• Description:
  Carbon-monoxide (630080) exposures were investigated at bridge and tunnel toll authorities, including the Port Authority of New York and New Jersey, Maryland Transportation Authority, Massachusetts Port Authority, and Massachusetts Turnpike Authority. A description of each of the facilities operated by each authority, a history of operations and changes that could affect exposure to motor vehicle exhaust, a description of the job duties performed by the workers, and a description of the present and past exposures to carbon- monoxide and other agents in motor vehicle exhaust were provided. Available information indicated that current exposures were about one third lower than exposures that occurred prior to 1970. Vehicle emissions had been reduced, and improved toll booth designs allowed better natural air circulation. In some cases, forced mechanical ventilation had been installed. Exposure criteria were lower than in the past. For most workers in tunnels and toll booths, full shift average exposures were below the OSHA permissible exposure limit of 35 parts per million. At one authority, tunnel observation booths have been replaced by remote video cameras.
