop-Required profiles, no decompression training, 1.45 PO2, 4.0 PN2 and information of a less complete or less technical nature. For example, only SafeAir 32 and 36 may be used by LSU L1 students. Level 2courses can be expected to be of an advanced recreationascope of training. Only two cylinders and up to two gases may be employed to limit the task loading. This is essentially the recreational limits that are accepted world-wide: 40m maximum depth, No-Stop-Required profiles, no decompression training, 1.45 PO2, 4.0 PN2 and information content of a more complete or more technical nature. For example, the Cavern Diver course is a Level 2 program. A twin-set of cylinders with another gas in an RBS is beyond L2 task loading. Level 3training encompasses the first level of what has become known as “technical diving”.In general, a more experienced recreational diver is the student prerequisite. Three cylinders and three gases are the task loading limits. In addition the training is limited to 50m maximum depth, 1.45 PO2, 4.5 PN2, full decompression training procedures with decompression ceilings limited to 9 metres - 30 minutes and exposure limited to 1.6 PO2, information content of a complete and technical nature. For example, the Cave Diver course is a Level 3 program. Level 4is considered an “explorer’s” program. The training expands on the Level3 material more in practical experience than in theory. The Level 4 program does not extend the depth limits beyond that of a Level 3 program. Depth is not the goal here. The Level 4course prepares the diver to plan and execute “mission oriented” activities. The training involves operating at the reasonable limits of SafeAir diving and incorporates into the dive plan unlimited gas switches and unlimited decompression. For example, the Cave Explorer course is a Level 4 program. Level 5formats are exploration courses and involve the use of other inert gases (in addition to Nitrogen). The operational limits are expanded to 100m maximum depth, 1.45 PO2, 4.5 PN2, with unlimited decompression ceilings. Oxygen exposures for decompression are still limited to 1.6 PO2, and the information content is of the most complete and technical nature. |
