Which of the following guidelines for handling waste are given in the text?

Question

BlackTom AI · Accepted Answer

Let’s break down the question and each option to understand which guidelines are supported by the text.
Option 1: 'Place waste in containers labelled for the specific waste.' This aligns with proper waste handling practices, which emphasize segregation and labeling so that each type of waste is collected in its designated container for safe disposal or treatment.
Option 2: 'Always rinse chemicals down the drain with copious amounts of water.' This statement generally conflicts with standard hazardous waste procedures, which require containment and proper disposal methods rather than indiscriminate draining, as rinsing can spread contamination and violate regulations.
Option 3: 'Follow instructions.' This is a fundamental guideline, since the text would typically stress adhering to the specific procedures and safety protocols in place, which are conveyed through instructions.
Option 4: 'Contaminated paper towels should be placed in the trash.' In many contexts, contaminated disposable materials are treated as waste that should be collected in appropriate waste streams (e.g., biohazard or chemical waste) rather than simply thrown in the regular trash, so this statement could be inaccurate depending on the defined waste categories in the text.
Option 5: 'All waste should be combined at the end of an experiment.' Combining all waste into a single container is contrary to waste segregation principles, which require separating different waste types to prevent dangerous reactions and to comply with disposal rules.
In summary, option 1 is consistent with labeled, properly segregated waste handling, option 3 reflects the importance of following provided instructions, while options 2, 4 (depending on context), and 5 present practices that are typically inappropriate or unsafe according to standard waste-management guidelines.
