Final answer:
The correct answer is false; contaminated waste should not be placed in the nearest wastebasket but must be disposed of according to specific health and safety protocols.
Step-by-step explanation:
Proper Disposal of Contaminated Waste
When dealing with contaminated waste, it is false that it should immediately be placed in the nearest wastebasket. Proper disposal protocols are essential to ensure the safety of individuals and the environment. For instance, in the event of an accident involving hazardous materials, contaminated waste must be handled with extreme care, and specific disposal methods must be followed. The waste often requires removal by specialized professionals, and areas affected by contaminated waste, such as those with heavy doses of radioactive fallout, may need to be evacuated and decontaminated accordingly.
According to safety guidelines, such as Figure 21.7.9 and instructions provided in a lab setting (points 3, 4, and 5), contaminated waste should not be disposed of in standard wastebaskets or down the sink. Instead, one must recognize biohazard symbols, call a teacher or another authority in case of a spill or accident, and follow specific disposal instructions, which may include sterilization by autoclavage before adding to the waste stream. Two primary methods of waste disposal are through landfill and incineration, but these must be done in compliance with health and safety regulations.
