Evaluation of Dust Hazards Post Office Annex Cincinnati, Ohio.
NIOSH 1967 Feb:7 pages
Survey for airborne dust at a post office facility revealed that most of the dust appeared to be emitted from the mail bags. The local exhaust in the building did not appear to be effective in the collection of dust, most dust being located above the workmen rather than near the dust source or points of mail handling. The quantity of air moving into the ventilation system at the ventilation points was very low. Recommendations are made for improving the conditions.
