Final answer:
An MSDS is a document providing essential information on handling and disposing of chemicals safely. It is critical to reference the MSDS when working with new substances, and to follow strict guidelines for disposing of hazardous waste as per EPA regulations.
Step-by-step explanation:
An MSDS is a document that provides information on the hazards, handling procedures, and safe disposal of chemicals. When working with new chemicals, it is crucial to consult the safety data sheets as they contain vital details about the safe handling of these substances and the risks they pose to both health and the environment.
Additionally, it is important to follow proper disposal methods for these chemicals since many cannot be discarded down the sink. The safety and environmental implications of improper disposal are significant; hence, these procedures are not just guidelines but essential practices for hazardous waste management.
Characteristic hazardous wastes are distinguished by their ignitability, corrosivity, reactivity, or toxicity. Specific regulations from the Environmental Protection Agency (EPA) guide the treatment, storage, and disposal of such wastes to mitigate potential hazards to human health and the environment. In a laboratory setting, one must always be aware of how to dispose of all waste materials, including biohazard waste, while adhering to safety guidelines and teacher instructions.
