Heat Stress and Carbon Monoxide Exposure at Mexican Border Crossing Stations.
NIOSH 1975 Oct:19 pages
An inspection of the crossing stations for vehicular traffic from Mexico to the United States is reviewed. Susceptibility of border crossing employees to heat stress and the possible hazards involved in their exposure to carbon-monoxide (630080) (CO) from motor vehicle exhaust are discussed. The authors conclude that temperature and humidity conditions encountered at the various border crossings are not severe enough to produce serious heat stress, but that they are uncomfortable. They also conclude that excessive CO concentrations exist at several stations. They recommend improvement in the following existing applications: air movement, evaporative cooling, use of air conditioned booths, and job rotation.
