Acetonitrile's first aid measures

First aid measures for acetonitrile

Skin contact: take off contaminated clothes and wash skin thoroughly with soapy water and clear water.

Eye contact: lift the eyelids and rinse with flowing water or normal saline. See a doctor.

Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, carry out artificial respiration immediately and seek medical advice.

Ingestion: if the patient is conscious, induce vomiting, wash the stomach and see a doctor.

Acetonitrile fire fighting measures

Hazard characteristics: flammable, its vapor and air can form an explosive mixture, which may cause combustion and explosion in case of open fire, high heat or contact with oxidant. It can react strongly with oxidants. There is a luminous flame when burning. It reacts violently with sulfuric acid, fuming sulfuric acid, chlorosulfonic acid, perchlorate, etc.

Harmful combustion products: carbon monoxide, carbon dioxide, nitrogen oxide, hydrogen cyanide.

Fire extinguishing method: spray water to cool the container, and move the container from the fire site to an open place if possible.

Extinguishing agent: insoluble foam, dry powder, carbon dioxide, sand. Extinguishing with water is invalid.

Emergency treatment of acetonitrile leakage

Evacuate the personnel in the leakage contaminated area to the safety area quickly, isolate them and strictly restrict their access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained positive pressure respirators and gas protective clothing. Do not touch the leakage directly. Cut off the leakage source as much as possible. Prevent it from flowing into restricted spaces such as sewers and flood drainage ditches.

Small leakage: absorb with activated carbon or other inert materials. It can also be washed with a large amount of water, which is diluted and then put into the wastewater system.

Massive leakage: build a dike or dig a pit for storage. Spray water cools and dilutes steam, protects on-site personnel, and dilutes leakage into incombustible substances. Use explosion-proof pump to transfer to tank car or special collector, recycle or transport to waste disposal site for disposal.

Acetonitrile handling and storage

Precautions for operation: strictly seal, provide sufficient local exhaust and comprehensive ventilation. The operation should be mechanized and automated as much as possible. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear filter gas masks (full face masks), self-contained respirators or ventilated respirators, rubber gas jackets and rubber oil resistant gloves. Keep away from kindling and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Keep away from inflammables and combustibles. Prevent steam from leaking into the air of the workplace. Avoid contact with oxidants, reductants, acids and bases. Handle with care to prevent package and container damage. Equip with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Emptied containers may leave harmful substances.

Storage precautions: store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants, reductants, acids, alkalis, inflammables and edible chemicals, and should not be mixed. Explosion proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials.
