基于LEC法的扒谷机危险源辨识
|
摘要
扒谷机是粮食仓储企业经常使用的机械设备之一。近年来因违规操作、维护管理不当,经常引发机械伤害、触电等生产安全事故。其中扒谷机配电箱内有粉尘、杂物,平衡配重不符合设备要求,防护罩缺失,配电箱外壳、电机接线盒破损,无漏电保护或漏电保护装置不灵敏是主要危险源。为提高作业人员对扒谷机危险性及作业风险的认识,提高作业人员安全意识,通过开展危险源辨识,确定危险等级,分别采取制定作业方案、设备移动方案,作业交底,及时清理粉尘、杂物,平衡设备配重,维护或更换隐患问题部位,设置警示标识等措施,实现对扒谷机危险源防控,延长设备使用寿命、确保作业人员的安全,防止或减少同类生产安全事故的发生。
Grain scraper is one of the mechanical equipment frequently used by grain storage enterprises. In recent years, mechanical injury, electric shock and other production safety accidents are often caused due to illegal operation, improper maintenance and management. Among them, the main hazards are that there are dust and sundries in the power distribution box of grain scraper, the balance weight does not meet the requirements of equipment, the lack of protective cover, the damage of the distribution box and the junction box of the motor, and the insensitivity of the leakage protection or even without the leakage protection device. In order to improve the operators' awareness of the danger and operational risk of the scraper, and enhance the safety awareness of the operators, the measures are adopted, including to identify the hazard and determine the risk level, to develop operation and equipment movement plan respectively, to clean dust and debris in time, to balance equipment counterweight, to maintain or replace the trouble parts, and to set the warning labels and so on. Therefore to prevent and control the hazards caused by grain scraper, prolong the service life of equipment, ensure the safety of the workers prevent or reduce the similar production safety accidents.
