Step-by-step explanation:
Contaminated laundry must be handled according to strict protocols to prevent the spread of infection. It should be segregated and handled carefully to avoid exposure to and transmission of pathogens. Within a healthcare or laboratory setting, contaminated laundry should not be disposed of in regular trash bins, washed with regular laundry, or left in a patient's room.
Instead, it must be handled with protective gear, including a protective coat, face protection, and cut-resistant gloves, and then it should be cleaned or disposed of properly, following guidelines which often include incineration or autoclaving. Such procedures are crucial in maintaining a sterile environment and preventing healthcare-associated infections.
