粮油仓储、加工企业在进行化学熏蒸防虫灭虫过程中,常使用磷化氢等熏蒸剂,作业环境空气中存在磷化氢剧毒气体,为保证作业人员安全,必须为作业人员配备适宜的呼吸防护用品。粮油仓库属于密闭空间和缺氧危险场所,且作业期间有毒气体浓度达到或超过IDLH,因此,科学合理选用呼吸防护用品就显得非常重要。通过分析呼吸防护用品种类、适用条件,和粮油仓储加工企业具体情况,指导上述企业科学合理选用呼吸防护用品。
Grain and oil storage, processing enterprises in the chemical fumigation pest control pest control process, often using phosphine and other fumigants, operating environment, the presence of toxic gases of phosphine in the air, in order to ensure the safety of workers, workers must be equipped with appropriate breathing Protective Equipment. The grain and oil warehouse belongs to the confined space and the hypoxia-dangerous place, and the toxic gas concentration reaches or surpasses the IDLH during the operation. Therefore, it is very important to choose the respiratory protective article scientifically and reasonably. By analyzing the types of respiratory protection supplies, the applicable conditions, and the specific conditions of grain and oil storage and processing enterprises, we should guide the above-mentioned enterprises to choose the respiratory protection products scientifically and rationally.
