急性中毒现场及特殊作业场所气体采样方法

A gas sampling method for acute intoxicaton spot and special working place

为适宜急性中毒现场和特殊作用场所的气体采样而设计了导向采样法。该法以金属活塞三通为气体导向控制器,与采气管,连接管,抽气动力,样品收集器共同组成采样系统。导向采样法设计合理,经多年现场应用,操作简便安全,采集的气样准确可靠。为急性中毒原因调查及特殊作业场所劳动卫生学评价提供了可行的采样方法。

Wuhan provention & Treatment Center of Occupational Diseases(430071) The air flow control sampling method is designed for suiting the needs of the ai sampling on the acute toxication spots and the special working place. The sampling system consists o. a leading direction controller which is a metal piston of three-way-pipe, an air colleetor, conjective pipes, an air pump and a sampling collector. The design of this method is rational. After this method has been used on the spot for many years, it proves that the operatiod is safty and simplicity and the data of air sample collected are exact and rliable. This methd provides a feasible sampling method to investigaten the cause of acute toxication and to make hygienic valuation at special working place.
