Section I. GENERAL INFORMATION
1-1. SCOPE. This manual contains operating and unit maintenance instructions for the Self-Contained, Toxic
Environment, Protective Outfit-Interim (STEPO-I). The STEPO-I is designed for use with a remote air source using a
pass through connection in the encapsulating protective suit for a tether line (maximum of 300 feet) hook up. It may also
be used independently with the rebreather system. Both modes of operation are for use in immediate danger to life and
health (I DLH) concentrations of class G, H and V agent environments. The STEPO-I is not approved for use in
temperatures below +32°F (0°C) in the tether mode and +15°F (-9. 44°C) in the rebreather system mode. STEPO-I
authorized weartime (stay time) with cooling vest at ambient temperatures at or above 850 F (29. 44°C) is 45 minutes.
Ambient temperatures below 85°F (29. 44°C) is 2 hours. Maintenance of the emergency breathing apparatus (EBA) is to
be performed only by certified maintainers. All other STEPO-I components shall be maintained only by trained
maintenance personnel. The operator is not authorized to perform any maintenance specified in Chapter 3 of this
publication. Authorized equipment and its location is shown in paragraph 1-9, Location and Description of Major
Components.
