RJ,

I hope you have the MSDS for the F18 with you to take to the doctor. Yes these symptoms can be due to the inhalation of Sodium Hydroxide. The irritation to your sinus passages, throat and lung tissues can be causing the low grade fever as your body tries to combat the irritation damage. Please consult a doctor as soon as you can before you get any kind of infection in these tissues. We handle the raw material and mixed formulation all the time and we never play with even a possible exposure. We send our employees to the doc. It would be much better for him to tell you that it is just a cold. I don't want to alarm but just want you to be safe and healthy.
