・The types of reliable caustic soda are as shown from the following table, plus the qualities and assessment methods are chosen in JSIA (Japan Soda Industry Association) Standards, JIS (Japanese Industrial Standards), the Japanese Pharmacopoeia and the JSFA (Japanese Standards intended for Food Additives).
・Caustic soda is the most typical of the strong alkalis. Although there is no danger of it exploding or perhaps igniting, it does respond with various acids, such as hydrochloric acid, and is also neutralized and generates considerable exothermic heating of neutralization.
・It corrodes metals, like aluminum, sodium hydroxide flakes price tin, in addition to zinc. During this procedure, it generates hydrogen, which has the potential in order to behave as an mind-blowing gas.
・It is extremely hygroscopic, and absorbs the moisture, carbon, or sulfur dioxide in the air. It is also very deliquescent and absorbs moisture to form a great aqueous solution.
・When liquid caustic soft drink is diluted, the item generates a considerable amount of high temperature of dilution. Since this rapidly generates robust heat and the causing solution may spatter if the water will be carelessly poured involved with it, care must be obtained.
・Caustic soda quickly decomposes animal fibres. Although plant fabric are also decomposed, they have a higher resistance when compared with animal fibers. Though materials resistant to corrosion by caustic soft drinks include stainless steel, steel-epoxy resins, and fiber-reinforced plastics, steel and also rubber lined steel are the most frequently applied.
・Alkalis have a decomposing effect on proteins, which might gradually penetrate the particular deep tissues unless of course the adhered radical is completely removed. Especially, if the eyes are encountered with an alkali, considering that eye tissue will be rapidly affected causing a lowering or even loss of vision, great care should be used.
・Even a thin down solution can affect the actual tissue of the skin if it repeatedly rolls into contact with the skin, which can cause dermatitis or even chronic eczema.
・If the concentration of the solution is high, the affected tissue fast decomposes.
・If the remedy is swallowed by mistake, it causes irritation in the mouth, throat, wind pipe, or stomach.
・The inhalation of caustic soda dust or even mist causes various degrees of injury within the respiratory tract. Thus, typically the allowable concentration involving caustic soda airborne dirt and dust or mist upward in a working spot is specified seeing that 2 mg/m3 (upper limit).
・Close the actual lid or cover of the container so that it is airtight in order to avoid moisture absorption while in transportation.
・For travelling in drums, use boxcars, but if gondola cars are used, deal with the drums with sheets.
・In the lens case of consolidated transportation, keep acids clear of the caustic soda pop, and do not place the storage containers of caustic soft drinks on top of other bins containing organic chemicals.
・Since crystals are generally precipitated from liquefied caustic soda if the temperature lowers, usually do not expose it to low temperatures for long periods of time. The very cold point of common commercial liquid caustic soda is 5～12℃
・When solid caustic soda flakes manufacturer soda is being treated directly, or fluid caustic soda is it being handled, be sure to wear protective goggles and also rubber gloves, as well as wear rubber footwear or rubber apparel as required.
