The chemical nature of piperazine is that it is exposed to fire and is highly flammable. When the combustion is decomposed, toxic nitrogen oxide gas is released. The toxic gas is released by heat. Corrosive.


Many people now have huge losses because they do not follow the precautions for the use of chemicals (such as chemical plant explosions in China).


Therefore, Haihang industry hopes that you can strictly observe the precautions for the use of the dangerous chemicals piperazine and avoid unnecessary losses.

The precautions for the use of piperazine are as follows

Risk description

Health hazard: A large amount of exposure to the chemical, inhalation or absorption through the skin, can cause weakness, blurred vision, tremors, epileptic seizures. In addition, the chemical can cause methemoglobinemia, affect blood oxygen carrying capacity, headache, dizziness, nausea. Eye contact causes severe irritation and burns. Irritating to the skin, can cause burns.

Chronic effects: The chemical dust or liquid, which is sensitizing to the skin and lungs, causing itchy skin, rash and asthma.

Explosion hazard: The chemical is flammable, corrosive and irritating, can cause burns to the human body and cause allergies.

First-aid

Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water for at least 15 minutes. Seek medical attention.

Eye contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.

Inhalation: Remove quickly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

Fire-fighting measures

Hazardous combustion products: carbon monoxide, carbon dioxide, nitrogen oxides.

Fire-fighting methods: Firefighters must wear gas masks, wear full-body fire-fighting suits, and put them on the wind.

Extinguishing media: water spray, foam, dry powder, carbon dioxide, sand.

Leakage emergency treatment

Emergency treatment: Isolation of contaminated areas and restrictions on access. Cut off the fire source. It is recommended that emergency personnel wear a dust mask (full face mask) and wear acid and alkali protective overalls. Use a clean shovel to collect in a dry, clean, covered container and transfer to a safe place. It can also be rinsed with plenty of water, diluted and placed in a wastewater system. If there is a large amount of leakage, collect it for recycling or transport it to a waste disposal site for disposal.

Handling and storage

Operational precautions: closed operation, local exhaust. Operators must be specially trained to strictly follow the operating procedures. Operators are advised to wear self-priming filter dust masks, chemical safety glasses, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. Avoid dust. Avoid contact with oxidants and acids. Lightly load and unload during handling to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.


Storage Precautions: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat. Keep the container sealed. It should be stored separately from oxidants, acids, etc., and should not be mixed and stored. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be provided with suitable materials to contain spills.
