Dizziness, headaches, and weakness occurred among three men after short-term hydrocarbon exposure during improper welding procedures in a closed container. Symptoms were related to objective evidence of vestibular and cognitive dysfunction. Symptoms and abnormal test results persisted for 6 to 18 months. Simulation of the accident failed to demonstrate likely exposures except aliphatic hydrocarbons, well within the permissible exposure levels. Short-term exposures to neurotoxins may lead to long-term central nervous system abnormalities.
在一个封闭容器内进行不当焊接操作期间，三名男子短期接触碳氢化合物后出现头晕、头痛和虚弱症状。这些症状与前庭和认知功能障碍的客观证据有关。症状和异常测试结果持续了6至18个月。对该事故的模拟未能显示出除脂肪烃之外的可能接触情况，而脂肪烃的接触水平完全在允许范围内。短期接触神经毒素可能导致长期的中枢神经系统异常。
