    Within this section is part # ( 2 )  

    WAGD that is produced by the medical - surgical vacuum source shall be maintained below the level of oxidizers by 23.6 percent.

     

    So, the question of the day is how is this done ?

     

    1) a monitor on the exhaust line (if so, shall it have a local alarm)

     

    2) ramdon sampling by staff    (if so, how often)

     

    3) once a year at time of the annual (is so, what time of day)

     

    And after all this, what is to happen if it's over 23.6 percent ?

     With that code they expect the manufacturers to design their equipment to dilute the waste anesthetic gases to meet NFPA. 

     The same as they expect someone who makes ball valves or alarms to meet the NFPA criteria's if they wish to sell them in the medical industry.

    Who is they ?

    Why not put this task, on the people that are producing the WAGD ?

    What about alarms ?

    What about guidelines for the facilities, if the oxidizer are over 23.6%.

    What about existing system ?

    Are they to be shutdown, turn off or replaced?

    Has there ever been any talk of requiring manufacturers to include a local alarm for oxidizer content on their packages? 

     

    We've been asked to measure this content at facilities still using old, oil-flooded pumps for WAGD (I know of one that caught fire after years without oil/filter maintenance and a failed high temp shutdown), but in my opinion there are too many variables to provide a reliable spot check of this.

     I know of none and it would be expensive to monitor.   It would be cheaper for the facility to replace their vacuum pumps.
