Influence On Environmental
Health hazard
Route of entry:
breathe in、ingestion、skin absorption.
Health hazard:
This product is central nervous system depressant. First be excited, and inhibit。Acute poisoning:
开场白和女生聊天Acute poisoning proceed from taking orally. Generally speaking, it has four grades adout excitement, hypnogenesis, anesthesia, stifler. If the patient get into the third ction or the fourth ction,it will loss of consciousness, mydriasis, irregular respiration, shock, mental efforts circulatory collap and respiratory arrest.
Chronic influence:
If you contact liquid inside for a long time, may cau eye irritation .It can produce chilling nsation and discomfort. As well as may cau headache, dizzy, tired, temperament, fremitus, queasy and so on.If drink to excess for a long time, may cau polyneuritis ,chronic gastritis, fatty liver, hepatocirrhosis , myocardial damage ,organic psychosis and so on . Also may cau skin irritation. Repeated or prolonged contact may cau skin drying.

Dangerous characteristic:
Flammability,mix smoke and air up with explosive gas mixture.
If meet with naked fire and high temperature,it can lead to decrepitation.
If meet with oxidizer, may cau chemical reaction or combustion.
In the fire,receptacle be heated may cau explosion.
The smoke is heavier than air,can spread from substory to distance and can backflash when meet
with naked fire.
Combustion( decomposition ) product:
carbon monoxide、carbon dioxide.

accidental relea measures
leakage emergency measures
Move the person who in the contaminated zone to the safety zone quickly,and they should be parated from the others.
初级职称Come and go in clo restraint.
Cut off the fire brand。
Emergency personnel should wear lf-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Don't touch the ooze immediately.
As far as possible, cut off the leakage point. To prevent it spreading to the wer and gutter that restricted quarter.
small quantity leakiness:
Sandy clay or other incombustible material absorbs it. Also can rin by plentiful water,and put the wage in wastewater treatment system。
large quantity leakiness:
Build diking or digging pit to take it in
十二怒汉影评
To cover with foam,and can reduce the damage the smoke had caud。
Move it to tank car or interceptor from explosion stack .
Transported it to the waste treatment site,and it can be treated or recycled.
英语专业Preventive measure
Preventive respiratory system:
Don't need special defend and prerve popularly. If contact with high concentration, you should wear filtermask (half-mask respirator).
Eye-protective:
Ordinarily, it have no u for especial protection。
Physical protection:
Wear antistatic work clothes。
Hand-protective:
Wear protective gloves as general job.
Other protect:
No Smoking at working site.
emergency treatment
Skin exposure:
In ca of contact , immediately wash skin soap and copious amounts of water .if irritation persists .Call a physician.
Eye exposure:
In ca of contact with eyes ,flush with copious amounts of water for at least 15 minutes .Assure adequate flushing by parating the eyelids with fingers. If irritation persists . Call a physician
Inhalation:
Remove victim to fresh air and provide oxygen if breathing is difficult. Call a physician。
Oral exposure:
If swallowed, wash out mouth with water provided person is conscious. Call a physician
Fire fighting measures:
As far as possible move the receptacle from fire brand to open territory。The jet of
water from the ho put out the fire.
extinguishing agent:
Insolubility foam、drymeal、carbon dioxide、sandy clay。
