NIOSH 1979 Jun; :1-7
Breathing zone and general area atmospheric samples were taken for total particulates, respirable particulates, and qualitative and quantitative inorganic analyses on March 15, 1979 at a Raven Industries (SIC-2221) facility in Parkston, South Dakota. A bulk sample of down feathers was also taken to be desorbed with organic solvent and analyzed for the presence of organic substances. The sampling was prompted by a request from a management representative regarding employee exposure to down feathers at the facility. Five employees were given nondirected medical interviews; two of these employees had experienced problems that they attributed to their exposure to residual down feathers. Results for total particulates (0.04 to 1.6 milligrams per cubic meter of air) and respirable particulates (1.6 to 3.2 milligrams per cubic meter of air) were below threshold limit values (10 and 5 milligrams per cubic meter of air, respectively) for these particulates. Qualitative analysis revealed no inorganic disinfecting agents or organic deodorizers. Installation of local exhaust ventilation designed to exhaust from the point of generation is recommended if other workers in or near the down insertion room become sensitive to down feathers. If respirators are used as a means of control, it is recommended that the respiratory program be modified to assure that it is in compliance with OSHA General Industry Standards.
