The correct answer is

Using specialised hazardous waste disposal containers

The safest method for disposing of toxic dust is using specialized hazardous waste disposal containers. This is the correct answer because it addresses the inherent danger of toxic dust directly. Let's examine why the other options are incorrect:

  • Dumping it in regular trash bins: This is extremely dangerous. Toxic dust can contaminate other waste and potentially leach into the environment, harming people and ecosystems. Regular trash bins aren't designed to contain hazardous materials.
  • Releasing it into the air for dilution: This is incredibly irresponsible and potentially harmful. Toxic dust particles can be inhaled, leading to serious health problems. Dispersion doesn't eliminate the hazard; it simply spreads it.
  • Sweeping it into open areas: Similar to releasing it into the air, sweeping toxic dust into open areas spreads the contamination, posing risks to wildlife, water sources, and people.
  • Using specialized hazardous waste disposal containers: This is the only option that properly addresses the hazard. Specialized containers are designed to prevent leakage, are often labeled for clear identification, and are handled according to strict regulations to ensure safe and proper disposal.

Therefore, only the use of specialized hazardous waste disposal containers guarantees the safety of both the environment and people.
