1. MSDS M aterial S afety D ata S heets Contain important chemical information such as: Toxicity Health effects Reactivity Storage Disposal...and more

2. More Information All pertinent information about the physical properties of a chemical such as odor, color, melting and/or boiling point, density, etc. All health risks and appropriate precautions for handling a chemical such as the use of gloves, hood, lab coat, special breathing apparatus, etc.

3. Who is an MSDS for? For those working with the material in a occupational fashion Employees who work with chemicals Employees who need to know the proper storage of chemicals Emergency responders (fire-fighters, haz mat teams, etc.) Not for consumers Example: An MSDS for paint is not necessary for someone who uses a can of paint once a year, but is important to someone who paints in a confined area for a living What does an MSDS look like?

4. Why Do We Keep MSDS Sheets? The U.S. Government's Occupational Safety and Health Administration (OSHA) is responsible for the Hazard Communication Standard 29 CFR 1910.1200. The purpose of this standard is ‘to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees. This transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, material safety data sheets and employee training.’ I.e. Because companies are required to

5. MSDS of Acetic Acid Acetic acid comes in numerous forms depending on the concentration of the acid in water. For instance, we use ~ 4.5% acetic acid in making salad dressing (it is commonly called vinegar). Acetic acid is also sold in more concentrated formulations for use in the chemistry laboratory. Glacial acetic acid is 17.4 M and is considered 100%. It is the strongest form for the acid and would kill you if you drank it. The MSDS for glacial acetic acid would be different from that for vinegar but the names “acetic acid” are the same, the chemical formulas are the same, the formula weights are the same, etc.
