Ensure that the personnel gains the required knowledge and understanding of the particular hazards and properties of a Compressed Air Emergency Breathing System (CA-EBS). The course includes theoretical and practical lessons. The course is in Italian and, on request, in English.

Theoretical aspects:

  • CA-EBS principles of use:

Differences between a re-breather system and a compressed air system

  • Advantages of an A-category EBS:
  • Opening rapidity
  • Underwater opening
  • Really Limited breathing resistance
  • It can be opened with only one hand
  • Reduced dead space and possibility to expel water through mouthpiece
  • Disadvantages of a compressed air EBS
  • Limited air supply
  • While ascending breath must not be held
  • Dangers related to a compressed air EBS use
  • Pulmonary extension dangers
  • Violent inspiration due to cold water ingress shock
  • Cough
  • Mouthpiece movement (accidental or intentional)
  • Air loss
  • Air exhaustion
  • CA-EBS components and elements
  • Mouthpiece
  • Little tank
  • Demand valve
  • Pressure gauge
  • Tank valve (if provided)
  • Valve Status indicator(open-closed) (if provided)
  • Purge button
  • Nose-plug (if provided)
  • Charge point
  • Operations with EBS together with other emergency equipment
  • Life jacket
  • Survival suit (right size)
  • PLB
  • Operations with Life jacket
  • Importance to remove mouthpiece and nose-plug before inflation
  • Inflation systems
  • Never inflate life jackets inside the aircraft
  • PLB activation
  • Strobe light and fixed light activation
  • Whistle use and lanyard (link to another life jacket)
  • Inflation hose and pressure valve
  • Positioning of splash protection visor


Practical session:

  • Compressed air EBS check before wearing and use manometer reading
  • Correct working of the valve status indicator
  • Tank valve (if provided)
  • How to wear a life jacket with a compressed air EBS
  • Make sure the belt (if provided) is not twisted
  • Life jacket fastening
  • Belt adjustment
  • Make sure that the belt is correctly fastened (even the thigh strap)
  • Make sure that the EBS mouthpiece is correctly positioned
  • After wearing the equipment check your partner
  • Emergency CA-EBS opening:
  • Device locating
  • Rapid opening
  • Approaching to the face, wearing mouthpiece and nose-plug, sealing the mouthpiece
  • Breathing normally
  • How to purge the system
  • How to locate the mouthpiece that moved
  • Breathing until the air runs out (look at the oxygen tank to see when the air is about to finish)
