Prepararea gazelor de scufundari, conform standardelor de calitate ANDI, inseamna mai mult decat cateva formule matematice (sau aplicatii desktop/mobil) si cateva valvule ale cilindrilor de gaze.

Cursul dureaza 2 zile (16-18h) si acopera notiuni si proceduri de manipulare ale oxigenului, cerintele de calitate ale gazului de respirat in SCUBA, operatiuni si echipamente

(Oxigen Service: design, compatibilitate, contaminare), formule matematice de calcul ale amestecurilor (in diferite situatii), aplicatii practice etc.

Reglementarile tehnice ANDI International se bazeaza pe cerintele, standardele si procedurile unor agentii si organisme internationale in domeniu:

  Compressed Gas Association - National Fire Protection Association - American Society for Testing and Materials - American National Standards Institute - Industrial Gas Committee

National Aeronautics and Space Administration - Union Carbide Industrial Gases - Occupational Safety and Health Administration

Naval Experimental Diving Unit Reports etc

in anul 1990, ANDI lansa primul program Gas Blender din industria scufundarilor recreationale/agrement/sportive.
