摘要
目的分析某口罩生产中存在的人因工程学风险,改善工人工作条件。方法使用快速上肢评估(RULA)法,对上海某企业口罩生产工艺进行风险识别,对员工手腕和手臂动作以及颈部、躯干和腿部动作进行评分,汇总后得到最终评分结果,并评估其风险等级。结果滤棉小卷剥离和滤棉小卷搬运两个岗位的人因工程学风险较高,其操作动作评估的最终评分均为7分。采取有针对性的改善方案,包括机械作业代替人工作业、生产工艺优化后,某口罩生产中人因工程学风险被有效降低。结论 RULA法在某口罩生产人因工程学研究与改善中能得到有效运用,预示该方法在人因工程评估领域可能具有广泛的适用性。
Objective To assess the human engineering risk in a mask production factory and then to improve the workers＇ working condition. Methods RULA （rapid upper limb assessment） was used to identify the ergonomics risks in a mask production factory,and to evaluate task severity and rank risk level for workers＇ wrist,arm,neck,torso and leg during the operation. Results Human engineering risks in two workplaces, namely the separation and lifting of filter jumbo were both ranked 7 points, which indicated both workplaces had high risks. After that, the improvement actions, including manual task replacement,the process optimization, were taken accordingly to reduce risk level. Conclusion RULA is an effective tool in assessing human engineering risks in a mask production factory, which indicated this tool can be used in more fields.
