1. On 14 October 2021 Industrial Hygiene sampled for Hexavalent Chromium (Cr+6), Lead (Pb), and Asbestos in building 2049. Samples were taken in various locations and sent to a lab for analysis. The sampling event was conducted as a follow up to samples that were taken on 14 and 15 September 2021. (see previous report dated 29 September 2021).

2. Results:

a. Hexavalent Chromium Wipes Per OSHA Directive number CPL 02-02-074, a wipe sample is collected to determine whether the contaminant is in fact present, (limit of detection), not to measure against any quantitative threshold of dust loading. The limit of detection the lab used is 0.030 microgram per wipe. All 7 wipe samples taken were above the limit of detection.

b. Lead Wipes According to the U.S. Department of Housing and Urban Development HUD (EPA), wipe samples in a 100 centimeter square area (wiped area) should not exceed 6.7 micrograms. One wipe sample was above this limit.

c. Asbestos (Bulk) The asbestos samples were analyzed to determine the presence of asbestos in the debris. Per OSHA 1910.1001 (b), Asbestos-Containing Material (ACM) means any material containing more than 1% asbestos. None of the 3 samples taken contained more than 1% asbestos. According the lab results, all 3 of the samples are labeled as TR. TR = Trace equals less than 1% asbestos.

3. The attached Sample Event Posting of the sample results should be posted for employee review.
