Material Safety Data Sheets (MSDSs) and Safety Data Sheets (SDSs) are important resources for workplace safety and health. They provide important information on the properties, handling, storage, and potential hazards of chemicals and other substances. This information is intended to help workers understand the risks associated with working with these materials and to provide guidance on how to use them safely.

MSDSs and SDSs typically include information on the following:

• The chemical and physical properties of the substance, including its appearance, odor, melting point, boiling point, flash point, and explosive limits
• The potential health effects of the substance, including any short-term and long-term effects on the skin, eyes, respiratory system, and other organs
• The measures that should be taken to prevent or mitigate potential health effects, including appropriate personal protective equipment and emergency procedures
• The precautions that should be taken when handling, storing, and disposing of the substance, including any special storage requirements and disposal procedures
• The first aid measures that should be taken in the event of an accidental release or exposure to the substance

It is important for workers to be familiar with the MSDS or SDS for any substance they work with, and to follow the safety guidelines and precautions outlined in these documents. Employers are required to provide access to MSDSs or SDSs for all hazardous substances used in the workplace, and to train workers on the proper handling and use of these materials.
