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

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.
