The ICC Crew today: Mark Layne, Zack Haux, Chris Soike

We started the morning by inspecting the compressors with John W. and Michael L. The ICC crew had noticed moisture in the air hoses attached to the compressors. After checking the hoses and the filters, John was convinced that the moisture was water condensate and not a threat to our work. He did suggest blowing out the lines both before the beginning and end of work each day so that will be added to the procedure. John and Michael were in agreement that work should proceed.
