What is Pre-Packing the BioPak?
Pre-Packing the BioPak refers to conducting full turn around maintenance procedures that include installing the filled oxygen cylinder and the carbon dioxide scrubbers. This procedure is explained in the Benchman Manual and will allow the BioPak to be stored in a near ready condition for up to one-year.

What are the mandatory replacement parts of the BioPak?
Unlike other respirator makes and models, the BioPak is designed with no mandatory replacement parts, with the exception of the oxygen cylinder that must be replaced every 15-years due to Government regulations.

How does one know if the proper amount of CO2 absorbent has been installed into the BioPak?
The BioPak is the only respirator that utilizes “Solid-Core” scrubber technology that eliminates the need of the user to measure and fill scrubber canisters. The proper amount of scrubber is provided to the user in single use packaging that will guaranty that the proper amount of absorbent is utilized every time.

The BioPak 240R battery removal ribbon extends outside the battery door after the battery door is installed. Is this permitted?
NO! The battery door contains a gasket to seal the interior of the battery compartment against contact with external ambient air and gasses. The presence of the ribbon underneath the gasket will provide a leak path for external gasses to enter into the battery compartment and will void the intrinsic safety of the monitor device.

What is the proper method for cleaning the BioPak with regards to BioPak disassembly?
There are two accepted methods of BioPak disassembly that the benchman is free to utilize as follows:

• No Tool Method: In this method the entire breathing loop is removed from the BioPak via the four ¼-quarter turn hand pins holding the breathing chamber in place. The facepiece is removed from the hose connection and the breathing chamber lid is removed from the main breathing chamber body. The breathing hoses and diaphragm are not removed. This leaves the benchman with the breathing loop totally intact with no loose parts other than the facepiece. The benchman would now clean and disinfect the facepiece and the breathing loop as described in the Benchman Manual. This method requires no tools but can be cumbersome and difficult to fully rinse and dry the breathing loop.
• Complete Disassembly Method: This method involves removing the entire breathing loop from the BioPak via the ¼-turn hand pins holding the breathing chamber in place. The diaphragm and breathing hoses are disconnected from the breathing chamber and the facepiece is disconnected from the breathing hoses. The benchman would now clean and disinfect the facepiece and the breathing loop as described in the Benchman Manual. This method requires the use of a single hand tool and provides for greater ease of component handling, better wetting of all components and greater ease of component rinsing and drying.

Why is the facepiece not included in turn around or long term maintenance procedures?
The facepiece is included in these procedures. The facepiece should be inspected, washed and disinfected after each use as stipulated by the turn around maintenance procedure. The facepiece should be included in the inspection of components under long term maintenance as stipulated by long term maintenance procedures.

How is it determined if the check valves of the facepiece are functioning properly?
The User Manual specifies a check valve and face seal functionality test that is to be performed each time the BioPak is donned. This test will validate check valve function as well as determine that the face seal of the facepiece is properly made on the user.

Can the same disinfectant be utilized on the BioPak as is utilized on other equipment?
The BioPak should be cleaned and disinfected according to the procedures stated in the turn around maintenance procedure using the disinfectant specified by the turn around maintenance procedure or approved by Biomarine. The use of other types of disinfectants could cause damage to the facepiece lens or attack the plastic and rubber components of the BioPak.
