INTRODUCTION
This manual describes the specifications of the Ocenco EBA-75 and explains the proper use of the
unit. This manual also identifies key components and their functions. It demonstrates the proper
procedures for donning and using the Ocenco EBA-75 and the procedures to be followed in
performing daily and 90-day inspections.
GENERAL INFORMATION
The EBA-75 has been approved by MSHA/NIOSH under 42 CFR 84 as a Capacity 3, Closed-Circuit
Escape Respirator (CCER).
Similarly, the EBA-75 has the ability to provide a person with up to 6.5 hours of oxygen if he remains
at rest and follows the procedures necessary for maximum conservation of oxygen as explained in the
section titled Instructions for Use for User at Rest.
Because the EBA-75 is a life-saving escape device, each person using the unit should:
1) Be thoroughly familiar with and trained in the procedures for donning, wearing, and inspecting the
unit as explained in the Instructions for Use section on page 5 and the Inspection and
Maintenance section on page 6.
2) Avoid physical abuse to the unit.
3) Follow all NIOSH and MSHA recommendations regarding the use of self-contained self-rescuers.
WARNING
The EBA-75 was designed and approved solely as an exit or escape device. The unit is not intended
or approved as an entry and rescue breathing apparatus. Furthermore, the unit was not designed or
approved for fire fighting or underwater breathing.
SYSTEM DESCRIPTION & OPERATION
The EBA-75 is a closed circuit self-contained self-rescue device designed to be wearable with an
additional protected harness for shoulder support. The unit is housed in a rugged transparent
polycarbonate case to permit rapid, easy visual inspection of all components and to give each user
greater confidence and familiarity in using the system.
The EBA-75 system consists of two simple sub-systems:
1) The compressed oxygen supply circuit, and
2) The closed breathing circuit.
The following descriptions refer to the included EBA-75 functional diagram shown on the next page.
