Thanks for the references, Bill.  The IRSST here i n Montreal also publish some excellent references about nanoparticles: ce%28%27google_cse_cx%27%2C%24lang_id%2C%24dsr%29&cof=FORID%3A9&i e=UTF-8&q=nanoparticles

Monona,< /p>


By way of providing backgr ound info for everyone, NIOSH has published a series of excellent guidance publications on nanotechnology that can be found here: ch/pubs.html


NIOSH=A1=AFs Current Intelligence Bulletin 6 3: Occupational Exposure to Titanium Dioxide < span class="tp-label">and the Current Intelligence Bulletin 65: Oc cupational Exposure to Carbon Nanotubes and Nanofibers explains their rationale for estab lishing an REL for nano TiO2 of 0.3 milligrams per cubic meter (mg/m3) and for CNT of 1.0 micrograms per cubic meter (=A6=CCg/m3).  OSHA =A1=AFs webpage on nanotechnology provides a listing of current OSHA standa rds that may apply to nano in the workplace at:   and OSHA recommends the RELs for TiO2 and CNT defined in the NIOSH CIBs an d provides guidance on safe handling in their Fact Sheet: Working Safely with Nanomaterials which can be found at:


There are also ASTM and IS O standards on the safe handling of certain nanomaterials



The recent Fiberdome Settl ement Affirming  the validity of a General Duty Clause citation for ex posures below OSHA PEL raises the possibility of OSHA action against a firms using NM producer who are n=A1=AFt adhering to the RELs.   This settlement is discusses by the American Society of Safety Engineers at x.php/govt_affairs/fiberdome-settlement-affirms-landmark-general-duty-citat ion-for-exposures-below-osha-pel/
