Final answer:
Material Safety Data Sheets (MSDS) provide important information about chemical composition, hazard identification, safety measures, and disposal instructions for chemicals, as mandated by WHMIS 1988. They include a hazard diamond by NFPA and are essential for safe chemical management and regulatory compliance.
Step-by-step explanation:
Composition of MSDS (WHMIS 1988)
Material Safety Data Sheets (MSDS) are essential documents used to ensure the safe handling, storage, and disposal of chemicals in the workplace. They form a critical part of the Workplace Hazardous Materials Information System (WHMIS) 1988 and provide detailed information about the hazards of a chemical substance and the measures for protection.
The MSDS includes information on the chemical composition of substances, including if it is a compound formed by two or more different elements joined by chemical bonds. It also details the concentration of particles within a given space, which is crucial for understanding the potential risks associated with different concentrations of a chemical.
When working with any new chemical, it is important to consult its respective MSDS, which can often be found on websites such as msds.com. The MSDS will provide essential safety information, which includes, but is not limited to, how to correctly dispose of the chemical to prevent environmental harm, as disposal methods may vary and many chemicals cannot be simply washed down the sink.
In addition, the MSDS will often feature the National Fire Protection Agency (NFPA) hazard diamond, summarizing the primary hazards associated with the substance, which can include flammability, health hazards, and potential reactivity.
Under regulations by entities such as the United States Department of Transportation and the Environmental Protection Agency (EPA), the proper handling and disposal of hazardous materials are legally mandated, making the understanding of MSDS critical for compliance.
