作者对喷气式飞机的加油工人进行职业性危害评价时,了解到有两名工人死在加油车内和其附近处。为此调查了飞机加油车内接触一氧化碳的情况,两次访问了某一国际机场,测定了7名加油工人个体样品中及17辆加油车驾驶室空气中一氧化碳(CO)的浓度。结果个体样品CO浓度为5.5～140 ppm,因为加油工有时在车内有时在车外工作,故CO浓度波动较大。驾驶室内CO浓度为5～300 ppm,一辆为300 ppm,两辆超过100 ppm,5辆超过50ppm,9辆小于50 ppm。上述结果表明许多加油车内工人接触CO超过了容许浓度,因为17辆受试车中有8辆的平均浓度≥50 ppm,有
When the author conducted an occupational hazard assessment of jet fueling workers, he learned that two workers died in and near the fuel tanker. To investigate the exposure to carbon monoxide in aircraft refueling vehicles, two international airport visits were conducted to determine the concentrations of carbon monoxide (CO) in the air of seven refueling workers and in the cab of a tanker truck. As a result, the CO concentration of the individual sample was 5.5 to 140 ppm, since the fuel dispenser sometimes worked in the vehicle outside the vehicle sometimes, so that the CO concentration fluctuated greatly. The CO concentration in the cab is 5 to 300 ppm, one for 300 ppm, two for more than 100 ppm, five for more than 50 ppm and nine for less than 50 ppm. The above results indicate that many refueling car workers exposed to CO exceeded the allowable concentration because eight of the 17 tested vehicles had an average concentration of ≥50 ppm, with
