USER MANUAL

Oxygen Statement

In diving operations, the use of oxygen is essential for the human metabolism.  

In addition, oxygen concentration levels greater than in air, can improve safety, 

especially but not only, by lowering the risk for DCS and Nitrogen narcosis.

The Poseidon Xstream Deco/Oxygen is approved for use with gaseous oxygen up to 

99.95 % purity at maximum 300 bar supply pressure and a maximum gas temperature 

of 60˚C. The Poseidon Xstream Duration90/Duration/Duration EN 144-3 is also 

approved for use with gaseous oxygen up to 99,95 % purity at maximum 300 bar 

supply pressure and a maximum gas temperature of 60˚C.

Using gaseous mixtures containing oxygen at high pressure always presents a certain 

level of risk for equipment failure due to combustion. Greater concentration oxygen, 

greater pressure, greater temperature, respectively represents factors that contributes 

to increase the mentioned risk. Therefore, Poseidon has taken every precaution using 

“state of the art” technology, expertise, industrial standards, and knowledge to lower 

the risk as far as possible. Both Xstream Deco / Oxygen and Xstream Duration are 

engineered for oxygen use, assembled and cleaned in a clean room environment, 

made up by materials chosen to expose lowest possible risk x failure-effect product, 

and are tested and approved for oxygen use. 

It is strictly prohibited to use the Poseidon Xstream Oxygen/ Deco/Duration/Duration90 

with oxygen (ref. “definitions”) without being fully trained and certified in the use of 

oxygen by a recognised training agency. Failure to have such training and certification 

could lead to death or serious personal injury.

It is likewise absolutely essential that the end user strictly follows the mandatory 

guidelines given in the users manual for the Xstream models. Regular maintenance, 

servicing and cleaning is a prerequisite for keeping the risk as low as possible. Servicing 

and cleaning must be carried out by an authorised oxygen service dealer. Poseidon 

has developed and verified a servicing and cleaning method, which guarantee 

acceptable levels of contaminations. Poseidon can not be held responsible for the 

effects of other un-verified cleaning and servicing methods.

Failure to adhere to these mandatory requirements transfers the responsibility to the 

owner. 

Poseidon will continue to develop products and components which further readuses 

the risks involved with oxygen use. Releasing such products and components is not 

an admittance that previously released items must be recalled. It is in everyone’s 

interest to always strive for lowering risks.
