Emergency Escape Breathing Device (EEBD)

There are two EEBD configurations in the US Navy: the Ocenco M-20.2 is a phase replacement to the Scott EEBD.

Ocenco M-20.2 Description

The Ocenco M-20.2 compressed oxygen EEBD will operate for 10 minutes after it is activated. It can be donned in less than 10 seconds; simply unlatch the case, pull out the unit, and insert the mouthpiece and nose clip.

The attached hood can be donned at anytime during the escape. The compressed oxygen and mouthpiece combination allows the Ocenco M-20.2 EEBD to be donned in a smoke-filled environment.


Manufacturer Information: Ocenco Incorporated www.ocenco.com

Scott Description

The Scott EEBD is a non-rechargeable self-contained breathing unit which provides the wearer with 15 minutes of oxygen for emergency escape only. It can be donned quickly by removing the unit from the vacuum bag, pulling the actuating ring and placing the hood down over the head.

Oxygen is generated by the breakdown of a sodium candle which is housed in the life support pack. A carbon dioxide scrubber, also in the life support pack, removes carbon dioxide that is exhaled by the wearer.
