Abstract
Survey of the health hazards resulting from accumulation of carbon- monoxide (630080) and other noxious fumes at the crossing stations for vehicular traffic from Mexico to the United States. The primary inspection areas handled as many as 2,500 cars per hour, frequently with long lines of idling cars. Readings of wet bulb and dry bulb temperature, globe thermometer temperature, and air velocity were taken to investigate the possibility of heat stress on employees. Carbon-monoxide concentrations were measured with an automatic recorder and with detector tubes. It was found that temperature and humidity conditions at the border crossing stations did not produce serious heat stress. The carbon-monoxide concentration at several stations did exceed allowable limits and at other stations these limits could be exceeded when certain wind and traffic conditions occur. Recommendations are made to alleviate the problems.
