目的了解某汽车行业铸造工人的劳动强度,为劳动保护提供依据。方法根据国标GB3869-1997《体力劳动强度分级》和中华人民共和国国家职业卫生标准GBZ/T189.10～2007进行,选择具有代表性的标杆岗位78个总计167人,用所测得的肺通气量计算劳动时间率、平均能量代谢率、劳动强度指数、劳动强度等级等指标。结果调查78个具有代表性的标杆岗位,劳动强度属于Ⅳ级的岗位占55.13%、属于Ⅲ级的岗位占24.36%、属于Ⅱ级的岗位占10.26%、属于Ⅰ级的岗位占10.26%。结论体力劳动强度属于Ⅲ、Ⅳ级的岗位占79.49%;长期有劳累感,因此对这些岗位可采取提高生产设备的机械化、自动化水平,改进操作方法或轮换操作等方式,减轻劳累感,促进工人身心健康,提高其生活幸福指数。
Objective To understand the labor intensity of foundry workers in a certain automobile industry and provide the basis for labor protection. The method was based on GB3869-1997 “physical labor intensity classification” and the national occupational health standard GBZ / T189.10 ~ 2007 of the People’s Republic of China. A total of 167 people were selected as the representative benchmark posts, with the measured lung ventilation Calculate the labor time rate, the average energy metabolic rate, labor intensity index, labor intensity and other indicators. Results A total of 78 representative posts were investigated. 55.13% of the workers belonged to Grade Ⅳ, 24.36% belonged to Grade Ⅲ, 10.26% belonged to Grade Ⅱ and 10.26% belonged to Grade Ⅰ. Conclusion The occupational manual workforce occupies 79.49% of the posts in grade III and IV. There is a sense of fatigue for a long time. Therefore, these positions can be used to improve the mechanization and automation of production equipment, to improve operation methods or rotation operations, to reduce the sense of tiredness and to promote workers Physical and mental health, improve their life happiness index.
