• Description:
  In the United States, more than 5 million workers are involved in agricultural production. NIOSH has a long-standing initiative for investigation and prevention of occupational health and safety problems within the agricultural industry. A key component of this program is protecting the respiratory health of workers in the agricultural industry. Agricultural workers can be exposed to pesticides, dusts and mists, bacteria, fungi, endotoxin. Exposure to these particulates can take place within environmental tractor cabs. Cab filters are not required to meet the same testing criteria as particulate respirator filters certified under 42 CFR 84. New and used particulate filters from environmental tractor cabs have been evaluated for filter penetration as a function of particle size in the submicrometer size range of 0.03-0.4 microm. Further, the cab filter media were tested against a solid sodium chloride aerosol and/or a liquid DOP aerosol as explained in 42 CFR 84, except that flow rates were adjusted for velocity differences. The most penetrating particle size for these filters are in the range of 0.1-0.3 microm, as is the case for respirator particulate filters. The data indicate that a broad range of filters and filter combinations with highly varying efficiencies (10%-99% at submicrometer particle sizes) are used in environmental tractor cab filtration units.
