Industrial alkali is not a dangerous substance, is flake alkali a dangerous goods

According to the List of Hazardous Chemicals (2002), industrial alkalis (referring to the following) are hazardous chemicals

Hazmat No.: 82001

Sodium hydroxide (sodium hydroxide solution.

Caustic soda; Caustic soda, liquid soda, solid soda) UN number: 1823, 1824 sodium bicarbonate, not listed.

Flake alkali. It is a hazardous chemical.

Flake soda is classified as a Class I alkaline corrosive product by the "Classification and Marking of Commonly Used Hazardous Chemicals (GB13690-92)", which is a Class 8 dangerous product, and the hazard code is 1823. It is extremely corrosive.

Because flake alkali is extremely corrosive, its solution or dust splashed on the **, especially on the mucous membrane, can produce soft scabs, and can penetrate into deep tissues, leaving scars after burns.

Splashing into the eye not only damages the cornea, but also damages the deep tissues of the eye.

Safe handling: 1. Yuanju operators: must wear work clothes, masks, protective glasses, rubber gloves, rubber aprons, long rubber boots and other labor protection products when working. A neutral and hydrophobic ointment should be applied to **. The production workshop should be well ventilated.

2. Leakage treatment: Isolate the leakage polluted area, and set up warning signs around it.

Emergency responders are advised to wear gas masks.

Wear chemical protective clothing. Do not come into direct contact with the spill, rinse with plenty of water and put the diluted wash into the wastewater system. If the hail is leaked, it will be collected or discarded after harmless treatment.

No. Soda ash is sodium carbonate.

It is an inorganic compound that belongs to the salt in the classification and does not belong to the base. Soda ash is an important inorganic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze, and is also used in life washing, acid neutralization, food processing, etc.

Is soda ash a dangerous good.

Soda ash is a white odorless powder or granule at room temperature, absorbent, soluble in water and glycerin.

Soda ash is also known as soda, soda ash, alkali surface or messy washing alkali, according to the density of the mountain cover, can be divided into light soda ash and heavy soda ash.

Soda ash can be divided into industrial soda ash and edible soda ash according to different uses, and the only production methods of soda ash include laboratory method, Lu Bran method, and Hou's alkali method. Wait.

Summary. Is caustic soda a dangerous good?

Sodium hydroxide is a dangerous chemical, sodium hydroxide, the chemical formula is NAOH, commonly known as caustic soda, caustic soda, caustic soda, is a strong alkali with strong corrosiveness, generally in the form of flakes or granules, soluble in water (exothermic when dissolved in water) and forms an alkaline solution. Hazardous chemicals, such as hazard, corrosion, combustion, combustion, etc., are highly harmful chemicals and other chemicals that are harmful to the human body, facilities and the environment. Chemicals are divided into 8 categories according to their hazards:

Category 1: ** products; Category II: compressed and liquefied gases; Category III:

flammable liquids; Category IV: flammable solids, natural articles and flammable materials when wet; Category V: Oxidizing agents and organic peroxides; Category VI:

DU pesticide and infectious substances; Category VII: Radioactive materials; Category 8: Corrosives.

Flake alkali belongs to class 8 dangerous goods and belongs to the corrosive category. Flake alkali is extremely corrosive, and its solution or dust splashed on the **, especially on the mucous membrane, can produce soft scabs and can penetrate deep tissues. Scarring after a burning oak tremor.

Splashing into the eye not only damages the cornea, but also damages the deep tissues of the eye. <

Flake alkali belongs to class 8 dangerous goods and belongs to the corrosive category. Flake alkali is extremely corrosive, and its solution or dust splashes on the **, especially on the mucous membrane, which can produce soft scabs and penetrate deep tissues. Scars after burns.

Splashing into the eye not only damages the cornea, but also damages the deep tissues of the eye. If you accidentally splash on the **, immediately rinse with water for 10min; If it splashes into the eyes, it should be immediately rinsed with water or saline for 15 minutes, and then 2 nufolaine should be injected. In severe cases, be sent to the hospital immediately**.

The maximum allowable concentration of caustic soda dust in the air is: Operators must wear work clothes, masks, protective glasses, rubber gloves, rubber aprons, long rubber boots and other labor protection supplies when working. A neutral and hydrophobic ointment should be applied to **. The production workshop should be well ventilated.

Sodium hydroxide Naoh, potassium hydroxide KOH, barium hydroxide BA(OH), calcium hydroxide CA(OH), ammonia NH·HO

In the acid-base ionization theory, alkali refers to the fact that all the anions ionized in the aqueous solution are oh-; In acid-base proton theory, a base refers to a substance that can accept protons; In acid-base electron theory, a base refers to an electron donor.

Industrial alkali: industrial soda ash (sodium carbonate NA CO), industrial caustic soda (hydrovinyl sodium oxide NAOH), industrial heavy alkali (NAHCO). The purity and impurity content of industrial alkali (may contain heavy metals, etc.) meet the general industrial use, the process is relatively simple, and large-scale industrial production can be carried out, which is harmful to the human body.

Edible alkali: edible soda ash (sodium carbonate Na Co, the same molecular formula, but without the impurities of industrial soda ash) and edible baking soda (sodium bicarbonate NaHCO).
