Precautions for storage and use of pyruvic aldehyde

Pyruvic aldehyde has certain harm to the human body, so there should be many aspects in the storage and use of pyruvic aldehyde.

Basic effects of pyruvic aldehyde on the human body

Pyruvic aldehyde can be absorbed through the respiratory tract, digestive tract and skin. The skin absorbs slowly and is small, mainly in the first two ways.

Because of its high water solubility, acetone is easily dissolved and absorbed into the bloodstream and is rapidly distributed throughout the body.

Pyruvaldehyde is a micro-toxic type, and its toxicity is mainly anesthetic effect on the central nervous system. Pyruvic aldehyde vapor has a moderate irritant effect on the mucosa. Pyruvic aldehyde has no sensitizing effect on the skin, but has a mild irritating effect.

Therefore, due to the effect of acetone aldehyde on the human body, the following matters should be noted.

1. When the warehouse is in stock of acetone aldehyde, the warehouse can not be filled, and some passages should be reserved at the wall and other places to facilitate fire prevention inspection and effective fire rescue in the event of fire.

In the event of a fire, you can use anti-solvent foam, carbon dioxide, chemical dry powder, and yellow sand to extinguish the fire. Extinguishing with water may have no effect, but it can cool the containers in the fire, dissipate the steam, dilute the liquid flowing out, and protect the firefighters. When the acetone aldehyde is discharged, first cut off all the fire, wear a gas mask, gloves protective clothing, etc., rinse with water, dilute and discharge into the wastewater system.

2. Inhalation of pyruvic aldehyde vapor, inhalation of 1000ppm of vapor per day for 3 hours, will stimulate the worker’s nasal cavity for 7 to 15 years, making it dizzy and weak. The main symptoms are different degrees of anesthesia. The initial symptoms are fatigue, nausea, headache, dizziness, and excitement. Vomiting, shortness of breath, cramps and coma can occur in severe cases. Liquid can irritate the eyes. Swallowing can stimulate the digestive system and produce symptoms such as anesthesia and dislocation. The safe use of pyruvic aldehydes should be in glass or metal drums. The flow rate should not be controlled too fast during filling to prevent static electricity.

3. The glasses are exposed to pyruvic aldehyde. A pyruvic aldehyde concentration of 500 ppm will cause irritation, and 1000 ppm will have mild, temporary irritation. Liquid can cause toxic irritation.

4. Skin contact. Causes dryness, redness and cleft palate, mild irritation of the fluid, and minimal risk of absorption through intact skin.

5. Oral. It has a stimulating effect on the throat and stomach, a burning sensation in the lips and throat, and after a few hours of incubation period, dry mouth, vomiting, lethargy, acidity and ketosis, and even temporary disturbance of consciousness may occur. Taking a large amount will produce the same symptoms as inhalation.

6. Pyruvic aldehyde poisoning. Pyruvic aldehyde is mainly used for the inhibition and anesthesia of the central nervous system. In some people, high-concentration exposure may cause damage to the liver, kidney and pancreas. Due to its low toxicity, rapid metabolism and detoxification, acute poisoning under production conditions are relatively rare. Vomiting, shortness of breath, paralysis and even coma can occur during acute poisoning. After oral administration,
