Signs of safety or MSDS for chemicals

Introducing Safety Signs or MSDS for Chemicals (Industrial Raw Materials)

The most important issue that currently faces all the factories and manufacturing industries is the safety and security of its employees and the production of high-quality products. Most industries use chemicals as the primary material to produce their products. Storing, storing and transporting these chemicals in special packages is the most important goal of the plant. Obviously, the health of chemicals will improve the quality of the finished products.

Awareness of the chemical and physical properties of chemicals, safety and health of the individual ensures increased productivity in the industry. A sheet that fully describes the warning signs, safety and general characteristics of a chemical is known as the Material Safety Data Sheet (MSDS).

What is chemical safety information or MSDS?

MSDS stands for Latin Material Safety Data Sheet. This data sheet is a manual for the use of a chemical or a birth certificate of that particular substance. In the MSDS, information such as the general profile of the substance, physical and chemical properties, safety hazards such as flammability, pollution, corrosion, etc., chemical composition and structure of the substance, safety and protective measures, methods of storage and transportation ... Is inserted. Boiling Point, Melting Point, Explosion, Flammability, Density, Viscosity, Acidity, Vapor Pressure and Degree of Decomposition, Other Information contained in the MSDS Sheet is a chemical.

What is a hazard diamond for chemicals?

Due to the variety of chemicals and the dangerous levels of some of them in the industry, the need for familiarity with MSDS materials and the awareness of their hazards are essential for consumers and manufacturers. In order to achieve this, the American Fire Protection Association (NFPA) has developed a standard that is known as "Risk Danger".

The diamond is designed as a quadrilateral rhombus, each part of which is displayed with a specific color. Each color expresses the type of danger that that chemical produces. The severity and weakness of each of these hazards are defined in each individual section with numbers from 0 to 4. People who read this diamond and are in contact with a specific chemical can easily know the dangers of that substance. The following figure shows a dangers full of danger.

What is the classification of hazardous chemicals?

Hazardous chemicals are substances that cause very serious and immediate damage to people, their environment or materials. In terms of risk, chemicals are classified into six categories or in the term "class." All hazardous chemicals should be labeled with a rhinitis label. Hazardous chemical classes are reported as follows:

Class 1; Explosives: Class 1 explosives fall into 6 subgroups; first group: explosive with explosive (nitroglycerine) explosion; the second group: launch explosive Bombs); Group 3: Explosive explosives with high fire risk (fireworks); Group 4: Explosive explosives without fear of explosion (gunpowder and fireworks); Group 5: Explosives with low sensitivity; Group 6: Explosives with Very low sensitivity.
Class 2; gases: This category of materials is divided into three main categories of flammable gases, non-toxic and non-flammable gases and toxic gases (chlorine, ammonia and carbon monoxide)
Class 3; flammable liquids: These fluids are classified into two main categories of highly flammable liquids and low flammable liquids (ethylene ether, gasoline and acetone)
Class 4; Flammable Solids: Self-combustible materials are divided into three main categories. The first group is solids with their own combustion potential (white phosphorus), the second group, the solids in the wet state (calcium carbide), and the third group includes flammable solids (nitrocellulose and phosphorus).
Class 5; oxidizing materials: Oxides and peroxides are one of the most hazardous oxidizing chemicals. These materials are highly combustible with air oxygen and cause fire. Hydrogen peroxide, sodium hypochlorite, benzoyl peroxide and peracetic acid are oxidizing substances.
Class 6; toxic and infectious substances: This category of materials is among the most dangerous chemicals. The effects that these materials may have on themselves may persist for many years in a chronic way. Infectious substances, poisonous, radioactive substances, corrosive chemicals and magnetism are a variety of toxic substances. Cyanides, arsenic compounds, radioisotopes, HF, polyester and ... are examples of these materials.
