MSDS, full Material Safety Data Sheet, is a document used to describe the correct safety operation and management of various materials. Its main purpose is to provide information on the physical properties, chemical properties, toxicity, fire, explosion and health hazards of specific materials. In the workplace, MSDS is a necessity to ensure the safety and health of employees.
the history of
MSDS can be traced back to the early 20th century, when the American chemical industry began to flourish, but at the same time there are some problems about industrial accidents and chemical hazards. The National Research Council (National Research Council) decided to set up a committee to study chemical safety issues and propose solutions. Under the impetus of this committee, MSDS was born and widely adopted. The general format of the

MSDS is developed by the U.S. Department of Labor's Health and Safety Administration (Occupational Safety and Health Administration, abbreviated as OSHA) and is used by many countries because of its rigorous structure and clear specifications.

MSDS usually includes the following nine parts:

1. product and manufacturer information: including product name, manufacturer name and address, emergency telephone number, etc.

2. Ingredient information: including chemical name, identification number, CAS number, content percentage, etc.

3. Physical properties: including appearance, color, odor, melting point, boiling point, relative density, etc.

4. Toxicity information: including acute toxicity, subacute and chronic toxicity, skin irritation, eye irritation, inhalation and accidental toxicity.

5. fire and explosion information: including material combustion characteristics, flammability, explosive, spontaneous combustion, etc.

6. Reactivity: including the stability of the substance, decomposition products, setting and heating, etc.

7. Storage and use conditions: including storage temperature, humidity, ventilation conditions, storage time, etc.

8. Waste disposal: including waste treatment and disposal methods, restrictions and requirements for treatment and disposal.

9. Other information: including recommendations for use, personal protective measures, device protection, emergency control measures, etc.

For MSDS, it is generally believed that it is only useful for chemical companies or factories, but in fact, it is useful for everyone. Some chemicals may be used in the home, such as detergents, herbicides, pesticides, etc., these are potentially dangerous chemicals that need to be properly located and stored. In addition, if your work is related to chemistry, you need to know the contents of the MSDS to ensure the safety of yourself and your colleagues.

finally, it is necessary to make it clear that MSDS is not a substitute for the personal responsibilities and obligations of employees. Employees need to understand their responsibilities and obligations at work and strictly abide by the relevant regulations and systems. MSDS is only an auxiliary tool to provide relevant information and prompt risks. Only when employees use them responsibly can they truly achieve the purpose of ensuring occupational health and safety.
