某舰船舰员长航时疲劳状况调查及原因分析

Investigation and analysis of fatigue among the ship crew of a certain naval vessel

目的分析和评价舰员疲劳状态和某舰艇舱室空气质量,找出可能导致舰员疲劳的原因,为维护和提高长航官兵的健康提供理论依据和指导意见。方法采用《疲劳自觉症状调查表》对舰员出航前后疲劳状况进行调查分析。采用Gasmet DX4035型傅立叶红外多组分气体分析仪对航行舰艇各个舱室的空气质量进行检测,并依据环境质量标准对舰艇舱室空气质量进行评价。结果 (1)经过1周的航行后,所有舰员疲劳症状明显加重,"身体"、"精神"、"神经感觉"3种疲劳因子均明显升高。(2)部分舱室空气中甲醛、SO2超标。结论舰员出海后较出海前疲劳程度明显加重;该舰某些舱室空气中部分有害气体含量超标,从而可能加重舰员的疲劳。

Objective To analyze and evaluate the fatigue status of the ship crew,as well as the air quality of the ship cabins,and to find out influencing factors for the fatigue among the ship crew,so as to provide theoretical evidence and guidance for the maintenance and improvement of the health of the ship crew during prolonged deployment at sea. Methods Investigation and analysis on the fatigue status among the ship crew both before and after deployment were made by using the questionnaire of《the Subjective Fatigue Symptom Checklist》. Air quality of the ship cabins was analyzed by using Gasmet DX4035 FT-IR multi-component air analyzer and assessed in accordance with Indoor Air Quality Standards. Results（ 1） One week after deployment,fatigue symptoms in all the shipboard personnel deteriorated significantly,and three fatigue factors including ＂ somatic＂, ＂ mental＂ and ＂ neurosensory＂ factors were all considerably increased.（ 2） The levels of formaldehyde and SO2 in some cabins exceeded the permissible limits. Conclusion The fatigue status among the ship crew after deployment at sea obviously deteriorated,as compared with that before deployment. The levels of harmful gases in some cabins exceeded the limits as specified in the standards,which could worsen the fatigue status among the ship crew.
