How to classify and manage chemical supply?
The classification management of chemical supply mainly includes classifying them into two categories: organic and inorganic, and further subdividing them for storage.
Separation of inorganic and organic reagents: Inorganic and organic reagents should be stored separately to avoid unnecessary risks. Inorganic reagents can be classified according to acids, bases, salts, etc., while organic reagents can be classified according to functional groups, such as hydrocarbons, alcohols, phenols, ketones, acids, etc.
Classification management of hazardous reagents: Hazardous reagents must be classified and separated, and cannot be mixed. For example, flammable liquids such as organic solvents, ethanol, ether, and acetone should be stored separately and kept cool, ventilated, and away from sources of ignition. Flammable solids such as sulfur, yellow phosphorus, magnesium powder, and aluminum powder should also be stored separately and kept ventilated and dry. Strong oxidants such as potassium chlorate, nitrate, peroxide, etc. should be stored in a cool and ventilated place, avoiding mixing with reducing substances or combustibles.
Special management of highly toxic reagents: Highly toxic reagents such as potassium cyanide and arsenic trioxide should be carefully stored by dedicated personnel, and strict records should be kept when using them to avoid accidents.
Management of other special reagents: Light decomposed reagents such as silver nitrate, potassium permanganate, etc. should be stored in brown bottles and kept in a cool and ventilated place. Reagents that are prone to corrode glass, such as hydrofluoric acid, fluorine-containing salts, sodium hydroxide, etc., should be stored in plastic reagent bottles to prevent corrosion of glass.
Through the above classification management measures, the safe use and storage of chemical drugs can be effectively ensured, and accidents can be prevented from occurring.
