It is serious poison

In recent years, heterocyclic structures tend to choose synthetic raw materials of pesticides. It, mainly, because of unique structure of structures of heterocyclic showing unique high physiological activity. It can satisfy to the requirement of new pesticides in biological development. MHC INDUSTRIAL CO., LTD., making, mainly, it is more than fifty fine chemical products with serial products of plasters of polyurethane, a number of pine forest, electronic liquid crystal materials, customs chemicals, etc. Very corrosion acid, Hydrofluoric acid - inorganic acid of element fluorine also is designated chemically by a HALF. This boiling, the colourless decision mixing up with water, benzene, toluene, also concentrated sulfuric acid. The water solution of hydrogen fluoride, hydrofluoric acid contains hydrogen fluoride for 35.35 % in развес and is known for its ability of disintegration of many materials, especially oxides. It also shows extreme reactance with the glass reacting with quartz, SiO2 to create gas tetra silicon fluoride, SiF4 and water; which leaves a surface of a glass embodied. Thereof it is usually stored in steel tanks, cylinders or drums, or, in small amounts, in plastic bottles. Hydrofluoric acid - quite probably the most dangerous chemical to deal in Power Labs and therefore to have, to be processed with extreme caution. It is serious poison and possesses unique ability to get through a fabric nonionic distribution.

Contact poison, as we know, causes it deeply, originally painless burns, with later death of a fabric. Even 70 % flow, 2 % area of a body, can appear, fatal as the concentrated acid can cause system toxicity and possible cardiac arrest after intervention with a metabolism of calcium of a body. Acid of high concentration also a pure HALF extensively and inhalation just as the unique lungful of that gas will lead gases to almost certain death because of hypostasis of lungs.
