The World Health Assembly identified the assessment of health impacts of new technologies, work processes and products as one of the activities under the Global Plan of Action on Workers Health, adopted in 2007, and the WHO Global Network of Collaborating Centres in Occupational Health has selected manufactured nanoparticles as a key focus of their activity.
To address occupational risks of nanomaterials, WHO is developing Guidelines on "Protecting Workers from Potential Risks of Manufactured Nanomaterials" (WHO/NANOH). These Guidelines aim to facilitate improvements in occupational health and safety of workers potentially exposed to nanomaterials in a broad range of manufacturing and social environments. The guidelines will incorporate elements of risk assessment and risk management and contextual issues. They will provide recommendations to improve occupational safety and protect the health of workers using nanomaterials in all countries and especially in low and middle-income countries.
