The following updates were made to the SAG yesterday:

• Furfuryl Alcohol by GC/FIG method NIOSH 2505, the LOQ has been lowered from 10ug to 5ug using sampling collection volume of 6-25L.  This is to meet the 2016 ACGIH Notice of Intended Changes.

• Nitrogen Dioxide by in-house method WT-SOP-14 (Colormetric) has been noted as “protect samples from light” and “ship overnight refrigerated”

• Silica, crystalline by NIOSH 7500 – al methods have been noted as the preferred method over the IR method (NIOSH 7603).

These changes are now reflected on today’s SAG (10/6/2016).
