Exposure of the deck crew to volatile hydrocarbon compounds and polycyclic aromatic hydrocarbon PAH compounds was observed and monitored on two Norwegian product tankers. The tankers were loading their cargo with the hatches open during the monitoring period. One of the tankers loaded gas oil. This type of cargo is not volatile, and very low concentrations of the monitored chemical PAH compounds were found on this tanker. The second tanker loaded gasoline. On this tanker high concentrations of hydrocarbon compounds were found; benzene was as high as 55 ppm, toluene was as high as 34 ppm, hydrocarbon compounds in the C5-C7 range were as high as 570 ppm, n-hexane was as high as 25 ppm. The levels of PAH-compounds were low. None of the seamen working on the deck did use respiratory protective equipment during the work. The exposure of the deck crew to volatile hydrocarbon compounds ought to be reduced on product tankers. Better routines concerning the use of respiratory protective equipment is an immediate action which ought to take place. Loading volatile cargo like gasoline with the hatches open should be avoided.
在两艘挪威成品油轮上观察并监测了甲板船员接触挥发性碳氢化合物和多环芳烃（PAH）化合物的情况。在监测期间，这两艘油轮在舱口打开的情况下装载货物。其中一艘油轮装载柴油。这类货物不易挥发，在这艘油轮上发现所监测的化学PAH化合物浓度非常低。第二艘油轮装载汽油。在这艘油轮上发现了高浓度的碳氢化合物；苯高达55 ppm，甲苯高达34 ppm，C5 - C7范围内的碳氢化合物高达570 ppm，正己烷高达25 ppm。PAH化合物的含量较低。在工作期间，甲板上工作的海员均未使用呼吸防护设备。在成品油轮上，应减少甲板船员接触挥发性碳氢化合物的情况。关于使用呼吸防护设备的更好程序是应立即采取的行动。应避免在舱口打开的情况下装载像汽油这样的挥发性货物。
