摘要
为加强高原养路工的劳动卫生和劳动保护,制订合理的劳动定额和劳动制度,我们对海拔2679m、3191m、4300m高原养路工进行了劳动强度、职业危害调查。结果表明,随海拔高度增加,高原养路工生理负荷增加,劳动强度增加;劳动强度指数分别为16.0、18.4、22.3,总耗能量分别为6717.3、7855.5、9158.4kJ;单项体力活动时,海拔每上升1000m,生理负荷增加一个劳动强度等级。建议高原地区不同海拔高度劳动强度等级应有不同划分,高原不同海拔劳动制度应与平原不同,劳动定额也应相应减少。高原养路工劳动条件差,施工方式落后,粉尘浓度高,职业危害主要表现为呼吸系统疾病,尘肺病总检出率高达18.18%。
In order to study the labour hygiene and protetion for plateau roadmenders and to set the reasonable labour norms the labour intensity and occupational hazards of roadmenders working at 2679m, 3l9lm ,4300m above sea level were surveyed. The results showed that the physiological load and labour intensity increased with elevation of altitude. The labour intensity indices were 16,18.4, 22.3. Energy consumptions were 6717.3,7855.5,9158.4 kJ respectively. Under the single physical action, grade of physiological load increased with elevation of sea level per 1000m. We recommend that it is necessary to differentiate the labour intentity according to different sea level, and the labour norms should be decreased relevantly according to different sea level. The labour conditions of roadmanders working at plateau are very bad and the modes of construction are rather backward,so that the dust concentration is high.The morbidity of pneumoconiosis is more than 18.18%.
