I was wondering if you could tell me how dangerous it is for pressure treated wood to be used indoors. I developed breathing problems after construction was done in my place of work. Pressure treated wood was used in the server closet next to my desk( in my work space) I developed respiratory problems during the construction) I realized that pressure treated wood was used. I have been very sick. I would appreciate any information that you could give me. I am seeing an occupational doctor.
