Genuine question: Am I in danger?

Genuine question for the trades folk out there. My job has had me working in this attic with no ppe or ventilation all day. We don’t normally do this kind of work so our company has never had to provide ventilators or gloves. I was told it’d be ok, but now my skin itches and I have an itchy throat. Can anyone identify this insulation? There were a lot of particulates floating around but I couldn’t get a picture. Am I in danger?
