What is the primary purpose of Material Safety Data Sheets (MSDS)?

Material Safety Data Sheets (MSDS) serve a vital function in ensuring workplace safety by providing comprehensive information about the hazards associated with chemicals used in various environments, including construction sites. The primary purpose is to inform employees, employers, and emergency responders about the potential risks of handling, storing, or disposing of these substances.

These sheets detail critical information such as the chemical's properties, health hazards, safe handling and storage procedures, protective measures, and emergency response actions in case of spills or exposure. By accessing this information, workers can take appropriate precautions to protect their health and safety.

The other choices, while they may touch on relevant topics, do not align with the main focus of MSDS. For instance, waste disposal guidelines are generally covered in a separate context related to environmental regulations, and project timelines or supplier lists fall outside the scope of safety data. Therefore, the emphasis on the hazards of chemicals makes the correct choice clear.
