Contaminated Water Diving

Course Description

Contaminated Water Diving

This course is designed for a minimum of a five person dive team, either using dry suits with Magnum Rubber Hoods for full face masks or dry suits with Kirby Morgan neck dam lock in yokes with helmets. This will give the diver total encapsulation inside the helmet and dry suit.

The KM37, KM37SS, and KM 97 with the 350 or 455 Regulator can be used for contaminated water as all these helmets have a Quad Valve Exhaust Systems. This course will teach your team the proper procedures for diving in Chemical/Biological environments. Decontamination using the Macaw® backpack (CAFP) compressed air foam system and Easy DECON DF 200 foam. Easy DECON® DF200 is an environmentally friendly, non-chlorine based formula registered with the EPA and is completely biodegradable. Scientifically proven to be safe to use on all types of dive gear including personal protective gear, rubber, nylon, plastics, metal and fabrics. The course will take you through decontamination station set up, personal protective equipment, dressing the diver and stand-by diver. It will show you how to leak test divers and equipment. Entry and exit water procedures, start of decontamination process. Decontamination of diver and equipment as the diver exit the water and removal of contamination waste.

On completion of the course you will receive a certificate from Kirby Morgan Pro Dive Center for Contaminated Water diving using “Surface Supplied” dry suit full face mask and lock in Helmet neck dam. This training will parallel portions of the ACDI Contaminated Water Diving Operations. OSHA 29 CFR 1910.120 app E – H, and Intergard Easy DECON® DF 200.

Course Objective

  1. Explain why Surface Supplied Diving is different from Contaminated Water Diving using surface supplied Equipment. Differences between equipment and safety procedures.
  2. Demonstrate the set-up, safe operation and emergency procedures, when using the KMACS-5 air manifold in a contaminated environment. Explain the proper procedures for setting up the umbilical, helmet and full face masks.
  3. Demonstrate the proper donning and removable of the helmet and mask in a contaminated environment. Demonstrate the proper safety procedures for emergency out of air and loss of communication drills.
  4. Explain the correct protective equipment for class A, B, C, D. topside personnel
  5. Demonstrate proper procedures for donning dry suit, Pre dive checks, in water procedures and exiting water in a contaminate environment.
  6. Explain the different types of weight system and which are best for contaminated diving.
  7. Demonstrated proper wearing of the diver carried “bail-out” system, and the amount of gas in the bail-out needed for the depth of the plan dive.
  8. Explain the cause, prevention, and first aid for heat and cold problems related toHeat Exhausting, Heat Stroke, and Hypothermia in Surface Supplied Contaminated Water Diving System.
  9. Be able to operate and maintain all related surface supplied diving apparatus, support equipment and life support equipment.
  10. Explain the different “Site Evaluation: to dive or not to dive.
  11. Demonstrate maintenance and repair of the dry suit.
  12. Demonstrate proper procedures for disposal of hazard material.
  13. Demonstrate proper operations of the MaCaw (CAFS), and different nozzles.


On completion of this course the students will receive a Certificate of Completion for 32 hours of training in Decontamination Surface Supplied Contaminated Water Diving using neck dam lock in yokes, air manifold operations, helmet operations, PPE safety and decontamination procedures, loss of gas emergencies, diver and topside personnel heat related problem knowledge of diving physics, safe operations and emergency.


On completion of this course the student will receive a Certificate of Completion on the Safety, Care, Handling, and Troubleshooting of the Macaw backpack (CAFS) “compressed air foam system, using the Easy DECON® DF200 foam.

Target Audience

This course is intended for Military, Law Enforcement, Fire Service, Scientific and Engineer divers trained in the use of Surface Supplied Diving equipment with unlimited air supply and communications from the surface, and trained in dry suit diving.

Course Duration

32 hours - four 8 hour days


  1. A member of the Military, Law Enforcement, Fire Rescue, Scientific and/or Engineer Divers.
  2. Up to date diving physical
  3. Dive certification from a nationally recognized organization.
  4. Certification from a Surface Supplied Diving course.
  5. Train and certify in Dry Suit Diving


This course requires a minimum of five divers. If you have five or more divers we can set up a date for training at your convenience. A neighboring dive team can be used to make the five man dive team. Mutual aid will benefit both dive teams down the road.
