Why should only qualified, reputable enriched air blenders fill enriched air cylinders? - ANSWER They have the proper training and equipment to manage the two primary concerns associated with enriched air cylinders. 2. What is the potential hazard of improper enriched air filling procedures? - ANSWER Fire/explosion and having a different mix of oxygen than you asked for 3a. What is the primary benefit of using enriched air? - ANSWER It exposes you to less nitrogen than when you dive with air. 3b. How does using enriched air affect no stop limits? - ANSWER It allows longer no stop limits because you are absorbing less oxygen. 4. Why is it too simplistic to say enriched air is safer than air when diving will within air no decompression limits? - ANSWER Higher oxygen levels create a potential hazard that hardly exists in air diving within recreational limits. 5. What is "enriched air"? - ANSWER Enriched air is any nitrogen/oxygen gas blend with more than 21% oxygen. 6. How does using enriched air affect narcosis when diving? - ANSWER The current thinking is the narcosis potential is the same. 7. What are three advantages of using an enriched air dive computer for enriched air diving? - ANSWER 1) Computers combine enriched air with multilevel diving for the most no stop time possible. 2) Most models will or can be set to alert you if you accidentally exceed the maximum depth for your gas blend. 3) Dive computers simplify diving planning and execution by calculating both your oxygen exposure and your allowable no stop time, and warn you if you near the limits of either. 8. What is the primary concern regarding enriched air and scuba equipment? - ANSWER High oxygen content. 9. What are the requirements and recommendations for scuba equipment (other than cylinders) used with enriched air with up to 40 percent oxygen? - ANSWER 1) Regulators, BCDs, SPGs, and alternate air sources may be used without modification. 2) Follow manufacturers recommendations. 3) Use oxygen compatible lubricants, o-rings, and other materials as appropriate during service. 4) Have your regulator serviced annually, preferably by a technician qualified to work on enriched air equipment. Have it inspected or recleaned by a qualified technician if you accidentally expose it to anything other than water. 10. Why does enriched air diving require a dedicated cylinder? - ANSWER 1) It is important that no one accidentally confuse an enriched air cylinder for one of normal air. 2) If partial pressure blending with oxygen will be used, the cylinder must meet oxygen service standards. 11. What color coding, stickers (decals) and tags should an enriched air cylinder have? - ANSWER 1) Yellow cylinders should have a 4 inch green band with yellow or white lettering. 2) Non-yellow cylinders should have a 6 inch band with 1 inch of yellow on the top and bottom, green in the middle, and yellow or white
