Description of necessary first aid measures

If inhaled:Quickly leave and move to a place with fresh air.Keep the airway unobstructed.If breathing is difficult,give oxygen.If breathing stops,give artificial respiration immediately.Consult a physician.

In case of skin contact: Remove contaminated clothing and rinse with plenty of running water.

In case of eye contact: Rinse thoroughly with plenty of running water for at least 15 minutes and consult a physician.

If ingestion: Rinse mouth with water.Consult a physician.

Most important symptoms/effects,acute and delayed:/

Indication of immediate medical attention and special treatment needed,if necessary:/

Suitable extinguishing media: Use foam,dry powder,water spray,etc.

Special hazards arising from the chemical: Flammable liquid.Its steam can form an explosive mixture with air.It can explode when exposed to high heat or open flame and release toxic gas.

Special protective actions for fire-fighters: Firefighters must wear air breathing apparatus,fire-fighting suits and protective gloves to extinguish in the upwind direction.Whenever possible,remove the container from the fire to open space and use spray water to cool unopened containers.

Personal precautions,protective equipment and emergency procedures: It is recommended that emergency personnel wear protective masks and fire protective overalls.Do not touch the spill directly.

Environmental precautions: Isolate contaminated areas and restrict access.

Methods and materials for containment and cleaning up: Small amount of leakage:adsorption with sand or other inert materials.Do not allow products to enter restricted areas such as sewers.A large amount of leakage:building a dike or digging a pit to contain.Transfer to a tank truck or special collector with an explosion-proof pump and transport to a waste disposal site for disposal.

warehouse.Keep away from fire and heat.Protect from direct sunlight.The package should be sealed and not exposed to moisture.It should be stored separately from oxidants,flammable materials,etc.,and should not be mixed.The storage area should be provided with suitable materials to contain spills.

Information on the likely routes of exposure:Ingestion(swallowing),skin/eye exposure and inhalation Symptoms related to the physical,chemical and toxicological characteristics:

Acute health effects:

Ingestion can cause symptoms such as nausea,vomiting and abdominal pain.

Skin contact can cause redness and irritation.

Inhalation can cause cough,throat irritation.

Eyes contact can cause redness and irritation.

Chronic health effects:The substance defats the skin,which may cause dryness or cracking.Exposure to the substance may increase noise-induced hearing loss.
