About PSI/PCI

PSI, Inc. (Professional Scuba Inspectors), also now known as PCI, Inc. (Professional Cylinder Inspectors, Inc.) 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 courses, training over 2,000 students, are conducted each year. Training by correspondence is offered to technicians at international locations not served by PSI/PCI instructors. PSI/PCI is in its 27th year, serving the diving (scuba), fire fighting (SCBA), hydro re-testing and other industries involved with high pressure cylinders.

PSI/PCI, 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 Science, Sports and Distinguished Service, the Greenstone Award, PADI’s Outstanding Achievement Award, NAUI's Hall of Honor, NAUI Lifetime Achievement Award, and DEMA's Reaching Out Award. Bill is the only living diver to achieve 3 NOGI awards!

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. He has published 5 editions of the book Inspecting Cylinders, which is recognized as the authority on high pressure cylinder inspection!

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 various international locations. The PSI/PCI, Inc. training is recognized by federal agencies, international governments, the U.S. Military, scuba instructors, fire industry associations, and cylinder manufactures including Luxfer, Catalina, Pressed Steel Tanks, Structural Composites Inc, and Worthington.

PSI/PCI, Inc. visual inspector courses 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.

PSI/PCI continues today with Bill High as President and Mark Gresham as General Manager and CEO. Mark apprenticed with Bill for over 12 years and is widely considered the world's foremost authority on cylinder inspection requirements since Bill's "semi" retirement. He teaches worldwide and can be counted on by PSI/PCI Inspectors to provide on the spot support with questions and consultations. He continues to work with the governing authorities and cylinder manufacturers to stay up to date and provide professional consultation with regard to high pressure cylinders. Mark is one of the strongest advocates for high pressure cylinder safety and training in the world today.
