• Description:
  In response to a request from the Safety and Training Supervisor of the Lehigh Portland Cement Company (SIC-3241), Union Bridge, Maryland, an investigation was made to identify a bleach odor inside one of the cement kilns. Maintenance personnel working inside the kiln at times of shutdown reported respiratory and eye irritation. Personal breathing zone samples were collected during the next shut down while workers were removing and replacing 25 feet of refractory brick at the front end of the kiln. Area samples were collected for chlorine (7782505), inorganic acids, sulfur-dioxide (7446095), oxides of nitrogen, ozone (10028156), respirable dust, total and inhaled dusts. Ozone was detected at 0.6 to 0.7 part per million (ppm) when conditions during previous episodes were recreated. Ozone was detected through a portal at the back end of the kiln at well over 0.7ppm. A direct reading meter revealed a concentration of 4.5ppm. When the induced draft fan was turned off, ozone from an electrostatic precipitator apparently back drafted into the kiln. The authors conclude that the eye and respiratory irritation were a result of ozone exposure.
