By way of providing background info for everyone, NIOSH has published a series of excellent guidance publications on nanotechnology that can be found here:


NIOSH’s Current Intelligence Bulletin 63: Occupational Exposure to Titanium Dioxide and the Current Intelligence Bulletin 65: Occupational Exposure to Carbon Nanotubes and Nanofibers explains their rationale for establishing an REL for nano TiO2 of 0.3 milligrams per cubic meter (mg/m3) and for CNT of 1.0 micrograms per cubic meter (=ECg/m3).  OSHA’s webpage on nanotechnology provides a listing of current OSHA standards that may apply to nano in the workplace at:   and OSHA recommends the RELs for TiO2 and CNT defined in the NIOSH CIBs and provides guidance on safe handling in their Fact Sheet: Working Safely with Nanomaterials which can be found at:


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



The recent Fiberdome Settlement Affirming  the validity of a General Duty Clause citation for exposures below OSHA PEL raises the possibility of OSHA action against a firms using NM producer who aren’t adhering to the RELs.   This settlement is discusses by the American Society of Safety Engineers at
