Requirements for Scientific Diver Certification
Requirements for Scientific Diver Certification The steps to become a Certified Scientific Diver at the University of Washington (UW) are outlined below. 1. Obtain sponsorship for scientific diving by an appropriate University department or unit. Applicants who do not have a departmental sponsor and want to learn to be scientific divers can complete the Scientific Diver Course at UW Friday Harbor Labs. This course meets the requirements for full Scientific Diver certification as outlined below, and includes research projects for students to receive dive training. 2. Read the UW Diving Safety Manual. UW divers must understand and follow the safety, procedural, and medical requirements outlined in the manual and submit a signed copy of the Dive Manual Acknowledgement form. 3. Complete and submit the Diving Registration Form to the UW Diving Safety Officer (DSO). This form must be signed by the department official sponsoring the diver (e.g., principal investigator, department chair) . Submission of this form is a onetime requirement while at the UW. The form is resubmitted if any diver information changes. 4. Complete and submit documentation of recreational SCUBA diver training to UW DSO. Diving applicants must have completed a recreational SCUBA diving training course as a pre-requisite for scientific diving certification at the UW. Recreational SCUBA diving training must be provided by a nationally recognized organization (e.g., PADI, NAUI, SSI, IANTD, TDI). 5. Obtain Diving Medical Clearance from the UW Employee Health Center. Applicants will contact the UW Employee Health Center (EHC) to obtain necessary information for completing a dive physical and for transfer of medical records. -

Diving Programs
Dive Rescue International Training Programs Training Public Safety Professionals since 1977 Dive Rescue International History Founded in 1977 by a few dedicated law enforcement officials, we have remained exclusively committed to the original intent of providing training and equipment for all public safety professionals involved in aquatic incidents. In the last 35 years we have witnessed a tremendous growth in the water rescue industry largely due to greater community involvement demanding better preparedness for aquatic emergencies. We began with only a few general programs and are now able to provide over 30 diverse and specialized programs. Our greatest asset is our extensive network of public safety professionals, some have been with us since the company’s inception 35 years ago. We can call on their expertise to instruct, develop programs or provide consultation on a virtually unlimited number of topics. Since the beginning we have been based in Fort Collins, Colorado and now have over 3,000 trainers throughout North America and the world. Visit our website at www.DiveRescueIntl.com/Corporate_Trainers for information on each of our Corporate Trainers. Mission Statement Dive Rescue International will strive to provide the most current and professional water rescue education, technical support and high quality water rescue equipment to the public safety industry. Education is a dynamic process requiring continuous re-evaluation through field-testing and input from agencies or individuals facilitating a positive impact on water rescue technology. Dive Rescue International will make its educational systems, technical assistance and equipment available to all public safety professionals who respond to water-related operations. -

8. Decompression Procedures Diver
TDI Standards and Procedures Part 2: TDI Diver Standards 8. Decompression Procedures Diver 8.1 Introduction This course examines the theory, methods and procedures of planned stage decompression diving. This program is designed as a stand-alone course or it may be taught in conjunction with TDI Advanced Nitrox, Advanced Wreck, or Full Cave Course. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45 metres / 150 feet. The most common equipment requirements, equipment set-up and decompression techniques are presented. Students are permitted to utilize enriched air nitrox (EAN) mixes or oxygen for decompression provided the gas mix is within their current certification level. 8.2 Qualifications of Graduates Upon successful completion of this course, graduates may engage in decompression diving activities without direct supervision provided: 1. The diving activities approximate those of training 2. The areas of activities approximate those of training 3. Environmental conditions approximate those of training Upon successful completion of this course, graduates are qualified to enroll in: 1. TDI Advanced Nitrox Course 2. TDI Extended Range Course 3. TDI Advanced Wreck Course 4. TDI Trimix Course 8.3 Who May Teach Any active TDI Decompression Procedures Instructor may teach this course Version 0221 67 TDI Standards and Procedures Part 2: TDI Diver Standards 8.4 Student to Instructor Ratio Academic 1.

Bill's Cave Diving Lexicon
Bill’s Cave Diving Lexicon 120 Rule: Noticing from the Navy NDL table that, for certain depths, depth + bottom time = 120 so that the NDL can be determined by subtracting the depth from 120. 200 DIN: Thread depth in a DIN valve and associated pressure (200 BAR) that can be handled. This size (7 threads) allows for a DIN to yoke conversion. 300 DIN: Thread depth in a DIN valve that provides the most secure (9 threads) connection and can withstand 300 BAR pressure. 5 nines pure: 99.999% pure, as in a gas. 50-50: Gas mix of 50% oxygen and 50% nitrogen used for decompression gas. 6351-T6 Aluminum Alloy: Alloy that has had problems with tank ruptures. Absolute Pressure: Total pressure being exerted on a diver At sea level Absolute pressure is 1 ATA and it increases by 1 ATA for each 33fsw (34ffw). ADDD (Air, Duration, Depth, Distance): Limits for dive termination acronym minimum Air volume/pressure, maximum Duration of dive, maximum Depth of dive, and maximum Distance of penetration. ADV (Automatic Deflation Valve, and Automatic Diluent Valve ): Device on a buoyancy compensator that allows for rapid air purging, and device on a rebreather that dilutes the breathing mix. AGE (Arterial Gas Embolism): A lung expansion injury. A condition in which gas bubbles enter the arterial system and cause damage by blocking blood flow to vital organs, most commonly the brain. This is generally caused by air passing through the walls of the alveoli into the bloodstream. Air: A gas mixture of Oxygen (21%), Nitrogen (78%), and other gasses (1%, Helium, Argon, etc.). -
