The Semmco Marine 15 EEBD is a self-contained, 15 minute, closed circuit oxygen re-breather that provides a supply of oxygen so that the wearer can breathe freely in a contaminated or oxygen deficient environment, ensuring a quick and safe escape.
The Semmco Marine 15 EEBD uses KO2 (potassium superoxide) to provide oxygen to the user. As the EEBD is pulled from its carry case, a starter system provides oxygen into the reservoir bag. The user places the set around their neck, if practical takes a deep breath, inserts the mouthpiece and applies the nose clip before breathing normally. As they exhale into the bag, moisture from their exhaled breath activates the KO2 that then absorbs the CO2 and liberates oxygen. The EEBD continues to generate oxygen all the time the wearer breathes, providing up to 15 minutes oxygen supply for escape and 60 minutes oxygen supply at rest.
The Marine 15 EEBD is stored in an orange, rigid case that is discarded once the set is in use. This case is designed to fit existing EEBD storage systems and a visual indicator on the storage case clearly identifies the validity of the equipment. If the indicator is blue the set is viable; if the indicator is pink there may be ingress of moisture and the equipment should be returned to Semmco LPS for inspection and recertification. Assuming the case is not damaged, the anti-tamper label and seal are still intact, the unit is within expiry date and the visual indicator is blue and not pink, the Marine 15 EEBD can be stored for up to 15 years.
The Marine 15 EEBD is extremely easy to don and practical to wear. An adjustable neck strap supports the weight of the set and an elongated tube from the mouthpiece to the top of the canister ensures the set doesn’t drag in the mouth as it is being used. The breathing bag is bright yellow and so those wearing the set can be easily identified.
At the end of the set’s life it can be returned to Semmco LPS for disposal and recycling.
