Special Operations – OPS for ERDI

After the basic induction, ERDI-I you can choose your level of interest.

Are you comfortable in small spaces? Then the confined operations (OPS) might be something for you. The low visibility diving, contaminated water, river rapids are  some of the specialty operations that are not only exciting to learn, they give the public safety diver and the team extra flexibility and a wider range of expertise. 

Some employers or intervention teams can dictate specific OPS before the supervisor will allow you to get in the water. OPS can be taken as a stand alone or in combination with one of the ERD levels. Full face mask and Dry suit are often run in conjunction with ERD level I diver, as it sets the stage for future Public Safety Diver training.

Confined spaces is another level, that can be combined with ERD level II diver. 



Contaminated water OPS

The name says it, diving in contaminated water, which is not safe for human contact. This may vary from human or animal waste, oil or solvents floating on the water or, cyanobacteria. The PSD that has to immerse himself in questionable water has to be covered from head to toe in order to avoid any contact with water. This can be quite comfortable in cold waters, as cover means insulation. In warm waters it can be very hot and exhausting. A good dive team will assure the diver waiting to get in the water stays comfortable and cool. 

Rubber suit, full face mask or Helmet and an umbilical ensure the diver stays clean and safe from any water contamination. The course informs the diver about contamination hazards and ways to clean equipment and work in a HAZMAT team.

The contaminated water diver course trains the candidate how to prepare to enter contaminated water, what to do once out of the water and proper, cleaning and storage of the divers’ personal protection equipment Divers should prepare to spend long hours in their PPE’s and focus on proper cleaning and decontamination of all equipment. The contaminated water OPS is one of the most challenging public safety diver training programs.

Candidates need to be at least 18 years of age and hold a certificate as public safety diver from a recognized agency. A CPR, first aid and oxygen certification are required. The candidates furthermore need to show proof of a minimum of 10 logged PSD dives. Watermanship and rescue skills are tested. Each participant will rotate through as primary diver, tender and as part of the decontamination team. This course takes 2-3 days to a maximum depth of 15m/45ft, no staged decompression is allowed



Drysuit Ops

What seems natural in northern waters may seem a bit over the top in southern countries. But all divers agree; a dry suit can be worn any time anywhere. Dry suits offer a wide range of thermal protection, back up buoyancy and protection against contaminated water.

The PSD dry suit dover course differs from the standard recreational dry suit course in that the diver has assistance in gearing up but loses dexterity because of the dry gloves. Dry suit for PSD is also heavier, mostly rubber than membrane dry suits. 

Upon certification, the candidate is able to safely dive, maintain and operate their dry suit, operating as a team member during public safety diving activities

During special occasions, the public safety diver may be asked to conduct missions during the night.  

The ERDI Night Ops Component is designed to develop the knowledge and skills necessary for night operations in emergency response diving such as scene setup, safety protocols.

The objective is to make the candidate comfortable with use of dive lights, night diving techniques, navigation and tending procedures. This course furthermore applies for diving in low or zero visibility such as waste water canals, sewage, drains or the pond in your backyard.

Full Face mask ops

Diving in unknown bodies of water has inherent risks. Even though the water may seem crystal clear, it can contain a multitude of viruses and bacteria. Hence the PSD divers’ face should be covered by a full-face mask. Full Face masks (FFM) have had little use in the recreational diving world.

Public Safety Divers rarely dive without the face or the full head covered, commercial divers, scientific divers, military divers. The benefits are clear;

-Protection against ingestion or exposure to contaminated water

-Thermal protection in cold waters

-Option for communication

-Option to defog the mask without taking it off

-Added safety; if the diver falls unconscious, the chance that he/she loses his regulator is realistic. The FFM keeps the unconscious divers’ airways clear of water whilst he/she is being pulled in via the tether.

The full-face mask course trains the candidate in the use and maintenance of most full face masks. Proper positioning, assisting and emergency scenarios are discussed and trained specifically for emergency response diving. 

What’s in it for you and your team?

  • Regulated training that involved team members in understanding functions and benefits of a full face mask
  • The ability to have each team member comfortable with full face masks diving operations
  • The ability to have each team member understands the advantages of full face mask diving operations

Upon certification you will be able to operate as a diver In open water , using FFM or as Tender in assisting the Divers to gear up.

Topics: Environmental issues | Nuclear, Biological and chemical hazards | Dangers to Diver, scene, team | Suit Permeation | Full Face mask Types & Techniques | Communication | Maintenance | Skills | Adjusting FFM | Communications | Equalisation | Flooded Mask | Mask removal | Gas depletion | Switch to backup mask |

Prerequisites: Basic Public safety diver(can be combined) | CPR and first aid certification | oxygen provider certification | Minimum 18years

Duration: The course takes 2 days

Diver Equipment: Wetsuit or dry suit | Full Face mask | Gas switching block | Technical diver harness with buoyancy control device | Single tank with pony bottle | Dual regulators | tether

Who can enter

Candidates need to be at least 18 years old and public safety diver from a recognized agency. Furthermore, a recent first aid and oxygen provision certification is required. The course provides a hands-on workshop with a variety of full face masks. The skills are practiced during both confined and open water dives whilst attached to a tether. The course lets the candidates rotate through every role as a team, giving experience in all facets of FFM diving.

The course takes 2 days and dives are to a maximum depth of 18m/60ft. This course can be combined with ERD I diver course



Helmet Diving OPS

There are a multitude of scenario’s that dictate the use of a surface supplied helmet for the public safety diver; High risk of contamination, where the dry suit is attached to the helmet. High risk of heavy objects where head protection is needed. The benefits are clear;

  • Protection against ingestion or exposure to contaminated water
  • Thermal protection in cold waters
  • Communication
  • Option to defog the mask without taking it off
  • Added safety; if the diver falls unconscious, the chance that he/she loses his regulator is realistic. The Helmet keeps the unconscious divers’ airways clear of water whilst he/she is being pulled in via the tether.

The Surface supplied Helmet course trains the candidate in the use and maintenance of a Kirby Morgan® Helmet. Proper positioning, assisting and emergency scenarios are discussed and trained specifically for emergency response diving. 

Upon certification you will be able to operate as a diver In open water , using a Helmet or as Tender in assisting the Divers to gear up.
