Welding is a common industrial process associated with various health hazards. The aspect of duration of hazard exposure among welders at their workplace has been studied to limited extent in India.
To assess the duration of occupational hazard exposure and its association with symptoms among the welders.
A cross-sectional study was conducted amongst 106 welders in North Delhi. Data was collected using a questionnaire containing items to assess the socio-demographic profile, their medical history and individual hazard exposure.
Majority of them were involved in skilled/semi-skilled job (n = 99; 93%). The predominant nature of work for majority was manual. More than half reported their work to be physically hard (n = 56; 53%), involves much lifting of weight (n = 61; 57%), and is dangerous (n = 59; 56%). Dust/smoke followed by noise was reported to be most common hazards at the workplace by them. Most of them were suffering from eye related symptoms (n = 63; 59%) followed by skin conditions (n = 28; 26%). Skin diseases were reported to be significantly common among group of welders who were exposed to dust and radiation for ≥4 hours in a day (P < 0.05).
Nearly half of the welders found their job to be dangerous and were being exposed to at least one hazardous substance at their workplace. Majority of them complained of eye symptoms. There is a need for health and safety training of this economically productive group.
焊接是一种常见的工业加工方式，会带来各种健康危害。在印度，对焊工在工作场所接触危害的时长方面的研究还很有限。
评估焊工职业危害暴露的时长及其与症状的关联。
在北德里的106名焊工中开展了一项横断面研究。通过一份包含评估社会人口统计学特征、病史及个人危害暴露情况的问卷来收集数据。
他们中的大多数从事熟练/半熟练工作（n = 99；93%）。大多数人的主要工作性质是体力劳动。超过半数的人表示工作体力消耗大（n = 56；53%），需要频繁搬运重物（n = 61；57%），且工作危险（n = 59；56%）。他们报告工作场所最常见的危害是粉尘/烟雾，其次是噪音。他们中的大多数人患有眼部相关症状（n = 63；59%），其次是皮肤问题（n = 28；26%）。据报告，在每天接触粉尘和辐射≥4小时的焊工群体中，皮肤病显著更为常见（P < 0.05）。
近半数焊工认为自己的工作危险，且在工作场所接触至少一种有害物质。他们中的大多数人抱怨有眼部症状。对这个具有经济生产力的群体进行健康和安全培训很有必要。
