Workplace exposure - Guide for the use of direct-reading instruments for aerosol monitoring - Part 2: Evaluation of airborne particle concentrations using Optical Particle Counters
This Technical Report describes the principle underlying evaluation of one or more health related aerosol fractions using an optical particle counter and details its limits and possibilities in the field of occupational hygiene.The method complements conventional long-term aerosol particle sampling and offers possibilities of:- instantaneous (direct reading) measurement;- time-related monitoring;- investigation of space-related aerosol evolution (mapping);- assessment of particle size distribution.The method enables e.g.:- detection and relative quantification of concentration peaks due to specific operations (bagging, sanding, etc.);- identification of mos
