Emergency Breathing Systems (EBS)

Accredited Training


Emergency breathing systems is another tool which will assist you in ditching situations. The extra minutes the purpose built compressed air bottle gives you makes it worth its weight in gold… but it may as well be made of lead if you don’t know how to use it properly and safely.

The RHO Aviation EBS course will give you the skills you need to be confident in using your Emergency Breathing System, whatever brand it is. The EBS course will teach you the dangers of breathing compressed air and how to safely avoid these dangers, how to locate and activate the device underwater with no or limited visibility… and then after all that, escape the aircraft!

If you are already equipped with EBS or are thinking of acquiring the equipment and you would like to try out the various systems on offer then our training will give you the confidence and knowledge you need to use the systems safely. It will also allow you to make an informed decision before you buy. Our EBS course can be run by itself or concurrently with a HUET course. (Please note: If you want to undertake an EBS course by itself, you must be familiar with HUET procedures i.e. you must have completed a HUET course at some time in the past.) Include the training with CRM and receive the complete safety package.

We use the Survival Egress Air (SEA) LV2 system – left – (which is used by the US Navy, US Marine Corps and US Coast Guard) and the Helicopter Aircrew Breathing Device (HABD) – below – (as used by the Australian Army) . The SEA LV2 is an excellent life saving device and is considered a 3rd generation emergency breathing system. The SEA LV2 is cosmetically similar to the HABD but its enhanced design and functionality make it a superior system to any other compressed air EBS on the market. The benefit of the LV2 is the lower volume of water to purge and the general ease of use. Also, the mouthpiece can be fitted in six different angled positions making it easier to configure for each individual.

“Use our equipment to master the skills and provide you with the knowledge you need to go shopping for your own systems”

The SEA LV2 fitted in the new EBS holster integrates well with the Switlik crew vest allowing for a comfortable easily accessible fit. Talk to RHO Aviation about your EBS solutions. We can recommend systems and deliver training packages that will integrate into your organisation seamlessly. Use our equipment to master the skills and provide you with the knowledge you need to go shopping for your own systems.

The RHO Aviation EBS course uses the specially engineered HeliPET procedural trainer for training. The HeliPET allows all axes impact scenarios, dual person configuration and cross-cockpit/cross-cabin drills as well as push out exits and hatches with jettison handles. The HeliPET is a state-of-the-art procedural trainer well suited to EBS training allowing excellent instructional functionality.

The US Coast Guard and US Navy prefer not to use HUET simulators for their EBS training, preferring a disorientation device for safety reasons. The HeliPET builds upon and enhances the benefits of this type of training. When RHO Aviation looked at supplying Helicopter Underwater Escape Training to the aviation and associated industries, we looked at various systems.


“Having that HEED III (a version of EBS) was probably the most important piece of equipment that I used that day, because it gave me three important things. It gave me confidence, time and it performed flawlessly inverted, in rough seas and jet fuel.”

– Garth J. Leesmand, Helicopter Pilot

“I had the distinct luck to be wearing an “EBS” bottle on the night that my helicopter experienced a material failure and crashed at sea. As with most pilots, I completed all training, but never expected to use your equipment because my aircraft would never fail me! I guess my luck ran out on this night. My wife and I thank God for the HEED bottle. I have no doubt that without EBS this letter would have never been written! God Bless.”
