Methylene chloride is predominantly used as a solvent. The acute effects of methylene chloride inhalation in humans consist mainly of nervous system effects including decreased visual, auditory, and motor functions, but these effects are reversible once exposure ceases.

1、Put on gloves to protect your hands and skin; butyl rubber, neoprene and polyethylene are the best skin protectors when dealing with the acid. Put on a gas mask and wear long clothes and protective goggles. Open all the windows in your bathroom and nearby rooms. Open all doors to create air flow.

Nitric acid (HNO3), also known as aqua fortis and spirit of niter, is a highly corrosive strong mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water.

Formic acid is a pungent-smelling substance which is colorless and corrosive. It is used in various day to day activities, such as dyeing and finishing in textile industries and tanneries.

A phenol is one of a number of chemically active compounds which are found throughout nature, especially in plants. Their molecules each include a hydroxyl functional group (OH) bonded to the ring of an aromatic compound — a molecule that includes at least one ring of carbon atoms.

Ethyl acetate is an important organic chemical raw materials. It can be used in the manufacture of acetamide, acetyl acetate, methyl heptyl ketone and others.

Acetic acid has corrosive. Its irritation has effect on steam eye and nose. So, we should be more careful in using the acetic acid. If the skin contacts with acetic acid. You should wash with water first, then use the soap to wash thoroughly.

Hydrogen peroxide has strong oxidation. So, you must be more careful when using. You must take off contaminated clothing if the hydrogen peroxide has contacted with your skin.

There are a large number of hydrogen chloride gas during the process of using hydrochloride. We can put the suction device in the container side and coupled with the fan, mist purifier, air duct and other equipment. That will make the mist exhausted.

HISEA CHEM could provide the complete set of nitric acid engineering services covers every stage. We take the latest technique to produce the nitric acid by the dual pressurization process.
