Let me address the second issue first. Most labs have no problem currently analyzing silica down to 10ug. They would not have to lower their detection limit to meet the new standard – recommended by NIOSH and ACGIH at 50ug/m3.If the accuracy of the method is ok for the current PEL - then it would be fine for the proposed PEL. Sampling at 1.7LPM for 8 hours would give you a detection limit of 12 ug/m3– well below the 50ug/m3.
As for the first part, as a Health & Safety Professional, how can you ignore the fact that exposing workers to levels of silica at the current allowable limit will cause numerous cases of silicosis. I do not have the numbers, but I am sure someone can find them to support this. Is the tradeoff of human life worth the revenue savings?
I say no.
