My daughter is ok for now. Thank you all for your prayers. Sorry it has taken so long to get back to you. I tried to post, but had problems - I could type, but the post button didn't work. Anyway, my daughter said they sheltered in place for over an hour, and the warehouse immediately turned off heat and air systems. She and her other managers handed out masks - actually they double-masked for safety, and kept everyone informed of the situation. They were finally allowed to evacuate - told to go directly to their cars and make sure recirc was on so that they didn't bring air into the cars and head home. My DD also said the day was extremely windy, but fortunately her home was upwind. She doesn't know if/when they will be allowed back into the warehouse tomorrow (this was a phone call earlier - don't know currently) She also said that all of Tucson was told to stay inside tonight to be safe.
