Part Three:Hazard Identification

Health Hazard:irritation to skin and mucosa. High density will cause bronchitis, even bronchial asthma sometimes.Too much absorption will cause mouth cavity, gastritis, gastrorrhagia and  mucosa necrosis.

chronic effect: long-term exposure will cause headache,dizziness, anorexian,cough, rhinobyon and  chest pain.

explosion hazard: non-combustible

Part Four:Emergency Treatment

Skin exposure:take off pollutional clothes at once,wash in flowing water for 15 minutes at least and go to hospital.

Eye exposure:open eyelid and wash in flowing water or normal saline for 15 minutes at least,and go to hospital.

Inhalation:go to breath fresh air and keep the respiratory tract clear.If beath hard, oxygen therapy is needed.if breath stopped,artificial breath must be done at once and go to hopital.

Ingestion:wash mouth and drink some milk or albumen,and go to hospital.

Part Five:Fire protection

Extinguishing method:Firemen must wear full-body anti-acid bases clothes.

Extinguishant:day sandy soil.

Part Six:Leakage Emergency Treatment

First aid treatment:separate the leaking polluted area,control come-in and go-out.Emengency men should wear anti-dust mask,and wear anti-acid bases uniform.Don’t touch the leakage directly.If leakage is small,avoid cause dust,and use clean shovel to gather the leakage in closed container.If the leakage is much:use plastic cloth or canvas to cover it.And clear it away with professional guidance.

Part Seven:Operating and Storing

Operating attention:Operate in airtight condition,and local exhaust.Operation staff must be trained strictly and professionally,and they should obey operation regulations and rules.And operation staff should wear self-absorped,filtered and anti-dust mask,wearing chemical protected glasses,anti-acid bases uniforms and gloves are required.Keep away from the conbustibles and dust.Avoid to expose to soda and alcohol.Especially avoid to be exposed to water.Be careful when being loaded or uploaded,Protect its package and container from being damaged.Equip with leakage handling facilities.And the empty containers are possible to have injurant.

Storing attention:store the chemicals in cool,dry and breeziest warehouse.keep them away from inflammables and heat sources.The humidity should be keeped under 75%.Package must be sealed and dry.They should be stored separately from the combustibles,soda,and alcohol,they mustn’t be mixstored.Avoid storing for a long time,or it will go bad.Warehouse should have some suitable containers to gather the leakage.

Part Eight:Exposure Control and Individual Protection

Occupation Expoure limitation

China MAC(mg/m3):No standard at present

TLVTN：ACGIH 2mg/m3

TLVWN：No regulated standard yet

Project control:operation in airtight condition,local exhaust.Supply safe shower facilities and eye-washing facilities.

Breathing System Protection:When expose to the chemical dust,we should wear self-absorped, filtered,and anti-dust mask,when handling emergency,we suggest air respiratorresuscitator.

Eye protection:Wear chemical-safe protection glasses.

Body protection:Wear rubber anti-acid bases uniform.

Hand protection:Wear rubber anti-acid bases gloves.

Other protection:Forbid smoking,eat and drinking in working area.After work,take shower at once and change clean clothes.Put the hazard polluted clothes seperately and keep good sanitary habit.
