["Ye, Zhenyu" <yezhenyu AT uic.edu>]

Below are the list of things I think we may want to get pre-approval and the 
responsible person. It would be good if we can collect all the info 
(material, data sheets, flammability, anything else?) by the end of this 
week. Please have the info summarized in slides/word document and upload to 
https://drupal.star.bnl.gov/STAR/event/2020/08/24/star-forward-silicon-tracker-meeting/safety-pre-approval-materials

Maowu: hybrid, T-board
Michael/Gerard: inner signal cable, connectors
Yi: flexible cooling tubs, mechanical structure, hybrid and MS gluing and 
thermal grease
Zhenyu: glue/encapsulate used for APV and silicon sensor assembly 

If I miss anything, please let me know.

Thanks,
Zhenyu

On 
https://drupal.star.bnl.gov/STAR/event/2020/08/24/star-forward-silicon-tracker-meeting/safety-pre-approval-materials
attachment you can find the IST slides for safety review that Flemming found. 
What we are trying to now is not safety review so not exactly the same.
