Final answer:
Contaminated films removed from the mouth must be handled with gloved hands to prevent cross-contamination and ensure biosafety. Proper PPE should be worn, and strict disposal and decontamination protocols must be followed.
The correct option is 1.
Step-by-step explanation:
Once films are removed from the mouth, they should be handled only with gloved hands. This is because they are considered contaminated due to exposure to oral bacteria and potentially other pathogens. As per biosafety guidelines, it is important to avoid direct contact with contaminated materials to prevent the transfer of infectious agents.
Additionally, when working in a lab setting, it’s crucial to adhere to safety protocols which include wearing personal protective equipment (PPE) such as gloves, goggles, safety aprons, and using proper disposal methods for biowaste to minimize cross-contamination and ensure a safe work environment.
Contaminated waste must be treated appropriately, often through processes like incineration or autoclaving, and any contact with skin should be followed by proper cleaning and disinfecting procedures.
The correct option is 1.
