Tetrahydrofuran spill treatment

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 fire protective clothing. Cut off the leakage source as much as possible. Prevent entry into restricted spaces such as sewers and flood drainage ditches.

Small leakage: absorb or absorb with sand or other non combustible 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 to receive; Cover with foam to reduce steam disaster. 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.

Waste disposal method: it is recommended to concentrate the waste and then burn it in open air outside a certain safe distance.

Skin contact: take off the contaminated clothes and wash the 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, give artificial respiration immediately. See a doctor.

Ingestion: drink enough warm water, induce vomiting, and seek medical advice.

Tetrahydrofuran handling and storage

Precautions for operation: closed operation, full ventilation. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear filter gas masks (half masks), safety glasses, anti-static work clothes 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. Prevent steam from leaking into the air of the workplace. Avoid contact with oxidants, acids and bases. During filling, the flow rate should be controlled and there should be a grounding device to prevent the accumulation of static electricity. 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: polymerization inhibitor is usually added to commodities. Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The storage temperature should not exceed 20 ℃. Prevent direct sunlight. Sealed package, not in contact with air. It should not be stored in large quantities or for a long time. It should be stored separately from oxidants, acids and alkalis. The lighting, ventilation and other facilities in the storage room shall be explosion-proof, and the switch shall be set outside the warehouse. Equip with corresponding varieties and quantities of fire-fighting equipment. Fire and explosion-proof technical measures shall be taken during tank storage. Cooling measures shall be taken for open storage tanks in summer. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. When filling, pay attention to the flow rate (no more than 3 M / s) and have grounding devices to prevent electrostatic accumulation. Handle with care to prevent package and container damage. During transportation, drive according to the specified route, and do not stop halfway.

Tetrahydrofuran fire extinguishing method

Fire extinguishing method: spray water to cool the container, and move the container from the fire site to an open place if possible. If the container in the fire site has changed color or generated sound from the safety pressure relief device, it must be evacuated immediately.

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