About PSI

PSI, Inc. (Professional Scuba Inspectors) was formed in 1982 and is incorporated in Washington State, USA. Affiliate cylinder inspector instructors are located in 10 countries. About 200 hands-on visual inspector workshops, serving over 1,200 students, are conducted each year. Training by correspondence is offered to technicians at international locations not served by PSI instructors. PSI is in its 23th year, serving the diving (scuba), fire fighting (SCBA) and hydro re-testing industries.

PSI, Inc. founder William (Bill) L. High, a marine scientist living in greater Seattle, Washington, began diving in 1955 and has maintained a constant involvement with the many facets of underwater science, diver equipment, education and training. He led four extended saturation undersea laboratory teams (Tektite, Hydrolab, FLARE, Helgoland) and directed operations of five major deep submersible diving programs. He personally trained over 8,000 persons in basic or specialty diving skills and over 2,000 visual cylinder inspectors. He maintained a parallel career as a Emergency Medical Technician, Diving Medical Technician, hyperbaric chamber supervisor, and emergency room medic.

Bill High served as the first NOAA Diving Coordinator, Vice President of the Underwater Society of America, and President of the National Association of Underwater Instructors (NAUI). He is the recipient of numerous industry honors including NOGI Awards for both Science and Sports, the Greenstone Award, PADI’s Outstanding Achievement Award, NAUI's Hall of honor, and NAUI Lifetime Achievement Award.

Bill is a prolific writer and photographer, having published more than 150 scientific or technical articles, several books, and over 200 photographs. He is a major contributor to each edition of the NOAA Diving Manual.

Single handedly, Bill researched and developed the technical training program for inspection of selected high-pressure cylinders. His devotion to life support cylinder safety influenced the gas industry throughout North America and at international locations. The PSI, Inc. training receives support from federal agencies, military, scuba instructor, fire industry associations, and cylinder manufactures including Luxfer, Catalina, Pressed Steel Tanks, and Structural Composites Inc.

PSI, Inc. visual inspector workshops exceed the training standards of the U.S. Department of Transportation (DOT), Occupational Safety and Health Administration (OSHA), Compressed Gas Association (CGA), and Transport Canada (TC). It meets compliance requirements for U.S. Hazardous Materials Training (high-pressure air and other gases are classified as hazardous materials) required of all employees exposed to the potential hazards of pressurized air).

In July of 2004, PSI moved to it's new Training Center located in the Seattle suburb of Woodinville, WA with Bill High as President and Mark Gresham as General Manager.
