collector design Considerations
The design and construction of dust collectors, containment devices may need to address a range of potential issues; including configuration decisions to minimize material build-up, seam sealing of collectors and ducts, duct attachment and sealing techniques, and potential use of secondary monitoring filter such as HEPA filters.
In some instances, devices with special seals are required to reduce or eliminate the discharge of dust from the dust collector when transferring material to storage containers for disposal. (See customized 50 ft liner system video above.)
Pharmaceutical processes that may generate Dust
The following diagram shows pharmaceutical processes in gray that may require dust collection:
Many pharmaceutical dusts are combustible and those operations generating or handling pharmaceutical dusts can require special mitigation efforts to minimize fire and explosion risks. Standards such as NFPA 654 can provide guidance for those who generate and handle these types of dusts. See the Donaldson Dust Collectors and Combustible Dust Strategies brochure.
Pharmaceutical dusts may also have identified adverse health impacts, and special mitigation strategies may be required to limit occupational exposure below levels OSHA or other health organizations have established for these materials.
LEGISLATION (OTHER FEDERAL AND LOCAL LEGISLATION MAY APPLY)
Particulate Matter (PM):
- PM 2.5 = 15 µg/m3 (annual), and 35 µg/m3 (24-hour)
- PM 10 = 150 µg/m3 (24-hour)
