NIOSH is participating in an international
effort of research groups, government
agencies and industries seeking to
understand the health impact of
nanotechnology and how to control
potential risks. NIOSH is pursuing a
number of initiatives, including:
Studying the mechanisms leading to
nanoparticle toxicity.
Developing and testing methods to
characterize and monitor the health related
properties of nanomaterials.
Investigating nanoparticle exposure and
ways of controlling exposure in the
workplace.

This document reviews what is currently
known about nanoparticle toxicity and
control, but it is only a starting point.
The document serves as a request fromNIOSH to occupational safety and
health practitioners, researchers,
product innovators and manufacturers,
employers, workers, interest group
members, and the general public to
exchange information that will ensurethat no worker suffers material
impairment of safety or health as
nanotechnology develops. Opportunities
to provide feedback and information are
available throughout this document.

The strategic plan provides a guide for
building a research effort capable of
responding to the challenges of this
emerging technology. It represents atimely research agenda and will evolve
as new information becomes available
and a more thorough scientific
understanding about nanotechnology
develops. The strategic plan describes
a multi-dimensional research agenda. Itaddresses what NIOSH is doing
internally and externally to lead the
occupational safety and health
community collaboratively in
nanotechnology research.

National Institute for Occupational Safety & Health1) Understand and prevent work-related injuries and illnesses possiblycaused by nanoparticles / nanomaterials:
- To achieve this goal, there is a need to determine the toxicity of
nanomaterials, identify possible health effects from the early uses of thesematerials, and monitor the on-going health of individuals working with
nanomaterials.
- Research will be conducted to develop and validate methods of exposure
assessment.

- To achieve this goal, there is a need to develop and evaluate engineering
controls, personal protective equipment, and guidance on safe handling ofnanomaterials. There is also a need to identify and improve safety issues in
the workplace.
- Once adequate guidance is developed, NIOSH will disseminate the
information to a broad audience and efforts will be made to incorporate it into
training programs and existing safety and health systems.

4) Enhance global workplace safety and health through internationalcollaboration on nanotechnology:
- To achieve this goal, there is a need to grow existing national and
international partnerships and establish new partnerships to identify researchneeds, approaches, and results to ensure the safety and health of workers.
- Solid partnerships will allow for the development and dissemination of
information and education to workers and occupational health and safety
professionals.
