Introduction
This manual and the enclosed video are tools for conducting training classes in the proper use and
inspection of the Ocenco M-20.2 EEBD. An M-20.2T training model is available for practicing the
opening, and donning of the M-20.2 EEBD.
The Ocenco M-20.2 EEBD can be belt worn or stored in a wall bracket. The Ocenco M-20.2 EEBD is a
self-contained, compressed oxygen, emergency escape breathing device (EEBD). The Ocenco M-20.2
EEBD instantly provides breathable air, independent of the surrounding atmosphere, to a person escaping
from toxic gas or an oxygen deficient atmosphere.
The Ocenco M-20.2 EEBD meets the
International Convention For The Safety Of Life At Sea, SOLAS
1974, Chapter II-2
requirements for Emergency Escape Breathing Devices. The Ocenco M-20.2 EEBD
also meets the
International Code For The Construction Of Ships Carrying Dangerous Chemicals In
Bulk (IBC code)
and the
International Code For The Construction Of Ships Carrying Liquefied Gases
In Bulk (IGC code)
requirements for a self-contained breathing apparatus with a normal duration of service
of 15 minutes in maritime applications.
This Manual provides information on both the Ocenco M-20.2 EEBD and the Ocenco M-20.2T Training
Model. The Instructor should cover the following topics:
(1)
How the M-20.2 EEBD works
(2)
How to don the M-20.2 EEBD
(3)
How to inspect the M-20.2 EEBD
(4)
How to care for the M-20.2 EEBD
(5)
When to don the M-20.2 EEBD
(6)
location of M-20.2 EEBDs (see ships fire control plan)

2.1.
How the M-20.2 EEBD Works
Oxygen automatically flows from the cylinder to the breathing bag when the device is pulled
from its clear base.
During inhalation, and whenever the bag flattens, the oxygen regulator increases the oxygen flow
into the breathing bag.
During inhalation and exhalation, the lithium hydroxide scrubber absorbs carbon dioxide.
During inhalation, oxygen passes from the breathing bag through the scrubber and into the
mouthpiece.
During very low work rates, such as when the user is at rest waiting rescue, the oxygen regulator
supplies more oxygen than the user can consume. When this occurs, the excess gas automatically
vents through the relief valve.
The M-20.2 EEBD operates automatically. This includes the starting of the oxygen flow, the
increased oxygen flow rate during high work periods, and the venting of excess gas through the
relief valve.
