YES! You may end up with the same disease that people who work in steel foundries or work for asbestos removal companies get -- emphasema, mesothelioma (cancer), lung cancer, bronchitis, pneumonia, etc. you won't get it next year, but in 20 years from now, you could be completely disabled, rolling around in a wheelchair carrying an oxygen bottle.





Turn the fan on AND wear a facemask (like doctors wear).Laser toner dust. Harmful?
yes, it is. but depends how enclosed a space you are working in. if its a big open space, dont worry much. if its the size of a dorm room, you NEED a fan. you can contract cancer, lung cancer, and all sorts of problems. *possiblity, no garuntees.* anyway, use protection whenever.
