What is BS EN 17199‑4 - Small rotating drum method about?
Airborne NOAA and other respirable particles released during handling and transportation of bulk materials is an important consideration for workers’ exposure. BS EN 17199 discusses workplace exposure to respirable particles. BS EN 17199‑4 is the fourth part of the multi-series on workplace exposure, and describes the small rotating drum method for measuring and characterizing the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles, under standard and reproducible conditions.
BS EN 17199‑4 specifies the selection of instruments and devices and the procedures for calculating and presenting the results. BS EN 17199‑4 gives guidelines on the evaluation and reporting of the data. BS EN 17199‑4 is applicable to the testing of a wide range of bulk materials including powders, granules, or pellets containing or releasing respirable NOAA or other respirable particles in either unbound, bound uncoated, or coated forms.
Who is BS EN 17199‑4 - Small rotating drum method for?
BS EN 17199‑4 on the small rotating drum method is useful for:
- Manufacturers of products that release respirable particles
- Health and safety inspectors
- Regulatory bodies
- Quality control personnel
- Occupational hygienists
- Personnel responsible for the welfare of employees
Why should you use BS EN 17199‑4 - Small rotating drum method?
BS EN 17199‑4 gives details on the design and operation of the small rotating drum method that can be used to measure the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles in terms of dustiness indices or emission rates. Dustiness indices, as well as particle emission rates, can be mass-based on the health-related respirable dustiness mass fraction using a cyclone for the respirable dust fraction and by number using real-time sampling of particle number concentrations.
The particle size distribution of the aerosol and the morphology and chemical composition of its particles can be used by occupational hygienists, scientists, and regulators to further characterize the aerosol in terms of particle size distribution and chemical composition. This aids you to evaluate and control the health risks of airborne dust. BS EN 17199‑4 provides you with information that helps you to assess the controls and precautions required for handling and working with the material and the effects of pre-treatment.
