OPITO Compressed Air Emergency Breathing System (CA-EBS) delivered in conjunction with TBOSIET / THUET / TFOET

ca ebs tropical

The Compressed Air Emergency Breathing System (CA-EBS) training is designed to complement offshore safety and emergency response training for personnel travelling to an offshore oil and gas installation by helicopter (in a warm water tropical environment) when issued with a Compressed Air Emergency Breathing System (CA-EBS). Therefore, the additional CA-EBS training must be undertaken together with the Tropical BOSIET, Tropical HUET or Tropical FOET and cannot be delivered as a stand-alone course.


Personnel travelling to an offshore oil and gas installation by helicopter (in a warm water tropical environment) who require additional training in a Compressed Air Emergency Breathing System (CA-EBS) will complete this training delivered in conjunction with either the TBOSIET, THUET or TFOET course.

The objectives of the additional CA-EBS training delivered in conjunction with the TBOSIET, THUET or TFOET programs are to - Ensure delegates are familiar with the use of the Compressed Air Emergency Breathing System (CA-EBS) & Ensure that delegates understand their basic emergency response actions during a helicopter emergency using the CA-EBS

  • Duration: Approx. 2 hours
  • Validity: 4 years
  • Medical Requirement: Offshore medical certificate or medical certificate from the company
  • Pre-requisites: Nil

Use of Compressed Air Emergency Breathing System (CA-EBS)

  • The principles of compressed air emergency breathing systems (CA-EBS)
  • The principles of other typical emergency breathing systems (EBS) used in the oil and gas industry (i.e. re-breather systems)
  • The components and elements of the CA-EBS
  • The operation of the compressed air EBS equipment in conjunction with other survival equipment
  • The hazards associated with compressed air EBS
  • The pre-donning checks on the life jacket and compressed air EBS
  • How to don the life jacket complete with compressed air EBS
  • Deployment of CA-EBS

Practical Helicopter Escape

  • Donning of an aviation lifejacket, compressed air emergency breathing system (CAEBS) equipment and conducting integrity checks of the CA-EBS equipment, including buddy checks
  • Deploying (left and right hand) and breathing from CA-EBS equipment at atmospheric pressure in dry conditions
  • Following instruction from the crew, location of CA-EBS equipment and evacuation from a helicopter using a nominated exit, following a controlled emergency descent to a dry landing (conducted in helicopter simulator at poolside on dry land)
  • Actions to be taken in preparing for an in-water ditching including location of exit, deploying and breathing from CA-EBS equipment at atmospheric pressure in dry conditions (conducted in helicopter simulator at poolside on dry land)

CA-EBS Training (In-Water)

  • Deploying CA-EBS (above the water surface) and breathing from the CA-EBS in a pool, face down in shallow water (at a maximum depth of 0.7m, measured at the chest)
  • Deploying CA-EBS (below the water surface, face down in a pool in shallow water) and clearing the mouthpiece by exhaling under the water surface (at a maximum depth of 0.7m, measured at the chest)
  • Deploying CA-EBS (below the water surface, face down in a pool in shallow water, using opposite hand to previous exercise) and clearing with purge button under the water surface (at a maximum depth of 0.7m, measured at the chest)
  • Deploying CA-EBS (above water surface), in a pool and breathing from CA-EBS underwater in a vertical position (at a maximum depth of 0.7m, measured at the chest)
  • Deploying CA-EBS (underwater), in a pool and breathing from CA-EBS underwater in a vertical position (at a maximum depth of 0.7m, measured at the chest)
  • Deploying CA-EBS (underwater), in a pool, breathing from CA-EBS underwater, and moving along a horizontal rail for a period of no less than 30 seconds, including a change in direction (at a maximum depth of 0.7m, measured at the chest).
