Abstract

We reviewed over 220 cases of acute carbon monoxide (CO) poisoning and now report on 17 patients whose poisoning occurred from the indoor use of propane-fueled forklifts. All patients in this series presented with neurologic symptoms or persistent headache and were given hyperbaric oxygen to resolve their symptomatology. We investigated the concentration of CO in the exhaust emissions of 12 propane-fueled forklifts used in various workplaces in our location. The average CO concentration in the exhaust during engine idling was 36,000 parts per million (3.6%). This value decreased slightly to 30,000 ppm (3.0%) at working engine speed. Measurements of exhaust flow indicate CO production rates of approximately 60 liters per minute at working engine speed. These quantities of CO constitute a significant occupational exposure risk to workers using propane-fueled forklifts in unventilated indoor environments.

摘要

我们回顾了220多例急性一氧化碳（CO）中毒病例，现报告17例因在室内使用丙烷燃料叉车而中毒的患者。该系列中的所有患者均出现神经症状或持续性头痛，并接受了高压氧治疗以缓解症状。我们调查了在我们所在地不同工作场所使用的12辆丙烷燃料叉车尾气排放中的CO浓度。发动机怠速时尾气中的平均CO浓度为百万分之36000（3.6%）。在发动机工作转速下，该值略有下降，降至30000 ppm（3.0%）。尾气流量测量表明，在发动机工作转速下，CO的产生速率约为每分钟60升。在未通风的室内环境中，这些量的CO对使用丙烷燃料叉车的工人构成了重大的职业暴露风险。
