Your workplace should be a safe and healthy place to do your job. Your employer is obligated by law to provide you with this and if he does not, then you should know that you have rights. You also have responsibilities for your own well being as well as the co-workers that are with you.
By law, you as an employee have many rights that you might not know about. You have the right to work in a safe and healthy location that is controlled as mush as possible.
