Precautions for Use

Precautions for ethylene gas: Operate in a closed system with overall ventilation. Operators must receive specialized training and strictly adhere to operating procedures. It is recommended that operators wear anti-static work clothes. Keep away from ignition sources and heat sources; smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas leakage into the workplace air. Avoid contact with oxidizing agents. During transfer, cylinders and containers must be grounded and bonded to prevent static electricity buildup. Handle with care during transportation to avoid damage to cylinders and attachments. Equip with appropriate types and quantities of fire-fighting equipment and leak emergency handling devices. Store in a cool, well-ventilated warehouse. Keep away from ignition sources and heat sources. The storage temperature should not exceed 30°C. Store separately from oxidizing agents; avoid mixed storage. Use explosion-proof lighting and ventilation facilities. Avoid using mechanical equipment and tools that may generate sparks. The storage area should be equipped with leak emergency handling equipment.

Ethylene gas is a compound composed of two carbon atoms and four hydrogen atoms, with a double bond between the two carbon atoms. Ethylene is a basic chemical raw material for synthetic fibers, synthetic rubber, synthetic plastics (polyethylene and polyvinyl chloride), and synthetic ethanol (alcohol). It is also used in the production of vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, ethanol, and explosives. Additionally, it can be used as a ripening agent for fruits and vegetables and is a proven plant hormone.
