1. Flammable Chemicals
Common flammable liquids are: acetone, ether, methanol, ethanol, benzene, and other organic solvents; it is characterized by a low boiling point, is volatile, is flammable in water, and even cause explosions. Therefore, it is necessary to store in a cool, dark, well-ventilated area and away from the fire sources.
Flammable solids are red phosphorus, sulfur, naphthalene, nitrocellulose; it is characterized by a low ignition point, heat, friction, impact, or strong oxidizers that can cause severe sustained combustion and explosion. Therefore, it is necessary to store in a cool, dark, well-ventilated area and away from the fire sources.
Flammable gases include hydrogen, acetylene, and methane, which are characterized by combustion caused by impact and heating, and will explode when mixed with air in a certain ratio. Therefore, ventilation is required when using. It should not be stored in the laboratory if it is cylinder gas.
White phosphorus is prone to spontaneous combustion, which is characterized by air oxidation, heat release, reaching the ignition point, and causing spontaneous combustion at the appropriate temperature. Store a small quantity of water and a large quantity of wax seals.
The inflammable substances in water are sodium and potassium, which are characterized by violent reactions with water, producing combustible gases and releasing heat, which will cause combustion. It should be stored in kerosene and not in contact with water.
2. Explosive Chemicals
Explosive chemicals include ammonium nitrate, picric acid and trinitrotoluene. They are characterized by a strong reaction caused by friction and impact or high heat, releasing a large amount of gas and energy, know as a violent explosion. Storage should be kept in a cool, dark place, and care should be taken to ensure that the handle is secured.
3. Toxic Chemicals
Potassium cyanide, arsenic trioxide, barium chloride, hexachlorocyclohexane. It is characterized by highly toxic, a small amount of invasion of the human body ( ingestion or contact with the wound ) caused by poisoning, or even death.
4. Strong Oxidizing Chemicals
Potassium nitrate, potassium chlorate, hydrogen peroxide, sodium peroxide, potassium permanganate. It is characterized by intense oxidation, acid exposure, heating, and mixing with organic matter, flammable drugs, reducing agents, etc., resulting in combustion or even explosion due to reactions. It should not be stored with combustibles, explosives, reducing agents, etc.
5. Hydrogen corrosive chemicals
Strong acid, strong base, hydrogen fluoride, bromine, phenol. It is characterized by strong corrosion, corrosion and damage caused by contact with objects, human skin, and chemical burns. Should not be stored with oxidants, flammable and explosive drugs.
