Rinse mouth.Do NOT induce vomiting.IF ON SKIN (or hair):Take off immediately all contaminated

clothing.Immediately rinse with water for several minutes.Wash contaminated clothing before reuse.IF

INHALED:Remove person to fresh air and keep comfortable for breathing.Get emergency medical help immediately.Specific treatment(see below).IF IN EYES:Immediately rinse with water for severa

minutes.Remove contact lenses,if present and easy to do.Continue rinsing.Get medical help

Description of necessary first aid measures

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

In case of skin contact: Wash off with plenty of running water.Consult a physician.

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

If ingestion: Rinse mouth with water.Do not induce vomit.Consult a physician.

Most important symptoms/effects,acute and delayed:/

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

DO NOT use neutralising agents or any other additives.

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

Special hazards arising from the chemical: This material is flammable and may decompose and burn at high temperature and fire and release toxic fumes.

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   emergeney   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 a pump and transport to a waste disposal site for disposal.

Precautions for safe handling: There should be suficient local exhaust in workplace.Operators should be trained  and  strictly  follow  the  operating  procedures.Operators  are  advised  to  wear  protective  masks, corosion-resistant protective clothing and rubber gloves.Operators should load and unload lightly during handling to prevent damage to the package.There  should be  leakage treatment equipment in workplace. There may be harmful residues in empty containers.

Conditions  for  safe  storage,including  any  incompatibilities:Store    in     a    cool,dry,well-ventilated 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,alkalis,flammable  materials,ete., and should not be mixed.The storage area should be provided with suitable materials to contain spills.
