Course Overview
The OPITO Dry Compressed Air Emergency Breathing System (CA-EBS) Initial Deployment Training (5904) is a short, classroom-based course designed to give offshore personnel the fundamental knowledge and skills to safely use a CA-EBS when travelling offshore by helicopter. This essential training builds learners' confidence and awareness, ensuring they can respond effectively to emergency situations during helicopter transit.
The OPITO Dry CA-EBS Initial Deployment Training (5904) course at ERGT provides personnel travelling offshore by helicopter with practical understanding of CA-EBS equipment, functions, and safe use in emergency situations. Delivered over 1.5 hours at ERGT's specialised safety training centres, this course provides learners with hands-on experience using CA-EBS equipment in controlled, dry conditions.
This course is regulated by OPITO, and on successful completion, learners will receive an OPITO-approved Dry CA-EBS Initial Deployment Training (5904) certificate, which is valid for 4 years.
Learners must hold a valid BOSIET, FOET, HUET, T-BOSIET, T-FOET, T-HUET (or industry-agreed equivalent) certificate prior to attending this course.

What to expect
Learner Support
Learner wellbeing for this course is supported through measures that recognise the physical and psychological demands of CA-EBS training in a controlled classroom environment. As the course involves hands-on practice with breathing equipment and safety-critical procedures, ERGT implements support strategies that prioritise learner safety, confidence and readiness. This ensures learners can safely participate in all practical components without compromising their wellbeing or safety.
Physical Wellbeing Support
- Trainers monitor learners during practical activities for signs of discomfort or difficulty when using CA-EBS equipment.
- Learners are instructed in correct donning procedures, breathing techniques, and equipment operation prior to practical activities.
- Learners are encouraged to disclose any physical concerns (e.g. discomfort when using breathing equipment, restricted movement, or respiratory concerns) so adjustments can be made to participation.
Psychological & Emotional Wellbeing Support
- Trainers provide clear pre-activity briefings outlining what to expect during hands-on equipment practice, including safety controls in place.
- Learners experiencing discomfort or anxiety when using CA-EBS equipment are supported through additional guidance and the opportunity to observe before participating.
- Post-activity debriefs are conducted to reinforce learning, address concerns and build confidence in safe CA-EBS use.
