Assessment
Step 1 Potential for nanoparticle exposure
Information gathering (desk & walkthrough survey):
- Nanomaterials involved
- Process & maintenance
- Workers tasks
- Sources of incidental/process particle emission
- Exposure controls
- Ventilation
Screening measurements
Easy-to-use instruments to identify points of particle emission
Evidence of exposure
Step 2 Basic exposure measurements
- Limited number of user-friendly instruments
- Characterization emission source during activity
- Background levels
- Sampling and chemical analysis
Concentration level significantly increased over background
Step 3 Comprehensive exposure measurements
- Collection of particles for physico-chemical characterization
- Real time measurements with sophisticated instruments (particle number, size, surface area, mass )
Take additional risk management measures to mitigate exposure (precautionary principle)
Services
