Clearance Asbestos Air Monitoring

Clearance asbestos air monitoring tests the air to measure the level of airborne asbestos fibers in an area following work or removal of asbestos containing materials. An area is ‘cleared’ when the level of airborne asbestos fibers is measured as being below 70 structures per millimeter squared (AHERA TEM).

For PCM sampling and analysis using NIOSH 94-113 Method 7400, the fiber concentration inside the abated regulated area, for each airborne sample,shall be less than 0.01 f/cc. The abatement inside the regulated area is considered complete when every PCM final clearance sample is below the clearance limit.


  1. there should have been some means of ancnokledwigg who was dancing in new numbers. My friend was gushing over how well Marko did with Melanie in the Broadway number and was surprised when I told her it was actually Jess. These dancers deserve at least a moment or two of audience appreciation all of them. I did like the blending of dances into a more theatrical experience, but did not like the new pair coming out before one pair finished. Again, no chance to applaud. We were smitten by Ricky and Jess, even though we went in as girl-focused favorites. Those two were phenomenal, esp. Energizer Bunny Jess. Overall, great show.
