Final answer:
Dead animals and animal organs used in labs or research must be autoclaved or chemically decontaminated prior to disposal, according to biosafety practices, to prevent biohazard risks.
Step-by-step explanation:
Prior to removal from the building, dead animals and animal organs used in labs or research must be either autoclaved or chemically decontaminated. This is in accordance with biosafety practices and procedures established to prevent biohazards from impacting public health and the environment. Autoclaving is a sterilization process that uses high-pressure saturated steam to eliminate any biological agents. Chemical decontamination involves using a chemical solution, such as formalin or a bleach solution, to neutralize potentially infectious agents. Leaving such material in labs for further study or disposing of it in regular trash bins is not an option due to the high risk of contamination and spread of disease.
These procedures ensure that all potential biohazards are rendered safe before being included in the waste stream. It is important to recognize the international symbol for biohazards and to adhere to all regulatory guidelines when disposing of biological waste to maintain a safe and clean environment within research facilities.
