This section will help in determining how much each of us was exposed to the toxic brew of chemicals at the Titan II nuclear Missile sites. I am going to try to put a section which will be dedicated to each group of Titan II workers such as PTS and Maintenance and Crew Members.
Calculating adjusted TLV-TWA toxic chemical exposure for Titan II Missile maintenance workers
This work is in progress. As I read the 2003, 2005 and 2011 ACGIH manual I will continue to add more information.
"ACGIH in the 2003 TLVs® and BEIs® refers to the Brief and Scala model (found in Patty’s) as a "tentative" guideline for industrial hygienist dealing with extended work shifts. The Brief and Scala model reduces exposure limits according to a reduction factor calculated by the formulas."
There are four steps to determining how much over exposed to the toxic fuels each of us were based on the DM AFB study of normal UDMH, NDMA, and Hydrazine concentrations in the silo and launch control center.
First, we must modify the 1995 UDMH 10 ppb TLV-TWA ACGIH allowed limits based on work schedule. The 10 ppb is based on a normal 8 hour work shift per day five days a week. There were very few jobs around the Titan II missiles that had that typical civilian work schedule (Bankers hours). The 10 ppb limit on Hydrazine and UDMH must be reduced according to ACGIH guidelines.
Second, we must account for the other toxic chemical TLV-TWA's and adjust their limits.
Third, we must then account for all the TLV-TWA's.
Fourth, we must figure out our actual exposure based on our travels throughout the Titan II missile Complex based on the DM Titan II complex toxic study of 1983 which was botched. See calculations.
