Application of fumigant material and post-fumigation aerations must be by twopersons, with at least one person being a certified applicator. The secondindividual may be a worker under the direct supervision of the certified applicator,and the certified applicator is responsible for the safety of this worker.GAS DETECTION AND MONITORING DEVICESRevised labels for fumigants require the use of sensitive gas monitoring devices duringfumigant application and before warning placards can be removed from fumigatedstorages. Devices that provide adequate sensitivity include gas detector tubes andmatching pumps manufactured by Auer, Draeger, Matheson Kitagawa, MSA, andSensidyne.
Figure 1.23Detector tubes are sealed glass tubes filled with a specific reactive solid. Both ends of atube are broken off just before use, and one end is attached to a calibrated pump.Available pumps use a bellows, bulb, or piston-type syringe to draw a precise volume ofair through the detector tube (Figure 1.23). Discoloration of the solid material within thetube indicates fumigant presence, and the gas concentration, can be read directly from thescale on the glass tube. A reading of 2 ppm is shown in Figure 1.24. Although tubes andpumps manufactured by different companies may be very similar, accurate readingsrequire matching detector tubes and pumps from the same manufacturer. Do not mixseparate brands of equipment.Detector tubes are specific for a single fumigant. Auer, Draeger, Matheson-Kitagawa,MSA, and Sensidyne manufacture detectors that offer adequate sensitivity for labelrequiredmonitoring of hydrogen phosphide and methyl bromide.Resistance Management IssuesGrain storage facilities lend themselves to the development of insecticide resistance byvirtue of the enclosed, protected structures, limited immigration and emigration ofinsects, and the repeated use of the same chemicals without rotation between chemical
