Organic Chemicals 99.9% O-Xylene CAS 95-47-6
O-xylene is a colorless transparent liquid with a similar odor to toluene. The density is 0.88 (water =1), 3.66 (air =1), melting point -25.5 degree, ignition temperature 463, and explosion limit 1% ~ 7%. Used as a solvent and paint production, belonging to the low toxicity class.Flammable. The steam can form an explosive mixture with the air. Exposure to heat, open fire and strong oxidants can cause combustion and explosion hazards. Its vapor is heavier than air, and it can spread far along the low side. It's narcotic and poisonous.Colorless transparent liquid with aromatic smell. It can be mixed with ethanol, ethyl ether, acetone and benzene, and is insoluble in water.

Remove contaminated clothing and rinse the skin thoroughly with soapy water and clear water.
Lift eyelids and rinse with flowing or normal saline. Go to a doctor.
Quickly out of the scene to the fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, oxygen is given. If breathing is stopped, artificial respiration is carried out immediately. Go to a doctor.
Drink plenty of warm water and urge vomiting. Go to a doctor.
Flammable, vapor and air can form explosive mixture, in case of open fire, high heat can cause combustion and explosion. It can react strongly with the oxidizing agent. It is easy to produce and accumulate static electricity when the velocity is too fast. Its vapor is heavier than air and can spread to a relatively low level at a relatively low level.
[harmful combustion products]
Carbon monoxide and carbon dioxide.
[fire extinguishing method]
Spray cooling container, if possible, move the container from the fire to the open. Fire extinguishing agents: foam, carbon dioxide, dry powder and sand.
Store in a cool, ventilated storeroom. Stay away from fire and heat. The temperature of the reservoir should not exceed 30 degrees C. Keep the container seal. It should be kept separately from the oxidizing agent and avoid the mixture. The use of explosion-proof lighting, ventilation facilities. It is forbidden to use mechanical equipment and tools that are easy to generate sparks. Emergency handling equipment and suitable storage materials should be provided in the storage area.
