Storage of hazardous materials and its storage
Kian Petroleum Company is an international specialized company in the petrochemical industry incompliance with international standards of materials storage
To store hazardous materials, one must be fully aware of its physical and chemical properties and classify and pick the goods according to the danger they pose
otherwise one should expect fire, explosion, gas and steam leakage, and It even had the complete destruction of the warehouse
For this purpose, the following information should be obtained from the seller when buying
Physical and chemical characteristics of the product
Safety information and instructions related to firefighting, first aid and removal of environmental pollution
Transportation and storage
Storage conditions
Protective clothing required while working
Date of production and expiration of goods materials
Classification of hazardous substances
International systems must be followed to store hazardous materials. Information required In international standards such as OSHA and NFPA, methods have been developed that can
be briefly classified as hazardous products as follows
Flammable and explosive materials: These materials are solid, liquid and gas
A: Flammable solids (such as wood, rubber, fabric, paper, etc
Identification mark: A mark with a label
Lozenge-shaped, with white background and vertical red lines and black flame on top of it)
B: Solids that react with water such as carbide, sodium, potassium and
Identification mark: a mark with a sticker in the form of a rhombus and a blue background and a white flame on top of it
A: Materials that have the ability to ignite spontaneously. (Solid organic matter)
Identification mark: A rhombus-shaped mark with a white background at the top and red at the bottom and a black flame
Explanation: Keep in mind that powdered solids, such as organic powders including coal dust and wood, will burn like explosives if dispersed in the environment if conditions allow
liquids
: Liquids can be classified into two categories: light and heavy materials . Liquids that have flammable vapors under normal conditions (25 ° C and 760 ml Hg) are light liquids such as
gasoline, alcohol, acetone, and so on. In terms of fire, they should be considered as a class of flammable gases, and in controlling them, safety measures should be taken. Heavy
liquids that normally do not have vapor but, as soon as they are heated, provide the steam needed to ignite them. Although heavy flammable liquids such as kerosene, diesel and the
like are not dangerous under normal conditions, safety instructions must be followed when storing them
E: Gases: Gases should also be classified and then stored. Such as oxygen, toxic gases, flammable gases and the like
All of these materials ignite when mixed with flammable air or in the presence of a fire source such as electric or stationary sparks, mechanical friction, or hot surfaces, so special
storage must be provided to store them. . In particular, cylinders containing oxygen gas should not be stored alongside other flammable gases
Identification mark: Lozenge-shaped sticker, red background with white flame on top
