Final answer:
The statement is true; Safety Data Sheets (SDSs) might not list all hazards associated with a chemical, making it crucial to handle all chemicals with maximum safety precautions.
Step-by-step explanation:
The statement is True: SDSs, or Safety Data Sheets, may not always disclose all the hazards of a chemical. These documents are designed to provide information on substances, including how to handle them safely and the potential dangers they pose to people and the environment. It is crucial to consult these sheets when working with new chemicals to ensure safe handling, storage, and disposal, as improper disposal, such as washing chemicals down the sink, can be hazardous.
When working with chemicals, it is also essential to refer to the hazard diamond, sometimes known as a "fire diamond," which provides a summary of various dangers associated with chemicals. However, the SDS and hazard diamond may not cover all possible hazards, especially if there are unknown or untested aspects of the chemical, or if the regulations allow for certain non-disclosure situations. Therefore, always handle chemicals with the highest level of safety to prevent risks to health and the environment.
