Final answer:
If hazmat is classified as FORBIDDEN, you must not handle, use, or transport it; it is too dangerous for a school lab setting. Follow all safety instructions for handling chemicals and dealing with accidents or spills, and ensure proper disposal of lab waste.
Step-by-step explanation:
If the hazmat is classified as FORBIDDEN, you should not handle, use, or transport it under any circumstances. This classification means that the material poses too great a risk to be managed safely within the context of a school laboratory or during transportation. Specific protocols and regulations, such as those from the United States Department of Transportation and the Environmental Protection Agency, dictate how to manage such materials effectively and safely. In a high school laboratory setting, you should always follow instructions carefully when dealing with any chemicals, especially those that are flammable or potentially harmful.
When working in a lab, it's important to remember that no food or beverages should be consumed, hands should be washed after handling materials, and appropriate disposal methods should be followed for waste. For example, chemical spills require immediate attention, and you need to notify your teacher right away. Meanwhile, certain waste materials must be sterilized before disposal. All these practices help ensure a safe lab environment when dealing with hazardous materials.
