• Description:
  Aerosol concentrations were highest in the transfer and egg breaking rooms and in the two powdered egg packaging areas The aerosol in the transfer rooms consisted of an egg mist or a water mist that may be contaminated with egg products. In the transfer area, this aerosol arises from a poorly ventilated egg washer. Recycle of the wash water (which was observed to be heavily contaminated with broken eggs) could result in high exposure to egg protein. Improved washer ventilation should minimize the escape of this aerosol. In the egg breaking area, the mist arises from the use of compressed air to remove egg yolks, egg shells, and egg debris from the egg breaking machines. A program of minimizing compressed air pressure and installation of local exhaust of the egg breaking machines will minimize the release of egg-containing aerosols. Installation of albumen recovery devices may eliminate the need for local exhaust of the breaking machines. The dried egg processing areas (spray dryer, sifter, auger, hopper) appeared relatively dust free. Poor process layout, package selection, and job design resulted in potentially high egg dust exposures in the packaging of the powdered egg product. Improving the packaging process should reduce exposure to egg dust as well as increase employee productivity. The greatest number of workers potentially exposed to the egg-containing aerosols are located in the transfer and egg breaking rooms. Immediate improvement in working conditions in these areas can he achieved by increasing the fresh air supply in the egg breaking room from the present 4,000 cfm to the design condition of 10,000 cfm. This in effect will halve the aerosol concentrations in the egg breaking room and (since the only air supply is through the transfer windows) the transfer room.
