Final answer:
All foreign bodies and tissues must be handled with protective clothing and equipment, cleansed with detergents and neutralizing agents upon contact, and disposed of through incineration or autoclaving. Instruments must be thoroughly decontaminated, followed by proper disposal in sterilized biohazard waste streams.
Step-by-step explanation:
When handling foreign bodies and tissues, especially in a medical or laboratory setting, there are strict procedures that must be followed to ensure safety and prevent contamination. Protective clothing such as a coat, face protection, and cut-resistant gloves must be worn to avoid direct contact with biological materials. If contact occurs, immediately wash the area with detergent and warm water, and then with a sodium hydroxide (NaOH) solution or bleach to neutralize any potential contaminants.
All contaminated waste must be treated to negate its biohazard risks; it should be either incinerated or autoclaved in a strong basic solution. Additionally, instruments that have come into contact with biohazards must be meticulously cleaned and soaked in a similar solution to ensure thorough decontamination. It's also important to recognize the international biohazard symbol and dispose of waste in designated biohazard waste streams, which have been sterilized by autoclave.
