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 ?
