B类滤毒罐防护磷化氢性能评价探讨

摘要

磷化氢是粮食仓储企业使用效果最好的杀虫剂，是一种剧毒的气体熏蒸剂。所以对于从业人员来讲，安全防护就显得格外重要。长期以来粮食仓储企业一直使用自吸过滤式防毒面具（配套选用B类滤毒罐）为首选器材。近期业内对B类滤毒罐防护磷化氢的有效性提出质疑，为此，本文通过性能评价试验，说明B类滤毒罐防护磷化氢是有效的，并从理论上说明B类滤毒罐防护磷化氢是有科学依据的。%Phosphine is the best pesticides of the grain storage enterprise, and is the toxic gaseous fumigant. For users, it is important for the security. For a long time, the grain storage enterprise uses the serf-absorption filtering gas mask (selecting the B-type canister) . Recently, the protective performance against phosphine of B-type canister is doubted, through the test, this paper will explain the effective and scientific theory of B-type canister.
