Semmco EEBD - Emergency Escape Breathing Device
The Semmco EEBD is a self-contained short duration oxygen (O2) re-breather that provides a supply of oxygen so that the wearer can breathe freely in a contaminated or oxygen deficient environment.
There are two versions:
- 15 minute duration for military, marine and offshore applications
- 20 minute duration for industrial applications
Regardless of the version, the Semmco EEBD uses the same system to generate a breathable atmosphere for the wearer during their escape. Initially, as the EEBD is pulled from its carry case, a starter system provides oxygen for the user’s first breath. As the user exhales into the bag, moisture from their exhaled breath passes into a canister containing KO2 (potassium superoxide). The CO2 from the wearers exhaled breath is absorbed by the KO2 that then liberates oxygen. Oxygen continues to be generated while the EEBD is being used and, depending on the version deployed, will last for 15 or 20 minutes.
The Semmco EEBD can be stored for up to 15 years but during its life, visual checks must be carried out on a regular basis.
