Phosphine detector is mainly used in granary fumigation project, some test the concentration in the fumigation process, the general selection range is 0-2000ppm, the other is to test the residual concentration after fumigation, the range is generally selected 0-20ppm. Many customers choose portable pumps that test the fumigation process through the sampling point and carry the residual test with them.
Phosphine gas has high efficacy to stored grain pests (except mite) at different insect stages. It can enter the insect body through the respiratory system, act on the respiratory chain of cell mitochondria and cytochrome oxidase, and kill the insect. It is mainly used for fumigation of granaries and tobacco, and can measure the residual concentration after fumigation and fumigation.
1. The main causes of phosphine poisoning are the following:
(1). Phosphine is a commonly used highly efficient fumigation insecticide, which is widely used in the fumigation and insecticide killing of grain, fur warehouses and cabins. Improper use, poor protection or accidental leakage can cause acute poisoning of operators and even surrounding residents.
(2). During the production, storage and transportation of phosphorus metal compounds, if the moisture is poor, the air humidity is too high, the absorption of water or acid can also produce phosphine, resulting in poisoning.
(3). In the production and use of yellow phosphorus, as long as there is yellow phosphorus combustion smoke can have phosphine, which is due to the low price of phosphorus oxide phosphorus trioxide (P2O3) and hot water reaction to produce phosphine.
2. Prevention of phosphine poisoning:
(1). When using aluminum phosphine to fumigate and kill insects, you must wear an effective gas mask and strictly follow the operating procedures when entering the site. After fumigation, thoroughly ventilate and detoxify, test with phosphine detector, and confirm that it is non-toxic before entering.
(2). Production, packaging, storage, transportation of aluminum phosphide, calcium carbide, ferrosilicon must be kept dry, strictly prevent moisture, strengthen ventilation. The same warehouse is strictly prohibited during transportation.
(3). Use the portable ph3 detector to monitor the concentration of phosphine in the environment to prevent accident.
The use of Xi'an Huafan Technology Co., Ltd phosphine detector has several benefits. Firstly, it helps to promote safety in industrial and agricultural settings where phosphine gas is used or produced. By detecting the presence of phosphine gas, workers can take appropriate measures to protect themselves from the toxic effects of the gas. Secondly, it helps to protect the environment by detecting and preventing leaks and spills of phosphine gas. This helps to prevent environmental pollution and reduce the negative impact of phosphine gas on the ecosystem. Lastly, it helps to reduce the risk of accidents and health hazards associated with the inhalation of phosphine gas.
