Registration is open for the U.S. National Nanotechnology Initiative’s (NNI) March 23, 2021, webinar on “What We Know About NanoEHS:  Human Exposure.”  The webinar will feature experts from diverse disciplines to share their perspectives on key findings in quantifying and assessing the effects of human exposure to nanomaterials.  Keana Scott, Ph.D., Physical Scientist,

The Occupational Safety and Health Administration (OSHA) is scheduled to publish a notice of proposed rulemaking (NPRM) on February 16, 2021, that would modify the Hazard Communication Standard (HCS) to conform to the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Revision 7 “to address issues that arose during the

On January 5, 2021, the National Institute for Occupational Safety and Health (NIOSH) posted a Science Blog item entitled “Understanding the Broad Class of Carbon Nanotubes and Nanofibers (CNT/F) Used or Produced in U.S. Facilities.”  The item summarizes a recently published article in the journal Particle and Fibre Toxicology, “Physicochemical characterization

On June 25, 2020, the National Institute for Occupational Safety and Health (NIOSH) published a Nanotechnology Research Center (NTRC) Program Performance One-Pager (PPOP).  NTRC conducts research to understand the potential effects on human health of exposure to engineered nanomaterials (ENM) and develops methods to control or eliminate exposures.  According to the PPOP, NTRC’s accomplishments include

On June 30, 2020, from 9:00 a.m.-10:30 a.m. (EDT), the European Union (EU) NanoSafety Cluster will hold a webinar on “Immune response from occupational exposure to CNTs and nanofibres.”  The following speakers will discuss work at the U.S. Centers for Disease Control and Prevention (CDC) National Institute for Occupational Safety and Health

The National Institute for Occupational Safety and Health (NIOSH) has posted two posters from the NIOSH Nanotechnology Research Center (NTRC) on 3D printing:  3D Printing with Filaments:  Health and Safety Questions to Ask and 3D Printing with Metal Powders:  Health and Safety Questions to Ask.  The posters provide health and safety questions with different
