Dangerous reagent reachs his to save
From;    Author:Stand originally

Dangerous sex reagent or chemical danger are tasted, have can combustion, explosion, harm, corrode or the risky nature such as radioactivity. In be chafed, shake, bump, osculatory fire cause, treat water or be affected with damp be affected with damp, strong smooth illuminate, high temperature, when contacting substandard bound element to affect with other material, can cause intense combustion, explosion, toxic, burnable, deadly wait for calamity sex accident. Purchasing, in keep and using the process that all sorts of chemical danger taste, must deal with of country of strict comply with about the article of regulation and product manual. The chemical danger that the middle school may use in chemical experiment is tasted have the following kinds. Characteristic: Easy volatilize, treat bright fire easy inflammation; Steam and airy mixture reach explosion limit range, encounter bright fire, spark, electric spark to all can produce violent explosion.
1. Combustible liquid
Characteristic: Easy volatilize, treat bright fire easy inflammation; Steam and airy mixture reach explosion limit range, encounter bright fire, spark, electric spark to all can produce violent explosion. Example: Carbon of ester of acerbity second of benzine, benzene, toluene, alcohol, ether, second, acetone, aldehyde, chloric ethane, 2 vulcanization.
Custodial with the note when using: Should sealed (if build close bottle stopper) prevent dump and outside excessive, deposit in shady and cool and ventilated special cabinet, should be far from kindling (the implements that includes easy generation scintilla) with oxidizer.

2. Combustible solid

Characteristic: Catch fire the point is low, easy ignite, its steam or dust and air mix amount to certain level, encounter bright fire or spark, electric spark can intense combustion or explosion; Contact easy combustion with oxidizer or explode.
Example: Nitrify cotton, naphthalene, camphor, brimstone, red phosphorus, magnesian pink, zinc powder, aluminium powder.
Save reach the note when using: Deposit apart with oxidizer at shady and cool place, be far from kindling.
3. Spontaneous combustion is tasted
Characteristic: Contact with air easy cause spontaneous combustion because of slow oxidation.
Example: White phosphorus (Bai Lin is drama drugs at the same time)
Reach the note when using surely: Put in Cheng Shui's bottle, all immersion is in white phosphorus underwater, gasser, save at shady and cool place. The attention when using does not want to be contacted with the skin, prevent to temperature causes its spontaneous combustion and cause the burn that cicatrizations hard.
4. Treat water combustion matter
Characteristic: As intense as water reaction, produce flammability gas and emit a large number of heat.
Example: Calcium of potassium, natrium, carbonization, phosphor changes calcic, silicon to change natrium of magnesian, hydrogen sulfide to wait.
