Phosphine tlv

WebGeneral Description Aluminum phosphide is a dark gray or dry, yellow, crystalline solid. It reacts with moisture to give phosphine, a flammable and poisonous gas. Normally, phosphine will spontaneously ignite upon contact with air. If there is an excess of water, the phosphine fire will not normally ignite any surrounding combustible material. WebFumiSense Pro-Lo is a handheld Phosphine monitor for monitoring phosphine levels outside the fumigated stack/ silo/ ship to check for leaks and to ensure the level of PH3 is less than the TLV. Equipped with an inbuilt air sampling pump and with the ability to measure PH3 up to 20 ppm, it is the perfect tool for this application. The backlit OLED display …

Liver and kidney failure, convulsions, delirium and coma may also occur if a person is exposed to enough phosphine. Zinc phosphide affects animals the same way it can affect people. WebThe OSHA threshold limit value (TLV) for phosphine gas is 0.3 ppm. The odor is detectable at a concentration of 2 ppm. However, this odor threshold does not give adequate warnings regarding possible dangerous gas concentrations. For this reason, manufacturers of aluminum phosphide include ammonia-producing agents in the pellets as the more ...
